This is a nicely researched article. Thank you.
I have also been posting research on things like this. I reached the same conclusions as you. In other words, even most millionaires, (35 million of them according to CS), will never be able to buy a single bitcoin.
I have done quite a few studies on the distribution of bitcoin across addresses and also distribution of net wealth bands (I used the Credit Suisse Wealth Report).
I also have studies on the bitcoin addresses wealth bands. Although there are some 20 million bitcoin addresses, very few of them own more than $20 of bitcoin. It’s something like 5 million addresses have more than $20 (at $6000 per bitcoin). This means that only around one adult in 900 has any meaningful bitcoin balance of more than $20. There’s a long way to go.
Based on October’s numbers, we can see that the Dolphins and minnows ($20 to $100k of bitcoin) are growing in number by an annualised growth rate of 107%. (See my study below), It’s mathematically impossible to keep growing at that pace over the next year as there are not enough bitcoins. Therefore, either growth rate must fall, or price must be higher to accomodate the growth in numbers - with each new user buying less bitcoin at a higher price.
I have a number of blogs with varying amounts of data on this. The most recent one, (today), is here. https://steemit.com/bitcoin/@swissclive/bitcoin-s-supply-and-demand-over-the-next-12-months-based-on-current-months-figures
The sooner everyone stops talking about the bitcoin price, and starts discussing the Satoshi price, the better. Then everyone can own a Satoshi.
Satoshi price rules everything around me, BTC ;p
