I'm starting to make really big worries about bitfinex. I want to say from the very first moment that I am a person who is having a obsesion on security, 2fa and stuff. On fridays I'm trading at least 10-15 btc on bitfinex and now I am worried. There is anyone on this forum who had same problems?
Just migrating to another site which can give you better security such as kraken.
And try to identifying your browser, do you put any change for your browsers such as vpn or something. That means someone is able to log-in into your account because all of your screenshot said the successfully log on to your account.
So, what's happen with your amount?

I really wouldn't use bitfinex. Their Bitcoin price is usually like $50 above most other edchabges which isn't good, and they've been through alot recently. They were hacked, they released some really crappy tokens, and their bank accounts were closed. I'd love to a different exchange asap.
I don't see anything related to the op's problem.
