Bitcoin experienced a sharp decline of nearly 6% to $85,900 on December 13, 2025, marking its steepest daily drop since March. The downturn was part of a broader market selloff, with Ether falling over 8% to $2,776 and Solana dropping more than 9%. The decline was exacerbated by global market volatility, leveraged trading, and regulatory concerns, including warnings from China. The market turbulence led to over $400 million in liquidations, intensifying the downward pressure. Traders are exercising caution as they await upcoming U.S. inflation data and potential regulatory updates, which could further influence market dynamics.
