ARK Invest report: Quantum computing could target ~35% of Bitcoin supply. Current quantum tech isn't a threat, but a gradual emergence of risks is outlined. ~65.4% of BTC supply (13M coins) is in non-vulnerable addresses. ~8.6% (1.7M coins) are in lost, quantum-vulnerable P2PK addresses. ~35% of supply in reusable/P2TR addresses could be migrated, posing a potential attack surface. A "crypto-quantum computer" needs thousands of logical qubits & millions/billions of gates. Advancements likely to be accompanied by global internet infrastructure developments before impacting Bitcoin security directly. #crypto #blockchain #news #BTC #Bitcoin
