Due to the demand of the cryptomonedas, the commissions of the miners have marked records in transfers.
This is not a good time to move small amounts because you can pay up to $ 25 for a transfer.
Transfer times are a problem for all exchangers, as they are having trouble making small quantity movements. Bitfinex put limits and prices for deposits and withdrawals, this is a bad move if you want to have volume in the interest of Bitcoin. They intend to use clients only with huge capital, that does not make Bitcoin a daily use but a long-term investment.
The last transactions are filling the block almost entirely.
