How to move Bitcoin off of old computer?

I am getting ready to update my computer and I have to move some crypto wallets off of the computer before I do that as a safety. I havent looked at this stuff in years.
  1. I am using the Bitcoin-qt wallet on my pc and I have backed up the wallet.dat files to a few locations and burned them to a CD. Is that enough?
  2. I would really like to move the bitcoins and litecoins to a paper wallet. Can I make a paper wallet out of my bitcoin-qt or can I get the keys out somehow?
  3. If I send the bitcoins to coinbase is the IRS going to see that and tax me? Also by sending them to coinbase will that automatically give me the bitkash or all these spinoffs from bitcoin?
  4. Also a dumb question (been 6 years since I looked at this stuff) When I open the bitcoin-qt wallet where is my bitcoin address. The address if I wanted someone to send me bitcoin?
Thanks for the help.

This is going to sound stupid but...

A long while ago, as in approximately a decade ago. I was just killing time and reading articles. Bitcoin was pretty new and was reading about how people were mining with computers. Bitcoin was maybe a few months to a couple years old at the time.
I was reading an article and within the article there was a link to a new coin company that was trying to acquire clients by giving free coin just for setting up an account.
I was like, meh, why not? And did. And that's as far as it went. Divorce happened. Time passed and as far as I know, they're still 'out there' somewhere.
Lately, I've been wanting to try to locate them. I remember a file was saved to my PC. And therein lays my question.
Does anyone know file extensions I should search my old, archived drives for?
It's totally possible it was on one of the drives the failed or on one PC's that was stolen but still, it may be on one of like 15 IDE drives in a box.
Any help would be appreciated.
Edit: If I remember correctly, it was 10 Bitcoin.

How to Cold Store Your Cryptocurrency for Safekeeping

According to CipherTrace (which specializes in litigation tools and services for cryptographic markets), between 2018 and 2019, the amount of theft from cryptographic wallets exceeds $2 billion. Thefts and break-ins are caused by a variety of reasons: simple incompetence in cryptographic storage, as well as by companies that provide storage services. It is not unusual for holders of crypto currency to lose access to their wallets by themselves, one of the last known cases occurred in Ireland: ,57 million dollars couldn’t be confiscated from a detained drug dealer, which were stored in bitcoins. The problem was that the wallets keys were lost.
The most secure way is a cold storage — all account data and private keys are kept offline and all transactions are manual. This storage method is great because it is fully protected from hacking and interception of data, but it is not suitable for those who make daily transfers of cryptocurrency, it is simply inconvenient.
If you compare “cold and hot” wallets, you can give a simple example: A hot wallet can be compared to a wallet that can be lost and stolen. But you can always access your funds. A cold wallet is safe, and access to it is not permanent. You can also take or put money, but it will require a special code.
In this article we will tell you about the most popular types of cold wallets and we will analyze their pros and cons.

Types of cold wallets

All cold wallets have one common thing — the data is stored offline. However, there are several types of cold wallets, which differ in the degree of protection, physical embodiment and cost of the wallet.

Desktop wallet

Desktop wallets are also known for a high level of protection, in addition to the ability to store crypto currency offline. There are so-called “light” wallets weighing less than 1 gb, and “heavy” wallets weighing more than 1 gb. Two of the desktop wallets can be distinguished:

Exodus Wallet

Multicurrency wallet. It was created in 2016 and supports more than 100 crypto currencies, since 2019 has a phone application. The wallet allows you to export private keys that are created locally, and then to upload them back. Private keys can be discounted to removable media and downloaded only when the transaction is completed. If the user decides to leave private keys on the same computer where the wallet is located, keys are securely encrypted. In order to use your wallet ,there is no need to register or to download the entire blockchain — synchronization is taking place online. In addition to wallet services Exodus Wallet provides an integrated crypto-exchange. The installation file weighs 85 mb.

Bitcoin Core

Bitcoin Core is the official Bitcoin wallet. The size of the wallet is 160 gb, but according to the developers of the company, it’s better to give it a separate winchester with the size of 500 gb. From the security viewpoint, it’s suggested to install a security code or a seed phrase, which may consist 8 words. It is also suggested to copy wallet.dat file. — private wallet key, which will allow you to restore access to your funds.

Hardware wallets

Appears like a regular flash drive with an interface (screen, control keys). This wallet can safely store information about the balance and keys, full functionality is available only when connected to a computer, but the latest models have a special button that allows you to confirm the transaction without connecting to a PC. Each time the device offers to generate a new code-password to confirm the transaction, which significantly reduces the probability of hacking. After generating the code, you need to set a mnemonic phrase (seed) — it consists of 12 or 24 words, which are not related to each other in any way. Such type of wallets has a special protection system that allows you to connect even to potentially infected PCs. The wallets themselves won’t be affected by malware.
The obvious cons of hardware wallets are the following:
  1. It is also possible to lose a device that is so small in size.
  2. A physical device can easily fail due to a variety of damages.
  3. It is not recommended to buy such wallets from “hand”, even from friends, as they can be pre-installed with malware.
As you can see, storing crypto currency with a hardware wallets is very safe and secure, however you should take care about the device. Many people who hold a large amount of crypto currency, in order to not to lose a hardware wallet, store it in a safe deposit box, depriving someone of access to it.

Popular Hardware Wallets models

Trezor One

The first hardware wallet produced in 2013 by the Czech company Satoshi Labs. The device has an OLED display with a pin code, public addresses and Seed phrases. Trezor One has won recognition from users due to its multicurrency and affordable price ($65), it is also considered one of the most secure hardware wallets.
Ledger Nano S
The wallet was released in 2016 by the French company Ledger SAS. Distinctive feature from the other wallets, is the Secure Element controller, which meets banking standards and is certified CC EAL 5+. Also, in order to work with each crypto currency you need to install a special application for this currency on the device, it is not quite convenient, however more secure. The average price of the device is $85.
KeepKey
The purse was released in 2015 in the U.S.. Distinctive feature is OLED display — 256 by 64 pixels. Due to this, you can fully see both the address of the wallet, and the seed phrase. Also, the wallet has a built-in exchange service ShapeShift — an opportunity to exchange crypto currency without entering the exchange. The average price of the device is $50.
BitBox01
Ionos Schnelly’s wallet was invented in Switzerland. In size it’s almost the most compact among all representatives of the hardware wallets. A distinctive feature is the availability of a backup — the card can be multiplied and kept in several places, by analogy with the seed-phrase. In November 2020, support for these wallets will be discontinued, but all owners will be given a 30% discount on the new model. The average price of the device is $55.
CoolWalletS
Developed in Taiwan by CoolBitX, which has long been manufacturing components for Visa and MasterCard. As well as Ledger Nano S has a security standard CC EAL 5+. This wallet works only through smartphones, connecting to them through Bluetooch. The average price of the device is $100.

