No clear edge 1, 7 or 30 days later: no 95% range clears the same coins' ordinary days with both halves of history agreeing (206 cases). Measured on Bitcoin's own price. Coin by coin, it is a likely driver on 34 coins.

These odds in plain words

as of · counted from every past case of this pattern

Bitcoin difficulty adjustments (Bitcoin's move) with BTC below its 50-day average: 89 of the 89 past cases on record have a measured next-day move, and 38 of those 89 closed higher — a base rate of 43%, with a 90% range of 34% to 51%, counted as of Oct 19, 2026.

  • By day 30, 50 of the 89 cases measured that far were still above the close before the event (56%).
  • The typical day-30 move was +1.8%, the best +46.3% and the worst −30.6%.
  • Against Bitcoin over the same 30-day windows, the typical case ran 0.0% vs BTC and beat it in 0.0% of 89 comparable cases.
  • Recent-cases check: older cases (the first 60%) were higher the next day 49% of the time and newer cases (the last 40%) 33% of the time, so the count stayed on the same side on the newest cases.

How this is counted

How these odds are counted

as of · methodology

This page is a count of 89 measured past cases, not advice. A pattern is a set of conditions on an event and its token at the time (BTC regime), kept once 8 of its cases have a measured next-day move.

  • Every share comes with a 90% range (a Wilson interval).
  • Patterns with 20 or more measured cases are counted again on their older 60% and newest 40% of cases, and a pattern whose side flips (its share crosses 50%) is flagged as flipped.
  • Past patterns can stop working.

The full method — how patterns are built, the 90% ranges, the recent-cases check and the minimum number of cases — is on the methodology page.

Questions

Questions about this pattern

as of · answers generated from this count

What does the 43% figure on this page mean?
  • It is a base rate: 38 of the 89 measured past cases of bitcoin difficulty adjustments (Bitcoin's move) with BTC below its 50-day average closed above the close before the event one day later, counted as of Oct 19, 2026.
  • It is a count of the past, with a 90% range of 34% to 51% — not advice, and past patterns can stop working.
How is a case measured?
  • Each case compares the last daily UTC close before the event with the closes 1 and 30 days after it, exactly as on every event list on this site.
  • The vs-BTC column subtracts Bitcoin's move over the same 30 days.
Why does this pattern exist and others not?
  • A pattern is kept only once at least 8 past cases have a measured next-day move.
  • This one has 89.
  • Narrower combinations of the same conditions with fewer than 8 cases are left out, and their cases stay counted in the broader pattern.
What does the recent-cases check say here?
  • The record was split 60/40 by date: older cases (the first 60%) were higher the next day 49% of the time and newer cases (the last 40%) 33% of the time.
  • A flipped flag means the older and newer halves of the record disagree about the direction.
Where do the 89 cases come from?
  • From this site's own event history: every Bitcoin difficulty adjustment with a known date whose token met the pattern's conditions at the time, with its moves measured from CoinPaprika daily closes.
  • The full list, with dates, is on this page.
