I believe that 40 years or so a call to free lost coins will begin.

Any address that has not had a withdrawal in 40 years will be listed as an abandoned account and have 1 year or 2 years to do a withdrawal. It will will then forfeit and go back to the fund of coins left to mine.

I will be dead or 105 in 40 years. So I won't see it but in 2062 blocks will be only 0.0060986328125 coins
