Bitcoin DCA Backtest — Historical Results 2015-2026

Dollar Cost Averaging (DCA) is the most recommended investment strategy for crypto beginners. The principle is simple: invest a fixed amount at regular intervals, regardless of the price. But is this strategy truly profitable over the long term? We backtested Bitcoin DCA over 11 years of historical data to find out.

This article presents the complete results of our simulation: weekly DCA, monthly DCA, comparison with lump sum investing, bear market impact and multi-coin extension. All data is based on actual Bitcoin prices between January 2015 and March 2026.

1. Backtest methodology

Our simulation uses daily Bitcoin price data (BTC/USD) from January 2015 to March 2026, totaling over 4,000 data points. Here are the parameters:

• Amount invested — EUR 100 per week (weekly DCA) or EUR 400 per month (monthly DCA)
• Frequency — Every Monday for weekly DCA, the 1st of each month for monthly
• Transaction fees — 0.1% per purchase (average fees on major exchanges)
• No selling — Pure accumulation strategy (buy and hold)
• Price source — Historical prices from CoinGecko/Binance, daily closing price

For the lump sum comparison, we simulate a single investment of the total amount (EUR 100 x 52 weeks x number of years) on the first day of the period. This represents the scenario where the investor deploys all capital at once.

2. Weekly DCA results 2015-2026

Here are the results of a EUR 100 per week DCA started at different dates, all measured as of March 1, 2026:

The conclusion is clear: regardless of the start date, weekly Bitcoin DCA is profitable. Even investors who started at the peak (November 2021, BTC at USD 69,000) show a return of +130% by March 2026.

The key to DCA is consistency. By buying during downturns (2022 bear market with BTC under USD 20,000), you accumulate more BTC at lower cost, which amplifies gains during the recovery.

3. Monthly vs weekly DCA

Which frequency should you choose? We compared weekly DCA (EUR 100/week) and monthly DCA (EUR 400/month) over the 2019-2026 period, with an identical total investment of ~EUR 37,400:

• Weekly DCA — Final value: EUR 298,000, ROI: +697%
• Monthly DCA — Final value: EUR 289,000, ROI: +673%
• Difference — Weekly DCA outperforms by ~3% on average

The difference is marginal. Weekly DCA offers a slight edge thanks to better price averaging, but monthly DCA is simpler to set up (automatic transfer on the 1st of each month). In practice, consistency matters more than frequency.

Some investors experiment with bi-weekly DCA (EUR 200 every two weeks) which offers a compromise between smoothing and simplicity. Results are nearly identical to weekly DCA over the tested periods.

4. DCA vs Lump Sum: the great debate

Lump sum investing is often presented as statistically superior to DCA in traditional markets. What about Bitcoin?

We simulated a EUR 37,400 lump sum investment on January 1, 2019 (BTC at ~USD 3,700) vs a EUR 100/week DCA over the same period:

• Lump sum (Jan 2019) — Value in March 2026: ~EUR 876,000, ROI: +2,242%
• Weekly DCA (2019-2026) — Value: EUR 298,000, ROI: +697%

Over this period, lump sum clearly wins. But beware: this result is biased because January 2019 was a market bottom. If we take November 2021 (ATH at USD 69,000) as the lump sum date:

• Lump sum (Nov 2021) — Value in March 2026: ~EUR 47,000, ROI: +26% (on EUR 22,800)
• Weekly DCA (Nov 2021-March 2026) — Value: EUR 52,400, ROI: +130%

In this scenario, DCA massively outperforms lump sum. The reason: DCA allows you to buy at low prices during the 2022 bear market, while lump sum remains locked at the high entry price.

Conclusion: lump sum wins if you are lucky enough to enter at the bottom. DCA wins if you enter at the top or during uncertainty. Since nobody can predict the market, DCA is the safest and most reliable strategy for the majority of investors.

5. Bear market impact on DCA

Bear markets are DCA's best friend. Here is how major downturns impacted DCA investors:

2018 bear market (BTC -84%)

Bitcoin dropped from USD 19,800 in December 2017 to USD 3,200 in December 2018. A DCA investor who started in January 2018 with EUR 100/week was down -60% by the end of 2018. But by continuing their DCA, they were up +150% by November 2020, and +1,200% by November 2021.

2022 bear market (BTC -77%)

Bitcoin dropped from USD 69,000 in November 2021 to USD 15,500 in November 2022. A DCA investor who started in November 2021 was down -55% by the end of 2022. By March 2026, they show an ROI of +130%.

The lesson is clear: bear markets are accumulation periods. Each week, your DCA buys more BTC for the same euro amount. When the market recovers, those BTC accumulated at low prices significantly boost your overall return.

The most common mistake is stopping your DCA during a bear market out of fear. The data shows you should do the exact opposite: continue, or even increase your DCA during downturns.

6. Multi-coin DCA: Bitcoin vs Ethereum vs altcoins

DCA is not limited to Bitcoin. We compared EUR 100 weekly DCA across three different strategies (2019-2026):

Multi-coin diversification improves overall returns. The 60/30/10 strategy (Bitcoin/Ethereum/Solana) shows the best returns over this period, thanks to Solana's exceptional performance since 2023.

However, altcoins are more volatile and risky. Solana lost 96% of its value in 2022 (from USD 260 to USD 8). Multi-coin DCA requires strong conviction and high risk tolerance. Bitcoin remains the safest choice for long-term DCA.

7. Best entry strategies

Beyond classic DCA, some investors use variants to optimize their entry point:

• Value DCA — Invest more when the price is below the 200-day moving average, less when above. Our backtest shows a +15% gain over classic DCA on 2019-2026
• Fear & Greed DCA — Invest double when the Fear & Greed Index is in the "Extreme Fear" zone (below 20). +12% gain over classic DCA
• RSI DCA — Invest double when the daily RSI-14 is below 30 (oversold). +8% gain over classic DCA
• DCA + profit taking — Take 10% profit when portfolio exceeds +100% ROI, then reinvest via DCA. Reduces volatility but decreases final return by ~20%

These advanced strategies require active monitoring and tools like the technical indicators in KRYPTFOLIO (RSI, SMA, Fear & Greed). For the majority of investors, classic unmodified DCA remains the best option due to its simplicity of execution.

8. How to set up automated DCA

Here are the steps to start a Bitcoin DCA today:

• Choose an exchange — Binance, Kraken and Coinbase all offer automatic recurring purchases
• Define the amount and frequency — Start with an amount you can invest stress-free, even EUR 25/week
• Configure recurring purchase — On Binance: Menu > Recurring Buy. On Kraken: Autobuy. Set it and forget it
• Track with KRYPTFOLIO — Connect your exchange to track your DCA in real time, calculate your average purchase price and simulate future scenarios

The advantage of DCA is that it eliminates the stress of market timing. You no longer need to ask yourself if it is the right time to buy. The answer is always: now, regularly.

9. Backtest limitations

It is important to keep in mind the limitations of this analysis:

• Past performance does not guarantee future results
• Bitcoin only has 15 years of history — the sample is limited
• Exchange fees vary and can impact the final return
• Inflation is not factored into the ROI calculations
• The risk of total loss (Bitcoin collapsing to 0) is non-zero, although it decreases with adoption

That said, DCA remains the most proven strategy for investing in a volatile asset like Bitcoin. It minimizes the risk of bad timing and allows you to benefit from the long-term upward trend.
