Bitcoin's relationships with gold, the dollar, interest rates and the rest of crypto — measured, including the ones that fail under control and the one that fails exactly when it matters.
The most reliable thing about bitcoin's price is that ether, solana and XRP move with it: hourly correlations of +0.838, +0.790 and +0.707. But Apex tested which one drives, and the answer was not bitcoin. Holding bitcoin constant, solana and XRP still correlate at +0.506. Holding ether constant, bitcoin's link to solana falls from +0.790 to +0.315.
There is one common crypto factor that all four hang on, and ether measures it better than bitcoin does. «Bitcoin leads the market» is the wrong description of a real phenomenon.
On 60-day daily data bitcoin and gold correlate at +0.58 — a five-year high, and the number behind every «digital gold» headline of 2026. On hourly data over the same period it is +0.150, the 53rd percentile. Both are correct: bitcoin and gold drift together over weeks but do not react together within a day. Detail on bitcoin and gold.
Bitcoin's correlation with the 10-year real interest rate is −0.076 across 1,243 days. The Nasdaq's is −0.165. On the axis where a monetary asset should look like gold, bitcoin looks less like gold than the technology index does.
Its dollar link tells the same story: −0.114 raw, falling to −0.034 once gold is held constant. Bitcoin has no independent dollar relationship — it borrows gold's. See bitcoin and the dollar.
Over two days in September 2026 Apex tested nine separate approaches to anticipating bitcoin's direction: using ether as the input instead of bitcoin, conditioning on move size, order-book walls, liquidation levels, the hour before the Nasdaq opens, a fall since Sunday, funding rate, holding time, and taking profit earlier. Every one came out at a coin flip. Lead–lag has now been tested 38 times across instruments and peaks at zero offset every time.
All numbers were measured and published in Apex’s own record at the time stated. They describe the past under stated conditions and promise nothing about the future. What moves markets · Relationships · Research
