- There are 8 billion people in the world. We can assume that most of them care about their sovereignty and privacy with some exceptions.

Based on Pareto principle we can assume (with a significant margin of error but there are no fool-proof stats anyway)

- 20% acted about their digital sovereignty and privacy (used VPNs) = ~1.5-2Bn

- 20% have played with crypto = 400-500M

- 20% had exposure to bitcoin = ~100M

- 20% are still holding = ~20M

- 20% use self-custody = ~4-5M

- 20% multisig = ~800k-1M

- 20% hold no KYC sats = ~200k

- 20% run a bitcoin node = ~50k

- 20% run a lightning node and/or

build/write on nostr = ~10k

- 20% run a nostr relay = ~2k

- 20% may fetch this note from their relay = 400

- 20% may read it = 80

- 20% may engage with it - 15-20

- 20% may send a zap - 3-5

- 20% may send a fat zap - 1

Still early.
