What happens to Bitcoin Cash after Bitcoin jumps 10% in a day?
Since 2019, Bitcoin Cash has shown Bitcoin jumps 10% in a day 17 times. In the 17 cases old enough to score, the price was higher 7 days later 47% of the time, with a median move of −0.6%. On an ordinary day the median 7-day move for BCH is −0.2%.
No better than chance9
Once you allow for how many studies were run, a gap this large is luck about 98% of the time, so this signal has told you nothing reliable about the following week.
On the day itself, the median move was +8.9% for BCH against +11.2% for Bitcoin. BCH had the worse day 65% of the time. The figures below start from BCH's close on that day.
By holding period
| After | Cases | Higher | Median move | Middle half | Ordinary median | Gap | By luck | Proof score |
|---|---|---|---|---|---|---|---|---|
| 1 day | 17 | 47% | −0.1% | −3.9% to +3.3% | 0.0% | −0.1% | 98% | 9 |
| 3 days | 17 | 47% | −2.8% | −6.5% to +3.7% | −0.2% | −2.6% | 44% | 19 |
| 7 days | 17 | 47% | −0.6% | −6.4% to +7.8% | −0.2% | −0.4% | 98% | 9 |
| 14 days | 17 | 53% | +1.2% | −7.3% to +12.9% | −0.5% | +1.8% | 93% | 11 |
| 30 days | 17 | 47% | −7.5% | −14.6% to +12.1% | +0.1% | −7.6% | 70% | 42 |
“Ordinary median” is the median move of BCH over the same number of days starting from any day. “Gap” is the signal's median minus the ordinary one. “By luck” is how often a gap at least that large comes from randomly chosen days, corrected for the 3,572 studies run at each holding period (for this study taken alone: 89%).
Holding it for 7 days
Dips and best points use each day's low and high, measured from the close on the signal day. Costs assume 0.3% for a round trip: a 0.1% exchange fee each way and 0.05% slippage each way.
Did it hold up over time?
Splitting the cases by date: in the earlier 10 the gap over 7 days was +4.7%, and in the later 7 it was −5.1%. The direction changed, which is what a pattern produced by chance tends to do.

The rule
Bitcoin's daily close is at least 10% above its previous close. The outcome is measured on this coin, from its own close that day.
Occurrences closer than 7 days to the previous one are not counted again. The signal is confirmed at the daily close (00:00 UTC) and returns are measured from that close. Full method.
