Don't worry about altcoins anymore. There are already more than 13,000 altcoins and they will inevitably continue to develop. Even if more than two-thirds of them will soon leave the market, all the same, the rest will continue to lift this market. The worry is for bitcoin, which is functionally outdated for a long time, but continues to grow in value. This lays a slow-motion mine for the future, although it is not a fact that it can ever work.
