A long-term Bitcoin trend signal has flipped positive, and history says that has been very good news for holders.

• The 21-period moving average has crossed above the 377-period one, a rare long-term signal.
• This cross has pointed higher 78% of the time it has fired.
• When it works, the typical gain a year later has been over 100%.
• It is treated as a stronger signal than the better-known golden cross, which uses much shorter averages.

Outlook: If the pattern holds as it has before, Bitcoin is set up for a strong year rather than a quick move.
