$100 Monthly XRP DCA Backtest: January 2021 to July 2026

By XORA · Published 2026-08-17

Investing $100 in XRP on the first day of every month from January 2021 through July 2026 put $6,700 to work, acquired 9,896.20606117 XRP, and finished July worth $10,495.52. That is a $3,795.52 gain, or 56.65%, but a same-capital lump sum invested on January 1, 2021 finished at $32,353.29 because the starting price was exceptionally low. This is a historical calculation, not a forecast.

The direct result

The backtest makes 67 equal purchases at the Bitstamp XRP/USD daily opening price at 00:00 UTC on the first calendar day of each month. January 2021 through December 2025 contributes $1,200 per year. January through July 2026 adds $700. The final valuation uses the July 31, 2026 daily close of $1.06056, the latest complete calendar month available when this analysis was produced.

The lump sum ended $21,857.76 ahead and held 3.08 times as much XRP. That does not prove lump sum will always win. It shows what happens when the comparison begins at $0.21963 and much of the later DCA capital buys above that price.

This is a capital-timing comparison, not a verdict on saving habits. The lump-sum investor must possess $6,700 in January 2021 and accept immediate exposure to the entire position. The DCA investor needs only $100 each month and keeps future contributions outside XRP until their scheduled purchase dates. If the $6,700 did not exist at the start, the lump sum was never an available choice. If it did exist, delaying deployment created cash drag during rising periods but reduced early exposure during falling periods. Those different constraints matter as much as the ending return.

Exact, reproducible methodology

1. Market: Bitstamp XRP/USD, so there is no stablecoin conversion assumption.
2. Purchase rule: buy exactly $100 at each first calendar day's daily candle open, beginning 2021-01-01 and ending 2026-07-01.
3. Precision: preserve the published decimal prices and fractional XRP throughout the calculation; round only displayed summaries.
4. Final mark: value every acquired XRP at the 2026-07-31 daily close, $1.06056.
5. Lump sum: invest the same total $6,700 at the 2021-01-01 open, $0.21963. This assumes the full amount existed on day one.

DCA XRP = Σ ($100 ÷ each monthly opening price)

Lump-sum XRP = $6,700 ÷ $0.21963

Final value = XRP acquired × $1.06056

The candle data come from Bitstamp's public OHLC API documentation. Because the endpoint caps one response at 1,000 candles, reproduce the complete series with three 86,400-second requests beginning at Unix timestamps 1609459200, 1695859200, and 1782259200. Concatenate the responses, select rows whose UTC date is the first of the month, and sum the formula above. Use the July 31 close rather than August data because August 2026 was incomplete.

Every monthly purchase price

The table below is the calculation's audit trail. Each cell is the exact USD opening price used for that month's $100 purchase. A blank 2026 cell means no purchase was included.

Where the DCA acquired its XRP

The 2022 and 2023 contributions did the heaviest unit accumulation. Each $1,200 cohort acquired about 2,480 XRP at an average cost near $0.484. By contrast, the 2025 cohort acquired only 502.45343 XRP because its average cost was $2.38828. Equal dollars automatically bought more units when XRP was cheaper and fewer when it was expensive.

The break-even entry-price test

There is a compact way to explain the outcome. A same-capital lump sum acquires more units whenever its entry price is below the completed DCA program's average cost. Here, that break-even price was $0.67703. The actual January 2021 entry was $0.21963, or 67.56% below the threshold. Therefore the lump sum acquired 30,505.85 XRP while DCA acquired 9,896.21.

The final valuation price cancels out when comparing XRP units: both strategies hold the same asset on the same date. That makes $0.67703 a useful path summary. A hypothetical $6,700 lump sum entered above that price would have acquired fewer than 9,896.21 XRP and lost this unit comparison. Entered below it, as happened here, it wins. The threshold describes this completed path only; it cannot be known before all future monthly purchase prices are observed.

What this backtest does not prove

This result cannot tell an investor what the next 67 months will do. Moving the starting date can reverse a lump-sum comparison, and using a salary-funded DCA instead of cash already available changes the decision itself. Bitstamp prices can also differ slightly from another exchange at the same second.

The calculation excludes trading fees, bid-ask spread, slippage, taxes, yield, and custody costs. It assumes every order fills exactly at the daily open and fractional XRP is available. Those simplifying choices make the arithmetic auditable, but they make the result a model rather than a brokerage statement.

The U.S. Investor.gov glossary defines dollar-cost averaging as investing equal portions at regular intervals regardless of market movement. That process reduces dependence on one entry timestamp; it does not guarantee a gain or make XRP less volatile. Its crypto custody bulletin also explains risks around both self-custody and third-party custody. Never invest assets you cannot afford to lose.

For the operational process rather than the historical test, see how to dollar-cost average XRP. To separate asset accumulation from potential earnings, use the XRP yield calculator, read how XRP yield works, and review the platform's security and custody model.

Put accumulated XRP to work

DCA answers when and how capital entered XRP; it does not answer what the accumulated XRP does afterward. Any yield decision should keep market performance, native XRP yield, estimated reward value, custody, and platform risk separate.

Put your XRP to work at xora.finance for up to 22% instead of leaving it idle on an exchange. That is up to 22% APY value (15% native XRP yield, treasury-subsidised during a disclosed bootstrap, plus estimated XORA reward value). It is variable, never guaranteed, and not risk-free.
