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

Japanese financial authorities and police have formally urged cryptocurrency exchanges to implement new withdrawal restrictions, responding to a surge in fraud and increasingly sophisticated criminal methods that are harming exchange customers across the country. This development marks a new front in cryptocurrency regulation in Japan, one of the world's most mature crypto markets. Authorities have expressed concern about the growing complexity of criminal methods and the increasing financial damage suffered by exchange users. The Japan Cryptocurrency Exchange Association, the industry's main local representative body, is expected to evaluate and implement new safeguards to protect investors and strengthen confidence in the Japanese crypto ecosystem.

Ethereum's staking token weETH is splitting from restaking as a heated debate over capping validator rewards divides the staking sector. This strategic separation distinguishes conventional Ethereum staking from higher-risk restaking exposure, creating a clear fork in the road for crypto investors seeking different risk profiles.

The move comes as the Ethereum community actively debates a proposal to limit validator rewards, a measure that could significantly reshape the staking landscape. Meanwhile, crypto investors and Ethereum stakers are closely watching how this split might affect their returns and network security, with weETH positioning itself as a more conservative option for those seeking Ethereum exposure without the additional risks associated with restaking.

The hacker behind the Coldcard wallet exploit, believed to hold 2,055 BTC (approximately $130 million) in stolen bitcoin, has resumed activity after weeks of silence, transferring 30.185 BTC (about $1.94 million) to a new wallet. This movement marks a significant development in the ongoing saga of one of the largest cryptocurrency thefts, raising concerns among exchanges and security platforms monitoring illicit funds.

The vulnerability in Coldcard, one of the most respected hardware wallets in the market, exposes significant risks to the cryptocurrency security ecosystem. With the total stolen value exceeding $130 million, authorities and blockchain analytics firms are intensifying efforts to track the funds and prevent them from being laundered or converted to fiat currency. The cryptocurrency community now awaits with anticipation the hacker's next moves and how this could impact trust in offline storage devices.

Wintermute, one of the most prominent crypto market makers, has secured crucial SEC and FINRA approval to launch a U.S. broker-dealer operation, representing a significant milestone for institutional crypto market access. The new entity will enable Wintermute to provide direct brokerage and trading services to large investors and funds in the United States, significantly expanding its already substantial presence in the American market.

This strategic expansion comes at a critical time for the crypto sector as traditional financial institutions gradually increase their exposure to digital assets. The regulatory approval serves as a vote of confidence in Wintermute's compliance protocols, potentially accelerating institutional crypto adoption in the U.S. The move could pressure other major market players to follow a similar regulatory path, bringing greater legitimacy and liquidity to the global crypto ecosystem.
