Hot US inflation report sends bitcoin price down sharply

CPI stands for Consumer Price Index, a government report that measures how fast prices are rising across the economy. September's report came in higher than expected, which usually makes investors worry the Federal Reserve will keep interest rates higher for longer, and that hit riskier assets like bitcoin hard.

Crypto prices often move with broader market mood around inflation and interest rates, so this is more about macroeconomics than anything wrong with crypto itself.

This is a market reaction to economic data, not a sign of a crypto-specific problem or security risk. If you're holding long-term, this kind of swing is pretty normal and not something that requires immediate action.
