I see alot of altcoins and tokens been introduced into the market every day and I keep wondering if that is how this industry will keep growing. The number of altcoins does not translate to increase in the over all market capitalization of the cryptocurrencies market and it that means that some of the coins we currently have in the market is not needed!
It's actually good if many altcoins are introduced in the market, meaning that these altcoins are a reference for beginners to invest. But there is no guarantee, the more coins that appear, then the industry can be said to be growing.
I think all coins are needed, not this year maybe next year.
All coins basically have value, but that value is determined by demand, so there are altcoins that reach their maximum amount too quickly, although there are other influences that make them reach that maximum value in a short time.
