It is still very difficult to talk about the survival of altcoins. It is necessary to proceed from the fact that if altcoin projects are promising, then their coins or tokens will be in demand and, with the overall growth of the cryptocurrency market, will grow in value. Therefore, you should not worry about such altcoins. Only useless altcoins will not survive. These are the rules of any market, and rightly so. Only in this way can cryptocurrency improve.
