Quantum computing threat to Bitcoin security intensifies ahead of 2028, sparking debate and investor caution.

Concerns over quantum computing breaking Bitcoin's cryptography by 2028 have intensified, with industry leaders warning of vulnerabilities. Tom Lee highlights Bitcoin's lack of consensus on quantum resistance compared to other blockchains like Ethereum and Solana, while IBM's CEO urges caution within 3-4 years. This has led investors like Jim Cramer to sell Bitcoin holdings. Bitcoin developers emphasize the network's use of digital signatures rather than encryption and are exploring upgrades like BIP-360 to enhance security. The challenge lies in achieving consensus among diverse stakeholders to implement post-quantum protections before the threat materializes, testing Bitcoin's decentralized governance and market confidence.
