^ what do you expect, only Bitcoin offered, no liquidity, no instant deposit/withdrawals, started in 2014 still in beta, minimum btc to trade 0.05 BTC, min deposit 10k, minimum BTC to withdraw 0.05 btc, 1% trading fees.
Oldest exchange (i'd believe in op, haven't checked myself), yet no progress.
This could be some of the big factors I believe due to which people do not want to trade on this exchange or certainly due to no liquidity people may be refraining from this exchange. Also, not sure how is the customer service from this exchange. They should reduce the trading fees so that it can attract more customers and with higher the volume of trades they will still earn better than now as hardly people trade on it.
