Bitcoin is tracking ahead of its usual pace after a bullish technical signal, which is good news for holders.

• The silver cross — a faster-moving signal than the better-known golden cross — fired 43 days ago.
• Bitcoin is up 17% since then, well ahead of the 9-10% typical at this stage.
• This signal has fired more often over the past decade, so its track record is broader and it flags moves earlier.
• Past runs show gains tend to accelerate again around day 90, still 45 days out.

Outlook: If the pattern holds, the next leg higher arrives in about six weeks.
