How exactly does this assume BTC is divided? Or is that just word population / Bitcoin Supply?
Another way to look at it would be to divide the bitcoins in the same way as the
total wealth of the world is distributed (the "eventual distribution") and then check, how you would do.
* top
30 would have
BTC5,000 or more (100 billion USD)
* top
300 would have
BTC500 or more (10 billion USD)
* top
3,000 would have
BTC50 or more (1 billion USD)
* the top 29,000 people would have 5,000mBTC or more, a huge fortune comparable to 100 million of today's dollars.
* the top 1 million people would have 500mBTC or more, corresponding to 10 million or more dollars
* 29 million people have at least 50mBTC, which puts them among the most affluent 0.6%, previously called 'millionaires'
* the upper middle class of 350 million people worldwide, owns 5mBTC or more
* lower middle class consists of 1 billion people is characterized by ownership of 0.5mBTC or more
* the lower class of (3+ billion) owns less than 0.5mBTC including people who don't have any or have negative worth.
Notable is the size of
BTC as the "basic" unit. It is a large unit, only applicable in displaying the total wealth of people who used to be called billionaires.
Considering that about 5 billion are in adult age, 1% is 50 million, and so on, the figures become approx as follows:
BTC5 => 0.0006% (cost to purchase today = $6,000)
BTC0.5 => 0.02% ($600)
BTC0.05 => 0.6% ($60)
BTC0.005 => 8% ($6)
BTC0.0005 => 28% ($0.60)
It is so simple that it is ridiculous. How can I be a millionaire by just investing $60. Guess what? My friend had bought 0.5% of all bitcoins existing in 2010 (it cost less than $10k to do it). He told me to do likewise. I said: "Bitcoin is so small I don't care." He said: "When it is big, it just costs more to have the same number of them."
