the 21 million bitcoin will be mined in 15 years... I will be certainly not dead. Well I hope so!
You might want to recalculate that. Technically we will never reach 21 million coins but it will be a lot longer than 15 years before the subsidy goes to zero.
I thought the last coin wouldn't be mined until year 2140?
At least that's the number I've been telling my friends.
