Regarding, your second question, I really can't remember when I was asked for my ID (or any other documents), because I register way back in 2013... I think much had changed from then. Sorry I can't help you with this.
just want to ask too. where you withdraw your fiat ? so you trade to growing your bitcoin, and never withdraw from bitfinex except bitcoin ?
i want move from huobi to bitfinex.
Exactly, I trade to grow my btc. If I need fiat, I widraw BTC and use other exchange services. Bitfinex is offering Bank Wire (min 100$) for deposits and widrawals of fiat.
I never used this Bank wire thing , is it something available for all banks in the world ? or just few like SEPA ?
As far is I know, Bank wire is available for all banks.
