For example, I heard lot that P2PB2B is one of the bullshit exchanges because it has fake volume, but why on coinmarketcap can in the top 3?
Whereas on Coingecko P2PB2B is ranked 114, Does coingecko know if it's bullshit exchange? so it's not in the top 3 like in coin marketcap

So which one do you trust more?
