Does Bitcoin follow the Nasdaq?
No. BTC cleared its cost 49.2 % of the time, against 50.3 % on an ordinary day — the condition does no better than no condition at all.

When Nasdaq rises on the day, does BTC outperform its baseline over the next 1 day?
A question only means something if it is stated precisely enough to be wrong. This is the form the engine measured.
Since 2020 Bitcoin has been described as a high-beta tech trade: risk appetite lifts both, and fear sinks both. The charts do look alike.
532 signal days since 2020-11-10. On 262 of them BTC rose more than break-even over the next 1 day (49.2%). On an ordinary day the same LONG works 50.3% of the time — so the condition adds -1.1 points.
Typical move on a signal day: -0.07% against +0.04% on an ordinary day. Worst signal day: -14.35%.
Chance: a coin that lands LONG-right 50.3% of the time, flipped 532 times, gives 262 or more hits in about 63% of runs (p = 0.6336). That is not distinguishable from luck.
Consistency: first half of the period 52.6%, second half 45.9% — not both above baseline; one half carries it.
No excess over baseline — more days would not help.
A relationship that only appears in one year is usually that year, not a relationship.
the hit rate over the next 30 signal days falls to the baseline (50.3 %) or below — the relationship disappears out of sample
Stated before the next observation, not after. The page recomputes, so if this stops being true the answer here changes with it.
Change the condition, the asset, the direction or the holding period and measure it against the same six years.
