Take this into account, 1000 users possess with 40% of Bitcoin. Bill Gates alone has 5% of all dollars. There is always somebody who owns a significant amount of the asset.
This is completely false and misleading.
Bill Gates has most of his wealth in stock (assets) and even if he converted it all into USD, he would only have <2% [1] of the monetary supply but no control [2].
Bill Gates has the same value as 0.13% of the networth of the USA measured only in households and non-profit organizations [3].
Bill Gates has the same value as 0.5% of the value of the companies on the New York Stock Exchange [4].
