my ranking
1. Binance
2. Poloniex
3. Hitbtc
4. Bitfinex
5. Kucoin
6. Huobi
by the way . Binance transaction fee is only 0.05% . suitable for high volume transactions . but every transaction will leave some coin powder . hope they improve .
Seeing HitBTC on the list makes me think that you compiled a list of the biggest frauds?
