Bitcoin climbed from weeks of trading below $65,000 to nearly $80,000, gaining about $15,000 in approximately 48 hours after monetary changes in the US were announced by the Treasury Department. The move shifted market sentiment sharply, with the Fear and Greed Index (market sentiment gauge) reaching 71 today and 72 yesterday. Greed has dominated on only one other occasion since the start of the year, and the current readings are the highest since October 2025. The surge recalls Warren Buffett’s advice to be fearful when others are greedy, while also evoking October 10, 2025, when Bitcoin and the broader market suffered double-digit losses and liquidations exceeded $19 billion in less than 24 hours. The index has not yet entered extreme greed territory, but the increase could be an early warning of a trend reversal.
