According to CoinDesk, Bitcoin's 30-day implied volatility has fallen to the 36% long-term support bottom, with prices trading in a narrow range below $65,000. Adam Haeems, Head of Asset Management at Tesseract Group, warned that in a low-volatility environment, declining trading costs actually attract traders to establish large-scale directional bets and hedge positions. Once the market breaks through key levels, market makers' passive hedging will accelerate price volatility, leading to a mean-reverting rebound in volatility. Regarding market sentiment, Paul Howard, Senior Director at Wincent, pointed out that current demand for put options has significantly weakened, but call option buying is also absent—Glassnode describes this as "no one is paying for upside, and no one is paying for downside," believing this is typically a signal that the market is approaching a cycle bottom. The divergence in price trends between DOGE and BTC also confirms the continued absence of speculative sentiment. Howard stated that the next significant catalyst could be institutional ETF fund inflows driven by positive regulatory developments such as the Clarity Act, while a breakdown in Strait of Hormuz negotiations and inflation shocks constitute major downside risks.
According to CoinDesk, the S&P 500 index has risen 3.12% this month, adding approximately $2.1 trillion in market value (equivalent to the total market cap of the entire crypto market), reaching a record high total market cap of $70.5 trillion, but Bitcoin has only risen about 2% this month, hovering near $64,600. Analysts point out that this round of stock market rise is mainly driven by AI and semiconductor individual stock narratives, rather than a broad-based recovery in risk appetite at the macro level, and Bitcoin lacks direct beneficial exposure to this. Meanwhile, the crypto market also faces multiple internal pressures: the Coldcard platform suffered a $120 million exploit, the prospects of the "Clarity Act" remain uncertain, MicroStrategy has reduced its BTC holdings for three consecutive months, and stablecoin supply continues to shrink—USDT's market cap dropped from $190 billion in April to $183 billion, and USDC's dropped from $79.5 billion to $72 billion.
According to reports from the Procuratorial Daily, an employee of a Shenzhen enterprise, under pressure from over 400,000 yuan in online loans, stole the company's core R&D data and disguised himself as an overseas hacker to demand a ransom of 0.88 Bitcoin and 90,000 USDT from the enterprise, and was ultimately sentenced to three years and three months for attempted extortion and fined 10,000 yuan.
Odaily Odaily News: Bitcoin Red Team, a bitcoin security organization composed of 16 volunteers, stated that it identified nearly 5,000 potential issues during a rapid AI-assisted review of bitcoin ecosystem projects. The organization's members include AnchorWatch CEO Rob Hamilton and bitcoin developer Calle, among others. Calle stated that Bitcoin Red Team used AI tools combined with manual review to scan for vulnerabilities in open-source code repositories related to bitcoin, discovering an average of approximately 1 critical vulnerability per person per hour. Calle disclosed that within 29.8 hours of launch, the team had identified 4,962 potential issues across 390 projects, of which as many as 720 were classified as high-risk or critical. Currently, 21.4% of the findings have been reproduced. The security review initiative was launched just days after the Coldcard hardware wallet vulnerability incident, in which stolen bitcoin exceeded $100 million in value.
Odaily News: Bitcoin News stated on the X platform that ZEUS has temporarily taken its infrastructure offline following a cybersecurity incident over the past few hours. ZEUS said the attack has been mitigated and services will remain offline until it completes a full security audit and resumes operations. ZEUS stated that no customer funds have been lost, and no customer funds are currently at risk. Customers whose Lightning Service Provider channels were closed will receive replacement channels once services are restored. Based on the current investigation, ZEUS said the incident appears to be limited to its own infrastructure, with no evidence yet suggesting it was caused by a vulnerability in Lightning node software. ZEUS added that it has been strengthening its infrastructure using trusted execution environments and the Validating Lightning Signer project, noting that the project is designed to mitigate such attacks in its upcoming architecture. ZEUS said it will continue to provide updates as the investigation progresses.
