Quick reminder: After every single block halving, obviously the BTC that's being decreased block decreases as well. I'd like to play devil's advocate(though it shouldn't really be controversial) and say that the next halving would have less positive market effect compared to the past halvings.
So it is! With each halving, the share of new coins in the total volume is halved. Consequently, each subsequent halving has less and less effect on the market price of Bitcoin. Therefore, mining plays an increasingly smaller role in Bitcoin pricing.
