I've noticed a strange thing with fees that HitBTC charges if you want to buy coins for super low price.
Just try to place an order for example TNT/BTC.

Amount:  100000 TNT
Price: 0.000001 BTC

Total: 0.100000000
Fee 0.1%฿: 0.10000000

Total is 0.1 and Fee is 0.1, that makes commission 100%.

Does anyone know why?
