Look at the comments... people can't fathom BTC has higher adoption than S&P500 and Gold.
The trick is to understand 4-5% of the world use SPX+Gold as an investment while BTC is also used to solve a monetary problem - especially where capital controls or hyperinflation exists.
~4% of the world population owns SP500
~4.5% owns gold
~5% owns BTC
THE REAL QUESTION: Where does it top out?
5% → BTC is no more than a financial asset
50% → we have the separation of money and state
