Due to Bitcoin's absolute scarcity and clearly defined inflation plan that can always be determined in terms of time, it cannot be otherwise than that a unit of these 21,000,000 steadily becomes more valuable and thus fragments of these units as well.
Not even 1% of people on the planet are familiar with the fundamental strength of Bitcoin. Over 99% don't know anything yet. The halvings can NOT be priced in if 99% of people don't even understand Bitcoin.
You are coming up with the assumption that the Bitcoin price will rise forever and ever.
What if all major countries in the world(USA, UK, EU, etc...) ban Bitcoin trading and mining? Will the Bitcoin price hit 100K or 1 million? I don't think so.
You are assuming that only 1% of the global population are familiar with Bitcoin. Maybe you are right, but is there a valid reason for the other 99% to care about Bitcoin(other than buying and waiting to sell at a higher price)?
Sometimes I have the feeling that most of the Bitcoiners view Bitcoin simply as a financial tool, which was created to help them make more fiat money. I understand this mindset, but there's something wrong about it.
I understand the OP's point of view; similarly to how we didn't know back in 2010 that Bitcoin would skyrocket and exceed prices of $60,000, we don't know what may happen in 2025 or 2030, and so on. The possibilities are endless, but it doesn't necessarily have to go positively; it can go both ways, one of which is what this user has suggested, and I totally agree. They say that there's no theoretical limit, but in practice, it can't rise forever.
Generally, a small percentage of the total population knows about Bitcoin, and an even smaller one possesses over 0.01 BTC, which shows that we still have a long way to go to achieve any kind of mass adoption, which in my opinion will never occur because Bitcoin is now seen as an asset and an investment rather than a currency, which was its original purpose.
There's only one way to find out: patience.
