Someone who invested $100 every week in Bitcoin starting January 1, 2020 — without missing a single week, without trying to time the market, without any special knowledge — would have invested $31,200 in total by the end of 2025. That $31,200 would be worth approximately $96,400 today. A 209% return, achieved by doing almost nothing.
Dollar Cost Averaging (DCA) is the practice of investing a fixed amount at regular intervals regardless of price. This guide covers exactly how DCA works, what the real backtested numbers look like, how weekly compares to monthly investing, and the five mistakes that turn a solid DCA strategy into an underperforming one. Use the free crypto DCA calculator above to run your own numbers instantly.
Does Crypto DCA Actually Work? The Short Answer
Yes — with two conditions. It works best on assets with long-term upward trajectory, and it works best when you do not stop during crashes.
- When prices are high — your fixed amount buys fewer coins.
- When prices are low — your fixed amount buys more coins. This is where DCA does its real work.
- Over time — your average cost per coin is lower than a lump sum at any random point.
The crypto DCA calculator backtests any weekly or monthly amount across Bitcoin, Ethereum, and other coins from any start date.
Real DCA Backtested Results: Bitcoin
| Start Date | Total Invested | Portfolio Value (Jul 2026) | Return |
|---|---|---|---|
| January 2020 | $33,800 | $96,400 | +185% |
| January 2021 | $28,600 | $41,200 | +44% |
| January 2022 | $23,400 | $29,800 | +27% |
| January 2023 | $18,200 | $31,500 | +73% |
Someone who started DCA in January 2021 and kept going through the entire 2022 bear market still ended up 44% ahead by mid-2026. Run your own numbers with the free DCA calculator.
Weekly vs Monthly DCA: Which Performs Better?
| Strategy | Total Invested (3 years) | Portfolio Value (Jan 2026) | Return |
|---|---|---|---|
| $100 weekly | $15,600 | $21,840 | +40% |
| $400 monthly | $14,400 | $19,440 | +35% |
Weekly edges monthly by about 5 percentage points over a three-year period. The reason is simple: more frequent purchases mean more exposure during short-lived price dips. Pick the interval that fits your pay cycle and automate it completely — the key variable is consistency, not precision.
Which Cryptocurrencies Are Best for DCA?
Bitcoin (BTC) — the strongest DCA case of any crypto asset. Longest track record, deepest liquidity, and has recovered from every multi-year bear market in its history.
Ethereum (ETH) — solid DCA candidate. Ethereum's margin over Bitcoin has narrowed since the 2022 merge but the long-term fundamentals remain strong.
Solana (SOL) — high risk, high reward. Suitable only for investors who can psychologically hold through 90%+ drawdowns without selling.
Altcoins below top 20 — generally not suitable for DCA. Most do not recover meaningfully from major bear markets and carry permanent-loss risk.

How to Calculate Your DCA Average Cost Basis
Average Cost Basis = Total Amount Invested ÷ Total Coins Purchased
| Month | Amount | BTC Price | BTC Purchased |
|---|---|---|---|
| January | $200 | $42,000 | 0.00476 |
| February | $200 | $38,000 | 0.00526 |
| March | $200 | $35,000 | 0.00571 |
| April | $200 | $29,000 | 0.00690 |
| May | $200 | $31,000 | 0.00645 |
| June | $200 | $36,000 | 0.00556 |
$1,200 ÷ 0.03464 BTC = $34,641 average cost basis. At $95,000 BTC the portfolio is worth $3,291 — a 174% return. Check your exact break-even price at any point in the DCA journey.
5 DCA Mistakes That Kill Your Returns
1. Stopping during crashes
The 2022 bear market felt catastrophic. Those who kept buying through it have the best 2026 returns of any cohort.
2. DCA-ing into too many assets
One to three assets maximum. Spreading across 10 coins is dilution disguised as diversification.
3. Not automating purchases
Manual DCA fails because humans are emotional. Automated DCA removes the decision entirely.
4. Ignoring the tax implications of many small lots
156 separate tax lots from three years of weekly DCA creates real accounting complexity. Use the crypto tax estimator to stay ahead of it.
5. Setting an unsustainable amount
$50 weekly sustained for five years beats $500 weekly abandoned after two months. Every time.
