Very comprehensive and educative comment so far. I got more interested in the part where you talked about Bitcoin being a decent but high-risk investment which many folks jump into without proper preparations in terms of gaining knowledge and having a comfortable business or job that can give them enough capital to invest in. Frankly speaking, there is more to Bitcoin apart from the primary nature of it. Having a realistic mindset towards it will surely yield good results. The reason why I say this is because I have come to notice that people who got rich quickly in Bitcoin was because they have a realistic mindset, and most of them got lucky at the appropriate time. Without their mindset and consistency in Bitcoin, they would have not been lucky enough to get rich. It's not a mystery or a fairy tale, it was a preparation that meets luck. Imagine a scenario where Bitcoin moves directly to 300k what will those who didn't invest but procrastinate say those who have invested in it might become rich luckily even those who just started a few days, weeks, or months depending on the amount they had invested.
One of the reasons why most of them got lucky at the right time is that they were never too late to buy Bitcoin i.e. they never thought that the best time for Bitcoin would come. A trend among them was that all times are the best time to buy bitcoins and anytime you can buy bitcoins if you have the financial capacity.

The way Bitcoin prices have increased from 2009 to 2024 is still regretting those who failed to buy or invest in Bitcoin during this period. Likewise, if the price of Bitcoin hits $300k as you imagine, even if no one buys Bitcoin for investment, they may later regret not investing in Bitcoin.
