Yeah that's right. I check from time to time the difference of the prices of altcoins from yobit, poloniex and cryptopia and because of the different prices in each exchange or platform, you can profit from one or a couple of alts commonly available in all of them. Though i don't do it that often because of the high deposit and withdrawal nowadays
