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 just checked now this site and it's pretty accurate rather than coinmarketcap. The value of some cryptocurrencies are much higher than in coinmarketcap site. It will be a good help for investors for them to not relate in one market chart site, we should have a lot of online market chart so we can compare the fluctuation of cryptocurrencies.
