Bitcoin 2-year MA multiplier chart: the 2-year moving average as a buy zone and 5× that average as a sell zone — one line for each side of the cycle. Updated daily.
Log scale. Both lines are simple moving averages of the daily close.
buy zone: price < SMA(730) · sell zone: price > 5 × SMA(730)
Two lines derived from a 2-year (730-day) simple moving average: the average itself and five times it. The indicator was designed as a long-term investor's timing tool — accumulate when price dips below the average, take profit when it exceeds the 5× line.
Price crossed above the 5× line at the 2013, 2017 and (briefly) 2021 tops and below the 2-year MA at the 2015, 2018–19 and 2022 bottoms. The 5× band has become harder to reach as cycles mature.
As of Oct 19, 2026 the 2-year moving average is $89,159 and 5× it is $445,797; Bitcoin closed at $82,541, below the average (buy zone).
As a slow timing tool for long-term holders: accumulate when price falls under the 2-year average, reduce when it rises above five times the average. It gave a handful of signals per cycle in the past.
It has been harder to reach each cycle — 2021 only touched it briefly. If diminishing returns continue, the 5× multiplier may need revising; Coinfuty keeps the original parameters for comparability.
Coinfuty computes every series on this page from daily BTC close prices and public constants — the Bitcoin halving schedule, block subsidy and published regression coefficients. Values refresh nightly (00:20 UTC) and the current day is patched hourly. These are historical, backward-looking indicators; nothing here is investment advice.
