The rise of Bitcoin faces a risk that most cryptocurrency investors are not paying attention to: quantum computing, a breakthrough that threatens not only Bitcoin but also traditional finance, as many online banking systems use a variant of public key encryption. However, security experts warn that Bitcoin may be a particularly enticing target for quantum thieves. Skip Sanzeri, co-founder of QuSecure, a startup specializing in quantum-safe cybersecurity, said: “Bitcoin will become a target for crazy attacks. Banks have certain regulatory, defensive mechanisms and the ability to protect customers, while Bitcoin is the 'Wild West'. If your Bitcoin is stolen, your wallet will not compensate you.” (WSJ)
