We know that Bittrex and Poloniex are the most sought after exchangers.
But I want to know which one is best to trade? and I want to know why.
Thanks.

I used to trade on both these exchanges. Since the autumn of last year, I completely switched to Bittrex. I was tired of the heavy support of Poloniex. But now Poloniex bought out and maybe the situation will change and I will return to Poloniex again.
