Bitcoin's August golden cross is being read as a bullish setup, with the winning historical pattern pointing to a rally lasting into early December.

• Golden crosses that fail tend to top out on day three, up only a few percent, then fade.
• The typical successful cross keeps making new highs for about 110 days.
• Bitcoin's latest cross landed on August 19, putting the 110-day mark around December 7.
• The early-days behavior is the tell: no quick stall means the move has room to run.

Outlook: The next few weeks decide it — an early rollover would mark this as a failed cross, while continued highs point toward a run into December.
