Do you think it will be fine? What should be next steps then?

As long as you have the wallet.dat, you can recover the private key and thus spend those coins. Instead of downloading the whole blockchain again I suggest you try to restore it to where it was before you deleted it. Not sure how the timemachine works, but thats probably the easiest solution. Restore as much as you can and try to start bitcoin core again. If you can just send the coins to your bc.i wallet.

OP, no you cannot recover it. :-( The new "change" address was only in your Bitcoin-QT wallet, and not in the Blockchain.info wallet. For now, you should probably stick to Blockchain.info or if you want a desktop wallet, something like Electrum. Electrum in particular gives you a set of words you can write down that will always ensure you can recover your money (as long as you use only the addresses it provides you!)

Yea, I have that too, and I also imported the private key into it for BlockChain.info address.

Have a backup of Electrum seed passphrase safe too.

Thanks for reply mate!

That's harsh.. Sorry to hear that. If it's any consolation, we've all lost coins at some point..

And I think you'll find your experience is quite common amongst new Bitcoin users (not using Blockchain.info.. which makes it super simple).. it has a steep and unforgiving learning curve. All the best things in life do Grin

Welcome to the CLUB!

ps If you ran a mac and had a time machine backup, it 'might' be possible.. ?

Oh yes!! I have my Time machine configured!!!.... Cheesy

let me give it a try!... I totally forgot about it. Cheesy

There is a resonable chance you can recover your wallet.dat file. The file is still physical on the drive, until it eventually will be overwritten.
Shut down the computer without further notice, and use another computer to recover the file from your drive.
The more you use your computer the less chance there is for a recovery.

P.S.
Always backup your wallet.dat file, even if just running tests.

I found my whole 'Bitcoin' folder at '~/Library/Application Support/' through time machine. It's about 37 GB. Copying it to 'Downloads' directory. And it includes wallet.dat file Tongue

Do you think it will be fine? What should be next steps then?

Personally I save all my wallets for historical reason. Not really any good reason to delete them.

Thanks for the replies guys.

I was totally frustrated at that moment.

Deleted the Bitcoin-Qt from Applications, and deleted the folder 'Bitcoin' from '~/Library/Application Support/'. And trashed it. Huh

I orignally use Blockchain.info wallet, and was thinking about testing Bitcoin Qt, so imported private key to Bitcoin Qt and used it to send some BTC.

I thought Bitcoin-Qt was compromised, and may be some hacker injected their address in between somehow or something similar happened.

I usually just use BlockChain.info wallet and never had such experience. Sad

Do you think I can still recover the BTC? I think No. If so, that's okay. I learned by lesson then. A hard one of course. Sad

I just sent 0.3 BTC from Bitcoin-Qt wallet. The transaction showed extra 0.17 BTC sent from my account in that same link! I never sent 0.17 BTC to that address!! Don't even know that address!

What the hell just happened!!!..... Sad

Change!

I hope you kept your wallet.dat

Maybe you should take the time to understand what your wallet does before you jump to conclusions based on assumptions.

Change? Yes, change. Think of bitcoins you receive as lumps of gold. You received 0.47838041 BTC in the past as a single lump. Now if you want to spend 0.3 BTC this bigger lump is melted into two smaller ones. One is send to the address you specified and the other one is send back to you as change. How change is handled exactly is different for different wallets. Bitcoin core sends the change to a newly generated[1] address that is part of your wallet.dat. If you enable "coin control" in the options you can see this address by going to the send panel and click "select inputs". You will see it listed with the label (change).

Well... if you still have your wallet.dat. If you deleted everything in a fit of rage you essentially deleted your chance to get the coins back.

[1] its not actually generated at that moment, but in advance and hidden from your sight until its needed.

That was another address in your own wallet. That's called a "change address". When you spend bitcoin, you MUST spend all of an "input", which is money you received elsewhere.

All Bitcoin is is a chain of transactions going from A to B to C all the way back to when the coins were first minted. So when you want to send 0.3 to somebody, what you do is you say to the network "hey look I got 0.47 from this transaction before, and I'd like to use it now". And since you must spend all of it (that's how the protocol works), it sends 0.3 to the person you're sending it to, and the rest back to you (at a different address but one which you still control). Then later, when you want to send 0.1 to somebody, the tx will use that 0.17 and send 0.1 to somebody, and 0.07 back to a new address of yours.

If you still have the file wallet.dat and haven't deleted it, you can recover your 0.17. It's in there.
