Tezos, Algorand, QRL are quantum ready, but where does Bitcoin stand with BIP-360?

Tezos, Algorand and QRL have introduced or are developing post-quantum protections, while Bitcoin has no quantum-resistant upgrade deployed. BIP-360 proposes a new output type intended to reduce exposure to quantum attacks, but it is still a proposal rather than an adopted network change. Bitcoin’s large existing stock of exposed public keys and the need for broad consensus make migration a long-term coordination challenge. Quantum threats are not considered imminent, but the gap highlights the importance of beginning upgrade planning before practical attacks become feasible.
