Somewhat off-topic but this made me think of what it would be like if bitcoin becomes as wide spread as cellphones and internet.
In my mind it is still a binary outcome: succeed or fail.

If all bitcoins in existence at the moment gets divided and distributed equally to the world population then everyone would get:
13 410 950 / 7 125 000 000
= 0.00188224 BTC
= 1 882.24 bits per person


Global "wealth" apparently: $263 000 000 000 000
population 7.125 billion
263 000 000 000 000 / 7 125 000 000
= 36 912.28 $ per person

 
Some news headlines recently:
Woman working 4 jobs to make ends meet dies while napping in car between shifts
Richest 1% own 50% of world wealth- Credit Suisse report

From same report:
Prediction for 2019 is global "wealth" of $369 trillion.

369 trillion/ 14 million
= 26 357 142.85 $/bitcoin if all $ replaced by bitcoin in 2019
= 26.36 $ per bit

Did I do the math right?
It doesn't seem right but I can't find my mistake.


Edit for clarity:
I am not suggesting for a moment bitcoin will replace anything. This exercise was purely for fun playing with numbers that are too big for me to comprehend easily.