Odaily News: Aave founder Stani Kulechov published a lengthy post stating that Ethereum's EIP-8361 progressive issuance burn proposal has systemic issues. The proposal aims to gradually burn consensus layer issuance rewards, reducing the net staking yield to zero when the total amount of staked ETH reaches 60.25 million, approximately 50% of the total supply. Stani Kulechov believes that the second-order ripple effects of this proposal have not been fully modeled and could damage the foundations of the Ethereum ecosystem across multiple dimensions. He stated that a zero-yield mechanism may exacerbate staking centralization, with home validators being the first to exit due to fixed costs such as hardware and electricity, while non-yield-driven entities like ETF issuers, exchanges, and corporate treasury funds will remain. MEV rewards, which are unaffected by the proposal, would also expand the advantages of top professional operators. He also noted that individual stakers could face tax and operational risks. If tax authorities calculate taxes based on the full issuance amount and classify the burned portion as a capital loss, home node operators could experience after-tax losses. With penalty standards for faults remaining unchanged, the node recovery period after a fault could be extended by up to 14 times as net yields decline. Stani Kulechov stated that staking yields serve as the pricing benchmark for on-chain ETH interest rates. A decline in yields could cause DeFi lending and fixed-income markets to lose their pricing anchor, potentially driving on-chain capital toward stablecoins offering 4% to 5% annual returns. For institutional investors, predictable yields are a core competitive advantage of ETH relative to BTC. If yields fall to zero while volatility increases, ETH's differentiation in the store-of-value track would diminish. He also pointed out that after the proposal is implemented, MEV's share of total validator revenue could rise from the current 7% to nearly 30%, potentially incentivizing operators to prioritize relay nodes that support censorship, thereby weakening Ethereum's credible neutrality. If an MEV burn mechanism is subsequently added, validator revenue could be nearly eliminated. Stani Kulechov suggested that the proposal's authors release after-tax yield assessments for individual node operators, tax opinions from major jurisdictions, and cascade risk models for the DeFi ecosystem, while setting a non-zero net yield floor. He believes that staking centralization should be addressed directly with targeted measures, rather than by suppressing validator yields across the board.
Odaily News: Non-custodial Bitcoin swap service Boltz has indefinitely suspended its Bitcoin swap service, stating that the service will remain offline until further notice, with no timeline for restoration provided. Boltz allows users to transfer Bitcoin between the Lightning Network and the Bitcoin base layer, without the company ever holding custody of user funds. Boltz stated that over the past few months, its infrastructure has faced a continuous increase in automated, AI-assisted probing, and the team has already handled multiple exploit incidents. The company said each incident was contained, but the speed at which attackers iterate has outpaced the team's ability to discover and patch vulnerabilities. Boltz disclosed that the pace of attacks has accelerated over the past few days, and after reviewing recent security scan results, the company concluded that it cannot responsibly re-enable the swap service. Its API remains available for processing collaborative refunds, unilateral refunds remain operational as they do not rely on Boltz infrastructure, and customer support remains accessible.
Odaily News: Hardware wallet manufacturer Ledger has stated that the recent Coldcard vulnerability indicates the hardware Bitcoin wallet industry needs to reassess its security model. Ledger CTO Charles Guillemet stated that Ledger devices were not affected, as their recovery phrases are generated by a hardware random number generator built into a certified secure element. Coldcard manufacturer Coinkite disclosed last week that its air-gapped Coldcard Bitcoin hardware wallet contains a vulnerability traceable to firmware versions from March 2021. The vulnerability uses a software fallback mechanism to generate wallet recovery seeds, allowing certain private keys to be guessed, with related losses reaching approximately $130 million. Coinkite released a fixed firmware on Sunday and urged affected users to transfer funds to newly generated wallets. Charles Guillemet stated that open source is different from being audited — the flaw had existed in public code for over five years, and AI is enabling attackers to scan code and identify vulnerabilities at machine speed. Charles Guillemet also said that over the past two years, Ledger has combined AI with security engineers and cryptography experts to review code and identify vulnerabilities. He believes that when evaluating hardware wallets, users should understand how randomness is generated and whether that process has received independent certification.
