At Coingecko provides more exchange information and more coins which sometimes we cannot find on CoinMarketCap, making me prefer to use it to monitor the price of the coins sought and when to buy or sell coins, this is very helpful for me.
Coingecko was not putting very strict requirements to list a new token or coin while CMC was doing some verifications to list a new coin on its platform. The investors were interesting to know more about which is the potential coin and they were checking the small coins much more intense compared with the major coins.
