I did quite a few studies published on Steemit using the Credit Suisse Wealth Report and comparing wealth bands with the number of bitcoin addresses of a certain size. The simple conclusion is that if the top 25% by wealth tried to invest 1% 0f their wealth in bitcoin, it would absorb $4 trillion. In other words, it can’t be done at today’s prices.
In another study I illustrate how doubling the number of bitcoin investors, does not double the price but has a leveraged effect of maybe 20 times the old price.