Odaily Planet Daily reported that Bitcoin News stated on the X platform that Coinkite said the vulnerability existed at the boundary between two unrelated firmware submodules, rather than in its Bitcoin or encryption code, which allowed it to evade both manual and AI-assisted code reviews for years. Coinkite stated that after the incident, the company tested cutting-edge AI models including Kimi K3, Claude Fable, and Codex 5.6, none of which identified the flaw. Coinkite is now urging security-critical projects to specifically audit build systems and submodule boundaries, and warned that AI-assisted development could leave similar blind spots in the Bitcoin ecosystem.
Galaxy Digital Head of Research Alex Thorn stated that based on new victim reports received following the incident, the number of attackers exploiting the Coldcard vulnerability has reached at least 15.Thorn noted that information provided by victims helped the research team uncover previously unidentified attack activity. Unlike thefts from centralized exchanges, correlations between the attackers in this vulnerability exploit require confirmation through on-chain analysis and victim feedback.He added that a single victim reporting less than 1 BTC stolen helped the team discover a previously unknown attack, which siphoned approximately 12 BTC from 126 addresses.According to Galaxy Research's earlier estimates, the Coldcard vulnerability has led to at least three rounds of attacks, with losses amounting to approximately $100 million in BTC. Additionally, Galaxy has identified a suspected fourth round of attacks, which could bring total losses to approximately $130 million.Meanwhile, the incident has also sparked discussions regarding the security of Bitcoin self-custody. Dragonfly Managing Partner Haseeb Qureshi stated that "AI security hardening costing around $2" could potentially have prevented this vulnerability, and noted that some AI models were able to rediscover related vulnerabilities within a relatively short timeframe. However, industry insiders pointed out that current claims about the speed of AI discovering vulnerabilities lack rigorous blind testing and verification.Researchers believe that as AI model capabilities improve, the costs of vulnerability discovery and attacks in the crypto industry may continue to decline, requiring wallet developers to further strengthen code audits and security protections.

According to CoinDesk, the 30-day implied volatility index BVIV, which measures expected volatility in the Bitcoin options market, has continued to decline, now falling to 36%, the lowest level since May 31, significantly down from the high near 60% in early June. Recent influencing factors include the Coldcard wallet attack incident involving tens of millions of dollars, weak institutional demand, and uncertainty in the regulatory and macroeconomic environment, but there are no obvious signs of panic in the market. However, volatility has mean-reverting characteristics. When the indicator falls to historical lows, a rebound often follows. Currently, BVIV has approached levels that have previously formed support multiple times. If volatility rebounds quickly in the future, it may be accompanied by a significant directional move in Bitcoin; whether up or down, traders need to remain vigilant.
Odaily News, According to blockchain detective Specter's monitoring, it has identified a cluster of wallets holding 28,600 BTC, valued at approximately $1.8 billion, suspected to be related to wallets previously attributed to the Zhimin Qian money laundering case. A few weeks ago, a Bitcoin wallet that had been dormant since 2017 transferred 1,020 BTC, valued at approximately $60 million, and began distributing funds to multiple addresses in a manner consistent with money laundering patterns. After tracing these transactions, Specter discovered that the related wallet cluster connects to addresses publicly associated with the UK's investigation into Zhimin Qian. Between 2014 and 2017, Zhimin Qian organized large-scale investment fraud in China, with over 128,000 victims. UK authorities later traced substantial criminal proceeds flowing into Bitcoin, and the Met Police ultimately seized 60,000 BTC, marking the largest cryptocurrency seizure in UK history at the time. In July 2021, UK authorities transferred the seized BTC, creating identifiable on-chain links. Following the recent transfer of 1,020 BTC, Specter identified additional wallets that collectively hold 28,600 BTC, valued at approximately $1.8 billion, and these wallets have remained largely dormant since June 2021. Based on on-chain evidence, it remains unclear whether these wallets are still controlled by the same actor, other custodians, or have already been identified by law enforcement.
