There are now huge exchanges such as Bittrex, Huobi, Binance. I like it and I'm still trading in Binance right now, and nothing has happened yet. I am completely assured.
Making the right choice regarding that of the trading exchange is the most important thing to do as this is something which will then play a major role in deciding the amount of profit which you will then be having. It is better to go for Bittrex as this is the most praised and most favorable trading exchange by most of the traders and that it can help you in doing trading without any fear.
