DCA Stacked BTC
Total BTC accumulated by a monthly Dollar Cost Averaging on horizons of 1y / 3y / 8y. Answers the practical retail question: 'how many sats did consistent buying earn me?'.
What is it?
DCA Stacked BTC plots the hypothetical accumulation of a monthly DCA strategy initiated X years ago and held until today. The metric is exposed against a **fixed monthly budget convention** by the community on-chain pipeline (exact amount not publicly documented upstream - the value is not an absolute in USD invested). **The primary institutional use** is to compare the SHAPE and SLOPE across the three horizons (1 year / 3 years / 8 years) to identify favourable accumulation windows (steep slope in bear market = many BTC per budget unit) versus unfavourable (flat slope in bull market = few BTC per budget unit). **To estimate your personal stack**, use the dedicated backtest calculator (Trinity Backtest Tool, accessible via the Cycles menu) which takes your actual budget as input.
How to read
Each curve represents the cumulative BTC stock for a given time window. The 8-year curve is mechanically higher than 3-year and 1-year curves since it covers a longer period of monthly buys. The slope of a curve translates the accumulation pace at a given instant: steep slope in bear markets (cheaper buys, more BTC accumulated per USD unit) and shallow slope in bull markets (more expensive buys, less BTC per USD unit). Log scale is recommended to visualise the three horizons simultaneously.
Key zones
Slope acceleration of a curve during a bear market identifies a favourable accumulation window. Conversely, slope flattening during a bull market translates the rising cost of each additional BTC. The 8-year curve, smoother, masks sub-period volatility - useful to visualise the cumulative long-term trajectory. The 1-year curve, more volatile, reveals recent favourable accumulation phases.
What to observe
The vertical gap between the three curves translates the total BTC quantity accumulated in each window. This gap is mechanically non-decreasing - an investor never loses accumulated BTC, they stay in the wallet. The local slope of a curve is the sole indicator of accumulation pace. A steeper slope in the last quarter relative to the previous year suggests the market has offered more favourable accumulation conditions over the most recent quarter.
Historical context
BTC inflation of a monthly DCA strategy is mechanically declining - every buy at a price higher than the previous average reduces the average BTC quantity obtained per USD invested. On the 2014-2015, 2018-2019, 2022-2023 bear markets, the slope accelerated significantly: a DCA investor during these phases accumulated proportionally more BTC per USD invested than a DCA investor during surrounding bull phases.
Expert notes
**Cycle-relative metric**: the absolute value depends on an internal on-chain pipeline budget convention - institutional use targets the SHAPE of the curve and the ratio between horizons, not the absolute value. DCA Stack is mathematically complementary to DCA Returns: a high Stack combined with low Return means the investor accumulated many BTC but at relatively expensive prices (low latent profit). A low Stack combined with high Return means the investor accumulated few BTC but at very low prices (large latent profit per BTC). Both metrics must be read jointly to evaluate the quality of a DCA strategy. Stack completely ignores entry price - it is a pure quantity measure.
Common mistakes to avoid
Believing that a high DCA Stack guarantees significant profit is false. If accumulation happened mostly at an average price higher than the current price, the portfolio can be at a loss despite a very high Stack. Conversely, a low Stack (recent DCA) can represent a significant profit if accumulation happened at a cycle trough. Always cross-reference DCA Stack with DCA Returns for a complete view.
