If Bitcoin Drops Further, Some Miners May Switch Off — Antpool Data Explains Why

Based on Antpool data, Bitcoin's current price of around $78,000 is nearing the shutdown threshold for many mid-tier mining rigs. Models like the Antminer S19 XP+ and Whatsminer M60S are operating with minimal or no profit. If BTC drops to the $69,000–$74,000 range, even the newer S21 series could become unprofitable. However, highly efficient models like the S23 remain profitable even at much lower prices, around $44,000. A further price decline could force a wave of miner shutdowns, reducing the network hashrate and triggering a downward difficulty adjustment. This would lower costs for remaining miners, potentially signaling a market bottom, while creating short-term selling pressure as miners liquidate assets.

Does Bitcoin’s 9% volatility surge signal more BTC downside?

Bitcoin's price declined below $84,000 ahead of options expiry, showing weakening momentum with lower highs and increased selling volume. The DVOL volatility index surged 9% to 41.6, reflecting heightened demand for downside protection, though this appears linked to expiry positioning rather than a structural breakdown. The put/call ratio rose to 1.11 in the last 24 hours, indicating short-term hedging, while the overall open interest remains dominated by calls. Max pain sits at $90,000, acting as a key resistance level. Additionally, Bitcoin’s hashrate fell 12% due to U.S. winter storms and compressed miner margins, echoing a 2021 pattern where hashrate drops preceded eventual recovery. The market exhibits defensive caution rather than panic, with expiry likely amplifying near-term volatility around critical levels.

Bitcoin Critic Says Price Is ‘Collapsing,’ Says Drop In Miners Pushing Asset Into ‘Downward Spiral’

A prominent Bitcoin critic warns that Bitcoin's price is "collapsing" and claims a sharp drop in miner participation and hashrate could trigger a self-reinforcing price decline. Jacob King argues that falling prices and fixed operating costs may force miners to sell Bitcoin to stay solvent, accelerating a "downward spiral." He points to a significant short-term hashrate decline, calling it unprecedented. However, many market participants attribute the hashrate drop to temporary factors, such as extreme winter weather in the U.S. that forced miners to shut down operations voluntarily. Traders and analysts emphasize the disruption is likely temporary, not a sign of fundamental network weakness. King's views align with other bearish voices, including economist Steve Hanke and investor Michael Burry, who remain skeptical of Bitcoin's long-term prospects.

Bitcoin Hashrate Slides: US Cold Wave Knocks Mining Rigs Offline

Bitcoin's price remains under pressure below $88,000 amid weak market sentiment. A sharp, unusual drop in hashrate—from 1.133 ZH/s to 690 EH/s in two days—has raised concerns. Analyst Darkfost attributes this not to miner capitulation, but to a severe US ice storm, particularly impacting Texas-based mining operations like MARA and Foundry Digital. The weather forced widespread shutdowns due to power grid stress and high electricity costs. This may lead to longer block times and a projected -4.54% difficulty adjustment. If prolonged, miners might sell BTC to cover costs, adding further selling pressure. Technically, BTC is testing key support near $86K–$88K; a break below could target the low-$80K range.

Is Bitcoin’s top still ahead? Decoding impact of equity divergence

Bitcoin is experiencing bearish pressure and a short-term downtrend, with market sentiment suggesting a local top may be forming. However, its historical correlation with U.S. equity markets like the S&P 500 presents a potential upside opportunity. Since September 2025, Bitcoin has diverged from equities, declining roughly 30% while major indices gained. This underperformance may narrow if Bitcoin catches up through upward price movement. Key challenges include persistent capital outflows, with U.S. spot Bitcoin ETFs seeing $4.68 billion in net sales since November. Despite this, Bitcoin's price has held relatively stable, declining only about $2,900, supported by strong hashrate levels and miner accumulation. A significant risk is a $7 billion outflow from stablecoins, reflecting reduced risk appetite and posing a downside threat similar to the 2021 Terra-Luna collapse. Overall, Bitcoin could be poised for a rebound aligned with equities, but stablecoin outflows remain a critical near-term risk.

