Bitcoin rebounded slightly from its overnight lows but remains within the $90,000 range. Analysts believe that gold price movements indicate the dollar's status as a reserve currency is "accelerating its decline," while Bitcoin's performance has been "disappointing, continuing to face selling pressure." Another factor contributing to increased volatility is US President Trump's recent proposal to control Greenland, accompanied by new tariff threats against several European countries. This could make it "difficult to rebuild" Bitcoin's momentum, failing to act as a hedge in a cooling risk appetite environment and instead being traded as a high-beta risk asset, highly sensitive to interest rates, geopolitics, and cross-market volatility. Trump's speech in Davos may set the tone for the market's next move. (CoinDesk)
