Bitcoin (BTC) has surged 21% over the past 30 days, reclaiming the $81,000 level for the first time since January. Now, the largest cryptocurrency faces a critical test that could determine its next major move.

Technical analyst Ali Martinez highlights a bullish MACD crossover on Bitcoin's weekly chart that occurred on April 13. Historically, similar signals preceded rallies of 147% in 2023, 75% in 2024, and 35% in 2025. Martinez notes BTC is approaching the 200-day simple moving average near $83,000-a psychological and structural barrier. A daily close above this level, he argues, could open the door to $89,000, with a secondary target near $94,000.

Market expert Sam Daodu adds that Bitcoin has reclaimed the Bull Market Support Band at $79,000 for the first time in six months. When BTC previously reclaimed this band after extended periods below it, rallies of 50% or more followed within months. Applying that pattern, Daodu sees a potential path toward $121,000, just below the all-time high near $126,000 from October 2025.

Despite these bullish signals, analysts caution that Bitcoin must hold above these levels to sustain momentum. The question remains whether the surge above $81,000 marks the start of a new leg higher or precedes another correction.
