One of the big crypto money market, the most reliable of the cryptocoin exchange and the bitcoin trading site where I have no trouble with small coins.
. I found it and started working while running from server problems in poloinex. It has been running smoothly for a few days, but transaction volumes are low, it may not be as fast as buying and selling polo.
I would go without thinking (in terms of interface) if it provides a trading facility like Poloniex, because there are so many more coins. but polo knows the job. No other coin exchange has reached this convenience and interface.