Paper Wallet

In the age of technological process, plain paper has become a rather reliable method for storing cryptocurrency. With the help of special services, such as bitaddress.org, you can generate public and private keys, then writing them down on paper. You can also print keys as a QR code. To accept transactions with such a wallet, you provide the sender with a public key. To access the funds, you need to find any online wallet that supports your crypto currency. Enter your private key into your online wallet, thus integrating your funds into the system. However, you should understand that after this procedure your wallet will become “hot”.
The best of this storage method — paper wallet is free, its safety depends only from you. When storing a paper wallet to protect it from the fire, water and aging. Also, do not tell other people about where your paper wallet is hidden.
The disadvantages of this storage:
  1. If your wallet is lost, it will be impossible to restore it.
  2. Exposed to a physical damage.
  3. After sending the transaction, you will have to create a new cold wallet.

Offline transaction signature

For this storage method, you will need two PCs. The essence is that the secret keys are never in contact with the Internet, but are stored digitally. Offline transaction method is suitable for people who do not make a daily transactions and have an access to two devices. The process is below:
  1. A hot wallet is installed on a PC with the Internet. The transaction is created without entering private keys and authorization.
  2. The file with transaction is copied and transferred to the second PC without Internet, where private keys are stored.
  3. The transaction is signed offline, copied and transferred back to the PC with the Internet.
In fact, you can do it with one PC and a USB drive. The USB drive will store private keys. Also, you can create a transaction without entering private keys and authorization, after disconnecting the Internet, connect the flash drive, sign the transaction, turn on the Internet. In this case, you should take care of the antivirus system.
The disadvantages of this method:
  1. Using two PCs or a USB drive involves a lot of actions, which is time consuming.
  2. You need to back up your keys in case your PC or flash drive fails.

Multi-signature wallet

This method implies the creation of a wallet, which can be only withdrawn on condition that the transaction is verified by a predetermined number of users. The maximum number of users who can hold private keys of the wallet- is 15. It is considered as one of the most reliable ways of storage, in fact private keys are not only stored offline, but also divided between different people. Often the wallet with multisignatures is used by large crypto-companies, whose management believes that individually employees can not spend the budget. Moreover, when creating this wallet, the number of required multisignatures is minimal. For example: if one of the six keys is lost, the remaining ones will be enough for the transaction.
The disadvantages of this storage:
  1. If most of the keys are lost, access to the funds cannot be restored.
  2. You will not be able to make transactions on your own without the participation of other key holders.

Private Key Fragmentation

The private wallet key consists of 64 symbols. The key is divided into several fragments. They don’t represent anything separately, but if you put all the fragments together, you can access the funds. The key fragments are similar to multisignatures, but in this case you don’t need a multisig-wallet, and the whole process can be done manually.
The disadvantages of this method:
  1. If one fragment is lost, access to funds will be lost.
  2. The maximum level of protection can only be reached when key fragments are distributed to different places, for example: bookshelf, safe deposit box, car. If you divide the key fragments and put them in different boxes — the required level of protection will not be achieved.
When writing down key fragments on paper, protect the key from fire, water and aging.

Conclusion

Digital currencies are not physically expressed and exist only in the digital code, so cold wallets that doesn’t have an access to the Internet, protect cryptocurrencies from the most important and common problem — hacker theft. However, holders of cold wallets need to understand that the safety of a private key depends only on them. There are different ways to store private keys outside the network, but each of them makes it difficult for the user to make transactions.
Hardware wallets that have been specifically designed for this purpose are considered to be the best option for storing cryptocurrencies. With their help it is possible both to store funds off the network and to make transactions easily, without risking the safety of a private key. If you use other cold wallets, it is recommended to combine them with hot wallets. Keep the required crypto currency for daily transfers on hot wallets, and keep all other crypto on cold wallets.

Found old wallet.dat, don't know how to identify the type of coins inside

Hi Everyone,
I found an old wallet.dat on a HDD. I'm trying to figure out how to identify the type of coins that are inside. Looks like a lot of alt coin are using "wallet.dat" just like bitcoin. I found by reading online that addresses are written in plain text inside the file, and indeed I can see next to "name=" some adresses.
Apparently, the first character of the address could identify the type of coin. In my case it's a "S".
What is the best way to find the coin associated with this wallet?

Thank you

Another one (old wallet recovery)

Hey everyone,
I've been out of the crypto game for a long time, but managed to dig up a wallet that I had stored on an old PC from early 2015. It wouldn't have much in it, maybe a few BTC at most, but it would be nice to recover it and cash out. The machine had Bitcoin Core installed, hasn't been connected to the internet since 2015, and is currently interstate - I've copied wallet.dat and that's all I have access to for now. The wallet is encrypted, backed up, copied to multiple secure locations, etc, and I remember the passphrase, but from what I've read in other threads, the private keys are the important part and I may need to do a "key dump"?
I tried installing Electrum and importing the wallet, but Electrum doesn't recognise the file. Am I right in thinking that the following would be the best solution?
  1. Download and install Bitcoin Core.
  2. Place wallet.dat into the appropriate directory.
  3. Open Bitcoin Core and allow it to "catch up" and download 240 GB worth of blockchain history.
  4. Possibly be forced to input the passphrase to access the wallet again, and transfer BTC out to an exchange of my choosing (unsure if this is how it would work at this stage).
Is there a way to recover the wallet without being forced to download hundreds of GB worth of data? I live in Australia, with typical Australia-tier internet, and it could quite literally take up to a week to download.
Apologies if there's any shortfall of knowledge on my end of things, it's been a long time since I've kept up with crypto and things seem to have changed quite a bit over the last four years. I appreciate any advice, and y'all are welcome to shame me on my relative ignorance, lol. Thanks!

Which security scenario is safest and why?

Hi All, wanted your opinions on which of the following is LEAST secure for storing your bitcoin and why.
A) TrezoKeepkey/Ledger hardware wallet with two copies of seed phrase engraved in metal and stored in safe deposit boxes in different banks
B) Paper wallet with private key split into 4 parts, engraved in metal and stored in 4 separate locations
C) Bitcoin Core wallet.dat file removed from implementation of Core and saved on six separate USB devises, stored in three different locations (duplicates in case of corruption/deterioration of one)
D) Coinbase... ok, ok, this ones just a joke :)

Thanks for your thoughts!

Edit: Maybe I should ask first, which is LEAST secure..

Because of many years of reading this sub and the advice provided here, on the worst day of my life, I didn't lose my bitcoin.

