maybe you can try with bittrex, in that site, you can found many coins that have big potential to increase. in 2 weeks ago until now, in bittrex, i see there is many coins that suddenly gets pump but unfortunately, i am not buying that coins so i only can watching the fast moving price. beside bittrex, i think you can visit cryptopia or coinexchange. those market is not too big but have many coins too like yobit but be careful when you decided to trading in those site, always thinking about how much money you want to use.
