Quoinex definitely has one of the most responsive and beautiful design of the trading UI. But the withdrawal problem has plagued it since I used the platform from late 2014. I wish they would just add extra staffs to handle crypto withdrawals. It's okay to be very secure and approve everything manually but take itBit or Bitfinex approach and actually process the withdrawals multiple times in the day. I hope they will improve the biggest flaw on their system permanently soon because with the great expansion news of their site lately, it's the only thing that kept most people from using the platform.
