Lopp says quantum threat to Bitcoin is distant, but preparations lag
- —Google estimates fewer than 500,000 qubits are needed versus 105 in its Willow chip
- —Lopp says a full migration to post-quantum signatures would take 5–15 years
- —About 2.6 million BTC, or 13% of supply, may never be migrated
- —Coinbase, holding roughly 12% of BTC, published a post-quantum readiness report
Why it matters: Bitcoin needs consensus on BIP-361 before a real threat emerges, or vulnerable coins will become a systemic risk for the market.
