Friendly Reminder: There aren't enough BTC for even HALF of today's millionaire to own just ONE. (Reddit Bitcoin)
There will only be a maximum of 21 million bitcoins. Ever. About 4 million have been permanently LOST, bringing the maximum theoretical total to 17 million. This total number won't be reached until 2140 due to Bitcoin's issuance schedule.
Total number of millionaires (in USD value) worldwide is around 33 million (source).
The math is simple: there is not enough Bitcoin in the world for even HALF of today's millionaires to own just ONE SINGLE BITCOIN. Much less all the future millionaires that will be born as the human population approaches 10bn.
Bitcoin is SCARCE. Check out the S2F model for a good explanation of why scarcity and value correlate.
If you are able to acquire even one BTC today: Enjoy the feeling. You are an early adopter. And one of a limited few.
Edit: And never-mind the haters that will say something asinine like "my pubic hairs are limited in number too..." Your pubic hairs have zero utility, whereas every day Bitcoin proves it has extraordinary utility as the most perfect form of money humans have yet created.
That is all.
