He holds 140 000 BTC at this point. Nearly 1% of all BTC in circulation at the moment belongs to his company Microstrategy
It is clearly stated on that the 140k BTC is own by Microstrategy and not only Michael Saylor so any discussion further about Saylor being the world's richest man when Bitcoin touches 10m per piece is statistically wrong.
If the monetary system collapses within 10 years and BTC ever reaches 10 million dollars, he will have a net worth of 1 400 000 000 000 USD. Aside from his other assets that I'm not aware of.
Any Valuation of Bitcoin in fiat currency will be worthless once the monetary system collapses. So I'd rather see Bitcoin @ $500k with very strong global economy than $10m in an apocalyptic era.
He would be the first trillionaire and surpass Elon Musk/Bernard Arnault 5 times. But in terms of intrinsic value this may not be true. It depends on what happens to the value of their companies and assets.
Nothing to discuss because the given statistics are already proven to be wrong.
