Why do you think that they look strange? I do not think that a good coin is a good volume!
Look at buy orders and you will see. Cryptopia volume is ~120 BTC and 111 BTC in orders right now, Bit-Z volume is 700 and only 12 BTC in orders. And the trade history is also strange. And 2fa, withdrawal issues. Don't want to spread FUD, but I will better wait HitBTC.
