How to Use the Bitcoin DCA Backtest: Step-by-Step Guide
The Bitcoin DCA Backtest lets you see how a recurring Bitcoin investment strategy would have performed in the past using real historical market data. Instead of relying on assumptions or predictions, the tool uses actual Bitcoin prices and compares three investment scenarios:
- Recurring purchases (DCA);
- A lump-sum investment made at the beginning of the selected period;
- Keeping your money in cash without investing.
In this guide, you’ll learn how to configure the backtest settings and correctly interpret the results.
What the Backtest Shows?
This is not a prediction of the future—it is an honest look at the past: “What would have happened if…?”
The tool uses real historical Bitcoin prices for your selected time period and compares three investment scenarios:
- DCA — you invest a fixed amount in Bitcoin at regular intervals (for example, every week or every month).
- Lump-Sum Investment — the entire amount that would have been invested through DCA is invested once at the beginning of the selected period.
- Cash (No Investment) — your money remains in cash without any growth.
This comparison helps you evaluate not only the final outcome but also how each strategy would have performed under different market conditions.
Step 1. Enter the Amount for Each Purchase
Enter the amount you want to invest in each recurring purchase, for example, 100 USD.
This is the amount of each individual investment, not your total budget. The total amount invested is calculated automatically by multiplying the amount of each purchase by the number of purchases made during the selected period.
Step 2. Choose Your Currency
Select USD or EUR.
The selected currency will be used to display:
- The amount of each purchase;
- The total amount invested;
- The final portfolio value.
Step 3. Choose the Purchase Frequency
Select how often you would buy Bitcoin.
- Daily — provides the greatest averaging effect.
- Weekly — one of the most popular DCA schedules.
- Biweekly — convenient if you invest after each paycheck.
- Monthly — the simplest option for long-term investing.
The more frequently you invest, the smoother your average purchase price becomes. However, it also means making more individual transactions (and, in real life, paying more exchange fees, which are not included in this backtest).
Step 4. Select the Date Range
Choose the start date and end date for your backtest.
Historical data is available from April 28, 2013, through yesterday.
This is where the real value of the tool comes in. You can test your strategy under a wide range of market conditions:
- During a prolonged bear market;
- During a strong bull market;
- Over long time periods spanning multiple market cycles.
Tip: Run several backtests using different date ranges. The same investment strategy can produce very different results depending on the time period you choose.
Step 5. Click "Calculate"
Once you click Calculate, the tool will load the historical Bitcoin price data and generate the results for your selected investment scenario.
Chart
The chart shows how the value of each investment scenario changes over your selected time period.
- Orange line — DCA strategy.
- Blue line — Lump-sum investment.
- Gray dashed line — Cash (no investment).
The chart lets you see not only the final outcome but also how each strategy performed through different market cycles, including both bull markets and downturns.
Experiment with Different Scenarios
Don’t stop after just one calculation.
Try changing the start date, purchase frequency, or recurring investment amount, then compare the results.
Experimenting with different scenarios is one of the best ways to understand how time, consistency, and market volatility can affect long-term Bitcoin accumulation.
Key Things to Understand
✅ Exchange fees and spreads are not included in the calculation, so your actual results may differ slightly.
✅ Past performance does not guarantee future results. The backtest only shows how the strategy performed using historical Bitcoin price data.
✅ During long-term bull markets, a lump-sum investment often delivers a higher final return because the entire amount is invested from the very beginning.
✅ During prolonged market declines or periods of high volatility, DCA can reduce the impact of poor market timing by averaging the purchase price over time.
