I don’t think that math is right. It’s more of addition than multiplication.
So for every $1B purchased, it would increase to the Bitcoin on the exchange. So if there were 21m on the exchange, each Bitcoin could go up $$47.60. But if there’s only 1m Bitcoin on exchanges, it goes up $1,000.
So the multiplier is 21m / # of Bitcoin on exchanges. Currently 1.9 m on exchanges equating to a 11.05 multiplier. And that means $1B x 11.05 is added to current “market cap” which there’s different calcs for that.
Free float mkt cap according to coin metrics is currently $565 billion. So a $1B purchase could move the prive 1.95% even though with current market cap it should be dividing that by the multiplier.
If you use the standard maket cap price x 21m it only translates to a 1.33% increase in price.
So as Bitcoin keeps leaving exchanges the multiplier could double or triple in the next couple years due to halfining. Free float market cap could also dwindle while people hodl and lose access to their Bitcoin.
Unit bias would have to be crushed with about a )200-300B Bitcoin rush. The multiplier would skyrocket. FOMO would set in. But where’s that amount of capital coming from? I’m straight outta fiat.
