Today I received email letter that someone is tried to login to my C-CEX account. Attempt was from Russian IP address 5.166.80.202. And it's not the first time when somrone is trying to access my account, and as I see, it happens often to other users. I think C-CEX is the only exchange where users face similar issues so often.
I have also got several failed login attempt alert and those are not only from c-cex. May be your email is spreaded all over the internet like mine, so hackers are trying hard to get into our account even without knowing how much we have inside
(I have 0
BTC there).
