Can we trust some new crypto-trading apps or it's better to trade with good known Binance, Poloniex, Bittrex.. ets?
Honestly, it is better to give trust to Binance, Idax, Kucoin, Coinbene, Lbank, Okex, Houbi, bitmex and Bittrex these exchange
has a good track record in this business industry and had their own huge community too and have a great volume in the market
as well. In short, they are all proven and tested.
