CMC is often faking data, i would not make any statistics with it.
You are right. On top of that even if CMC doesn't fake the numbers, the exchanges that feed the CMC numbers can be faking. The numbers that I feel like are closest to their actual numbers are those for BTC. I think the LTC numbers are especially faked, but I don't have any proof so I just included them as is.
But really, not sure where to get other numbers from, so I just used those.
I'll put numbers in parenthesis in the title.
Furthermore, any fake numbers will be faking liquidity in a way that makes it look higher than it is, not lower. Nobody would make liquidity look lower. So at best we can assume the numbers I posted are a best case scenerio, and the reality is very likely much worse.
