Bitcoin recorded a sharp surge in buying pressure on December 17, triggering a rapid inflow of capital that briefly pushed the flagship cryptocurrency above the $90,000 level. During a roughly 30 minute window, BTC climbed from around $87,000 to a session high just above $90,000 before stabilizing near $89,950 at the time of publication, with the move marking one of the fastest short-term price advances seen in recent weeks.

Trading volume remained elevated during the spike, with 24 hour volume ranging between $34.6 billion and $37.5 billion as volatility increased. The rapid move higher followed a period of consolidation earlier in the session, with Bitcoin trading sideways before aggressive buying emerged. Notably, the breakout briefly lifted the asset above the psychologically important $90,000 threshold before modest profit taking set in. Despite the pullback from intraday highs, Bitcoin held onto most of its gains, suggesting that buyers were willing to absorb selling pressure at elevated levels. The move also pushed Bitcoin’s fully diluted valuation close to $1.88 trillion, while circulating supply remained steady at just under 20 million BTC. Traders should take note that short-term spikes in market capitalization often reflect concentrated buying from large participants rather than gradual retail inflows. While the exact source of the buying pressure remains unclear, the speed of the move suggests coordinated demand entering the market within a narrow time frame.
