Bitcoin’s network fundamentals have strengthened notably over the past three months, with hashrate rising sharply alongside the asset’s price recovery. According to the source material, Bitcoin’s hashrate increased from 110 exahash per second (EH/s) on August 13 to about 157 EH/s at the time of writing, representing a gain of roughly 42%. During the same broad period, bitcoin traded above the $60,000 level for most of the prior 28 days, highlighting a period in which price and mining activity moved higher together.
Hashrate Recovery Signals Stronger Network Participation
The rebound in hashrate is especially notable because it came after the disruption caused by China’s crackdown on bitcoin mining earlier in 2021. The report notes that the current hashrate level is substantially higher than it was three months earlier, suggesting that miners have continued relocating, redeploying equipment, and reconnecting to the network. At certain points over the last three months, Bitcoin’s hashrate reportedly climbed as high as 180 EH/s, and it moved above that threshold three times since October 25.
In practical terms, a rising hashrate is often interpreted as a sign of greater network security and stronger miner confidence. More computing power dedicated to Bitcoin means more competition to produce blocks, and that competition tends to reflect expectations that mining remains economically viable under prevailing market conditions.
Mining Difficulty Has Become Much Tougher
As more hashpower returned to the network, Bitcoin’s mining difficulty also moved higher. The article states that the network was on track for its ninth consecutive upward difficulty adjustment, making bitcoin mining more than 50% more difficult than it was on July 17, 2021 for the following two-week adjustment period.
Difficulty adjustments are a core part of Bitcoin’s design. When more miners compete for the same block rewards, the protocol raises the difficulty to keep block production on schedule. In this case, the sustained increase in hashrate translated directly into a more competitive environment for miners, forcing operators to rely on efficient hardware, low electricity costs, and disciplined operations to preserve margins.
Mining Pool Distribution Remains Concentrated
At the time covered by the report, around 14 known mining pools were contributing hashpower to the Bitcoin network. A notable share of the hashrate, however, was categorized as “unknown” or linked to stealth miners. This unknown portion accounted for roughly 16.39 EH/s, or about 10.24% of the network, making it the fifth-largest source of hashpower by the report’s classification.
The concentration among the largest pools remained significant. Over the previous three days, the top four mining pools collectively controlled about 58.6% of the network’s processing power. F2Pool ranked as the largest pool with about 28.51% of hashrate, while Antpool followed with roughly 26%. Foundry USA held the third position at 12.69%, equivalent to around 20.32 EH/s. ViaBTC was also among the leading participants, accounting for 11.8% of global hashrate, or about 18.89 EH/s.
Below these major operators, another ten pools were also contributing to the Bitcoin chain. The distribution shows that while the network remains globally competitive, a relatively small number of large mining pools still command a majority share of processing power. That concentration remains an area of interest for analysts watching decentralization and mining infrastructure trends.
Mining Economics Still Favor Efficient Machines
The report also highlighted the earnings potential of leading ASIC miners under then-current market conditions. Based on the prevailing bitcoin exchange rate, network difficulty, and electricity costs of $0.07 per kilowatt-hour, the most profitable miners were generating approximately $34 to nearly $45 per day.
Among the strongest-performing units, the Microbt Whatsminer M30S++, rated at 112 TH/s, was estimated to earn about $44.77 per day. The Bitmain Antminer S19 Pro, rated at 110 TH/s, was close behind at roughly $44.24 per day. Meanwhile, Canaan’s flagship Avalonminer 1246, delivering 90 TH/s, was said to bring in around $34.92 every 24 hours.
The article also mentioned Bitmain’s newer Antminer S19 XP, with a hashrate of 140 TH/s. If that machine had been available in the market at the time, it could have generated approximately $58.20 per day under the same assumptions. However, the unit was not expected to go on sale until July 2022.
Price Strength and Hashrate Growth Moved in Parallel
Another central theme in the report is the relationship between bitcoin’s market price and mining activity. Bitcoin had remained above the $60,000 range since October 15, dipping below that level only once during the period referenced. As the price held firm, mining economics improved, encouraging additional hashrate to come online and reinforcing the upward trend in difficulty.
This does not necessarily mean price and hashrate move in perfect lockstep, but the alignment in this case is significant. Stronger prices improve revenue expectations for miners, while higher hashrate indicates that market participants are willing to deploy more resources into securing the network. Together, these metrics offered a snapshot of a Bitcoin mining sector that had regained momentum after months of structural shifts.
What the Data Suggests
Based on the source material, Bitcoin entered a period marked by robust network recovery, rising miner competition, and relatively healthy machine-level profitability for top-tier hardware. The 42% increase in hashrate over three months, combined with a difficulty increase of more than 50% since mid-July, underscores how quickly mining conditions can tighten when capital and equipment flow back into the ecosystem.
At the same time, the mining landscape continued to show a mix of resilience and concentration. Large pools retained substantial influence, unknown hashrate remained meaningful, and profitability depended heavily on hardware efficiency and power costs. Even so, the broader trend described in the report was clear: as bitcoin’s price stabilized at elevated levels, the network’s computational strength expanded sharply, making Bitcoin harder to mine and, by extension, more expensive to attack.
