I've just requested that CoinMarketcap remove the market from the KOBO page. I'll see what they say.
Coinmarketcap worked quick, Yobit price is no longer included in the market average, and because they were always heavily weighted downwards, kobocoin has increased by 87% in 1 day, lol.

What is the reason that Yobit prices were removed from the average coin price calculation? Because of low volume on their exchange?
No, because of withdrawal issues. I have requested that they sort out the withdrawal issue for 2 years now. No help or reply. The withdrawal issue is skewing the price on CMC.
I wish they would remove the market altogether so that it doesn't show up at all on their website as newcomers may still see it as a legitimate place to buy KOBO.
There are a few coins out there with the same issue and YoBit price is excluded on CMC.
