U.S. Senator: If Powell Is Fired by Trump, It Will Trigger a Market Collapse

April 23rd (CoinDesk) — Bitcoin analyst James Check noted that recent quantum computing advances have sparked fresh concerns about Bitcoin. A sufficiently powerful quantum computer could theoretically break Bitcoin’s elliptic curve signatures, exposing public keys—especially for wallets from Bitcoin’s early Satoshi era. However, market data suggests even a worst-case selloff would be significant but manageable, not catastrophic. An estimated 1.7 million BTC sits in vulnerable Satoshi-era addresses, translating to ~$145 billion in potential sell pressure at current prices. But data tells a different story: - Long-term holders (155+ days) typically offload 10,000–30,000 BTC daily during bull markets; the full Satoshi-era supply would take just 2–3 months to liquidate at that pace. - During the recent bear market, over 2.3 million BTC changed hands in one quarter—more than the quantum “target supply”—without a systemic market collapse. - Monthly exchange inflows near 850,000 BTC,

April 23—U.S. Indo-Pacific Command head Admiral Samuel Paparo said Wednesday the U.S. government is operating a Bitcoin network node as part of a military exercise focused on network security and defense, per The Block. Paparo made the comment while responding to a question from Republican Rep. Lance Gooden about Bitcoin’s national security implications during a Wednesday House Armed Services Committee hearing. “We’re in an experimentation phase right now: operating a Bitcoin network node—not to mine, but to monitor it and conduct operational tests—using the protocol to secure and defend our networks,” he said. Paparo emphasized the military’s interest is purely technical. He told lawmakers Bitcoin’s value to U.S. warfighting capabilities lies in “cryptography, blockchain, and reusable proof of work”—tools to boost both cybersecurity and power projection. “From a military application perspective, my interest in Bitcoin is as a computer science tool,” he noted.
