290% of the stolen Bitcoin remains unmoved as investigators look into a potential fourth wave that could raise losses to $130 million.

Amid escalating security challenges for cold storage solutions, recent data reveals a significant surge in funds lost to exploits targeting Coldcard wallet users. Galaxy Research reported that the total value of Bitcoin stolen across three confirmed attack waves has surpassed the $100 million mark. According to reports, this escalation reflects broader security vulnerabilities than previously estimated, placing renewed pressure on security standards within the hardware wallet sector.

Blockchain forensic analysis indicates that 90% of the stolen Bitcoin remains unmoved in the attackers' wallets, which mitigates immediate sell-side pressure on the market. However, investigators are currently looking into a potential fourth wave of attacks that, if confirmed, could raise total losses to $130 million. These developments come at a critical time for the industry, as attention focuses on the ability of custody providers to safeguard digital assets against sophisticated exploits.

Investors should monitor the results of ongoing investigations into the potential fourth wave as a key forward catalyst. Additionally, global markets are processing significant economic data that impacts risk appetite, notably the U.S. Fed Interest Rate Decision on July 29, 2026, which held rates steady at 3.75%.
