Bitcoin briefly dropped to $80,500 after the Federal Reserve's decision, then recovered above $81,000. On-chain data shows that spot Bitcoin ETFs experienced net outflows of $487.2 million between October 22 and 27. Analysts believe $80,000 is a critical support level, and if the $81,000-$82,000 range can be reclaimed, Bitcoin could target $84,000-$85,000.
