Coldcard exploit pushes July losses to $247M as second-worst month of 2026

Abstract

July 2026 was the second-worst month of the year for cryptocurrency thefts, with hackers stealing $247.4 million. This surge was primarily driven by the Coldcard exploit, which involved multiple attack waves resulting in losses estimated between $100 million and $130 million in Bitcoin from thousands of wallets. This incident highlighted that even cold storage carries significant technological risks. Other major July hacks included attacks on Bonzo Lend ($9M), SecondFi ($2.6M), AFX ($24M), and the Verus Ethereum Bridge ($7.5M).

July emerged as the second-worst month of 2026 for cryptocurrency thefts, largely due to the recent Coldcard exploit.

Hackers stole $247.4 million in crypto in July, the most this year after the $644 million stolen in April, according to DefiLlama data. The total was more than triple the $75 million stolen in June and the $60 million stolen in May.

The Coldcard exploit was the month’s biggest exploit, with at least $100 million in Bitcoin (BTC) stolen from 7,300 wallets across three confirmed attack waves, according to Galaxy Digital. The company also identified a suspected fourth wave that could bring total losses to about $130 million. DefiLlama’s hack tracker estimates losses tied to the Coldcard exploit at $115 million.

“July showed that even cold storage does not eliminate technological risks, which can put thousands of wallets at risk simultaneously,” research platform CryptoRank said in a Thursday X post.

Other notable July exploits included a $9 million hack against decentralized finance protocol Bonzo Lend, $2.6 million stolen from Cardano-based wallet SecondFi, $24 million stolen from Arbitrum-based perpetual exchange AFX and $7.5 million stolen through the Verus Ethereum Bridge.

The Essence of the Engels’ Pause is 'Social Sarcopenic Obesity'

The article argues that the concept of "Engels' Pause"—a historical period during the British Industrial Revolution where wages stagnated despite productivity gains—is experiencing a modern resurgence with AI and automation. However, the author contends the core issue is not merely a problem of wealth distribution (a "cake-sharing" problem), but a deeper systemic ailment termed "social sarcopenic obesity." This condition describes an economy that gains "fat"—measured as GDP, profits, and capital stock—while losing "muscle," which is the vitality of society itself, including community organization, collective action, social trust, and individual agency. Key mechanisms causing this muscle atrophy include administrative overreach, market and algorithmic substitution for human interaction, and a narrative that workers are replaceable by machines, which undermines their bargaining power. The author warns against the Western path of addressing wage-productivity decoupling primarily through redistributive welfare ("blood transfusion"), which treats symptoms but allows social muscles to atrophy further, leading to issues like low fertility and political polarization ("social atrophy trap"). China, the article states, is institutionally committed to avoiding the original "Engels' Pause" through policies like "two synchronizations" (aligning income with economic growth and labor remuneration with productivity). Its real challenge is to avoid the subsequent Western trap and forge a third path: fostering social vitality ("muscle growth") alongside economic development. This requires shifting social policy from providing a safety net ("transfusion") to "investing in people" ("protein") and, crucially, to enabling social "weight-bearing"—empowering communities, labor organizations, and individuals. The prescription is "economic weight loss, social muscle gain." Concrete proposals include making "two synchronizations" a hard policy constraint, conducting "social impact assessments" for major industrial policies, and promoting initiatives where "funding follows organization," such as community-based childcare and eldercare. Other measures involve integrating labor into profit-sharing structures, fostering collective bargaining in the platform economy, leveraging public computing power to prevent monopoly "rents," directing AI to augment (not replace) care work, and strengthening social muscles at the county level. The goal is to build an economy with high order and high vitality, preventing growth from consuming the very social foundations that sustain it.
