In my opinion this is good step from Coinmarketcap, they do not want to list every shitcoin that comes up every day in hope it will be pumped and dumped. I hope that they review every case if the coin has anything into it first and is already trading before adding into list.
+ They should clear their listings and should consist from smaller number of cryptos which have alreade prooved that they are usable and have decent user usage.
