#BTCPrediction The quantum threat to Bitcoin mainly concerns the cryptographic security used in digital signatures (notably ECDSA, the current elliptic algorithm). A sufficiently powerful quantum computer could, in theory, derive a private key from a public key, thus compromising the funds of an exposed wallet.

Here are the main issues:

1. Exposed addresses: Funds that have already been spent (and thus with a revealed public key) would be vulnerable first.

2. Shor's attack: Shor's algorithm could break ECDSA once a large-scale quantum computer becomes available.

3. No immediate threat: No current quantum machine is near this threshold. Experts talk about a timeframe of 10 to 20 years.

4. Anticipated solutions:

• Upgrade to post-quantum algorithms.

• Use non-reused addresses (unexposed public keys).

• Proposals to improve the Bitcoin protocol (e.g., Taproot + alternative signatures).

Conclusion

The threat is real but distant. The Bitcoin network has the time and capacity to adapt before quantum computers become a concrete threat. Some believe this will happen more quickly.
