Why was Bitcoin down on Jul 28, 2026, 4:55 AM UTC?

Bitcoin's modest recent volatility (down 3.11% over 24h, flat in the last hour) appears driven by broader market weakness—the Korean stock market's sharp 10% drop and the U.S. market slide suggest risk-off sentiment flowing into crypto. The pending Fed meeting mentioned in the news could be creating uncertainty, though the immediate price action is minor enough that it's likely a mix of technical selling and macro spillover rather than crypto-specific catalysts.
