Am I paranoid or will one of these cycles be the last for bitcoin?

I’ve already heard people call bitcoin too big to fail which for most investments is a big red flag. And with quantum computing around the corner I have worries about bitcoins security, that paired with the ETF’s and investment firms, countries and banks investing in bitcoin it feels like the bubble is getting almost “too” big and I’m afraid it will pop, probably not this year yet, but maybe the cycle at the end of trumps presidency or the cycle after. Think about it, bitcoin isn’t much more than a giant meme coin, the price rises as long as there is hype, but for that to happen there needs to be constant flow of new holders. I’ve always imagined countries and investment firms to be the last to adopt crypto, and maybe they can manipulate the market for a couple of years but we have to be in the end stages of bitcoin, right?
