I am wondering how many bitcoiners are out there?

I consider myself a bitcoiner and sometimes I wonder how many bitcoiners are out there. Are we pretty alone?

I would define a bitcoiner:

1. Buy bitcoin as a superior money technology or path to freedom or censorship resistant technology versus speculation.
2. Invest meaningful amount of one's net worth in it and I think 5% is meaningful.
3. Run a node to contribute to network
4. Don't plan to sell
5. Self custody bitcoin

Any estimation on how many of us out there?
