Bitcoin Slides as Hash Rate Faces Record Drawdown and Miner Capital Shifts

• Bitcoin's 30-day mean hash rate has fallen 19% since November 2025, marking the longest structural decline in network history as miners pivot to AI contracts.
• Institutional investors are selectively rebalancing crypto exposure, with Intesa Sanpaolo sharply reducing its BlackRock ETF holdings while increasing Staked Ethereum positions.
• A security incident involving Coldcard hardware wallets triggered a massive defensive sweep of retail funds from cold storage to exchanges, testing market resilience near $60,000.
• Publicly traded mining equities have surged over 430% as investors re-rate the sector as artificial intelligence infrastructure providers rather than pure Bitcoin mining assets.

Bitcoin experienced a 2.80% decline last week, closing below the critical 200-week Simple Moving Average at $63,769. Trading remained suppressed beneath $63,000 at the start of the current week, driven by a combination of returning exchange-traded fund outflows and heightened selling pressure following a major security incident involving Coldcard hardware wallets . While the attack did not compromise the underlying Bitcoin network, it triggered significant market anxiety among retail holders .

The price action occurred against a backdrop of deteriorating network fundamentals. Bitcoin's 30-day mean hash rate has fallen 19% since November 2025, dropping from 1,108 EH/s to 898 EH/s. According to Glassnode data, this nine-month decline represents the longest drawdown in the network's history . Unlike the 2021 collapse, which involved the temporary relocation of hardware, or the 2024 post-halving purge, this decline is structural .

The slump coincides with a massive capital migration where public mining firms hold over $70 billion in AI contracts . This suggests that converted capacity may never return to mining . The network has shed approximately 210 EH/s in absolute terms, more than the entire network possessed in early 2021 .

Mining difficulty has contracted 19.9% from its peak, sitting 1.1% below its level from one year ago . This is only the second time in history that difficulty has shown a negative year-over-year reading, the first being during the 2021 China mining ban . The margin squeeze has already caused casualties, with major pool Poolin filing for Chapter 11 protection .

The current environment differs fundamentally from past cycles because miners are not merely shutting down inefficient rigs; they are signing 12 to 20-year AI hosting leases for the same power capacity that previously ran ASICs . This represents a permanent shift in infrastructure utility rather than a cyclical adjustment .

Despite the hash rate decline, miner stocks have posted significant gains. Shares of companies like Core Scientific, Hut 8, and IREN have surged more than 430%. This divergence stems from the 2024 halving, which compressed mining margins to the point where some operators lost $19,000 per Bitcoin mined .

Mining companies possess substations, grid connections, and cooling infrastructure that are highly valuable to AI companies seeking compute capacity . Redirecting this capacity from SHA-256 computations to GPU-based AI workloads allows firms like TeraWulf, Cipher Mining, and Hut 8 to secure long-term hosting contracts .

These deals, totaling over $70 billion in potential value, offer more predictable, higher-margin revenue streams that do not depend on Bitcoin's volatile price or halving cycles . For investors, this signals a bifurcation between Bitcoin the asset and Bitcoin miners the equities .

Operational updates from CleanSpark highlight this strategic pivot. The company reported a peak operational hashrate of 50 EH/s in July 2026. It also sold 579 BTC during the month at an average price of $66,133, generating revenue to offset production costs.

CleanSpark's treasury holdings stabilized at 13,931 BTC, with 4,070 BTC posted as collateral for derivative transactions . This demonstrates a focus on optimizing infrastructure to deliver shareholder returns through operational excellence and disciplined capital allocation .

On the institutional side, Intesa Sanpaolo has reduced its BlackRock Bitcoin ETF holdings. The bank cut common shares by 94% to 40,723 and slashed call options exposure by roughly 99.3% in Q2 2026 .

Despite this reduction, the bank maintains a roughly $68 million position in ARK 21Shares ARKB and increased its Staked Ethereum ETF holdings from 116,000 to 350,000 shares . Analysts interpret this shift as a selective reallocation across issuers and products rather than a directional bet against Bitcoin .

This institutional movement coincides with activity from Strategy, which sold 32 BTC in late May and an additional 3,588 BTC for approximately $216 million in early July . These sales are linked to the company's Digital Credit Capital Framework .

Despite these sell-offs, Bitcoin price action remained resilient, rising 2.03% to $63,800 on August 4, driven by strong Spot ETF inflows that pulled in over $170 million . In contrast to Intesa's retreat, other major banks like JPMorgan, Wells Fargo, and Citigroup have been increasing their spot Bitcoin ETF exposure .

On-chain data revealed a security panic on July 31, 2026, when daily active addresses surged to nearly 1 million. Attackers exploited a flawed random number generator in Coldcard hardware wallets to drain approximately 1,367 BTC from 4,585 addresses .

On-chain analytics reveal that sending addresses drove the growth, while receiving addresses remained static, indicating a consolidation of funds . Transfers below 1 BTC totaled 39,600 BTC, the highest level since the FTX collapse in November 2022 .

Unlike the FTX era, where users moved coins off exchanges into cold storage, this event saw a reverse flow: coins moved from cold storage to exchanges . Galaxy Research head Alex Thorn observed sweep transactions running at 13.8 per block, significantly above baseline .

Price impact was minimal, with Bitcoin holding near $60,000 . Analysts view this as a security-driven event rather than capitulation . The key indicator to watch is whether these migrated coins remain on exchanges or begin selling .

In the broader market, onchain analytics platform Glassnode reported longest period of capitulation since the end of the 2022 bear market. The Bitcoin Cycle Position Heatmap signaled ongoing capitulation throughout 2026, indicating significant distress among weak hands .

Despite this technical weakness, Bitcoin hovered near $64,000 on August 5, buoyed by a marginal improvement in sentiment . This optimism stemmed from growing expectations that the United States and Iran could reach an agreement to open the Strait of Hormuz .

Technically, Bitcoin faces significant overhead resistance . The price is capped beneath the 50-day, 100-day, and 200-day Exponential Moving Averages at $64,652, $67,192, and $72,995, respectively .

For a bullish reversal, BTC must close above the 78.6% Fibonacci retracement level at $65,520, which could open a path to the 61.8% level at $78,490 . Momentum indicators reflect this bearish tone, with the weekly RSI in negative territory at 38 .

However, the weekly MACD bullish crossover from mid-July remains intact, offering a potential floor if support holds . The primary support zone remains around $60,000, aligning with a long-term ascending trendline .
