I'v found a website quite similar to coinmarketcap but way more stylish and profesionnal , let me know what you guys think of it :
https://www.worldcoinindex.com/ (Cryptocoin price index and market cap - WorldCoinIndex)
I have not yet had any experience with any other site besides CMC. I really find CMC to be the best if there is going to any other competitive sites around crypto currencies. The features are really so friendly and it drives me to be around this site more and more. We can compare with each coin and see the trend of respected coin's growth from its launch. This helps me to decide upon investment amount
