Who will mine the last mine Bitcoin?

Too Long; Didn't Read

The last Bitcoin is supposed to be mined in 2140 and will be mined within the next 10–20 years. Who will mine the last Bitcoin? The answer is simple: No one, because humanity doesn't exist anymore. Bitcoin isn’t using PoW anymore or has increased their supply limit. Bitcoin has long been replaced by a different blockchain and disappears into insignificance (80% chance) This will happen anyway within 10-20 years most likely. If we go by these estimates, this gives us an overall chance of (1-0.3) * (1–0.9) * * (0.8) *(1- 0.6) = 0.84%
