Dollar-Cost Averaging Mechanics

What DCA Is

Dollar-cost averaging means buying a fixed dollar amount of an asset at regular intervals — typically weekly or monthly — regardless of price. You buy more units when price is low, fewer when price is high. The average price you pay over many purchases approximates the average price during the period. DCA is the most popular retail crypto investing strategy because it eliminates the question 'when should I buy?' and reduces emotional decision-making.

The Two Frames

DCA can be framed two ways. **Risk reduction**: instead of risking all your money at one entry price, spread across many — reducing the impact of bad timing. **Lower expected return**: by leaving money out of the market while you wait to invest the next chunk, you miss out on average drift. Both framings are accurate. The strategy works for risk-averse investors at the cost of expected return; for time-diversification of capital, not for outperformance.

How DCA Has Performed in Crypto

Historically, BTC DCA over multi-year windows has produced strong returns despite extreme volatility — because the long-term price trend has been up. A user who DCA'd $100/week into BTC from 2017 onwards has substantial gains today, despite living through three major 70%+ drawdowns. The strategy's value isn't in beating buy-and-hold (it rarely does in an upward-trending asset) — it's in providing a discipline that lets investors actually hold through drawdowns.

• Buy fixed amount at fixed intervals regardless of price
• Eliminates timing decisions and reduces emotional trading
• Mathematically: lower expected return than lump-sum in trending-up markets
• Practically: provides discipline that lets investors hold through volatility
