Site looks neat and good.

Few points:

Add sorting option
Add which exchanges the data/price is pulled from and how you arrive at the current price.
Add a segment for ICO's
Display total market capitalization.
If possible do a ROI calculation on the ICO's/Coins.

Remember in mind, coinmarketcap is almost like a big boss in this space. Still the charts in their site is not attractive and lacking some features. You can add many other features to your site and be more interactive to make it big. This space needs exploration.
