for me the best exchange to trade is on mercatox. because in this exchange i born as a trader and in this exchange i earn my profit faster than a top exchange, and one thing that i love on mercatox is the gap of buy and sell orders are too far unlike on the top exchange that the gap was too close than each other.
so that exchanger bring lucky to you man.personally i 've used mercatox and it's GUI easy to operate.even newbie trader can use easily. but volume in mercatox is not big enough, i think it is disadvantages using mercatox.
