Im starting to worry about coinmarketcap lately, after series of deceit and spammish activity
The following are my observed reasons
1. Many dead projects still on cmc
2. Market cap is fake Cox many projects which have seized to trade adds up to the market cap
3. Cmc doesn't verify authenticity of projects before listing it
4. CMC now have ads of fake icos on their website thereby leading people to scammers
Funny enough so many NOOBS believe anything and everything dey see on cmc to be authentic
Let me stop here and anyone against it should bring a proof to counter it
Or offer more options
If everyone started to use CMC to check the prices of crypto currencies then there is no wonder from their action like these because everyone is here to make money so coinarketcap is also going to do anything to make money so don't trust them at all and there are also many accusations about CMC for the fake trading volumes and prices of crypto currencies.
I also heard about fake volumes by coinmarketcap. I personally like to compare price with converting its value on different platforms so this tricks don't work whenever they need to manipulate markets.
