Quantum Computing Threat to Bitcoin Years Away: Borderless Capital

Speaking at the Global Blockchain Congress Dubai 2025, Amit Mehra, a partner at venture capital firm Borderless Capital, provided crucial insights into the quantum computing threat timeline for Bitcoin and other proof-of-work algorithms. According to Mehra, quantum computing remains in its ‘infancy’ and is unlikely to develop sufficiently to threaten Bitcoin’s security until the end of the decade. This timeline provides the cryptocurrency industry with a critical window to prepare for what could become one of the most significant security challenges in blockchain history.

Mehra’s assessment places the quantum computing threat approximately five years away, giving developers, researchers, and blockchain companies valuable time to implement quantum-resistant solutions. The extended timeline reflects the current state of quantum computing technology, which despite rapid advances, still faces significant technical hurdles before it can effectively break the cryptographic foundations that secure Bitcoin and other cryptocurrencies.

Borderless Capital is taking a forward-looking approach to quantum computing threats, with Mehra revealing that the firm is ‘diving deep into quantum compute’ as part of its strategic investment focus. The venture capital company is actively investigating how various organizations are developing quantum resistance technology, positioning itself at the forefront of what could become a critical sector in blockchain security.

The firm’s research extends beyond mere threat assessment to practical investment in quantum-resistant solutions. By monitoring companies developing post-quantum security measures, Borderless Capital aims to identify promising technologies that could protect blockchain networks against future quantum attacks. This proactive stance demonstrates the growing recognition within the investment community that quantum computing represents a fundamental long-term challenge to current cryptographic systems.

Despite the extended timeline for quantum computing development, Mehra issued a crucial warning about the potential for rapid technological acceleration. ‘People tend to underestimate the rapid evolution of technology,’ he cautioned, highlighting the unpredictable nature of technological breakthroughs that could accelerate the quantum threat timeline. This perspective underscores the importance of maintaining vigilance even while working within established development timelines.

Historical patterns in technology development support Mehra’s cautionary stance. Many transformative technologies have experienced unexpected acceleration due to breakthrough discoveries, increased funding, or converging technological advances. For Bitcoin and other proof-of-work cryptocurrencies, this means that while the immediate quantum threat may be years away, the security community cannot afford complacency in developing and implementing quantum-resistant solutions.

The potential impact of quantum computing on Bitcoin extends beyond theoretical concerns to practical security implications. Proof-of-work algorithms, which form the foundation of Bitcoin’s security model, rely on cryptographic principles that quantum computers could potentially break with sufficient processing power. This vulnerability represents a systemic risk that could undermine the entire cryptocurrency ecosystem if not addressed proactively.

Mehra’s comments highlight the broader industry recognition that quantum resistance must become a priority for blockchain developers and cryptocurrency projects. The transition to post-quantum cryptographic standards will require careful planning and coordination across the industry, as any security upgrade must maintain backward compatibility while ensuring future-proof protection against quantum attacks.

The extended development timeline for quantum computing provides the blockchain industry with a valuable opportunity to prepare systematically for future threats. Borderless Capital’s research into quantum resistance technology represents just one aspect of the broader industry effort to address this challenge. Companies across the cryptocurrency sector are beginning to allocate resources to quantum-resistant development, recognizing that early preparation is essential for maintaining long-term security.

As Mehra’s assessment makes clear, the quantum computing threat to Bitcoin is not immediate but inevitable. The industry’s response will determine whether cryptocurrencies can maintain their security advantages in a post-quantum world. With venture capital firms like Borderless Capital leading the research effort and companies worldwide developing quantum-resistant solutions, the foundation is being laid for a secure transition to post-quantum cryptography when the need becomes urgent.
