Re: Someone had access to my account last month - Please beware!
This guy is a hacker. Please give negative trust to this account. I am the owner of this account and he changed email address signature affiliate code and Bitcoin wallet address today.
The thing is screenshot aren't 100% verifiable to proof of your ownership, you need to sign a messages (but you said the address you used are from exchange) tagging without verifiable proof isn't correct.Now no one will be able to hack my email like legendster without authentication code. 
If the hacker has access of your phone (which the same phone you get the 2FA code) you can still get hacked.
