Don't forget that they were (supposedly) hacked and loat over 42 million Nxt. Many people don't trust them and I, for one, have difficulty trustinf any exchange with significant withdrawal fees AND that limits your daily withdrawals.
Don't get me wring, I don't think. crypsty is awesome but I do think it much more trustworthy than Bter.
Agree, Qora does need more exchanges and let's vote on Crypsty then. Bter has high withdrawal fees and high minimum trade amounts etc. You don't need to worry about these if you trade on Crypsty.
Actually Poloniex was also hacked before, but still I trust Poloniex atm. At least it did something right for Qora when ShareX became a scam.
