Hello Everyone, bit of a odd, embarrassing, question here.

I got some bit coin a while ago, and I plan to hold on to it for a while. I didn't forget that I have it , I just kinda lost touch with the technology. and I am not sure how to access the coins now.

While I don't want to sell it today , I want to make sure I still "have" access to it, and can sell it when I want, or use it to buy stuff.
I stored it on a computer, that I no longer use, but I can still access the files( for now). I might have a wallet address.

The original program I was using required a large download, I think it was like 5 gig at the time, it was the block chain I think.


How do I go about "finding", and regaiing contorll of my coins ( I have some lite coin as well to )  - you can assume I am as noob as it comes.

Links to help guides are also appreciated.
Cheers.

Each block is stacked on top of the previous one. Adding another block to the top makes all lower blocks more difficult to remove: there is more "weight" above each block. A transaction in a block 6 blocks deep (6 confirmations) will be very difficult to remove.

Short version: You probably need Bitcoin Core (now 200 GB), and the file you're looking for is wallet.dat.
Make safe offline backups before doing anything else!

Long version: [overview] Recover Bitcoin from any old storage format.



If the blockchain was 5Gb, then the coins you have got in the wallet will probably buy you a Lambo. Smiley
Judging by his post history:
Mine is : 1QCvEe6xU6Dsh83bxEaEsh8ftGnoqUvgoH
He's looking at at least 2BTC ($7000). And that brings me to the next point: Don't trust any PMs you receive!

Not directly - but what was the value of a single Bitcoin when the blockchain was just 5Gb?

You could scan your whole drive for bitcoin core wallets. (Bitcoin core was one of the very few wallets back in the day, so there is a huge change it's the one you had)

I made this a few months ago : https://bitcointalk.org/index.php?topic=5071775

I bumped it so you/other future people could see it, since this problem seems to be recurring every month.

The latest version also dumps your private keys in a text file wherever it found the wallet, so you can easily import them in a new wallet if you prefer, instead of downloading the full blockchain again / upgrading bitcoin core.

5gig i think you used bitcoincore
download pywallet from https://github.com/jackjack-jj/pywallet, run pywallet.py --dumpwallet ->wallet.txt
wallet.txt will have all your private keys
download electrum from https://electrum.org, import your private keys

FYI, Electrum is another Bitcoin wallet where you don't need to download whole blockchhain. It's good alternative if you don't plan wait few days to download 200GB+ of blockchain.

Few warnings :
1. Make sure you remember the password of your wallet.dat, you can't access your Bitcoin or extract private keys without it
2. Make sure you download Electrum from official website. Verify it's PGP signature if you're paranoid, there are few handy guide such as https://www.linuxbabe.com/security/verify-pgp-signature-software-downloads-linux
3. Never give your wallet.dat files, private key or seed/mnemonic words to anyone

Maybe you should clarify WHAT you have,

1) Is it a wallet.dat file?
2) is it a blockchain.com online wallet login or backup file?
3) Do you have a 12/24 word backup mnemonic phrase?
4) When was the coins purchased and when was the last time you accessed them?

To use your wallet.dat file you place it in an empty directory. Then simply download and install bitcoin core from bitcoincore.org and the first time you run it it'll ask you for the location of the data directory. Point it to the directory with the wallet.dat file. It'll then load your wallet file and start synching the blockchain. The blockchain is some 200GB so if you wish to continue using bitcoin core you will have to wait for it to download and verify all that. It'll take a few days. Note that you don't have to store all 200GB. You can enable disk space usage limits in the software settings (look for the settings option in the menus).  However you will have to download it all.

Alternatively if you want to bail you can go to help > debug window > console and then type "dumpwallet </path/to/dump/file>" to dump your private keys. If you have a password set you may have to do "walletpassphrase <password> 600" first. Then you can open your wallet dump file using a plaintext editor like notepad and sweep your private keys into electrum. Your private keys are the long strings beginning with 5,K, or L.
