At coinmarketcap, we can see over 5000 altcoins officially listed. But surely more than 80% of the altcoins there died and became scams, with too many weak projects and scams causing the market to collapse as it is today. Even in 2019, I see a few projects in the top 100 that have become scams, like QKC, CMT ... In 2020, I hope the market will only have about 200 altcoins active. At that time, investors will focus on quality altcoins and help the price go up
