I have been thinking about the idea of there only ever being 21M Bitcoin. The question I often think about is how many BTC will there really be left once all coins have been mined? By that I mean how many have been lost like the examples below.

We all acknowledge that Bitcoin is scarce so how many will really be left? It won’t be 21M