According to Bitcoin.com, Fireblocks released the 2026 "Financial Grid" survey report, covering over 600 executives. The report shows that 99% of Continental European institutions and 100% of UK institutions expect regulatory policies to support digital asset development. Influenced by the clarity of the MiCA regulatory framework, 53% of European institutions have completed capital commitments before 2026, higher than the global average of 42%; as the UK's regulatory framework is still being formulated, this proportion is only 36%, but an additional 59% of UK institutions plan to complete budget allocations within 2026. In terms of product strategy, European institutions lead in tokenized money market funds (62% vs 45%) and tokenized securities; the UK is more aggressive in stablecoin issuance, with 50% of institutions planning to issue stablecoins independently, higher than Europe's 40%. Both markets list 24/7 settlement and real-time payments as primary application scenarios.
According to Cointelegraph, Coinkite, the manufacturer of Coldcard hardware wallets, disclosed that its devices have contained a random number generator (RNG) vulnerability persisting for up to five years since March 2021. The vulnerability stemmed from a firmware upgrade that mistakenly routed wallet seed generation to a less secure MicroPython pseudo-random number generator (PRNG), rather than the originally designed true random number generator (TRNG). Since code reviews only verified the existence of TRNG code without confirming whether it was actually invoked, the vulnerability remained undetected for a long period. To date, over 4,500 addresses have been compromised, with nearly $90 million worth of Bitcoin stolen. Kraken Chief Security Officer Nick Percoco stated that this incident should serve as a "wake-up call" for the hardware wallet industry, calling for the introduction of independent third-party testing mechanisms to mandate verification of whether the entropy sources actually invoked by production firmware are certified. Coinkite has suspended all device shipments and destroyed affected inventory after confirming the vulnerability, and stated it will cooperate with law enforcement agencies across multiple countries to trace the responsible parties.
According to QCP Group, the US Treasury, via the New York Fed, jointly purchased yen with the Japanese Ministry of Finance last Friday, marking the first US-Japan joint foreign exchange intervention action specifically to support the yen since 1998. Meanwhile, the US 30-year Treasury yield briefly rose to about 5.27%, hitting a new high since 2007, before falling back to 5.24%. QCP pointed out that the transmission path of this intervention to the crypto market mainly unfolds through yen carry trades—rapid yen appreciation may force investors holding yen funding positions to deleverage and buy back yen, subsequently affecting risk assets including BTC and ETH, reenacting the market volatility triggered by carry trade unwinding in August 2024. QCP reminded that current macro monitoring indicators should take the USD/JPY exchange rate, Japan funding costs, and US long-end Treasury yields into consideration; fiscal policy operations are increasingly becoming an important variable affecting the direction of global liquidity.
According to Bitcoin.com, a recent survey report released by Bearingpoint shows that 23% of Swiss adults use cryptocurrency at least occasionally, far higher than 11% in Germany and 18% in Austria. The survey was conducted by YouGov in June 2026 among over 4,000 adults in Germany, Austria, and Switzerland. The report points out that Switzerland's leading advantage stems from its Distributed Ledger Technology Act (DLT Act) officially effective in 2021, which provides a clear legal framework for crypto assets, attracting a large number of enterprises to establish operations, and driving the expansion of the "Crypto Valley" ecosystem to 1,749 blockchain companies. Additionally, 37% of Swiss respondents consider cryptocurrency an asset worth investing in, and 45% support it becoming an international reserve currency, both leading Germany and Austria. In contrast, regarding Germany, although retail adoption rates lag behind, the "meinkrypto" platform under DZ Bank and Dekabank's crypto services for the savings bank network are expected to cover approximately 80 million customers, potentially gradually narrowing the gap with Switzerland.
