There is only 0.0025 of BTC per person

Roughly 20m BTC / 8b people = the average amount of BTC is just 0.0025 per person, which is just $123 worth of bitcoin.

So if you want to be 100x richer than average (in bitcoin), you just need to put $12k in it now, it will make you probably top 1% richest person in the world (in bitcoin).

Another math: someone here said that current average savings are $2.9K per person. So we can go 23x from here. But I think BTC will go up much more X. At the moment people don't save much, because USD is inflationary. Instead, they spend, or invest in stocks. Once people get used to the idea that saving is a good habit, and you don't need to "invest" in stocks or real-estate, then savings rate will increase. So, bitcoin will go up much more, maybe even 10m+ in our lifetime.
