Hi, Im run in a problem, all my btc from electrums wallet just has gone, how could be possible?? the same problem occur in two wallets of mine, i dont know why, please help!!
The short answer is: anyone who has your private key/seed will be able to spend your Bitcoin, regardless of whether you open your wallet or not. If you can answer ETFbitcoin questions then we might be able to determine how that happened, but there is no way to restore your Bitcoin, ever (unless you want to do a block re-org which is practically impossible).
Seems like you have multiple wallets that got hacked, does anybody else have access to your computer/laptop that you use to manage your Bitcoin?
