I don't think we can see bitcoin price go above $10 million (8 digits) in our lifetime unless fiat is severely devalued and it definitely won't happen in next decade, in that short time $1 million is a possibility but not much past that.
I have a very strong feeling that it'll reach $10M before 2030. It doesn't matter that much if fiat is severely devaluated over time. The way I see Bitcoin is as a
game of accumulation. It is designed to make these these huge fluctuations on every bull run. There are two halvings remaining on this decade and I'll choose to wait for both of them.
But, it ain't just that. As you said, there will be inflation and to be specific
hyperinflation. Yes, I actually believe that we'll live some tragic times with the inflation of the dollar. A new term seems to be seeking across the internet:
Hyperbitcoinization.
And then we have the central bank digital currencies. Completely decentralized cryptocurrencies that provide privacy and (pseudo) anonymity like Bitcoin and Monero will be the escape of the whole system.
