it is true that the number of altcoins continues to grow, but the really good ones are only a few, maybe around 70% of altcoins in the market are shit coins, so you have to be very careful in choosing altcoins
Maybe 70% altcoins are scam, but now it'll be very hard to find scam projects. I know that so many scam projects will rise more than 20 percent. The best options left for us are old coins. But unlike EOS blockchain or Ripple. 11k number isn't enough, some coins aren't listed in the coinmarketcap. As an increase in crypto numbers, I hope finally we all understand the real crypto and use case.
