BTC: 350-day average × 21

Bitcoin 350-day average × 21 was $1,590,789.58 on 7 Nov 2026 (latest daily value).

The 350-day moving average of the daily BTC close multiplied by 21.

Why use it. One of the golden ratio multiplier's reference levels: how far price has stretched above its long-run average. Earlier cycle tops reached ever lower multiples. How to read it. Price reaching this line means it stands 21× its 350-day average. A reference level, not a forecast; read it on a logarithmic scale with the other multiples.

Calculation. Arithmetic mean of the last 350 daily closes (the current day included), × 21; the line starts once 350 consecutive valid closes exist. This is one line of the chart "Golden Ratio Multiplier"; it is published separately so it can be charted, compared and exported alone. Daily closes are the accepted daily valuation prices: historical closes from The Bitcoin Time Machine (CC BY 4.0) until 3 October 2026, then our own recorded quotes; they stay provisional and revisable. A missing or invalid close leaves every window containing it empty; nothing is interpolated.
