Bitcoin and Ethereum race quantum clock as U.S. backs $300M hardware push

Bitcoin and Ethereum are converging on a 2029 timeline for quantum resistance, while the U.S. government backs a $300 million hardware push toward fault-tolerant quantum machines. The threat is not here yet, but the two networks' migration plans and the arrival of capable hardware are starting to line up on the same window. The convergence highlights a race between crypto networks hardening their cryptography and the development of machines that could break it.
