The advice and assistance you are getting from knightdk is worth listening to. He's got a pretty good idea what he's talking about and is a helpful person.
As is typical of someone with a paid advertisement in their signature, merelcoin doesn't know what he's talking about. He's saying things that are simply wrong. Listening to him, and following his advice, are likely to make things worse for you.
Before you touch ANYTHING more, the first thing you should do is search your computer for any files named wallet.dat. If you find more than one of them, you should be EXTREMELY careful not to overwrite any of them with each other, and you should IMMEDIATELY create backups of all of them on something that you can remove from your computer (such as a USB connected storage device).
After you originally installed Bitcoin Core, whenever that was, it would have been a GREAT idea to backup your wallet. Since this is real money, and you wouldn't want to risk losing your money from something like a hard-drive crash, you hopefully would have created a backup of the wallet at least once sometime in the past.
So,
- Have you ever created a backup of your wallet in the past?
- If so, do you know where to find that backup?
- Have you searched your entire computer for all copies of wallet.dat yet?
- Have you made backup copies of all the wallet.dat files that you found?
- How many did you find, and what subdirectories (folders) did you find them in?
Hi DannyHamilton, Just a quick question: you say that my advice is completely wrong, and that the OP should in no way follow it... But all i said to him was
1) he should backup his wallet.dat to a secure location
2) he could use this backupped wallet.dat on a second pc, so that when he syncs his clients using the wallet.dat from point 1 he will probably see his coins back (since the wallet.dat from point 1 should contain his private keys)
3) he could also export his private keys and sweep them in an SPV client
I should have added the fact that he should have looked for every wallet.dat on his system to make a backup. But if he'd followed my advice, he wouldn't have touched his core client on his original pc.
The thing is: i sincerely gave this advice while trying to help the OP, could you please teach me a bit, and tell me why my advise was wrong?
I know you've been around a lot longer, and have more technical knowledge than i do, so instead of trying to defend myself, i'd like to know what i did wrong so next time i could give the correct advise if somebody asks for it.