Update: Last week, I posted on reddit about my home being consumed by a fire and losing my three beloved cats and all of my worldly possessions. Our story was very well known as we offered a bitcoin reward for our cats (when they were presumed alive) and their were known for their Guinness World Records. I had listened to advice on a subreddit regarding placing my trezor in a firesafe that was ultimately destroyed and soaking wet. Yet, when I pulled my trezor from it, it was intact. Their product is awesome and the people at the company are even better. When they read my story, they offered to donate a portion of any sales** from this post to the Ferndale Cat Shelter, the local 501c Charity shelter my cats raised money for before they perished. I can’t say enough positive things about SatoshiLabs and anyone with crypto should 100% invest in a trezor because not only is their product quality, but their employees are class acts as well. Visit their website to check it out.

ORIGINAL POST:
About 6 weeks ago, I had a house fire. It consumed everything. I did my best to fight it, and when I failed at that, woke my friend up who was staying in a guest room, then gave my all for about 15 minutes to find my cats in the blaze. Ultimately got dragged away by the FD and taken to the hospital. I didn't even think about my bitcoin, as honestly, my cats were all I cared about.
3 weeks earlier, I realized I had a stupid amount of money sitting in a wallet.dat file on my computer, and that I really really should put it on a hardware wallet. So I did. I bought a trezor, loaded it up with my BTC and most other coins I had, and put it in a fire safe:
https://imgur.com/a/DbU9V
Here it is. Thanks Trezor. Your product is amazing. The house burned to the foundation, and the firesafe was externally destroyed, but despite the external appearance, inside was a toasted piece of paper with my seed words and this little guy. He was cooked from the heat, and sopping wet from the flood of water they poured on the house (nearest hydrant was a mile away and so it took an hour to start fighting it).
On that day I lost literally everything. Everything I have ever owned in 33 years of life, and my cats. Since that time I've been emotionally devastated, and I'm working really hard on recovering from that. But because of listening to advice on this sub, I had a trezor in a fire safe. I didn't lose anything but some byteball/pivx/dash I had on my desktop computer I forgot to backup. 95% of my holdings since 2012 remain.
Thank you /Bitcoin and thank you to SatoshiLabs, the makers of Trezor. That little guy is tough as hell. I dont think its advertised as waterproof but I pulled it from an immersed box sopping wet. I let it dry and here is how it looked after when it worked. I now have two cloned trezors in different locations and a safety deposit box with my seed. Saving my bitcoin and this price rise has allowed us to pay for pretty much everything we need since the event happened.
Please, do not offer any donations to me, I'm fine. If you want to support anything, support the Ferndale Cat Shelter or any local cat shelter in your area. I'm the president of the charity. We take care of Detroit Strays. My cats had Guinness World Records and did charity events to raise funds for them. Now that they are gone, we lost that revenue stream for the charity. We accept bitcoin locally at the catfe for donations, adoptions and coffee but I won’t post that info here.
You'll know when you're there as our old address started with 1Catfe and our new address starts with 1CatCafe =) Took ages to offline hash that one out!
Anyways, that's the story, thanks again /Bitcoin, you made the worst day of my life less terrible.
Edit: The Fireproof safe was literally a 40 dollar Walmart special. Would only recommend getting water and fire proof in the future as some medicine I had in there was destroyed due to getting wet

The International 2018 in Vancouver FAQ (Updated!)

Hey there again, you punks.
So with a tip coming from some of the moderators on the board, I've decided just to quickly update this FAQ that I wrote a few months back since TI is next week and I'm sure many of you still have a ton of questions. I've gotten some more information that I can pass down to you in regards to Vancouver but also now TI as well, including updated marijuana laws and beer recommendations.
Two quick notes:

VANCOUVER WEATHER

This summer has been an extremely hot season in Vancouver (at least in Vancouverite standards). Like anyone who attended in Seattle last year, there is noticeable smoke in the air in the city due to the fires all over the Pacific North West. If you have breathing issues or health related problems do to particles in the air, be advised that there is currently an Air Quality Advisory in effect so act accordingly. Wind/Rain will most likely clear up any issues going into next week, but just a heads up in case new fires flare up or we aren't blessed with some light rain. Forecast is looking to be sunny through midweek and the finals, with an average of about 23-25C.

THE PACIFIC NATIONAL EXHIBITION IS OPEN!

A staple for Vancouver residents since 1910, the PNE will be open from August 18th-September 3rd (closed on August 20th & 27th). If you're looking to do something after a midweek day, the PNE is the perfect place to go checkout for a fun night out filled with events, concerts, beer gardens, crazy carny food, rides, maybe BSJ, shopping and a lot more. This article will tell you everything you need to know about the PNE, how to get there and what's going on.
ALSO BOYZ II MEN AUGUST 18TH GET HYPED.

PLACES TO STAY

Yes, but it's not exactly regulated by AirBnB. Feel free to stay at one through AirBnB but know that it might be a little tricky to deal with issues if they come up with your rental. Also while you're at it, check out VRBO.
The general piece of advice you'll get from any local about where to stay for TI is going to be anywhere that's on the Skytrain Expo Line (the line in dark blue). The Expo Line will take you to Stadium-Chinatown station, which is where Rogers Arena is 30 seconds away. As in Seattle, the closer to downtown you are, the more expensive it is to stay.
Unlike Seattle Center, there aren't very many budget hotels left, if at all in the Downtown core. The cheaper hostels are available, though fair warning, many of them are placed on Granville Street, which is a place that many Vancouverites will tell you to avoid while you're here (Though I have never stayed at a hostel on Granville, if anyone has an experience, feel free to share). Check out the Ramada Inn and the Days Inn near Waterfront for some cheaper-ish options.
In my mind, there are two places that I would keep a look-out for avoiding while you visit Vancity.
  1. Granville Street. During the day time it's normally fine, filled with some cool shops (Golden Age Collectibles, The Rock Shop, Movieland Arcade) but it's packed to the absolute max with dumbasses at night due to the amount of night clubs. There's police around every weeknight, but since you're in Vancouver for a good time, head towards Gastown, Chinatown or Main Street for places to party.
  2. Downtown East Side. If you've researched anything about Vancouver, you'll know that this area as where a large portion of the cities homeless reside. There is rampant drug use, poverty and sex work in this neighborhood, focused mainly between 5-10 blocks in the area of Main/Hastings. That being said, the community is an especially strong one, with fantastic human beings supporting the less fortunate. Though there isn't too much danger in terms of being robbed, you might want to just avoid the area at night. Be respectful to the people of this community and you'll have no problems.

