That's already less than 1 full Bitcoin per person @ 21 million Total Supply
I would say this basic math screenshot is pretty accurate if BTC was divided evenly.
Of course this does not account for Whales and Cold Storage...also lost BTC.
The divided amount would probably evenly state that somewhere between .56 and .69 pp pBTC% is more realistic?
Below assume 17.5 Million in BTC Supply against an assumed evenly dispersed 22.3 Million Wallet Addresses.
Assume there are really only 15.5 Million Wallet Addresses. This leaves only .695 BTC Per Address Holder.
Worst case scenario. Imagine that there are only 12.5 Million BTC in Circulation and Storage. This would leave only near to 1/2 a BTC Per Wallet Address or .56!
With so many BTC lost, some left to be mined and still many others unexplained (Satoshi' Million BTC stock) it is quite possible, that over the span of more than a decade, this is the reality?
