Bitcoin (BTC) Hashrate Reaches New All-Time High, Signaling Growing Network Security

The Bitcoin hashrate, a measure of the total computational power dedicated to securing the Bitcoin network, reached a new all-time high of 769.8 exahashes per second (EH/s) on October 21.

This milestone highlights the increasing resilience of the Bitcoin (BTC) network, as a higher hashrate renders the network more resistant to attacks.

According to data from BitInfoCharts, the hashrate has been on a continuous upward trajectory since 2021, largely attributed to advancements in mining hardware, such as application-specific integrated circuits (ASICs).

While an increasing Bitcoin hashrate signifies enhanced network security, it also entails rising costs for mining Bitcoin. This could impact the profitability of smaller mining firms, especially as the Bitcoin halving in 2024 will reduce block rewards.

Rising Mining Costs May Drive Smaller Firms to Consolidate or Relocate

The rising mining costs, coupled with the upcoming reduction in block rewards, might lead to consolidation among smaller Bitcoin mining firms. As the hashrate escalates, companies utilizing less energy-efficient mining equipment could face difficulties in remaining profitable.

Highlighting the significance of energy-efficient equipment in maintaining profitability after the Bitcoin halving, Nazar Khan, co-founder and COO of TeraWulf—the world’s sixth-largest Bitcoin mining company—noted that smaller mining firms may be forced to shut down or relocate to regions with lower energy costs in order to remain competitive.

Despite the challenges posed by the halving and increasing Bitcoin hashrate, TeraWulf, which is valued at over $670 million, intends to continue expanding its mining operations.

Miners Holding Bitcoin Despite Rising Mining Difficulty

Major mining firms appear to be holding their Bitcoin despite the increasing difficulty in mining the cryptocurrency. On Oct. 20, mining firms collectively sent 2,916 BTC to centralized cryptocurrency exchanges (CEXs), marking one of the lowest amounts of Bitcoin selling recorded in the past 30 days, according to data from CryptoQuant.

A previous instance of miner consolidation occurred after the May 2023 Bitcoin halving, when the hashrate dropped to a two-month low of 575 EH/s. According to James Butterfill, head of research at CoinShares, that decrease was likely caused by miners turning off their unprofitable rigs.

However, many mining firms are known to hold onto their Bitcoin, suggesting confidence in their operations despite the challenges.
