Over 35% of Bitcoin Supply Faces Potential Quantum Risk, New Data Shows
New Glassnode data shows 7.12 million BTC, representing 35.4% of Bitcoin's total supply, has public keys exposed to a potential future quantum-computing attack.
Address reuse accounts for 25.8% of supply exposure, while exchanges hold another 11.6%; approximately 1 million BTC linked to Satoshi may be permanently vulnerable if never moved.
Although no quantum computer currently exists capable of breaking Bitcoin's encryption, the growing exposure could intensify pressure for post-quantum upgrades and spark debate over freezing dormant coins.
Bullish strength: 25/100
- Most exposed Bitcoin can eliminate the identified risk by moving to fresh addresses.
- Coinbase says it has begun upgrading its custody infrastructure for post-quantum security.
- No quantum computer currently exists capable of breaking the encryption.
Bearish strength: 75/100
- 7.12 million BTC, or 35.4% of total supply, has exposed public keys.
- Approximately 1 million BTC linked to Satoshi may never be upgraded.
- A proposal could freeze coins that fail to migrate to quantum-resistant addresses.
- Quantum-related security concerns could increase uncertainty around Bitcoin's long-term security.
