Even if those new projects came into being, which is in the market, because there are many blockchains that can process more transactions, have lesser fees, and can create blocks quickly with more rewards in tokens. But those platforms are not able to replace BTC because they are not being adopted by the crypto community and BTC has gained so much attraction and market cap and trading volume that none of the others can compete with it.
So, for the next 20 years minimum and 40 years maximum, I don't think if any other coin can come up that could give solid competition to the BTC market.
I cannot agree more with you. BTC really has become a brand, just like old and reputed companies, which are the first choice of all investors to invest money in. Why would an investor spend millions of dollars on a project with a high risk that is being launched in the market in competition with BTC? That would be so stupid, but even though, as you said, many new tokens or coins have been launched into the market, the funny thing is that most of those meme-shit coins make posts on social media platforms.
If you missed BTC, ETH, BNB, or some other two or more coins, then buy our shit coin and make 100x. Yeah, many platforms try their best to lure as many people as they can, and then all they do is rug-pull them.
Overall, if one does know the potential of BTC like you mentioned, the market cap or dominance would be great to mention here, then that person considering the new upcoming BTC would definitely delete that thought. And for OP, no, we won't ditch BTC at least. I will not do that.
