Key Takeaways
- • ARK Invest's Director of Research for Digital Assets, Lorenzo Valente, says he is increasingly optimistic that Bitcoin will deploy quantum-resistant upgrades before 'Q Day,' the point at which quantum computers could break Bitcoin's cryptography.
- • ARK's 2026 white paper describes a gradual rise in quantum risk, which leaves time for protocol improvements such as post-quantum signature schemes.
- • About 35% of Bitcoin supply sits in addresses with exposed public keys that are vulnerable to quantum attacks, though many of those coins are reportedly lost or could be moved to safer addresses.
- • Quantum hardware capable of threatening Bitcoin is still years or decades away, and proposals such as BIP-360 are in progress to strengthen the network's defenses.
- • Pluang's market snapshot as of Oct 13, 2026 at 09:41 WIB shows only 5 of 50 major cryptocurrencies rising while 44 fell.
Summary
ARK Invest's Director of Research for Digital Assets, Lorenzo Valente, has expressed growing confidence that Bitcoin will implement quantum-resistant upgrades before 'Q Day,' the hypothetical point at which quantum computers could break the cryptography securing the network. The view, as reported by Pluang, follows ARK's 2026 white paper, which outlines a gradual rise in quantum risk and argues that this timeline leaves room for protocol improvements, including post-quantum signature schemes.
According to the report, roughly 35% of Bitcoin's supply is held in addresses with exposed public keys, which would be vulnerable to quantum attacks. Many of these coins are either lost or could be moved to safer address formats. Quantum hardware capable of threatening Bitcoin's security is still years or decades away, and proposals such as BIP-360 are under development to enhance the network's defenses. Holders using older or reused addresses are advised to monitor developments and consider migrating coins to quantum-resistant formats as upgrades roll out.
The quantum discussion was presented alongside Pluang's broader market snapshot as of October 13, 2026, at 09:41 WIB. Of 50 major cryptocurrencies tracked, only five rose while 44 declined. Among notable movers, GRT fell 7.93% to Rp457 with 78% sell activity, NEO dropped 7.77% to Rp43,132 despite 70% buy activity, and COTI declined 7.50% to Rp222 with 78% sell activity. Typical hold times across these assets ranged from 96 to 121 days.
