85 critical bugs in Bitcoin apps is not a Bitcoin protocol failure. It is a warning about the software layer where users create keys, sign transactions and move funds. A coordinated review flagged 4,962 potential issues across 390 Bitcoin-related projects, including 85 critical and 635 high-severity findings. Not every finding is exploitable, but the scale is impossible to dismiss. Attackers do not need to break Bitcoin if they can break the tools wrapped around it. The most dangerous bugs are the ones users cannot detect: predictable seed generation, flawed signing logic, unsafe dependencies or vulnerabilities in wallet and exchange infrastructure. A “cold” wallet is only as secure as the code that created its keys. Now watch the response, not just the headline. The key signals are confirmed exploits, affected versions, emergency patches and whether users must migrate funds rather than simply update software. Bitcoin may remain untouched at the protocol level while the weakest app in the stack becomes the real attack surface. $BTC
