I don't think it's like that as long as the cryptocurrency market exists, because that's the reason for me to believe that in the future altcoin will not be as depressing as you might think. If this industry continues to run whether it's good or bad, at least with a market with an ever-increasing volume, altcoin will also have its own function which of course will have many benefits to use.
Of course, the crypto market needs altcoins, many of them perform functions that are not available to Bitcoin, for example, create smart contracts. However, I doubt that our cryptocurrency market needs these hundreds of altcoins that currently exist on it. That is why most of them are not popular.
