Can bitcoin respond to the quantum computing threat?

As quantum computing approaches, how quickly blockchain networks can adapt is emerging as a key challenge. Quantum computers could theoretically break digital signatures and encrypted communications, posing a serious threat to blockchain security. Post-quantum cryptography is already being adopted, and the U.S. National Institute of Standards and Technology has directed federal systems to complete a quantum-security transition by 2035. Permissioned blockchains may respond faster, while public chains such as bitcoin and ethereum must navigate community-driven proposal processes and user adoption.

It said competition is intensifying and tech companies could reduce capital spending. OpenAI signed a 2-gigawatt AI chip deal with Amazon Web Services, while Meta adopted AMD Instinct GPUs. Analysts see Nvidia’s growth slowing over the next three years.

Novogratz says something is wrong, not normal as bitcoin slumps

Galaxy Digital CEO Mike Novogratz voiced public bewilderment after bitcoin fell below $73,000, saying there was no reason for such a move and that something was going wrong. He said bitcoin was weakening despite a macro environment generally supportive of risk assets, and attributed the drop mainly to profit-taking after an unusually long rally. He also cited quantum-computing worries but said they were not yet a practical threat.
