I may give wallet.dat to some members for their check.I hope I can recover wallet.dat with 319 btc
Don't be so crazy to give the file which you think have 319
BTC.
Look at his
red trust before dealing with this guy, he used to offer "recovery" services, and this is no doubt a trick too.
This warning applies here too:
As an aside, it is not safe to use potentially malicious wallet.dat files. Anyone who gets sent a wallet.dat from a third party should take great care in using it. I would not be shocked if it were possible to get arbitrary code execution from a wallet.dat file. If a bad guy found a way to do that the best way to exploit that discovery would be to pose as someone who corrupted their wallet and encourages people to try to 'scam' them by getting a copy of their wallet or help them with a promise of an outsized reward.
