You know what happened when supply limits, the demand will increase.
be careful with that thought process
the 18m coins in circulation(supply) is not the same as the 1.2m coins in exchange(supply)
in very value simplicity. if no more coins were mind today. exchange demand can increase 15x without even touching the full circulation supply tip
..
also the actual numbers of bitcoin is 2,100,000,000,000,000sats
btc(100m sats) is just an arbitory human eye visable depiction of the actual units available meaning
2.1quadrillion people can own 1 unit equally
21trillion people can own 100sat(1bit) equally
7billion people can own 3000bits(300,000sats) equally
most people life savings are just ~$25k(average) meaning 12sats can be $1
. but to get to my point.
devs are already trying to trick economic supply/demand by allowing 1000x more units of measure
they want to add 'millisats' into it
basically 1btc=100,000,000,000ms
by having more units of measure more people can have a 'share'/unit. or more people can accumilate more units of measure. thus cause a change to the supply/demand dynamic
so dont expect much rational/smart people to be affected by supply/demand in 120 years when fresh coins dry up. you will just see speculation/hype bubble pump the speculative spot price way above the underlying value next year for a temporary spike in a new ATH and settle down again when drama is over.
in short the halving is not in of itslf a value increase indicator but a speculative temporary drama event. which offers a small oppertunity for miners to profit and expand their farms where by the farms then sustain a higher value support wall
