Once Bitcoin is fully mined in 2140, no more new coins will be created afterwards. However, the rate of new coin generation would have significantly slowed long before then.
Fiat money, on the other hand, doesn't have a fixed unchanging supply and it probably never will. But as an economic thought experiment, what do you think would have happened if the US Government decided to stop printing any new dollars a long time ago? Would a loaf of bread today be worth $0.01? Would the economy have stagnated due to deflation or prospered? And would the effects be different if this happened today rather than ~100 years ago?
