The fact that a lot of altcoins appear on the cryptocurrency market, including many useless ones, is a normal process of improving them. Given that this area of the market is not yet regulated and many are tempted to fraudulently raise a lot of money through a fictitious ICO project, and this pushes many away from cryptocurrency, all the same, altcoins continue to develop at a fast pace. Even though their prices are constrained by the dominance of bitcoin. As a result, only useful and promising altcoins will remain. Now, of course, it is very difficult to figure out such a large number of coins and tokens, but over time, perhaps they will become even smaller. It is difficult to say where their further development will lead.
