According to the source, BTC dropped below $100,000 during the latest session as spot prices weakened across risk assets (source: Coinbase BTC-USD price feed). The move is attributed to a stronger U.S. dollar as the ICE U.S. Dollar Index advanced, tightening financial conditions from higher U.S. Treasury yields, net outflows from U.S. spot Bitcoin ETFs, and elevated long-side liquidations alongside funding turning negative and futures basis compression (sources: ICE Data Indices for DXY; U.S. Department of the Treasury daily yield curve; Farside Investors ETF flow tracker; Coinglass liquidations dashboard; CME Group futures data). For trading, participants are focusing on daily ETF flow direction, USD strength versus risk sentiment, and derivatives positioning to gauge continuation or mean-reversion risk (sources: Farside Investors; ICE Data Indices; Coinglass; CME Group).
