>So if literally every known billionaire in the world decided to convert $1 billion of their assets to BTC
Not what I said.
The reason I mentioned the number of billionaires in the world was to point out the magnitude of money sloshing around in the existing financial system and that it would take much less than nation states giving up on their currency for BTC to do (yet another) 10x.
>its price isn't dictated by two dudes swapping one BTC at an absurd multiple of what everyone else is willing to sell for either.
I guess making a point by pushing it to the limit isn't something that is going to work here, so let me rephrase: the fact that Bezos's net worth is calculated by multiplying the number of AMZN shares he owns by the current price of the share is a completely unrealistic way of doing things.
Were he to actually convert all of his AMZN shares to cold hard cash, he would be left with a small fraction of what he currently weighs.
In the same fashion, the BTC market very much sensitive to liquidity: a very large portion of coins were acquired when the price was much lower, and the actual market depth of BTCUSD is - I suspect - rather shallow and it certainly wouldn't take "every known billionaire ..." to move it up 10x.