TRANSIT

Sadly, no there isn't. We know, it absolutely sucks and everyone in Vancouver is aware. Your options are public transit or a taxi.
Super shitty if you don't like paying for parking. If you can, park outside of the Downtown core near a Skytrain and then head over to the Arena. Commercial Drive is pretty good for this if you can find certain spots. Tinseltown as well if you buy a movie ticket on non-event days.
If you've ever been to any major city, you'll notice that Vancouver shares the same load-up card/tap system that places like London share. It's called Compass Card and it's fairly easy to use. Just load up money onto the card, tap it when you enter and tap when you leave. It'll do all the calculations for you. Note that certain zones will cost more just due to how far you're traveling.
Yes it does! Car2Go and Evo are two of Vancouver's most popular car share services. Hot tip would be to register before you head over to Vancouver and it'll help mitigate the fact that UbeLyft aren't in Vancouver just yet. Just drive safely.
The easiest way to get to downtown from YVR, if you aren't getting picked up/taking a taxi is to take the Canada Line. It will take you directly to Waterfront station, from there you can take multiple buses, the Expo Line (the main line that will take you to Rogers Arena) or the Seabus (going to North VancouveLonsdale).

ALCOHOL

19 years old.
Vancouver has an exploding craft beer culture and you'll be happy to find that the variety of different beers/ciders to drink is absolutely massive, probably to the point of being intimidating.
Here are some of my favorite breweries and the beers that you should look out for when you're at the liquor store/pub:
Twin Sails Brewing
Dat Juice Pale Ale
Two Straws MilkShake IPA
Short Pants Mosaic IPA
Brassneck Brewing
Changeling Sour
Passive Aggressive IPA
Bjorn Again Farmhouse Ale
Steel & Oak
Changeling Sour
Passive Agressive IPA
Bjorn Again Farmhouse Ale
Bomber Brewing
Bomber Parklife Passionfruit Ale
Bomber Pilsner
Bomber Snow White IPA
Yes. First, there isn't any drinking in public if you already didn't know. Second, you must have TWO pieces of ID on you whenever you go to buy drinks in case you're asked for your ID. First piece must be photo ID, the second piece must be something with your name on it (in order for bartenders/servers to validate the first piece). I see a lot of tourists thrown off by this, so just know that Vancouver's liquor laws are much more strict than other places.
I've heard from a few Vancouver residents that this isn't exactly enforced harshly, but just to note that it is an actual law. Piece of mind.
%.05. There will be a ton of pubcrawls and side events going on for people that are attending TI and I'm sure that you'll be blasted one night or another. Please don't drink and drive. If you need a cab, here are the numbers you can contact in order to grab a taxi from downtown.
Yellow Cab: (604) 681-1111
Black Top Cab: (604) 731-1111
MacLure's Cabs: (604) 831-1111
Also, a note for people from outside of Vancouver: the cab drivers in this city are notorious for being hard to deal with at times. Broken debit machines, cash up front, not providing receipts. Use your common sense to get you through pushy cabbies. If they have a broken debit machine and they are still driving, kindly reject them and give your business to another cabbie that will. UbeLyft will be here soon and karma will bite them back.
If at anytime you are in an emergency and don't know what to do, please DM me and I will provide my contact info.

FOOD

Vancouver is a glutenous paradise of places to eat. Instead of giving you specific places to go eat, here are some links that you might find helpful in terms of recommendations:
Meowjin's Guide to TI8
The 38 Essential Vancouver Restaurants
It's To Die For List
This is not confirmed at the moment, but if the rules were anything like Seattle, you will be able to bring outside food into the arena. You are not permitted to bring liquids into the venue. You'll have to dump out your water bottle and refill it once inside. Rogers Arena might have different policies, but thankfully the venue has twice the amount of food stalls including a much more varied selection.
Everyone from Vancouver attending will hate me, but this is going to be one of the hottest tips I can give you: there is a Costco food court DIRECTLY across the street on the lower level of Rogers Arena that DOES NOT require a membership in order to buy food. It is the only Costco food court in Canada that doesn't need a membership to eat there. Hot dogs, poutine, pizza, soft drinks, ice cream and it's all lovingly Costco cheap. Enjoy!

MONEY

Visa/Mastercard are widely accepted everywhere. Cards such as American Express/Discover are also accepted most places, though a few places might reject them for whatever reason (higher charge rates, issues with their machines etc..) Best case would be to make sure you have a Visa/Mastercard with you at all times as a back-up in case you run into any issues. Most places in Vancouver also allow you to use Android/Apple Pay now as well. No bitcoin though.
Well, that's entirely up to you. If you're staying the full week, a few hundred dollars in spare Canadian currency won't hurt you, especially if majority of your spending is going to be on plastic. There's going to be the Secret Shop, but that'll be done through online ordering and not cash payments. Just don't come with nothing. Worst case, always have at least $30-$40 cash on you just in case you run into a bind. It's really entirely up to you and how you plan on spending your time here. Do note that because of the low Canadian dollar, don't be surprised if the price of certain things is higher than usual.
By far it would be the Vancouver Bullion & Currency Exchange due to their lower exchange rates. Banks will more than likely charge you higher rates than the VBCE.

ETIQUETTE

Due to the amount of fires that have started in the Pacific North West the past month or so, please do not throw your cigarette/joint butts into the street, sidewalk, bushes or wherever that isn't a proper garbage. You'll get a ton of dirty looks by locals if you do otherwise.
Canadians are known to be rather polite, we'll answer questions for you or guide you in the right direction (as long as we aren't in a huge rush). As long as you're respectful of the people around you, take care of your hygiene, don't spit on the ground, talk over people in conversation or just avoiding being a total dick, you'll be fine. Though Vancouver is a somewhat socially cold city, that's mainly in dating circles. Get some new Bumble photos up!
Most places won't have the tip included in your bill. It's common courtesy to tip between %10-%15 of your final bill if you enjoyed your meal/drink/service. Feel free to go higher if you had a really excellent time. Some places do include the tip in the bill, but will have it noted usually at the bottom of the menu.
A few. Remove your backpack when you're boarding a bus/SkyTrain in order to create more space for the people around you. Hygiene again is a big one. Remember to fill your Compass card and check your remaining balance at least once a day in case you're transiting a lot. If you see elderly/disabled/parents with strollers attempt to come on board, the polite thing to do would be to offer your seat etc..
Don't worry at all! Vancouver is an extremely multicultural city and the residents here are used to hearing many different languages daily. Best bet is if you struggle communicating with anyone for any reason, download the Google Translate app and use it to answer questions you might have in a discussion.
Use common sense. Most players/talent would be more than willing to sign an autograph or pose for a photo with you. But also be aware that much of the on-screen talent (Slacks, Kaci, panel members) will often have to be running from segment to segment, taking in matches and so on. If they seem to have a minute, ask nicely, thank them for their time and cross one off of the bucket list.
Don't throw things at Slacks.

