I only suggest bittrex and poloniex, I feel they are the most excellent trading place. I always played in bittrex, because I always get a trading profit there
Yes Bittrex and Poloniex, but also You But is also very good exchange, and if you following announcements of new coins you can ern very good money because those coins have small pumps, so you have chance almost every day to double money, but dont try this with large amounts. More likely with 0.05btc, or less.
