"Quantum computing headlines are everywhere and they’re scaring a lot of crypto holders. But how real is the threat, really? Should you be worried about your coins? Is the industry at risk?
In this video, we go for a deep dive into a recent crypto report to separate the genuine risks from all the FUD. If you care about crypto’s long term future, this is essential viewing."

This video explores whether quantum computing poses an existential threat to cryptocurrency by analysing a report from a16z crypto that aims to separate realistic concerns from hype. The presenter explains that while a cryptographically relevant quantum computer could theoretically break the encryption protecting digital signatures, such technology is likely a decade or more away due to the immense difficulty of creating stable, error-corrected logical qubits. A major distinction is made between harvest now decrypt later attacks, which threaten long-term private data and privacy-focused coins, and the signature-based security of networks like Bitcoin, which are forward-looking and can be mitigated through future upgrades. For Bitcoin specifically, the challenges lie more in governance and the slow coordination required for a network-wide migration to post-quantum signatures, rather than immediate technical collapse. The video concludes with recommendations for developers to begin planning hybrid security solutions now without rushing into flawed implementations, emphasizing that while the threat is real, the industry has a significant runway to adapt and remain secure.
