Would like recommendation on best exchange to trade on and reason why you believe the exchange is better than others?
Poloniex is one of the best exchanges to trade because the fee structure is very less when compared to Bittrex or Binance and they also has no ID verification upto limit of $2000 perday.So it is bet for small traders to trade anonymously.And almost all the coins are available in Poloniex so it is best in my opinion.
I do not like Poloniex exchanges. Because this exchange has a touch interface to look at so when I use this exchange I have sometimes had to trade the wrong times and lose money by making such mistakes. I recommend using Kucoin exchange
