At least they reopened the account, and they allowed me to withdraw the profit. I'm feeling lucky

You got really lucky frankly speaking. I thought your money was gone for sure. Most victims never see their money again which is why 1xbit spared you for reasons that only they are aware of.
My advice is to learn from this lesson and never return to this scam site ever again since luck won't always be on your side.
I'm not sure if this account is a legit case? or an account being created just to pretend having issue and then pretend to be solved case, he did not even bring any proofs of how the problem happens and resolved , and it is impossible that he does not received same answers from all of the true victim here and the reason for banning is their security find his account cheating lol.
