my account was hacked and lost 0.0012 btc.
I dont know who done it but all i have is their waller address?
I dont understand how they done it, seeing how no one else is meant to see my link.
Well, if someone was actually trying to steal from your Bitcoin Minefield account, it would not be too difficult.
It was assumed to be too unlikely that someone would try to steal from it. (As was mentioned before in this thread, there is no real security, just the secret key which is sent to the server unencrypted)
