ARK Invest's Lorenzo Valente more optimistic Bitcoin will beat Q Day
- —Valente: Bitcoin is better positioned for Q Day than a year ago
- —7.1M BTC, 35% of supply, sits in addresses with exposed keys
- —ARK and Unchained outlined five stages of quantum risk in March 2026
- —BIP-360 is under consideration to harden Bitcoin's defenses
Why it matters: Quantum risk touches 35% of BTC supply, but its gradual timeline gives developers room to ship post-quantum signature upgrades.
