How Does a Miner’s Break-Even Electricity Cost Change Immediately after a Halving?

Immediately after a halving, a miner's break-even electricity cost per coin mined effectively doubles, assuming all other factors remain constant. Since the block reward is cut by 50%, the miner must spend the same amount of electricity to receive half the reward.

To maintain the same profit margin, the miner must either reduce their power consumption, acquire more efficient hardware, or rely on a proportional increase in the coin's market price.
