Scenarios
The common questions, already answered. Open one to see the numbers, or change the inputs above.
What this leaves out. Prices are weekly closes from CoinGecko. No fees, no spreads, no taxes, and no slippage, so real-world returns run lower. Past performance is not a forecast, and a different start date can flip the story entirely. This is a backtest for understanding, not advice.
Equities are next. The BTC-vs-S&P comparison every DCA tool needs requires an equities data feed wired through the server layer. The engine here already accepts new assets. Stocks and gold drop in once that feed is connected.
