The threshold for entry is too high, and the wealth effect is too low; this is the reason why Bitcoin cannot attract newcomers.
Meme coins and altcoins precisely compensate for what seems to be a flaw in Bitcoin; every day, there are tokens appearing on-chain that can yield 100X or 1000X, even though it is gambling, speculation, and a game of survivor bias.
Who told you to say that? It sounds as if the players don't know, but aren't we all just hoping that one day the 'survivor' will favor us?
So Bitcoin and altcoins are not important; what matters is attracting people from outside, getting more individuals into the crypto space, and that is the merit of altcoins.
Once a person enters the crypto space and experiences a bull and bear market or two, they will naturally come to understand and recognize Bitcoin, so altcoins have a positive effect on Bitcoin.