THE ARENA

No update on this. Rogers Arena is mainly a concrete concourse, surrounded by a viaduct and multiple lower roads. Unlike Seattle Center (which had multiple fields and smaller available venues), the only place large enough outside the Arena that could hold a large crowd with a big screen would most likely be the "main" entrance through Expo Blvd/Pat Quinn Way. There are a few other options in the area, but we're going to have to wait to see how creative Valve is with the space around the Arena. Perhaps they rent out the adjacent parking lots?
No update on this also, but again, there's a lack of outdoor space beyond the concrete concourse. Sportsbar Live will be open, which also gives a view of inside the Arena while you're eating/drinking. But again, it's indoors.
From what I remember from Canucks games, yes, there are stations where you can plug your phone in to charge. But don't be surprised if a company like NVIDIA pops up a charging station outside much like in Seattle.
18,630.
One of the more obvious differences that most people will find from Key Arena to Rogers Arena, is that unlike Key Arena, Rogers doesn't have an open space concept between levels. Meaning, you won't be able to just look up to the third floor and see players hanging out like you normally would. This year, they most likely will be held in the boxes above or in the dressing rooms in the lower levels. Look for autograph times scheduled throughout the week to see your favorite players.
The only thing right now is a Vancouver Whitecaps (MLS) game on August 18th and a BC Lions (CFL) on the 25th. So if you really feel inclined, now you know.

WEED

When: On October 17th, weed will officially be legalized in British Columbia and most parts of Canada.
How: Normally you need a medicinal prescription to purchase marijuana legally. Though, because of the soon to be legalization coming up in a few months, most dispensaries will most likely write you a prescription if you tell them a valid medical reason for the marijuana (Trouble sleeping, chronic joint pain, back pain, headaches, trouble eating etc.). My friends who smoke themselves told me that hot tip, so do with it what you will. Please DO NOT buy weed from a source that isn't verified by another trusted person or a licensed dispensary. You never know what your weed could be laced with.
Where: Here are some dispensaries located close to Rogers Arena.
Bloom Medical Dispensary
The Dub Dispensary
The Medical Cannibis Dispensary
You can't smoke anywhere that frequents children, even if there aren't kids around. So no beaches, public parks, playgrounds etc..
So just, anywhere that's away from people that don't want to partake essentially.

TICKETS

If you weren't able to buy tickets from Ticket Master, you have a few options.
Post in the TI8 Vancouver Subreddit and ask if anyone has a spare ticket.
Buying tickets from scalpers in front of Rogers Arena is fairly easy and shouldn't be difficult if you understand the basics of haggling.
  1. Know what you're comfortable paying and stick to it. Always remember that number.
  2. Be prepared to just walk away. The longer you stay negotiating, the more you show the scalper how important it is for you to buy the tickets. Play the long game.
  3. The less you talk, the less information you give the scalper. If he says he's got a Midweek ticket for $300, shrug and say no thanks.
  4. Have money in your hand/wallet when you're trying to buy tickets. When they see that the cash is right there, they'll be more inclined to just make the deal and move onto the next one.
You will most likely miss the opening ceremonies, but after that the prices for Midweek tickets will normalize and scalpers will want to just get rid of their tickets at a lesser price.
The advantage you have in this instance is that Vancouver, outside of the LoL tournament at Pacific Colosseum, doesn't have much experience with esports tournaments. So scalpers themselves won't have the same level of patience. The longer you wait to buy your tickets from them, the cheaper you can get them for. Only downside is that you'll be missing games.
The other thing you can do is literally just walk around the outside of the Arena and spot non-scalpers with extra tickets. There are always people who buy extra tickets and are just wanting to get their money back (friends flake on them, they couldn't flip them like they thought).
DO NOT panic and end up buying an overpriced ticket from StubHub, Craigslist or wherever. Tickets will be available, you just have to keep your cool.
The box office at Rogers Arena is located at the bottom of the venue on Expo/Pat Quinn Way at the Toyota Ticket Center. You can pick up your tickets between these times:
Mon, August 20th: 7AM - 9PM
Tue, August 21th: 8AM - 9PM
Wed, August 22nd: 8AM - 9PM
Thu, August 23rd: 8AM - 9PM
Fri, August 24th: 8AM - 9PM
Not sure about the box office times for the Finals. Will update that when I know.

FIRST TIME ATTENDING TI

So first off, understand that EVERYONE there is going for the same reason you are, DOTA. Don't be afraid to go up to people, say hello and start conversations. If they shrug you off, fuck them, they don't deserve your brilliance. Enjoy yourself. Worst case, just create a thread on DOTA saying that you want to go shotgun a few beers. My first TI was pretty much by myself, but the combination of a beer + a garden really did wonders.
Simply put, don't worry as much as your mind is telling you to worry. All the talent (casters/players) are incredibly friendly and are pretty much the same as us, just super stoked to be there. But do give them space if they're working or running around to the next thing.
During TI, after every First Blood in a match, there are potential drops given to in arena attendee's who have registered their badge with their Steam ID. There will be a Steam Link kiosk/section OUTSIDE of Rogers Arena, so look out for it. You must have tapped into the Arena in order to be eligible for those drops.
The link to register your badge to be eligible for these drops will be on the back of your badge when you receive it.
Try to pack as lightly and efficiently as possible. My two main staples during the last two TI's were a water bottle (usually given out in a goody bag for midweek + finals ticket holders) and a portable battery pack for my phone. Also know that you might buy things from the Secret Shop, do some shopping downtown and the last thing you want to do is carry that stuff around with you all day. Though consider bringing a sweater for inside the Arena, as Rogers is a fairly cold one.
HOT TIP
Try checking with bell boys/concierge at any hotels if they can possibly check in some of your bags for you. I tried this at TI7 and was surprised how chill they were. I left them a $5 tip for taking my bags and was free for the rest of the day.
Avoid the Secret Shop on the first day or else you'll just spend the entire day waiting in line. Midweek the shop lines will be much more reasonable.

MISC

Well formatted thread to get you started.
Also a well-detailed Google Map of venues/places that should interest people attending TI for places all across Vancouver
Depending on your situation, here are numbers for emergencies in British Columbia.
Ambulance, fire, police: 911
Poison Control: Lower Mainland: 604-682-5050 Toll-free: 1-800-567-8911
Healthlink BC: 811 Deaf or Hearing Impaired: 711
Crisis Intervention & Suicide Prevention: Call 1-800-SUICIDE (1-800-784-2433) if you are considering suicide or are concerned about someone who may be.
Mental health support: Call 310-6789 (no need to dial area code) for emotional support, information and resources specific to mental health.
That is Roger Neilson, former Vancouver Canucks head coach and the inventor of towel power. Please treat it nicely!
Right here.
How sweet of you to ask! That would be Lush by Snail Mail.
Please, if you feel like you need to ask any questions, or there should be things added to this FAQ, post here or DM me. There are obviously some things that no one knows right now in regards to potential additions or subtractions from moving the event from Key Arena to Rogers. But I'll try my best to keep this thing updated if people bookmark it for future use.
Enjoy planning your trip to TI!

