Coinbase advances Bitcoin’s post-quantum readiness while holding about 5% of BTC

Bitcoin’s post-quantum readiness is not just a search for stronger cryptography. It also involves moving wallets, custody systems and network validation through a complex, multi-year transition —while addressing funds whose owners cannot move them. Quantum computing presents a potential future threat to the classical cryptography that secures Bitcoin. Key takeaways A custodian holding about 5% of BTC is preparing its systems for post-quantum security. Hybrid spending paths would allow classical or quantum-resistant signatures. Exposed legacy funds require separate governance and engineering work.
