It doesn't matter how strong or long your password is if you've got a keylogger or reuse the same password or enter it into a phishing site. If you can I'd set up 2-factor on your email address. 2-factor will be coming for this site with the new forum early next year so hopefully that will cut down most of these hacked accounts.
I don't have idea what happanened. I've thinked I use everything carefully but looks like not.
Hacker got acces to my F2pool and Guild account too.... I have luck he was just able to steal 0.44 Btc.
I've changed my e-mail and everything now, made a complete revision on all my accounts.
I'm just sad to loose my Sr. membership here....
