According to the source, a Chinese cybersecurity watchdog alleged that the United States took control of approximately $13.2 billion in Bitcoin (BTC) around five years ago (source: Chinese cybersecurity watchdog allegation). The claim centers on BTC and highlights a multibillion-dollar figure that is material to market liquidity and headline risk, but the provided source excerpt offers no corroborating market data or official confirmations from U.S. authorities (source: provided source excerpt). Traders should treat this as an unverified allegation and monitor official statements from the named Chinese authority and any U.S. agency responses, as well as BTC spot and derivatives metrics for potential headline-driven volatility (source: provided source excerpt).
