Does anyone know what will happen in 2140 once all available bitcoins have been mined? Won't people shut off their equipment, disabling further transactions? I think a good way to solve this problem would be to change bitcoin so that there is no max limit -- maybe to change the way the rate at which coins are mined changes.
There are mining fees collected with each block processed, as long as people are using the network then bitcoin continue earning money for miners
Also, as bitcoin stabilizes the value will deflate meaning that the value will continue to rise as bitcoins are no longer produced
Not only that but the infinite divisibility of bitcoins also allows the use of the deflated currency as bitcoins become rarer
