Are people seriously negatively voting Bitfinex without even using the exchange? Because if they did, they would find one of the most complete and advanced exchanges so far. The liquidity for all pairs something that differs it from other exchanges. Why would you want an exchange that has tons of trading pairs if their liquidity is super low? That's something that wont happen here. The customer support was very slow about 8 months ago, but now they are replying within hours. If you're a serious trader, do try Bitfinex. Only thing that keeps me from rating it 5 stars is the 10K requirement for activating the account in order to be able to trade FIAT.
