I really excited to know in which exchange you use for your tradding.Top are given below.

2.Okex
3. Huobi
4. Kucoin
5.Gate.io etc
I always use Binance as i have many useful tool found here. I have many pair to trade there and leverage trade as well. However you may choose other exchang. Wanna know yours???
I am using Binance for trading as the exchange has a user friendly interface along with huge trading volume. With the introduction of margin trading and P2P now I think you don't need to go to any website for crypto related affairs.
