Dollar-cost averaging (DCA) means investing the same amount at regular intervals, whatever the price. For example, you buy ISK 10,000 worth of crypto on the first of every month instead of ISK 120,000 all at once. The aim is to spread your purchases over time so you don't have to guess the right moment.
How does it work?
When the price is low, your fixed amount buys more units. When it is high, it buys fewer. The average price you pay evens out.
Example: you buy ISK 10,000 worth three months in a row. In the first month one unit costs ISK 1,000, in the second ISK 500 and in the third ISK 800. You get 10 + 20 + 12.5 = 42.5 units for ISK 30,000. Your average cost is about ISK 706 per unit, lower than the average of the three prices, which is about ISK 767.
DCA often goes hand in hand with HODLHODLCrypto slang for holding on to your crypto for the long term instead of selling when the price swings., buying to hold for the long term.
Benefits and limits

You buy according to a plan, not out of FOMOFOMOThe fear of missing out, which pushes people to buy in a hurry when prices rise fast, often close to the top. or fear. The same idea is behind regular saving, such as a supplementary pension.
DCA doesn't guarantee a profit, though. If the price falls over the long run, you still lose money. If the price rises steadily, buying everything at the start would have worked out better. Also check whether each purchase carries a fixed fee, because that makes small amounts relatively expensive.
