How it works
Core logic
Invest a fixed dollar amount on a recurring schedule. When price is low, you buy more units; when price is high, you buy fewer. Over time, your average cost smooths out.
When it profits
Works best in assets with long-term upward trends. Historically strong for BTC and ETH over multi-year horizons.
When it loses
Loses if the asset enters a prolonged decline with no recovery. Also underperforms lump-sum if you happen to buy at a major bottom.

Lump sum outperformed in this scenario (steady uptrend favors early entry).
Simplified model assuming linear price change. Real DCA returns depend on actual price path and volatility.

Risks
What can go wrong
medium risk
Long-term downtrend
If the asset price keeps falling for years, DCA just averages into losses.
low risk
Opportunity cost
Money sitting in cash waiting for next buy could miss short-term rallies.
low risk
Fee accumulation
Frequent small buys mean more transactions and more total fees paid.

FAQ
Common questions
How much money do I need to start DCA?
Most exchanges let you start with as little as $10 per buy. But to make fees worthwhile, $50–100 per period is a more practical minimum.
Daily vs weekly vs monthly — which frequency is best?
Historical backtests show minimal difference in long-term returns. Weekly is the most common choice — frequent enough to smooth volatility, infrequent enough to keep fees low.
Should I DCA into BTC only, or diversify?
BTC-only DCA is the simplest and historically most reliable approach. If diversifying, stick to 2–3 large-cap assets to keep it manageable.
