Dollar-Cost Averaging (DCA)
Definition
An investment strategy of buying a fixed dollar amount of an asset at regular intervals regardless of price, reducing the impact of volatility on your average purchase price.
Dollar-cost averaging is one of the simplest and most effective investment strategies. Instead of trying to time the market with a single large purchase, you invest a fixed amount at regular intervals — weekly, biweekly, or monthly. When prices are high, your fixed amount buys fewer units; when prices are low, it buys more.
Over time, DCA tends to produce a lower average cost per unit than the asset's average price during the same period, because you naturally accumulate more units at lower prices. This mathematical advantage, combined with the removal of emotional timing decisions, makes DCA popular among both new and experienced investors.
DCA is particularly effective in volatile markets like crypto. Bitcoin's price can swing 20-30% in a month, making lump-sum timing extremely difficult. An investor who DCA'd into Bitcoin weekly over any multi-year period in its history has historically performed well regardless of their start date.
The main drawback of DCA is that in a consistently rising market, lump-sum investing statistically outperforms DCA about two-thirds of the time. This is because DCA delays full market exposure. However, the psychological benefit of avoiding a poorly timed lump sum often outweighs this statistical edge.
Most brokerages and exchanges support automated recurring purchases, making DCA a set-and-forget strategy. The key is consistency — sticking with the plan during both euphoric highs and fearful lows.

Frequently Asked Questions
How often should I DCA into crypto?
Weekly or biweekly purchases tend to provide good averaging in crypto's volatile markets. Monthly works too but captures less price variation. The most important factor is consistency — pick a frequency you can sustain long-term.
Is DCA better than lump-sum investing?
Statistically, lump-sum investing outperforms DCA about 66% of the time in rising markets. However, DCA reduces the risk of investing a large sum right before a downturn and is psychologically easier. For volatile assets like crypto, DCA is often preferred.
