Borderless Capital: Quantum Threat to Bitcoin Unlikely Before 2030
Quantum computers could one day pose a serious risk to Bitcoin’s cryptography — but not anytime soon. According to Amit Mehra, partner at Borderless Capital, quantum technology is still in its infancy, giving the crypto industry several years to prepare.
Quantum fears, but not yet a crisis
Speaking at the *Global Blockchain Congress Dubai 2025*, Mehra emphasized that while quantum computing is advancing rapidly, its practical impact on blockchain security remains distant.
“Quantum computing is developing fast, but it’s still early,” Mehra said. “We’re closely monitoring both the progress of quantum hardware and the emerging defenses designed to protect blockchain networks.”
He explained that current quantum prototypes are not powerful enough to break modern encryption algorithms like those used in Bitcoin’s elliptic curve cryptography. However, once the technology reaches a threshold of stable qubits and error correction — expected near the end of the decade — things could change dramatically.
Borderless Capital’s quantum watchlist
Borderless Capital, a venture firm known for investing in blockchain infrastructure, is now expanding its research into quantum resilience. The fund is tracking startups working on **post-quantum encryption** and **quantum-safe key management systems**, which could help secure blockchain networks against future attacks.
According to Mehra, the firm views quantum security as one of the most underappreciated topics in crypto today. “It’s not an immediate threat,” he noted, “but ignoring it would be a mistake. The transition to quantum-resistant protocols will take years, not months.”
Why Bitcoin remains safe for now
Bitcoin’s network uses elliptic curve cryptography (ECC) to secure wallets and transactions — a system that would theoretically be vulnerable to large-scale quantum attacks using algorithms like Shor’s. But such attacks would require millions of stable, error-corrected qubits — far beyond the few thousand noisy qubits available today.
Experts estimate that breaking Bitcoin’s private keys through quantum computation would demand quantum machines millions of times more powerful than current prototypes. Until that point, Bitcoin’s design remains effectively secure, though researchers continue to explore post-quantum alternatives.
A race between innovation and security
Mehra warned, however, that human optimism often underestimates the pace of progress. “Every decade, we assume technologies will take longer to mature — and we’re often wrong,” he said.
That’s why Borderless Capital is funding early research into hybrid blockchain systems capable of **upgrading cryptographic layers without disrupting existing chains**. The goal is to ensure that once quantum computing becomes powerful enough to threaten encryption, blockchain networks can transition seamlessly to new, quantum-safe standards.
Conclusion
While quantum computing remains more of a theoretical concern than an immediate threat, the message from Borderless Capital is clear: the clock is ticking.
Bitcoin and other cryptocurrencies still have time to prepare — likely until the end of the decade — but the industry must begin developing and testing quantum-resistant security frameworks now.
For now, the quantum threat is distant, but vigilance will determine whether blockchain’s cryptographic foundations remain unshaken in the 2030s.
