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
I do not want Bitcoin to kill other cryptocurrencies, but I want them to coexist and cover each other's weaknesses. This industry has evolved so much; there may be shortcomings in Bitcoin, and then there are advantages in other coins, which is natural because this industry is always evolving and improving. So, the new coins will innovate better than the first coins created.
This is the mindset of a true crypto investor and the market needs more people like you for the crypto industry to grow and become popular globally. Unlike many people who just want other cryptocurrencies to disappear or die, they just want bitcoin to be the only currency that exists. It is indeed a selfish, petty way of thinking and hinders growth and innovation not only in the crypto industry but also affects global technological development.
Bitcoin is great but unfortunately it is not absolutely perfect and can do every role, we really need altcoins in certain cases. This industry would not be possible without altcoins.
