KoinPro provides the lowest trading fee across the industry, save 1/3 cost on fees!
 "Transaction Fee", which is the cost for each trading;
 "Funding Fee", which is the cost for using leverage, If the position has been opened and closed the same day, no funding fee will occur.
 "Leverage", which is the ratio of margin to contract value. For example, 100x leverage means, to open a position worth of 1btc, you will need 1/100 of 1btc as margin. If the leverage is 50x, the margin is 1/50 of 1btc.
KoinPro currently charge a universal flat fee rate for all traders, please see Why not KoinPro charge different rates for Takers/Makers? for details.
KoinPro will add tiered structure for the fees for traders with larger volume later on.
