i just trade altcoin and for me poloniex, bittrex, c-cex, yobit is the best place to trading altcoin.
now im trade at c-cex and buying some $fch (fastcash) at 2500sat, hope price back to 7000sat
I mainly trade at poloniex, bittrex. They are both good. Some coins are having higher volume in one of the two exchanges.
