A big bullish monthly candle has shown up on Bitcoin's chart, a setup that has only happened three times in the past decade — and each time it was followed by strong gains, which is good news for holders.

• The pattern is a large bullish engulfing candle, meaning buyers wiped out the previous period's losses and then some.
• Only three earlier cases exist in 10 years of Bitcoin trading history.
• Each time, the next 100 days or so brought a similar upward push.
• The clearest example was October 2024, when Bitcoin broke out of a mid-cycle pullback and ran up nearly 60% within about 105 days before climbing further.

Outlook: If the pattern holds true again, the next three to four months point higher for Bitcoin.
