Some of those coins are just shitcoins. CMC should remove those inactive cryptos so that newcomers won't be confused and won't create unnecessary blunder specially when investing into altcoins. If only we just focus on few cryptos I guess there will be less FUD and more adoption. Some of those shitcoins created doubts to new players in the crypto market because most of them are just launched for the devs to profit.
thats true,
many of those coins dont even have a working website,
and some that have a website spread coinminer viruses to their visitors.
pretty pathetic for such a widely used index
but indexation of crypto is decentralising quickly
