Improving the DCA strategy, Bitcoin example.

Traditional DCA buys a fixed dollar amount on a schedule no matter what the market is doing. That’s simple, but it treats a euphoric top the same as a panic bottom. If you imagine “risk” on a 0 - 100 scale (0 = coolest, 100 = hottest), classic DCA keeps buying from 0 through 100 with the same size. In my 2022-now backtest, that blind approach landed about 18%/year, respectable, but indifferent to conditions.

Vanila DCA

Now add one simple rule: set a “balance point” at risk 50 and pause buys when risk >= 50. Same constant size below 50, zero above it. During the same period, that tiny bit of risk-awareness lifted results to roughly 25%/year, and it actually invested ~$5k less than the blind DCA because we skipped the hotter stretches.

Adding Stop buying rule

Next, fix that under-investment, nudge sizing with the risk bands. Example “linear ramp”:

• risk < 50 -> buy $100
• risk < 40 -> buy $200
• risk < 30 -> buy $300, and so on.

In the same timeframe, that “buy more when cooler” rule pushed results to about 31%/year. Capital is allocated where risk is lower, so each dollar works harder.

Adding Linear Ramp

Additional, If you are aggressive Bitcoin addicted, let's run the test "exponential ramp", double down each step:

• risk < 50 -> $100
• risk < 40 -> $200
• risk < 30 -> $400, etc.

That pushes total invested higher (much more invested amount than vanilla DCA ) and lifted the backtest to ~34% per year.The trade-off is obvious: better returns, higher capital commitment, and you must manage cash so you’re never forced to stop buying at the best moments. The % of yearly return will be much higher when Bitcoin moves up.

Changing to Exponential ramp

A few takeaways:

• Process beats prediction. Small rules, pause when hot, ramp when cool, compound edge without needing to call tops.
• Capital discipline matters. If you ramp, plan your budget so “cooler” bands actually have dollars waiting.
• Risk bands are a dial, not an oracle. They tell you how aggressively to participate, not whether the market will moon.

For a quick sanity check, I also tested a simple moving-average variant: use a 200D MA as a balance point and reduce/stop buys when price is extended well above it. Even that basic rule came out slightly better return % per year than blind DCA, same idea, fewer hot-zone buys.

This is how the ideal of improving DCA with a transparent, explainable risk measure on Bitcoin: start with constant DCA, add a pause above 50, then ramp sizing as risk cools. Either Bitcoin chops or trends, leverage the time and rules, the longer you stay, the stricter rules you have, the more BTC you accumulate.

Not financial advice. I’m sharing backtest results for the 2022 - now window to illustrate the logic, not to promise outcomes.
