Bitfinex was fast, because they were paying certain transaction fees amounts, to make transactions fast. According to announcement i received from bitfinex on friday, they will start charging BTC withdrawal fees soon. So thats additional cost you have to consider, should be $2- $2.50 per withdrawal:
Up to now, Bitfinex has never charged users for these Tx Fees, as the amounts involved were relatively small. In the last two years, the fees for Bitcoin transactions, in particular, have significantly increased. At the time of writing, the recommended Tx Fee to have a Bitcoin transaction included in the next mined block is 420 satoshis/byte. For the median transaction size of 226 bytes, this results in a fee of 94,920 satoshis - about $2.20 at the current Bitcoin price.
Our users make thousands of transactions from our platform every day. The costs involved in sending all these transactions have increased to a point where we find ourselves forced to start charging our users the transaction fees.
....
On Monday, June 05, we will be updating the withdrawals interface to allow users to monitor the current Tx Fee assessed to cryptocurrency withdrawals.