Do Bitcoins just disappear?

So I am having a major problem, I backed up my wallet on an external drive because my old hard disk dive was starting to freeze up on me and so I had no choice but to buy a new one. I read online all I had to do was re-download the Bitcoin app on my new hard drive and copy over my bitcoin files from my old computer. But to my horror almost a day and a half later after my computer finished syncing up with the bitcoin network I saw only zeros in my Wallet. To be fair I only had like $100 dollars in there but the thing is I worked over the last year and a half going from website to website colleting whatever payouts and even setting up a coinbase account to make small purchases when I had some extra cash. But now its all gone, what did I do wrong?

(Upvote to the top) > SOLUTION FOR ZCLASSIC Eleos Wallet: "Wallet daemon can not be run. Check if daemon does not already run"

So I noticed a lot of people recently (including myself) are experiencing the error "Wallet daemon can not be run. Check if daemon does not already run" when trying to open up their ZCL Eleos wallet, and people are unable to access their funds or cannot export their private keys as well. A solution to this is now official (thanks to JBrutWhat from the BTCP team for helping me out on this.) Note: Post is being edited as more info becomes available to me.
This solution also works for users who are on the ZClassic Swing wallet experiencing the error "A general unexpected critical error has occurred: error: Couldn't connect to server, see the console output for more detailed error information!."
Eleos Wallet Troubleshooting section
ZClassic Electrum Wallet
  1. Create a new standard wallet and restore the 2FA wallet using your "seed" codes. DO NOT password protect this wallet.
  2. Disable the 2FA feature when presented with the option.
  3. Navigate to C:/Users/YOUR-NAME/AppData/Roaming/Electrum-zcl/wallets. Open the new standard wallet file with Notepad.
  4. You will need to gather the 2 private keys and one public key. To find this easily, press “CTRL+F” and search for “xprv”. Copy the 2 “xprv” values as well as the last “xpub” value. You will need these in a later step.
  5. Create a new “Multi-signature wallet”. Select “From 3 co-signers” on the first slider. Select “Require 2 signatures” on the second slider.
  6. To add the first co-signer, click “Use public or private keys”. Enter the first xprv key in this box.
  7. Add the second co-signer via a private key also.
  8. Add the third co-signer with the public key. Complete the set-up.
  9. Your wallet funds now have the ability to be sent from the multi-signature wallet.
For Users who were already using the Electrum wallet beforehand, you can go to file > new/restore wallet > next > import zclassic private keys and input the private key you obtained from the walletaid tool, and it should import the wallet into the electrum wallet. Then from there, go to file > backup wallet and export a copy of the wallet.dat file onto an offline USB.
Reminder: Backup and delete the private keys file from your desktop pc/hard drive, move it into an offline USB for safekeeping. Do not leave it on an online device.

Import for free clams? But...

... my wallets aren't in wallet.dat format, they got imported in to Multibit. Any suggestions?

Did I steal $500,000...?

I posted this elsewhere, and will condense the interesting question into one paragraph. The original post is below that if you're interested in more context. And there's a tl;dr at the very bottom, but this paragraph here is a good summary:
In summary, I acquired a long-lost computer from a cousin who died 8 years ago. Nobody was aware that there were Bitcoins on that machine. Who do those coins belong to? If someone gives you a book and there's a $100 bill it, there's a good argument to be made the $100 is yours. If the book contains login info to a bank account with $100, taking that money is stealing. But where do these bitcoins really live and who possesses them... especially if nobody ever knew they existed?
---
Original Post.
I cleaned out an old account to post this... consider it a throwaway for obvious reasons.
It’s a long story, but it needs complete context…
I’m an only child. So was my cousin… my dad’s sister son, also an only child. We were about 3 months apart, and we were close friends.
The families used to get together over the Summers… they lived about 8 hours away, but there was a lake near their place, so we’d visit and go there for a few weeks every Summer holiday. The best memories of my life, without question. And also the worst, because in the Summer of 2011, he drowned. He was 15.
Nobody knows what happened. Horsing around on a raft on the lake, lots of kids and adults around, and suddenly, hey, where’s Bobby. He’s here somewhere. Looked around, nowhere to be found, maybe he swam back to shore, he’ll show up, he must be kidding, hey Bobby this isn’t funny, where the hell are you…. annoyance growing to concern growing to panic, cops called, everyone searching… and the water was pretty deep and murky, but someone deep diving (20 feet) not too far from the raft found him.
And we never really found the cause. There was no evidence he hit his head or any unusual markings or anything. He just drowned, and to say it was devastating would be a big understatement. My aunt and uncle have never been the same, and for years, they kept his room intact, as if Bobby might suddenly show up. Apparently my aunt changed the bedsheets every so often, as well as dusting and whatever else.
Obviously, the Summers at the lake ended… in fact, I didn’t see my aunt and uncle for about 5 years. My parents went and visited a few times between 2011 and 2016, but without me.
On one of those trips, I guess they convinced my aunt to start letting go… and my parents came back with a bunch of stuff that had belonged to Bobby that they thought I’d want. I used his baseball glove for a bit after mine wore out, but it felt wrong. The rest of the stuff sat untouched in our garage for years.
Last year, I had a 3.5” floppy that I wanted to get a file off… and was scratching my head because I had no PC with floppy drive. Then I remembered Bobby’s old PC had a drive… the one sitting in our garage. I’d never bothered hooking it up at home. It was older and crappier than mine, and I knew it was nothing but a bunch of games which were already 5 years out of date when the computer arrived.
But it had that drive, and if I could boot that machine, great… so I hooked it all up and turned it on and yay, it worked. I hadn’t really figured out how I was going to retrieve what I needed. I initially just wanted to see if it’d work, and it did, but the computer wasn’t even hooked up to the internet… no need. I found what I needed and screen-shot everything I needed off the floppy, but before turning it off and packing it up, I started poking around a bit to see what might be there.
The short answer is nothing exciting, except… a Bitcoin wallet. Not with a million coins or anything, and at the time, pretty much worthless. From what I can tell, they weren’t worth much back then. I really have no idea where they actually came from. I suspect from the transaction log on the wallet that he downloaded the client, ran it for a while, got bored with it eventually and forgot about it and its measly roughly 47 bitcoins. There wasn’t much else except a short note with public key/private key and a recovery phrase and a backed up wallet.dat that I actually never managed to get into, but I was afraid to connect that machine to the internet in case those coins somehow vanished… it took me a while to educate myself about it, but long story short, those bitcoins now live on my phone, password protected and 2FA protected and wallet backed up and from what I can tell, there has never been an outgoing transaction from this wallet.
So, here we are. Roughly half a million dollars. Who does it belong to? Legally, I’ve brought it up theoretically with people and it’s always an interesting discussion. Is it like finding a physical wallet with cash in it, and no ID? Is it like finding bank log-in info and swiping the cash in the account? They gave me the computer; isn’t what’s on it mine? If someone gives me a book from a used bookstore and there’s a $1 bill in it, it’s mine, right? What if it’s $100? Still mine? What if it’s $100,000?
That’s a technical, legal discussion. Feel free to weigh in. The other is the moral/ethical discussion. Is it my aunt/unlce’s? Half of it? Some of it? Nobody in this equation is in debt or lacking money. All happy middle class folk… for whom this would all be a lot of money.
At present, I’m in school not racking up any debt because my parents have agreed to pay for my education as long as I take it seriously, which I am.
So… this all just sits there, but I bring this up now because I’d be lying if I said I’d never felt guilty about it. Of course, I haven’t absconded with it, and there’s all sorts of plausible explanations why only now I mentioned it… like, hey, I just hooked up Bobby’s computer and guess what… whatever. I bring it up now because we will be with my aunt and uncle this coming week, and maybe it’s time to say something. Or not. Or what.
Feels good to write about this because I’ve never mentioned it to anyone, but at some point, this needs to see the light of day.
TL;DR found a stash of bitcoins on my dead cousin's computer and haven't told anyone about it (yet?)
EDIT: Not sure it's relevant, but the bot told me to update my location... Canada.

