If you're worried about AI breaking ECDSA and wiping out your Bitcoin in the next few months, at minimal cost, here's my advice: take your pills 1️⃣ If Asymmetric cryptography falls, Bitcoin will be the least of our problems. TLS breaks, banking systems are in trouble, secure communications go out the window, and critical infrastructure becomes much easier to attack. Worrying about your coins at that point is like worrying about your Wi-Fi password while the house is on fire. 2️⃣ Nothing indicates we're anywhere near such a breakthrough. The latest mathematical results are impressive, sure. Take the recent integer multiplication result, which claims to beat the n.log n barrier with an exponent improvement of 2^-182. That's genuinely interesting mathematics, but hardly a practical breakthrough. It doesn't change our understanding of how to break ECDSA. And if your logic is that nothing can be trusted until it's proven unbreakable, congratulations. By that standard, nothing is safe, including hashes. Keep an eye on the research. Take cryptographic risks seriously. But let's not confuse theoretical progress with an imminent cryptographic apocalypse. Just take your pills.
