Dollar-cost averaging (DCA)
Dollar-cost averaging (DCA) is an investing method that consists of buying a fixed amount of an asset at regular intervals, for example $100 of bitcoin every month, whatever the price, to spread purchases over time and reduce the impact of volatility.
Also called DCA, Recurring buy, Periodic investing, Averaging in

Dollar-cost averaging (DCA) means investing the same amount of money at regular intervals, regardless of the price. Instead of putting $1,200 into crypto in one go, you buy $100 every month for a year. Many exchanges offer this as a “recurring buy” feature. DCA does not try to guess the best moment to buy; it spreads the risk of buying at a bad time.
How DCA works
You choose three things: the asset, the amount and the frequency (weekly, every two weeks, monthly). The platform then buys automatically on each date. When the price is high, your fixed amount buys fewer units; when it is low, it buys more. Over time, your average purchase price is smoothed out. Our guide on how to buy crypto explains how to set up a first purchase.
A worked example
You invest $100 a month in a coin for four months. The price is $50, then $40, then $25, then $50.
- Month 1: $100 ÷ $50 = 2 coins
- Month 2: $100 ÷ $40 = 2.5 coins
- Month 3: $100 ÷ $25 = 4 coins
- Month 4: $100 ÷ $50 = 2 coins
You spent $400 and own 10.5 coins, an average cost of about $38.10 per coin, while the average of the four prices was $41.25. At the final price of $50, your position is worth $525. Had you invested $400 at once in month 1, you would hold 8 coins worth $400. In a market that only goes up, a lump sum would have done better; DCA shines when prices swing.
Why DCA matters
Crypto prices are very volatile, and few people manage to buy at the bottom. DCA removes the pressure of timing the market and limits emotional decisions such as buying after a big rise or selling in panic. It also fits a monthly budget. Long-term holders of Bitcoin often use it.
Risks and limits
- DCA does not protect against losses: if an asset falls steadily or goes to zero, you keep buying a losing asset.
- Fees matter. Small, frequent purchases can be expensive on platforms with a minimum fee per order; compare costs with our guide on choosing a crypto exchange.
- In a strong uptrend, investing everything at once usually gives a better result.
- DCA is a method, not a recommendation of what to buy. Only invest money you can afford to lose and consider moving long-term holdings to your own wallet.
