Although still in its early stages, quantum computing poses a potential future threat to Bitcoin and other proof-of-work cryptocurrencies, according to Amit Mehra, partner at Borderless Capital. Speaking at Global Blockchain Congress Dubai 2025, Mehra emphasized that his firm is deeply exploring quantum computing and the development of quantum-resistant technologies. He estimates that significant quantum computing capabilities will emerge by the end of the decade but warns that the rapid pace of technological advancements could accelerate this timeline, making post-quantum security an urgent priority.
Quantum computing, leveraging quantum physics principles, has the potential to process information at unprecedented speeds, threatening current cryptographic systems protecting digital assets. Industry voices like Charles Edwards, founder of Carpriole, stress the urgency of adopting quantum-resistant solutions soon, cautioning that failure to do so could see Bitcoin underperform compared to assets like gold.
To address these concerns, some projects like SUI Research have introduced new cryptographic frameworks to defend blockchains against quantum threats without disruptive upgrades. However, existing leading networks like Bitcoin and Ethereum still face unresolved challenges.
The US government is also reportedly considering investments in quantum technology to safeguard national security and maintain global competitiveness. As quantum computing evolves, the crypto ecosystem must accelerate efforts to ensure the resilience and security of digital currencies in a quantum-powered future.
