Yes shitcoins will go to 0, but stop using that bs metric of "dominance" because it's made up garbage made to confuse noobs and lure them into shitcoins.
The bitcoiner spirit pushes towards building things on a strong foundation. It's about building stuff that lasts, it's about building a better future.
That's a key difference vs the fiat/shitcoiner mentality of building for today, short time gains with long term pains.
That's why nostr has a bright future.
