A warning from Ethereum researcher Justin Drake is making the rounds this week, and it is not easy to dismiss. Speaking to CoinDesk, Drake argued that artificial intelligence could break the elliptic-curve cryptography protecting Bitcoin and Ethereum wallets far sooner than quantum computers would — potentially within months in a worst-case scenario, not the years or decades most developers had assumed.
Drake's call for holders to enter what he described as 'bunker mode' drew a divided response from the broader crypto community. Some researchers pushed back, calling the timeline speculative. Others said the warning, even if premature, points to a real and underappreciated vulnerability: a large share of Bitcoin's supply sits in addresses whose public keys are already exposed on-chain, making them readable — and eventually attackable — if signature-breaking tools ever mature.
How Much Bitcoin Is Actually at Risk?
That question is not new, but it is gaining urgency. Bitcoin Magazine ran a detailed breakdown this week examining Bitcoin's quantum and cryptographic exposure as of block 950,000. Reused addresses, old pay-to-public-key outputs from the Satoshi era, and long-dormant wallets all factor in. The analysis found that a meaningful portion of circulating supply sits in formats that would be easier to attack if signature schemes were compromised.
The timing feels pointed. Also this week, CoinDesk reported that 100 BTC mined in 2010 — two block rewards worth roughly $8.5 million at current prices — moved for the first time in 16 years. Coins that old typically used pay-to-public-key script, the format most exposed under any future cryptographic attack. Nobody knows who moved them or why, but the event is a reminder that early Bitcoin is still out there, sitting in formats designed before modern security thinking caught up.
Institutions Are Already Reacting
Separately, Cointelegraph reported that Anchorage Digital is positioning itself to offer institutions both settlement services and self-custody options — relevant context as the AI-signature debate raises questions about where large holders should keep their coins and under what conditions.
Custody decisions that once seemed routine are now entangled with a longer-term question: if the cryptographic assumptions underneath Bitcoin wallets can be challenged by AI before quantum computers arrive, what does responsible storage look like right now? The honest answer from researchers is: we do not fully know yet. What is clear is that address hygiene matters — never reusing addresses, moving coins out of legacy script formats, and favoring wallets that implement the latest standards all reduce exposure.
What This Means for Everyday Holders
For most people, the practical steps are straightforward even if the underlying threat is complex:
- Use a modern wallet that generates a fresh address for every transaction.
- Avoid reusing Bitcoin addresses, which exposes your public key.
- If you hold coins in very old wallet formats, consider migrating them to a current standard.
- Watch for guidance from Bitcoin Core developers, who will be the authoritative voice if a credible mitigation path emerges.
Drake's warning may or may not prove accurate on its timeline. But the combination of that warning, the dormant-coin movements, and the institutional custody conversation this week all point in the same direction: how Bitcoin is held is not a detail. It is the whole ballgame.
For anyone donating Bitcoin to charity, using a current wallet with fresh addresses for each transaction is both good security practice and good custody hygiene — two things that matter whether you are giving or saving.
