Honestly, I don't think we can let of Coinmarketcap scot-free here. There's been a range of issues with them, and from being in some alt communities, there's a lack of support from the team and often coins will take months to get listed (unless you have internal connections), most of their exchanges listed have faked volume/very shady and they don't even bother to look in it, as well as often listing fairly obvious scam coins on their platform.
It's pretty obvious CMC doesn't do extensive due diligence with the coins/exchanges they list, which is pretty obvious for anyone involved in crypto, but I ask you, what impression does coinmarketcap give to new investors when they list scam exchanges/coins? Not a very good one, for sure.
CMC, please do your due diligence, you are making enough money off ads to afford 1-2 people doing due diligence daily for each new project, and still be able to process 10 new coins a day.
I can say that the article is legit, oleg and his team of CMA write them. I'm one of those who published articles regarding the IEO of CMA on idax, and it turns like what is written in the source.
Regarding to CMC, well, lots of concerns and issue on any coin's volume and price charts, but there's no direct proofs for that as said.
Damn man, I never knew they where such scumbags.