[PSA] Dogecoin Wallet version 1.4 released. You must update.

WARNING: DO NOT send your wallet.dat file or dogecoin folder to anyone. There have been reports of people offering to help others by asking them to send their files to them so they can help. DO NOT do this. Scam attempt picture
Always encrypt your wallet! I can't express this enough. You should use a strong password longer than 15 characters. This password should contain numbers, symbols, and some capitalization! There is no need to have your wallet open 24 hours a day. Open it only when you need it. See - 'Getting Started' on the side bar.
This entire post has been written to be as close to ELI5 (Explain it like I'm 5) as possible - By request! If anyone wants to add/fix/correct anything in this message, please send a message to the mods <<-- Click blue text.
All blue text in this post can be clicked on. The blue text is a link to a picture, site or download file.
A very important message/reminder below.
25 Jan 1.5 pre-releases have started.
http://www.reddit.com/dogecoin/comments/1uhpwf/dogecoin_for_mac_14_topic_thread/
OLD VERSIONS The 1.4 update for the dogecoin wallet has been released. This update addresses the block chain error that occurred. This update is mandatory meaning you have to do this update. Also further down the page you can read up about the block chain. You MUST make sure you're on the correct block chain and the old block chain has been removed.
For a Windows computer the version must be 1.4. - 1.4.1 just released! See below
For a Apple Mac Computer the version must be 1.4
Download links:
[Windows Download Link](https://github.com/dogecoin/dogecoin/releases/download/1.4/dogecoin-qt-v14-Win.zip) <<--Click to start download
Windows Download Link 1.4.1 UPDATED 19JAN
Mac Download Link <<--Click to start download
Mac users can join this thread if there are any problems
Android (phone): Please see This post
To update, simply download the new version from the download link above. Open the downloaded file and extract the contents of the downloaded file into any new folder or location on your computer. If you put the files into a folder you can name the folder anything you want but make sure you remember that this is the latest version of the software.
You don't have to remove your folder containing the old version of the wallet. You can place it in a folder called 'Old versions of dogecoin wallet' if you like.
Now you can click on the Dogecoin icon contained in the new folder to open your version 1.4 wallet.
What happens if I get an error when I open the new wallet?
An error was reported called "11DbException"
If this happens Download this file and place it in the same folder as your updated wallet. Open the file you just downloaded called "Dogecoin OPEN' and wait. This might take 2 or 3 minutes.
Also jtlarousse has found a solution that worked on Windows. Please follow carefully and make backups before starting.
Reebzy might have found a solution for Apple Mac
Blockchain fork 101: The block chain is a ledger or document created containing every transaction that has ever happened. This file can be quite large. Bitcoins ledger is over 15GB. At some point this document/ledger split into two separate documents known as a fork.
How do I know if I am on the right block chain?
Go to your newly updated dogecoin wallet and open it. Click on Help>>Debug next Observe the current block number
*Note the example numbers in the pictures might be out of date by the time you read them
Now go over to http://dogechain.info/chain/Dogecoin . This website is the official Dogecoin blockchain website. Check the block number they're reporting
The number you found in your wallet and the number reported on the website should close. There might be a difference of 100 blocks depending on when you last refreshed your wallet or how long it took for you to get from one step to the next step in this guide and if the dogechain website is lagging.
I'M NOT ON THE CORRECT BLOCK CHAIN
My numbers are very different. How do I get back onto the right block chain?
IMPORTANT
For windows:
1)Close down the Dogecoin wallet client.
2)Go to your data folder: C:\Users[your windows log-in name]\AppData\Roaming\DogeCoin
3)Delete the Dogecoin.conf file. Do not delete the wallet.dat file!
4)Download this update file and place it into the Dogecoin folder where the other file was deleted.
For Apple Mac:
1)Close down the Dogecoin wallet client.
2)Go to your data folder: ~/Libarary/Application Support/Dogecoin
3)Delete the Dogecoin.conf file. Do not delete the wallet.dat file!
4)Download this update file and place it into the Dogecoin folder where the other file was deleted.
Next visit this post by Netcodepool for instructions on how to manually download the correct block chain and install it.
Much Thanks. 
Edit: Some posts were removed from this thread. To limit confusion.
Check this post for details about mining pools that were/are using the wrong fork.
Did you send coins only to find out you're on the wrong chain? See this post to get them back
An Apple Mac support thread has been made by voidref (The mac developer). If you're having troubles please see this thread
Some shibes have reported their wallets wont sync. Please check to make sure your firewall, antivirus, malware scanner or similar programs are not blocking it the wallet. You can add rules to these programs to allow the wallet to make contact with the internet. It's not advised but possible to also disable the software for a short amount of time. Don't forget to enable the software again afterwards.
Is your wallet crashing? Try this helpful tip from gandhikahn or if you're using windows try the 1.4.1 update above.