Bitcoin Hashrate Slides As Foundry USA Loses 200 EH/s In US Cold Snap

The United States winter storm has significantly impacted Bitcoin mining, with Foundry USA, the world's largest mining pool, losing nearly 60% of its hashrate—dropping from 340 EH/s to 139 EH/s. This disruption contributed to a sharp decline in the total Bitcoin network hashrate, which fell from around 1,118 EH/s to a low of 668 EH/s. As a result, average block time has slowed to 12.28 minutes, exceeding the target 10-minute interval. The network is expected to adjust its Difficulty metric in response, with an estimated 18% reduction to compensate for the loss in mining power. Meanwhile, Bitcoin's price has declined 5.7% over the past week to around $87,700.

US Bitcoin miners cut output during Winter Storm Fern as network hashrate dips

US Bitcoin mining companies, including CleanSpark, Riot Platforms, Marathon Digital, and Iris Energy, significantly reduced their daily bitcoin production during Winter Storm Fern. The extreme weather strained regional power grids, prompting miners enrolled in demand-response programs to temporarily scale back operations to prioritize residential and critical infrastructure electricity needs. On-chain data confirmed synchronized output declines, with hashrate dropping from over 1 trillion to around 760 billion. The Bitcoin network’s difficulty adjustment mechanism absorbed the temporary reduction in mining activity without affecting security or block production. The curtailments highlight the industry’s role in supporting grid stability during periods of stress.

Bitcoin Difficulty Drops 3.3% As Miners Pull Back Hashrate

Bitcoin mining difficulty has decreased by 3.28% in the latest network adjustment, dropping from 146.47 trillion to 141.67 trillion hashes. This marks the second consecutive reduction and the fifth decline in the last six adjustments since November. The decrease is attributed to a sustained drop in the network's hashrate, which fell to a multi-month low of 978.8 EH/s in mid-January. The difficulty adjustment mechanism ensures block production remains near 10 minutes per block by increasing difficulty when miners are too fast and decreasing it when they are too slow. Meanwhile, Bitcoin's price has declined over 5% in the past week, trading around $90,000.

Qubic Says Dogecoin Mining Build Is Underway, Revives 51% Attack Fears

Qubic has announced the development of a Dogecoin mining integration after a community vote selected DOGE. This move transitions the project from its previous "attention" narrative around Monero into implementation, raising renewed concerns about 51% attacks. Qubic emphasized that integrating ASIC hardware into its useful Proof-of-Work (uPoW) model requires significant engineering and protocol work, but could bring scale by incorporating Dogecoin's large mining economy. The announcement revisits security debates sparked in August 2025 when Qubic claimed a Monero "takeover demonstration" with over 51% hashrate dominance, though subsequent research found its control peaked at 23–34%. Unlike Monero's CPU-based mining, Dogecoin uses Scrypt and has merged mining with Litecoin, making a brute-force 51% attack economically challenging. Research firm 21Shares estimated it would cost billions in hardware and millions daily in electricity. A more plausible risk is Qubic incentivizing existing Scrypt miners to redirect hashpower through its system—a "vampire mining" approach.

‘BTC’s security is lower now’ – Why miners are abandoning Bitcoin for AI

The AI boom is offering Bitcoin miners a new lifeline as declining block rewards and high operational costs make mining less profitable. Companies like Bitfarms and Riot Platforms are abandoning or diversifying away from Bitcoin mining to reinvest in AI infrastructure, sometimes funding this shift by selling their BTC holdings. This exodus adds selling pressure on Bitcoin and raises concerns about network security. As block rewards continue to halve, the security budget that incentivizes miners is shrinking. Analyst Justin Bons warns that Bitcoin's security is now lower than five years ago and will keep falling until the network is potentially attacked. While miner capitulation has historically signaled a market bottom, the long-term sustainability of Bitcoin mining remains uncertain compared to the lucrative returns from AI.
