In theory is it possible to recover BTC sent to Bitfinex BCH wallet?
I know there is recovery options with own wallets, i believe Bitfinex should also have generated wallet seed somewhere
I have tx and all related information.
So does Bitfinex support could help me? ...
You're spot on. In fact Bitfinex support is the only place to go. Bitfinex will have the private key for your BCH deposit address and can 'recover' your BTC by importing the same private key into their BTC wallet. This will involve various 'support levels' (the person answering emails will not have access to any private key) and manual work + busy times at the moment for support staff in cryptoland = it will take some time, but there is hope.
Not sure about Bitfinex... but some exchanges ask for a 'recovery fee' as there is some work involved. Let us know if they ask for something like this, would be interesting.
i posted also on reddit and found that a lot of other users have experienced the same situation, in most cases it is only a matter of time because they are literally inundated by this type of requests
Guess it's a opportunity to take a break from cryptoland until the support is catching up.
Crossing my fingers they will reset your 2FA soon!
