Bitcoin reached a record in computing power, but rising block difficulty continues to hurt miners’ profits.

Bitcoin miners found themselves under pressure from all sides in October. The sector posted a record 1.13 Zh/s hashrate in October, which indicates increased participation in Bitcoin mining. Still, increased mining difficulty, rising energy prices, and record $19B in liquidations cut into miners’ profits.

“October was a remarkable month for the Bitcoin mining market,” analysts at TeraHash told Coin Insider Daily, highlighting that the hashrate briefly crossed 1.13 Zh/s. “This growth was largely driven by North American infrastructure expansions and growing participation from Kazakhstan and the Middle East.”

Hashrate refers to the amount of computational power that participates in Bitcoin mining. This is crucial for decentralization and security, as a high hashrate makes attacks against the network more difficult. However, the metric does not automatically translate into more mining profits.

Notably, daily revenue per exahash per second (EH/s) dropped 7% compared to September, from $52,000 to $48,000. What is more, the declining Bitcoin price cut into miners’ rewards, with the hashprice falling nearly 12% month-to-date.

Bitcoin miners struggle to stay afloat

Falling Bitcoin prices also coincided with a rise in energy costs. The increase in oil and gas prices affected miners not tied to the electrical grid. In some regions, especially in Europe and the U.S., miners also had to deal with power curtailment. For this reason, the hashrate will likely fall in the near future.

“Looking ahead, a brief slowdown in hashrate growth appears likely in November, mainly due to higher energy costs and weather-related constraints. The next difficulty adjustment is expected to bring a minor decline, offering temporary relief to smaller miners,” Terahash analysts.
