They have recently got greedy with the fees, they make enough money with the 5 BTC listing fee and the fee for every trade. Not sure why they need so much for withdrawal fees too. Centra cost me 6 tokens to withdraw today, they were almost 20k sats at the time. It was only 0.1 a few weeks back. ETN....10 coins...a bit of insanity with those kinda fees.
