IF you are wanna starting a good reputable medium-tier exchange site and kucoin or bibox should be the best choices as both were running without any problem and various features available on both of exchange sites and that needs fees to be listed on both of exchange sites. The fees are not so much as what already applied by major exchange site like binance.

The trader fees look competitive with another exchange site like binance or okex. Both are having good community too. But this is the problem that is difficult to be filled by the new coins is about to meet all of the requirements.
