CMC and coingecko both very useful for us, i used to use both however i am confused why many coins and tokens not listing in CMC but listing in coingecko, not only coins and tokens but also many exchanges, is this because coingecko become more popular than CMC, or for something else.
both of these sites are very helpful for us to get information such as crypto price rates, market capitalization and another information related to the world of cryptocurrency traders, I personally am greatly helped by the existence of these two sites because I can easily check cryptocurrency prices in real time.
as long as both sites provide accurate and useful information for us, in my opinion, we don't need to compare the two sites, which is the best site.
