DCA spreads entries over time so no single print defines your basis. It does not remove drawdowns — it reduces timing concentration risk.

Each buy: coins_i = Amount ÷ Price_i. Total coins = Σ coins_i. Avg price = Total invested ÷ Total coins.

$100 × 12 buys at $60,000 → 0.02 BTC, average $60,000, invested $1,200.

Same schedule while price drifts −20% → more coins and a lower average than the start price.

Is DCA better than lump sum?

Historically lump sum often wins if markets rise, but DCA can be psychologically easier and reduces regret from a single entry.

How often should I DCA?

Weekly or monthly is common. Match cadence to cash flow; fees matter more on tiny frequent buys.

Does this include exchange fees?

Not yet — slightly lower amount-per-buy if you want a fee haircut.
