Dollar cost averaging, often shortened to DCA, is a way to invest the same amount of money at set intervals, no matter what the market price is at the time. The aim is to spread purchases over time so the average price you pay can smooth out the ups and downs of the market. It does not promise profits or prevent losses. It simply gives you a steady plan.
With DCA, you buy more units when prices are lower and fewer units when prices are higher, since the cash amount stays the same on each purchase. Over many purchases, the average cost per unit may end up lower than if you tried to guess the perfect single entry point.
Pick an asset, choose a schedule like weekly or monthly, and commit a fixed dollar amount each time. You follow the plan regardless of short-term price moves, which helps you avoid acting on fear or hype. The method focuses on building a position gradually at an average cost.
For example, imagine committing 100 dollars on the first day of every month into a single asset. In months when the price is lower, your 100 dollars buys more units. In months when the price is higher, it buys fewer units. After many months, you can total the units you own and divide by the total money spent to see your average cost per unit. That average reflects the mix of high and low purchase prices you encountered along the way.
Many investors use DCA to reduce stress around timing the market. It replaces one big purchase with a routine of smaller ones, which can make market swings feel easier to handle and keep emotions out of the way.
DCA is not a guarantee. If the asset keeps falling for a long period, the value of your position can still decline. It may also lag behind a lump-sum purchase during strong, steady uptrends because part of your cash sits on the sidelines waiting for future buys.
The approach is popular in crypto because prices can move a lot in short windows. Setting a recurring amount can help you participate without trying to predict each swing, and it can make it simpler to stick to a plan over months or years.