Odaily News Crypto analyst Murphy stated on X that on-chain data reveals a rare large-scale movement of coins by Bitcoin long-term holders (LTH) recently. Over the past two days, more than 65,000 BTC have moved on-chain each day (excluding internal transfers within the same entity), leading to a notable decline in LTH net positions.Data shows that LTH net positions had begun to deviate from their previous continuous growth trend since May this year, entering a plateau in July, with the recent large-scale transfers being relatively uncommon over the past year. Among these, approximately 14,000 BTC flowed into exchanges. Some of the funds include a transaction where a company under Trump's umbrella transferred 2,628 BTC to Crypto.com.Currently, aside from the portion flowing into exchanges, the destination and purpose of the remaining coins reduced by long-term holders remain unclear. Murphy stated that potential risks currently affecting the BTC market include: 1) Shifts in Fed monetary policy and rising rate hike expectations; 2) Inflationary pressure from Middle East tensions and oil price changes; 3) Valuation concentration in the AI sector and financing risks behind high capital expenditures; 4) Re-crowding of yen carry trade positions.
Odaily News – On July 30, the minority staff of the U.S. Senate Committee on Banking, Housing, and Urban Affairs released a new analysis raising Democratic objections to the amended draft of the CLARITY Act. The analysis states that Donald Trump’s 2025 crypto revenue amounts to approximately $1.4 billion, and that current ethics provisions still allow him to retain related business arrangements. The analysis reviews World Liberty Financial, the TRUMP meme coin, cryptocurrency investments, staking income, and other business activities, concluding that provisions restricting officials from issuing or sponsoring digital assets would not materially affect the aforementioned financial arrangements. Staff estimated approximately $799 million in revenue related to World Liberty Financial and approximately $635 million from the TRUMP meme coin. Trump’s annual financial disclosure report lists $635.1 million in royalties from a licensing agreement with CIC Digital LLC related to Celebration Coins, along with Bitcoin and Ethereum wallets each valued at over $50 million, and validator rewards obtained through staking agreements on Coinbase. The Senate draft of the CLARITY Act seeks to prohibit covered officials and their spouses from issuing or sponsoring digital assets for compensation during specified periods, while also establishing exceptions for qualified blind trusts, unauthorized third-party activities, continued use of an official’s likeness, and holding digital asset investments.
Odaily News: Coinkite, the company behind hardware wallet Coldcard, may face legal action from users who collectively lost over 1,300 BTC — valued at more than $88 million — due to a vulnerability in the mnemonic generator of certain models. Thomas Braziel, founder and managing partner of 117 Partners, is investigating product liability claims and potential class action lawsuits against Coinkite, while coordinating efforts to collect information from victims worldwide. Brazilian Bitcoin advocate Felipe Ojeda has filed a police report and will file a complaint against the company in Brazil. Cris Carrascosa, CEO of ATH21, stated that Coinkite does not assume custodial responsibility for user funds tied to its products, and any lawsuit would need to prove that Coldcard could have foreseen the attack. Ana Ojeda, head of institutional business development at Blend, noted that victims do not have an automatic right to full recovery of funds, but an investigation into liability issues can be pursued.
Odaily News: Hardware wallet company Coinkite's Coldcard wallet series has experienced a seed generation randomness vulnerability, with threat actors stealing over 1,000 BTC in the past two days. Galaxy Research data shows that as of Saturday 17:36 ET, the incident involved 1,367 BTC, with losses exceeding $88 million. To notify potentially affected users, Coinkite sent security alerts to email addresses retained through its store and newsletter system since 2019. Coldcard confirmed that the emails originated from Coinkite and stated that it has contacted all reachable addresses to the best of its ability. Coinkite has faced criticism for retaining customer email data. The company stated that its public policy explains that purchase email addresses are saved so customers can log in and verify that other information has been cleared, but it did not specify a deletion timeline, saying these addresses would be kept "temporarily." Coinkite co-founder and CEO Rodolfo Novak previously stated that the company does not store customer information, deletes customer data 90 days after purchase, and offers anonymous purchase options.
