ZachXBT Calls Hardware Wallets “Complete Garbage,” Labels Ledger the ‘Worst’ Crypto Wallet

Introduzione

Blockchain researcher ZachXBT criticizes hardware wallets, labeling them "complete garbage" and specifically targeting Ledger as the worst, arguing their frequent software updates increase security risks rather than enhancing safety. He points to major hacks, like a fake Ledger app stealing $9.5 million and a social engineering attack costing over $282 million, as evidence that threats often target user behavior, not the hardware itself. As an alternative for experienced users, ZachXBT suggests using a dedicated, factory-reset iPhone for crypto storage, citing Apple's Secure Enclave and app sandboxing. However, he acknowledges that smartphones, as online devices, cannot match the isolation of traditional cold wallets.

This week, the topic of crypto security became a relevant one because of blockchain researcher ZachXBT’s remarks on the reliability of hardware wallets in relation to self-custody of funds. In fact, his views were in contrast to the current practices and drew attention to the issue of crypto wallets’ protection in general, rather than that of hardware only. ZachXBT recommended using an iPhone instead of a hardware wallet for experienced users.

Security Threats Extend Beyond Hardware Wallets

Ledger transitioned from Ledger Live to Ledger Wallet, adding buying, swapping, staking, and yield management features. ZachXBT noted that the most serious accusation was against Ledger. Too many software updates complicate normal activities while posing additional security threats. Critics argue that every new feature expands the attack surface. It poses security threats owing to software vulnerabilities, while making no addition to the security of transactions.

These positions were justified by hacking events in which attacks did not take place on hardware but on its users. The fake Ledger application available in the Apple App Store is claimed to have stolen about $9.5 million from the accounts of its users who have revealed their recovery phrases. Another case of a social engineering attack resulted in the loss of more than $282 million by one cryptocurrency holder while interacting socially during the security procedure of a hardware wallet. Other cases involved losing USDC in an air-gapped Ledger and phishing letters with references to quantum computing breakthroughs.

Dedicated iPhones Join the Discussion about Self-Custody

ZachXBT claimed that a factory-reset iPhone specifically for storing cryptocurrencies is very safe due to the use of Secure Enclave, biometrics, and app sandboxing by Apple. Also, anonymous purchase of such a phone does not allow user data to be exposed after previous database breaches at Ledger. Yet, smartphones are online devices that will never be able to compete in terms of isolation from the Internet with traditional cold wallets. The researchers mentioned the existence of phishing crypto apps in the Apple App Store.

In Conversation with Ray Dalio: We Are Currently in an AI Bubble, with 1% of My Portfolio in Bitcoin

Ray Dalio, founder of Bridgewater Associates, warns in an interview that the current AI boom shows classic bubble characteristics, which could lead to significant economic downturns as seen in past cycles like 1929 or 2000. He explains that speculative enthusiasm, fueled by debt and overvaluation, often precedes a crash when rising rates or taxation force asset sales, causing widespread losses and recession. Dalio also outlines his "Big Cycle" theory, describing an approximate 80-year pattern where widening wealth gaps, massive government deficits, and shifting geopolitical power (like China's rise) create internal conflict and global instability. He emphasizes that we are in a late-cycle, transitional phase where traditional powers like the US and UK face decline. For personal wealth protection, Dalio advises diversification beyond cash into assets like stocks, bonds, real estate, and particularly gold, which he prefers over Bitcoin. While he holds about 1% of his portfolio in Bitcoin as a non-printable hard asset, he views gold as more secure from technological or governmental threats. Regarding AI's impact, Dalio believes it will disproportionately benefit capital owners, worsening inequality by replacing both physical and cognitive labor. He suggests that human intuition and emotional intelligence, combined with AI, will be key for future workers. On taxation, Dalio argues that wealth taxes are impractical and risk triggering asset sell-offs, reducing productive investment. He points to the UK as a cautionary example of debt, low productivity, and political strife. Geopolitically, Dalio foresees a more regionalized world, with the US showing weakness in prolonged conflicts like with Iran, akin to past imperial declines. The ideal outcome, he suggests, is coexisting powerful blocs (e.g., Americas, China-Asia Pacific) without major war.

Daily 7.2 Trillion KRW: Foreign Capital's Record Net Buying on Friday! Wall Street Says Headwinds for Korean Stock Fund Flows Have Subsided

South Korean stock market sees a dramatic shift in fund flows. On July 31, foreign investors made a record net purchase of approximately KRW 7.2 trillion in KOSPI stocks, marking a fundamental reversal from the persistent large-scale net outflows seen in previous months. This contributed to a significant narrowing of foreign net selling in July to KRW 9.8 trillion, down sharply from KRW 48.4 trillion in June and KRW 44.5 trillion in May. Simultaneously, domestic institutional pressure eased. South Korean pension funds and asset managers turned to a net buying position in July, purchasing KRW 1.0 trillion worth of KOSPI shares, contrasting with net sales in May and June. Market volatility is expected to be dampened by new financial regulations. Effective July 31, the Financial Services Commission tightened access for retail investors to single-stock leveraged ETFs by raising the minimum cash deposit requirement. Trading volumes for these products subsequently dropped to about 50% of their monthly average. Citigroup Research maintains its year-end KOSPI target of 10,000 points. The firm cites several supportive factors: the substantial easing of headwinds from capital outflows, a robust fundamental outlook for the semiconductor sector, historically low market valuations, strong economic fundamentals, and the potential for policy support from financial authorities if needed.

Thanks to Dice Rolls, Bitcoin Keys Are Stored Offline, But Not Everyone Will Do It

The article discusses using dice rolls to generate secure Bitcoin wallet seeds, providing entropy independent of potentially flawed hardware random number generators. It explains that each fair dice roll offers about 2.585 bits of entropy, with around 50 rolls needed for a standard 12-word seed phrase and 99+ recommended for higher security. This method gained attention after a vulnerability was revealed in some Coldcard hardware wallets, where a faulty firmware RNG (dating back to 2021) compromised generated keys. The analysis notes that while a dice-generated main seed was safe from this specific flaw, other Coldcard functions (like creating paper wallets, backup keys, or passwords) could still be vulnerable if they used the defective RNG. The piece argues that while dice-based entropy is technically robust, the manual process is error-prone, tedious, and unrealistic for most new users, who might make mistakes in recording or inputting rolls. It concludes that while manual entropy generation should remain an option for advanced users, the long-term goal is to develop reliable, user-friendly hardware and software that securely generates randomness without requiring specialized knowledge. Coldcard users are advised to check their firmware version and replace any secondary secrets (like paper wallet keys) created with vulnerable devices, while also considering multi-signature setups with devices from different manufacturers for added security.
