Looks good but I have been using Coinmarketcap and Coingecko ever since I started my journey in Cryptocurrency, I don't think Coinmarketcap can just go because of a similar site, they are the one that started this thing, we can just offer a comparison on their prices but I do like the interface, it's clean.
Everything has a beginning and an ending... As more people realize that coinmarketcap give inaccurate data, they will definitely ditch it use alternatives. In fact i don't think coinmarketcap is as popular as it used to be in 2017.
Actually they are not that popular indeed.
Basic research gives us an answer - type in google something like "btc usd" or other popular trading pair and you won't meet CMC even in top 3 sites most of the times.
It is on the first page still ,but thats a matter of time I believe
