Bitcoin halving means miners receive 50% fewer bitcoins per completed block, making Bitcoin mining less lucrative. But halvenings historically lead to Bitcoin price increases, incentivising miners to keep mining despite the lower reward.Bitcoin mining consumes a lot of computational power and electricity, making some miners decide it is no longer viable after a halving event and withdraw their resources from the network, reducing its hash capacity. Other Bitcoin holders may decide the exit of established mining resources creates an opportunity for them, encouraging the establishment of new mining rigs.Outside of lower mining rewards, the effects of Bitcoin halving on mining are unpredictable.
