It's a very interesting information.
Bitcoins: 21.000.000
People on Earth: 8.000.000.000 (a little more but let's use this number)
If you know a simple math, you can calculate how many bitcoins can have each person on Earth: 21.000.000 / 8.000.000.000 = 0.002625 btc.
Do you understand what is it mean?
