Thanks for tips, actually I was wondering why your account was hacked since you did these security measures? If you have somehow identify the reason why your account was hacked and potential loophole of the above strategies that would be worthwhile to share.
Honestly I'm not sure, I cannot recall if I was victim of phishing by making click on some URL posted on the forum. However, I remember using the search engine of btctalk days before being hacked (which asked me to login). Fake site bitcointalk.to I don't think so because I never remember my credentials so password-managers take care of it.
I always use different user names & random passwords on each site, also have several emails for different uses. The only thing that I regret is that my password wasn't that strong (12 characters) and after the 2015 data breach I changed the password by just adding a symbol. Also I should have done the homework of regularly changing all my password on January of this year but I didn't.
Even though, I still blame Admins because it could have been prevented just by being proactive.
