Bitcoin $BTC and Ethereum $ETH are preparing for a threat that doesn’t exist yet. The U.S. just committed up to $300M across Rigetti, D-Wave and Quantinuum to accelerate quantum computing hardware and error correction. At the same time, Ethereum is targeting December 2029 to make its base layer quantum-resistant, while Bitcoin developers are working on BIP-360 and BIP-361 to create a path away from today’s ECDSA and Schnorr signatures. The key point: 2029 is a planning deadline, not a prediction that Q-day arrives then. But the timelines are starting to converge. Quantum hardware is advancing, while crypto networks need years to coordinate upgrades and move users to safer cryptography. If quantum computing eventually becomes powerful enough to threaten today’s wallet keys, the biggest risk may not be the technology itself — but whether crypto can migrate fast enough. #BTC Price Analysis# #Macro Insights# #Altcoin Season#
