Regardless, there's always a trail, if that's hack and OP can still access the account, he can certainly check the transaction history if there is a withdrawal, if none, there's something happening here that involve the exchange itself.
My fault is I don't check my email, that says someone has access on my Account.
Yes, I already do all that. The problem is the hacker has method of accessing my account on HITbtc but he/she can't withdraw the funds because it needs email verification that's the thing that I prove that he/she don't get access on my email. So he/she just dump all my funds. What a cancer in crypto
It is impossible for us to recover our account if it is already in the hand of hacker. The only thing we can do is to report our account to the exchange. And if we recover our funds, withdraw them as fast as it could be. Another thing, be observant on our account and sites we entered so that we can avoid phishing sites that may harm our account.
