Those are quite impressive numbers, and many of us (actually all of us) can only imagine how Bitcoin would exist then and how people would interact with it, as we would not be there to witness it.
The last Bitcoin will need more than 34 years to be mined. Yes, a single BTC will take 34 years to be mined!
It will start around 2106 and take until 2140 until the last BTC is mined.
How much impact would mining rewards and halving have on the market then, when about 99% have already been mined and the remaing yet to be mined would not affect the market much.
Of course, Miners will be rewarded by transaction fees by then.
This is also a topic with many uncertainties about how motivated miners would be at that time to invest in mining rigs and electricity.
