I believe that many altcoins will die off due to week fundamentals, all the weak projects, meme coins and speculative tokens will vanish over time. Bitcoin is more entrenched than any other crypto that's why I believe that it's strength will make sure any crypto that actually survives, must justify its existence
Actually, people used to think that this kind of question was absurd before, but now this issue is becoming a bit relevant because after a certain cycle, the bull season of bitcoin is happening but the altcoin season is not being seen in the market.
This seems to indicate that people's confidence in alternative coins investment has decreased a bit, and as a result of which the attraction of investors is currently only surrounding bitcoin. I am not saying that alternative coins will be dead, but the dominance of bitcoin in the market will increase even more so that most people will lose the desire to invest in altcoins.
