Why shouldn’t I so optimistic on Bitcoin?

So, right now I’m kind of having delusions of grandeur. I’ve recently decided to go all in on bitcoin. I’m not able to buy much but if prices are stable for the summer getting .2 by the fall isn’t unrealistic. Recently Michael Saylor has predicted 8m bitcoin in the future. putting me at $1.6m At some undetermined date in the future assuming I’m not able to amass much more. I’m fully aware this could be 10-20 years in the future, if at all, but at this point I’m day dreaming about passive income from staking and crypto mining. Any thoughts as to why Saylor would be incorrect or I should pump my breaks on my optimism? Any price limits you don’t see bitcoin breaking? Sorry for the typo in the title
