Poloniex is good and Bittrex is also good, but if you ask which exchanger is the best exchanger, it’s neither of the two. I believe the number one exchanger in the crypto platform is Binance. Why did I say it’s the number one? Because there are lots of investors going for it. People are even buying accounts from other investors to get a chance of investing through.

I’ve never been on it cause they stopped registration for new users, though I heard they do open registration for new users everyday for a limited time. As for Poloniex and Bittrex, I will choose Bittrex cause I have been making use of Bittrex for long and never had any problem with it. I never used Poloniex before, but I will advise you to stick to it since it’s in your favor.
