How Long Will Bitcoin Remain Relevant in the Era of Quantum Computers?
Quantum Technology Development Forecasts
Most experts believe that the quantum threat to Bitcoin will not become serious until around 2030–2035 , meaning Bitcoin still has at least 10–15 more years of relative security.
Some forecasts are even more conservative, suggesting a timeline "ranging from a decade or two to 'not in my lifetime'" , indicating very slow progress in practical breakthroughs.
However, companies like Google aim to release a commercial quantum computer by 2029 (with over 1 million qubits) , which could accelerate the timeline unexpectedly.
Post-Quantum Solutions and Future Outlook
The Bitcoin ecosystem is already working on quantum-resistant mechanisms. For example, the QRAMP protocol has been proposed to migrate BTC to addresses secured by post-quantum cryptography .
Currently, about 75% of Bitcoin holdings are relatively safe against quantum attacks because public keys remain hidden until a transaction is made .
There is no reason to panic: "there are already engineering solutions that can ensure Bitcoin’s long-term security"【31†L36-L41}. With an innovative mindset, Bitcoin can adapt and remain relevant well into the future.
Conclusion:
Bitcoin has strong prospects for long-term relevance. Protective upgrades can be deployed well before any serious quantum breakthroughs occur, and the community’s readiness for innovation ensures that the cryptocurrency can successfully survive the quantum era.
