What the Bitcoin comparison tool simulates
The lump-sum vs DCA tool deploys the same total capital either all at once or on a schedule across historical BTC prices. You see ending value and path differences — not a guarantee of future outperformance.
Open it when you are deciding between “buy now” and “spread buys over weeks,” and you want a concrete past window rather than a slogan.
How to choose a window without overfitting
Try bull, bear, and sideways ranges separately. One lucky 2017-style window does not settle the debate. Pair results with the historical price checker and the DCA calculator for custom schedules.
Fear & Greed can remind you when emotion is loud; it should not replace position sizing or fee math.
Practical next steps after the chart
If DCA wins on path risk for your personality, open the DCA calculator and entry ladder to structure buys. If lump-sum wins in your sample and you accept drawdown risk, size with profit and fee tools so commissions do not erase the edge.