Lost Bitcoin Address, Bitcore Core client

Hello, I'm in a state of panic right now. I had recently decided to transfer my bitcoin from an online wallet (Blockchain.info) into a local wallet(Bitcoin Core).
I had send bitcoin to one of the pre-generated receiving addresses, prior to syncing up with the block chain. After the client had finally finished, the receiving address was no longer listed.
I can view the transaction and the address on blockchain.info, and tried to use dumpprivkey on in using the debug window, but it said the private key for the address isn't known.
I'm not sure if this is relevant, but during the block chain syncing process, my SSD ran out of space, so I followed a tutorial to use my secondary HDD which has a larger capacity. The instructions told me to paste "-datadir=F:" into the target field of the program.
Please help.

Bitcoin stuck on broken wallet

I keep my bitcoin on a wallet on my Linux partition; recently, it failed to synchronize. I've tried sending a small test transaction to a wallet I have on my Windows partition; but the transaction never arrived.
Is there any way to access my bitcoin from my Windows wallet, without needing to send it over in the form of a transaction?

Zcash4win & Zcash4mac MEGATHREAD

This thread is for users to find information that is spread across many threads since zcash4win and zcash4mac are now depreciated.
What happened:
David Mercer the developer who worked on zcash4win and zcash4mac has decided stop allowing downloads of these (which are stuck on old versions) so it doesn't confuse new users since they not up-to-date. David is not part of Zcash Company and his software is open source. The only "Official" Zcash software is the Linux version.
Why
Rather than continue to update the zcash4win and zcash4mac code he has decided to create new wallet/node software from the ground up so it will be a better codebase/GUI and easier to update for the future. The new version will be called "winzec" and available at winzec.com when it is done.
What does this mean for zcash4win and zcash4mac users?
If you are currently running zcash4win or zcash4mac you don't need to do anything. The zcash4win and zcash4mac are just not available to download, they will continue to work until the Hard Fork expected in a few months.
Are the funds I have in zcash4win or zcash4mac lost?
No, remember the way all Blockchains like Zcash and Bitcoin work is that coins are on the Blockchain at all times. Your wallet has the Public and Private keys that allow you to spend from the addresses you control.
Help my wallet won't start!
Since the zcash4win version is version 1.0.12 (and the latest version is 1.0.15) you need to add disabledeprecation=1.0.12 to the configuration file as explained in this thread: https://forum.z.cash/t/required-config-change-for-zcash4win-1-0-12/26632
There is a Video of how to do this Here: https://youtu.be/VT06Nh6TTzw
This will keep the node from auto-depreciation and allow you to still use it until a the new version comes out or the Hard Fork when you will need to switch wallets.
If you do the above steps and it still won't sync you may have to reindex your chain:
Open a Command window and try:
C:\Program Files\zcash4win\app\zcashd.exe -reindex -daemon=0
NOTE: The above line is just an example and will need to be tweaked depending on your computers users/app location/etc..
If you are not familiar with how to run something from a Command line please see this tutorial: https://m.wikihow.com/Run-a-Program-on-Command-Prompt
What if I want to switch wallets?
To switch wallets you first need to determine if you want to use or have funds in a private address.
If you don't have funds in a private address and don't want to use private addresses then you can transfer your funds to many other wallets like Jaxx or a hardware wallet like a Ledger Nano.
I have a list of wallets here: https://www.zcashcommunity.com/wallets/
If you do have funds in a private address and don't want to send them to a transparent address read on:
Step 1 is setting up a new full node. You can install the Zcash Official Linux Client via this guide: https://github.com/zcash/zcash/wiki/1.0-User-Guide
There are several Videos on how install Zcash on Linux here:
https://youtu.be/5ahQZZYcntQ https://youtu.be/9-P7IHC7d-o https://youtu.be/noiPWhPT6sk
I have an very old written step-by-step tutorial about how to set up a VM and install Linux & Zcash here: https://minezcash.com/how-to-mine-zcash-part1/ (just ignore the last "mining steps)
Step 2 Is once you have a new Node running you have two choices: You can generate a new address to send the funds to the new wallet or transfer the wallet.dat file to the new node.
Instructions to get a backup of your wallet from zcash4win are here:
https://youtu.be/JGtpUnHTf2w
You can use that wallet.dat to restore your funds to any full node wallet Linux Windows or Mac.
The best part about running a the official client is that you can update as soon as an update is available directly from the Zcash developers! No more waiting for third party developers to push an update.
While you are here, take a second to backup your wallet.dat file to somewhere safe, preferably offline or on a separate computeUSB so in case of disaster you won't lose everything.
Please feel free to post questions in this thread, new threads on this subject will be closed and re-directed to this thread.

[Help] [Question] I had to erase MBP and couldn't restore from time machine. Now I need help retrieving my old wallet info?

As stated I had problems with my MBP and had to do a clean restore. I then couldn't restore it from my backup on my time machine but instead had to pull the individual files from the backup. I need help finding a way to retrieve my old wallet and I believe I have a .dat backup? I do have the Bitcoin-QT wallet and I don't want it to start up and sync till I know how to retrieve my old wallet info. Any help would be greatly appreciated. Also just in case the .dat file isn't any help is there a way to pull it from my time machine backup?
[Edit] I have located the new wallet.dat file and Bitcoin folder and added the Bitcoin-QT Backup.dat file in there but haven't done anything with it yet. I am thinking about going ahead and running the Bitcoin-QT wallet and let it sync and see what happens.
[Edit] (Update) After posting on here and Bitcointalk.org I had enough people come together and had different ideas to figure it all out. So my folder was hidden from plain sight and had to use the command+shift+[G] keys to see my hidden Bitcoin folder. Once I was in that folder I entered into time machine and the same exact folder came up and I went to the last backup before my computer got restored and copied those files and pasted those into the Bitcoin folder created after opening up Bitcoin-QT again to do a fresh sync.
So I deleted the new files and added my old files from my backup and then opened up Bitcoin-QT and it started to process and verify blocks. Once it opened up it had to sync all my data back on and showed my account balance from what I had prior to this whole ordeal. Now I wasn't sure it was going to work so it spent all night reindexing and syncing the blockchain and finally finished this morning. Once it finished I closed the wallet down and reopened it and it came right back to my wallet. So I am thankful for all the help and appreciate the bitcoin community for this. As I am sure everyone knows it can be kind of stressful to have to deal with something like this but luckily there are files and backups that help prevent anyone from losing the wallet completely.
I will now make sure I backup the wallet every month or so if not more often. This is one thing that I believe scares people from using bitcoins because it is easy to lose your wallet/BTC if you don't know what you're doing. I am looking into the Electrum wallet as well to see if I actually like that one. Thanks again for your help.
