Quantum computers could neutralise bitcoin? No basis for it within 10 years
Concerns are resurfacing that quantum computers could break bitcoin\'s cryptographic system, but an analysis says it is hard to view that as a realistic threat at current technology levels. It says there is little basis to expect a cryptographically meaningful quantum computer within the next 10 years, and it remains uncertain whether such equipment can be developed. The analysis adds that bitcoin should still continue research into post-quantum cryptography.

Glassnode says 10 percent of Bitcoin supply is structurally vulnerable to quantum computing, watch gaps by exchange
About 9.6 percent of Bitcoin\'s total supply is in a structurally unsafe state if quantum computers eventually break cryptography, an analysis said. On-chain data firm Glassnode estimated about 1.92 million BTC is tied to address types that expose public keys. It highlighted holdings linked to Satoshi Nakamoto, early-era coins and Taproot-based addresses. The analysis said theft risk is not imminent and noted wide differences in exposure across institutions and exchanges.

Bitcoin, ethereum diverge on quantum computing response strategies
As quantum computing emerges as a long-term security challenge for blockchain, bitcoin and ethereum are taking different approaches. Bitcoin is leaning toward gradual steps that preserve its existing structure, including proposals such as BIP-360 to reduce public key exposure. Ethereum is outlining a structured roadmap that treats quantum resistance as a multi-layer system upgrade, emphasising cryptographic agility. Both networks have yet to finalise solutions, and near-term market impact is seen as limited.
