...In an ideal world, it’s simple: buy low, sell high. In reality, this is easier said than done, even for experts. Instead of trying to “time the market,” many investors use a strategy called dollar-cost averaging (or “DCA”)  to reduce the impact of market volatility by investing a smaller amount into an asset — like crypto, stocks, or gold — on a regular schedule

DCA might be the right choice when someone believes their investments will appreciate in the long term and experience price volatility on the way there.
