CMC is nothing but just a site wherein statistics from different exchanges and the whole cryptomarket is displayed, so I don't think banning Bitmex from the said site would do anything good for the ecosystem if the same number of traders still stayed on the platform. Also, what you're pointing out on Bitmex' activities has been--one way or another--done by another exchange, in the past or even in the present.
The BTC/USD market on BitMEX is a derivatives market NOT actually spot trading Bitcoin. As a result, it has been excluded from the price and volume averages of Bitcoin.
There goes your claims and whatever it is that you're worrying about.
CMC is nothing ? It's one of most popular site in crypto world !!! Like Ethereum.org or bitcointalk.org
Look this, Coinmarketcap vs Coinpaprica (Biggest concurent)
https://trends.google.pl/trends/explore?q=coinmarketcap,coinpaprikaOk so in fact we buy for REAL MONEY physical Bitcoin....
This Money is around 1,000,000,000 $ every day ( Total btc volume 5,500,000,000 $ , Bitmex is 18% so 5.500.000.000$ x 0.18 = around 1.000.000.000$)
If Bitmex will be closed today and traders from Bitmex will buying and holding real Bitcoin then they can buy every day around 270 000 btc ( around 1,6 % of total btc supply)
So in my opinion when someone closed Bitmex today then we can make in 2 months run on BTC price from 3700 to 7200 $ ( 60 x 1,6 = 95% , 3700 x 1,95=7200 )
Someone will say now " It's don't work like that " , " Bitmex had nothing to do with btc price " , But facts are very real, too much times dumping on btc prices started on bitmex.
And think. What Bitmex do with btc which is deposited and loosed by owner . They sell it.... what can it cause ?
