I think site idea is pretty good, getting data form multi exchange, new coins info, searching for coins, charts (Specially TradingView), ranks system, sorting the list, UI....

Ideas to Improve your service:
I think you can add a quick start guide to help how to use the service.
The "Coin search... " visibility is low, try to change font color.
Viewing the site from mobile really needs for improvements.

If I found something more, I will tell you of course!
