Are you sure it is bitfinex?
I think that's weird because some destination addresses are segwit and some are legacy.
It looks like a legacy address running some kind of script to redirect transfers.
Maybe it is a coinmix?
Thanks mate,
i didn't get it was a mixer, you're probably right
so this is the address used by the mixer and not a personal address, correct?
A guy is asking me to send a payment directly on this address,
how the mixer associate the transaction to his destination address?
i also noticed this address in ANY outgoing transaction

There are coinmixers like bitcloak which allows a user to pay anonymously using it.
You tell the mixer the destination address and you deposit your coin in their address. Take a look.
