You shouldn't look at past experiences to predict the future. Because that's how we ended up with altcoin market in the first place - people read stories about pumps and lambos and start chasing x1000 alts only to end up losing all their money.
Look at the fundamentals - Bitcoin is getting institutional adoption, not altcoins. Bitcoin operates for 13 years without critical bugs, network breach incidents and other problems that became normalized for altcoins. Bitcoin has proven itself, while alts are being created every day, only to disappear in a few years. Some of the alts that were top 10 some years ago are not forgotten. The same will happen with many of the current top 10.
I agree with what you said here concerning Bitcoin and other altcoins, Bitcoin has been in the news for so many years now and the testimonies of millions of people who invested and are still investing is a clear indication that Bitcoin can never vanish like some of this alts can will just appear fast and disappear the way they appeared. Bitcoin was initially not adopted by some countries and institutions but right now, so many institutions and countries are adopting Bitcoin this alone shows that Bitcoin is not like alts.
