Bitcoin slipped 0.5% to around $81,400 on Tuesday, despite U.S. spot Bitcoin ETFs attracting $526.6 million on Monday, their largest daily inflow in nearly a month. The decline was attributed to a broader market downturn, with South Korea’s Kospi index falling 3.73% to its lowest close since April 7, as SK Hynix and Samsung Electronics shares dropped amid renewed concerns over AI spending. Options traders are reportedly seeking downside protection.
