My account on Qryptos got finally verified after 3 weeks and 4 days wait (I registered on March 18th) even though they promise to process verifications in 1-2 weeks. This means I can withdraw my coins after enough of my ETN sell orders have been fulfilled.
Minimum withdrawal amount is 300 ETN, 50 QASH, 0.02 ETH, 0.05 XMR, 0.05 LTC or 0.005 BTC.
Maximum withdrawal amount is 30000 USD worth of coins per day and 300000 USD worth of coins per month.
It seems Qryptos doesn't currently itself take any withdrawal fees, but I have to confirm that when making first withdrawal.
