Currently global wealth distribution looks like this:
Top 1% holds 41% of all wealth
Next 8% holds 42% of all wealth
Next 23% holds 14% of all wealth
Bottom 68% holds 3% of all wealth
If bitcoin were to be distributed in the same way this is how much btc each of those groups would own (assuming a population of 8 billion people).
Top 1% would own 8,610,000 btc (0.1076 btc per person)
Next 8% would own 8,820,000 btc (0.0137 btc per person)
Next 23% would own 2,940,000 btc (0.0015 btc per person)
Bottom 68% would own 630,000 btc (0.0001 btc per person)
Owning 0.1 btc ($5,500 today) would put you in the top 1% of the global population should bitcoin become used as a global reserve currency.
We are still so early!
