Pick a coin, an amount and a schedule. We replay real past prices and show what dollar-cost averaging would have produced, next to putting everything in on day one, including the rough patches.
A history lesson, not a forecast: past prices do not predict future ones, and many coins have fallen and never recovered. It uses Binance daily closing prices and your fee, but not slippage, taxes or missed buys. It is not investment advice, and it moves no money.
