Bitcoin Loses 76 EH/s In Just Four Days
In early August 2025, the Bitcoin network experienced a dramatic shift in one of its key performance indicators: the hashrate. On August 8, the hashrate hit a historic peak of 976 exahashes per second (EH/s) before sharply declining to about 900 EH/s within just four days. This sudden drop signals a notable adjustment in the computing power dedicated to securing the blockchain.Key Points
- On August 8, 2025, Bitcoin's hashrate reached an all-time high of 976 EH/s.
- Within four days, the hashrate dropped by 76 EH/s to approximately 900 EH/s.
- This decline coincided with a 1.42% increase in mining difficulty at block 909216.
- The average block time has slowed to 11 minutes and 4 seconds, above the 10-minute target.
- A difficulty adjustment scheduled for August 24, 2025, may reduce difficulty by up to 9.64%, potentially restoring mining activity.
- Hashprice was $57.30 per PH/s at the record peak.
- It rose by 2.55% to $58.76 per PH/s shortly after.
- On August 11, with Bitcoin above $120,000, hashprice reached $59.78 per PH/s.
- Despite these increases, hashprice remains 4.72% below the July 14 level of $61.67 per PH/s. Analysts attribute the hashrate decline primarily to the increased mining difficulty, which compresses operational profitability even amid favorable Bitcoin prices. The divergence between rising hashprice and declining computing power reflects the high operational costs miners face, where small difficulty changes can significantly impact the economic viability of mining farms.

Record Peak Followed by Sharp Decline
The Bitcoin network’s computing power surged to an unprecedented 976 EH/s on August 8, 2025, based on the seven-day moving average. However, by August 12, this level had contracted by 76 EH/s to around 900 EH/s. This drop occurred despite ongoing strong demand and massive purchases that have supported Bitcoin’s price near annual highs. The decrease aligns with a 1.42% increase in mining difficulty at block number 909216. According to data from hashrateindex.com:Mining Challenges and Network Impact
Following the hashrate decline, the average time to produce a new block has slowed to 11 minutes and 4 seconds, exceeding the ideal 10-minute interval. This indicates a temporary imbalance between the network’s difficulty and the active mining power. If the current trend continues, the upcoming difficulty adjustment on August 24, 2025, could reduce mining difficulty by approximately 9.64%. Such a reduction would alleviate pressure on miners, potentially prompting some to reactivate idle machines and helping to stabilize block production times. This adjustment could also benefit miners with competitive energy costs, enabling them to expand their market share. Should Bitcoin’s price remain elevated, the improved profitability from lower difficulty might sustain or boost mining activity. Notably, mining revenues hit a post-halving record of $1.66 billion in July 2025. Conversely, a downturn in Bitcoin’s spot price could weaken less efficient miners, accelerating consolidation within the sector. The August 24 difficulty adjustment will be a critical test of the resilience and adaptability of mining infrastructures amid evolving technical and economic conditions.Frequently Asked Questions (FAQ)
Understanding Bitcoin Hashrate Fluctuations
Q: What is Bitcoin's hashrate and why is it important? A: Bitcoin's hashrate represents the total combined computational power being used to mine Bitcoin. It's crucial because a higher hashrate generally indicates a more secure and robust network, as it requires more power to attack. Q: What caused the recent drop in Bitcoin's hashrate? A: The article attributes the hashrate decline primarily to an increase in mining difficulty. When the difficulty increases, it becomes less profitable for miners to operate their equipment, potentially leading some to shut down less efficient machines. Q: How does mining difficulty affect the hashrate? A: Mining difficulty is adjusted roughly every two weeks to maintain an average block discovery time of 10 minutes. If more computational power (hashrate) is added to the network, the difficulty increases to compensate. Conversely, if hashrate drops, the difficulty will eventually decrease, making mining more profitable again and potentially encouraging more miners to join or reactivate their hardware. Q: What is "hashprice," and how does it relate to hashrate? A: Hashprice is a metric that estimates the revenue generated per unit of hashrate. When mining difficulty increases, the hashprice typically decreases because the same amount of Bitcoin is being mined by a larger amount of hashing power. Q: What is the significance of the upcoming difficulty adjustment? A: The upcoming difficulty adjustment on August 24, 2025, is anticipated to reduce the difficulty by up to 9.64%. This reduction could alleviate profitability pressures on miners, potentially leading to an increase in the hashrate as more mining operations become viable again.Network Performance and Mining Economics
Q: Why did the average block time slow down? A: The average block time slowed down because the hashrate decreased. With less computational power dedicated to mining, it takes longer, on average, to solve the complex mathematical problems required to create new blocks. Q: How can miners with lower energy costs benefit from these changes? A: Miners with access to cheaper electricity are less affected by increases in mining difficulty and can remain profitable even when less efficient miners struggle. A decrease in difficulty due to a hashrate drop could further enhance their profitability and market share. Q: What factors could lead to consolidation in the mining sector? A: A sustained downturn in Bitcoin's price, coupled with high operational costs (like energy), can make it difficult for less efficient mining operations to remain profitable. This can lead to consolidation as larger, more efficient mining farms acquire or outcompete smaller ones.Crypto Market AI's Take
