At block 840,000 (expected to occur around May, 2024) the bitcoin currency stock inflation rate will drop from the rate of 1.67% per year to the rate of 0.83% per year.
With each halving the decrease in the rate of currency stock inflation becomes less and less. Wider usage as a store of value and further progress towards mass adoption as a payment method will add much greater upward pressure on the price than the halving, in my opinion.
