According to Google, there were ~ 2825 billionaires in the world in 2019.
That's 2.825 T right there, and we're talking:
- Billionaires the world actually knows about
- Not counting folks who have 10's or 100's of billions
- Private individuals as opposed to large retirement funds
There's also the oft-and-widely forgotten fact that market cap is wildly different from actual invested funds: jut because two dudes somewhere decide to swap one AMZN share for 30K USD doesn't mean Bezos is suddenly 10x richer.All in all, while I believe 1M BTCUSD to be unrealistic, if a sizable fraction of that stashed money moves to BTC because they're looking for, e.g, an inflation hedge, there's easily another 10x to be had.
My opinion, not investment advice, goes without saying.
