Binance has a great chance for replacing bittrex and poloniex in the future. I also heard that binance doesn't have any fees on a few altcoins which is something that you don't see happening nowadays. And binance should probably hit the major ten exchanges sooner or later but it definitely will.
Not only binance, hitBTC and Kucoin are also very good exchanges with amazing potential and quite underrated so far.
Replaced? for what?
Bittrex and Poloniex might be popular and most used but still
there is no number 1 trading platform as it will based on user's preferences so what would Binance will replaced here?
Binance really getting good reviews recently and surely it will grow in the near future and will become one of the most popular trading platform. But since they are in early phase, I considered not to used them
"for now".
