Dollar-cost averaging: buying regularly instead of timing the market
Investing a fixed amount at regular intervals: how it smooths the entry price, and what it does not protect against.
Dollar-cost averaging (DCA) means buying an asset for the same amount of money at regular intervals — for example, every week — regardless of the price.
How it smooths the price
When the price is low, the fixed amount buys more units; when it is high, it buys fewer. Over time the average cost per unit is pulled towards the average price of the period.
A simple illustration: 100 USDT is used at a price of 10 (10 units), then at 20 (5 units). The total is 200 USDT for 15 units — an average cost of about 13.3, lower than the simple average of the two prices (15).
Why people use it
- It removes the need to guess the "perfect" moment.
- It reduces the emotional pressure of one big decision.
- It turns investing into a routine.
What it does not do
- It does not prevent losses. If an asset falls and never recovers, regular buying only adds to the loss.
- It does not choose the asset for you.
- In a market that rises steadily, buying everything at the start would have been cheaper.
- Fees on many small purchases add up.
Discipline is the main ingredient
DCA works only if the plan continues through falling markets — which is exactly when it feels hardest. The amount should be one you can afford to lose.
