On January 21, 2026, the cryptocurrency market continues its weak and volatile pattern. Bitcoin repeatedly tests support in the $88,000-$90,000 range, while Ethereum battles around the $2,950-$3,000 mark, with market sentiment remaining cautious. Liquidity is relatively active during the European and American trading sessions, but there is a lack of clear directional breakthrough momentum, so attention should be paid to the effectiveness of key support levels. A break below $88,000 (BTC) and $2,900 (ETH) could trigger further corrections; conversely, if a stabilization and rebound occur, resistance levels are around $90,500 and $3,050. Trading suggestions include controlling positions and avoiding high leverage to chase gains or cut losses. #欧美关税风波冲击市场 $BTC $ETH
