When the weather gets hot, the mining machine can no longer run or freeze, making it harder to mine Bitcoin.

Analysis: Bitcoin hashrate growth may slow as North America enters summer and faces heat wave

According to CoinDesk reports on June 19, as North America enters summer and usher in a heat wave, Bitcoin’s computing power growth is expected to slow down in the coming months. The powerful computing equipment used by miners generates a large amount of heat during the operation process, and heat mitigation has become the biggest operational challenge faced by Bitcoin miners. According to analysts at Blockware Intelligence, the temperature of large computers such as ASICs (Application Specific Integrated Circuits) will rise significantly when they lack proper cooling measures.

In summer, in order to cope with overheating of equipment, miners need to increase power cooling equipment or close some mines, resulting in a decrease in computing power. Blockware pointed out that many miners had to reduce production in the summer, on the one hand due to overheating issues, and on the other hand because increased residential energy consumption triggered demand response clauses in miners' power purchase agreements. This seasonal phenomenon has led to lower computing power over the past two summers, which in turn has made it less difficult to mine Bitcoin blocks.

The research report of Luxor Hashrate Index also confirmed this trend, saying that with the arrival of summer in the United States, attention is being paid to whether the high temperature will force miners to reduce production, thereby inhibiting the growth of computing power. Similar situations have already been reflected in 2022 and 2023. According to Hashrate Index data, since the hash rate reached its historical peak in March this year, it has dropped by 10% to 589 EH/s. Since most miners are located in the United States, especially in hot areas such as Texas, the closure of operations by North American companies will have a significant impact on hash rate growth.
