For one, Coinmarketcap pushes to the front many projects likely to be considered ‘pump and dump tokens’ on their home page in the ‘biggest gainers’ section at the very top of the page before you even see BTC at no.1 (mostly BSC) which I’m sure many new investors fall prey to.
Then there is the fluctuation/ discrepancy with global market cap; atm CMC says the market cap is down 8% (stands at $1.72T), whereas Coingecko shows a +6% day (stands at $2.07T). $300B just disappears, only to reappear later in the day? Why does this happen? Almost every day I’ve checked recently this has happened.
Then there are the market cap rankings which on CMC for some reason exclude a great many from the top 100 even though their marketcaps are larger than those above them (is this opinion being injected into rankings or is this just a coding error?). The list down from the 90s to 100 is remarkably different between the two:
Then there are the rewards from collecting ‘diamonds’ on CMC and the ‘candies’ in Coingecko. This is a smaller quibble, but on CMC the options mainly consist of NFTs and promotions for other projects (and are mostly limited in quantity and time available), whereas Coingecko offers e-books for furthering understanding of crypto, and discount codes for VPNs and news sites (you know, something more functional than a picture of a cartoon lion) – and they don’t appear to be limited (correct me if I’m wrong). Of course it’s effectively free (don’t look a gift horse – or a DeRace NFT Horse – in the mouth, but there’s a clear difference in tone between the two).
I guess my point is, considering CMC is the main site I see pushed for crypto rankings and info (not necessarily on this subreddit but definitely on social media in general), it falls short in multiple ways.
