There goes a lot of bugs that have happened a few hours ago not only for coinmarketcap but also for other wallets that probably are attached their API to coinmarketcap.
Coingecko is better then Coinmarketcap. Coz CMC are not Track accurate Price in short time. But CG always Track accurate price of all coin/token. And Cmc team add all project without verify and Coingecko always verify all project before list and they are not accept unverified project
I don't know about the verification process of both websites but I think they both have their own way of verifying the authenticity of the project. But I've seen those projects when I click them that there's a note that cmc hasn't verified the liquidity of it.
