There are so many exchanges available now a days that I have lost count of them. I mostly use Etherdelta as I find it easier and convenient to trade in the Ethereum based tokens. Any token created on Ethereum platform is available for trade by defualt in Etherdelta which is a great thing and one can catch real good projects early before they are officially listed.
Binance is another exchange that offers a lot of good coins if you like to invest.
