Same dollar amount. Regular intervals.
Dollar-cost averaging (DCA) means investing a fixed amount on a regular schedule, whether prices rise or fall. For example, someone might buy $25 of Bitcoin each week. When the price is lower, that $25 buys more Bitcoin; when it is higher, it buys less.
DCA is a way to organize purchases, not a way to identify the next winning investment. The idea also applies beyond crypto.
How to dollar-cost average
- Set an affordable budget. Keep bills, emergency savings, and money needed soon separate. For crypto, use only money you can afford to lose.
- Research what you are buying. Understand the asset, its purpose, and its risks. A low price alone does not make a token a good investment.
- Choose an amount and a schedule. For example, $25 every Friday or $50 each month. These are illustrations, not recommended amounts.
- Check the total cost. Review trading fees, price spreads, minimum purchases, and any recurring-buy charges. Small purchases can be expensive if each carries a fixed fee.
- Make scheduled purchases. Buy manually or use a recurring-buy feature if your provider offers one. Check the asset, amount, frequency, funding method, and fees before confirming.
- Keep records and review periodically. Track spending, fees, and units purchased. Revisit your budget and the reasons for owning the asset if circumstances change.

What could $25 a week buy?
This simplified example uses an imaginary coin. Prices are made up, fees are excluded, and the figures are not a forecast.
| Week | Coin price | You spend | Coins bought |
|---|---|---|---|
| 1 | $10.00 | $25.00 | 2.50 |
| 2 | $5.00 | $25.00 | 5.00 |
| 3 | $12.50 | $25.00 | 2.00 |
| 4 | $10.00 | $25.00 | 2.50 |
| Total | $100.00 | 12.00 | |
Average purchase cost: about $8.33 per coin.
$100 spent ÷ 12 coins purchased = $8.33, before fees.
Notice how the same $25 bought twice as many coins at $5 as it did at $10. Your average cost is total spending divided by total coins—not the simple average of the four quoted prices.
If the coin later falls to $4, those 12 coins would be worth $48. A consistent buying schedule can still result in a substantial loss.
Potential benefits
- A manageable habit. A planned contribution can fit a regular budget.
- Less pressure to time the market. Purchase dates are decided in advance.
- Less emotional decision-making. A schedule can reduce the urge to chase a rally or react to a frightening headline.
- Purchases spread over time. An initial pool of money is not exposed to one entry price all at once.
Can you keep buying as prices rise?
Yes. DCA follows the schedule in both directions. If a later purchase is above your existing average cost, your average cost rises; a purchase below it lowers that average.
Keeping the same dollar amount as prices rise is different from increasing your spending to chase a rally. Stay within your planned budget and review whether the investment still fits your goals.
A useful tool, with real limits.
DCA cannot guarantee a profit, prevent losses, or make a failing asset recover. Transaction costs can add up. If prices keep rising, investing an available lump sum earlier could perform better.
A series of limit orders at lower prices is a different approach: those orders depend on the market reaching a price, while DCA depends on a schedule.
Crypto can lose most or all of its value. Protecting your account and understanding custody remain essential, however you buy.
