What if you'd dollar-cost-averaged into Zcash instead of something else? Pick a start date, purchase frequency, and amount, then toggle any lines on or off. It simulates buying that much every period at real daily closing prices, not a smoothed or backtested estimate. QQQ/SPY use Yahoo Finance's dividend-reinvested (total-return) series, not plain price.
Every return here is money-weighted (XIRR), not a naive final÷initial ratio. It discounts each purchase by how long that money has actually been invested, because a DCA position is never a single lump sum. Three of the windows are fixed and end today: since Zcash's launch (2016-10-29), the trailing 5 years, and the trailing 1 year. Selected is the start date, frequency and amount you set above, so it moves with the calculator.
