The relentless surge of Bitcoin's hashrate, a measure of the network's computing power, might finally take a breather. This summer's scorching heatwaves are forcing some miners to curtail operations, offering a much-needed reprieve.
Miners have been battling shrinking profits in an already crowded market. The halving event, which cut mining rewards in half, squeezed their margins further, while the hashrate kept reaching new highs. This relentless growth can be attributed to two factors: previously purchased mining rigs coming online and miners scrambling to upgrade with more efficient models to stay profitable.
However, North American summer brings scorching heatwaves, posing a challenge for miners. Their powerful machines generate a lot of heat during computations, making heat mitigation crucial. During peak summer, mitigating this heat becomes even more challenging. Miners either need more power to cool their machines or shut down operations altogether due to high energy demands from consumers. This seasonal trend has led to lower hashrate in the past two summers, resulting in a decrease in mining difficulty.
The good news for some miners is that the hashrate has already begun to dip since its March peak. This decrease in competition, coupled with lower difficulty, could be a positive sign. Additionally, some miners can earn extra income by curtailing operations during summer as part of their power purchase agreements.
