You have done a great job, the website look neat and the information on it are helpful.

I think your website will be better if you can do the following:
1, Add cryptocoin price widget to show the current price of bitcoin and other selected coin.
2, Try to add the live trading session of each exchange ( This is hard but highly rewarding), this will make people to see it as a cryptocoin trading arbitrage tools.
3, Add cpm banners.
