ARK Estimates 34% to 35% of Bitcoin Supply Could Be Exposed to a Quantum Attack

ARK thinks 34% to 35% of Bitcoin (BTC) supply could be exposed to a quantum attack.
Its research highlights one of the biggest long-term security questions facing Bitcoin:
- Quantum computing could potentially break Bitcoin's signature schemes or elliptic curve cryptography
- ARK estimates roughly 34% to 35% of the current Bitcoin supply is exposed under that scenario
- The threat still depends on quantum computing overcoming several major engineering hurdles first
