The Bitcoin Time Machine

Answer the question everyone asks: "What if I had bought Bitcoin instead?" Pick something you bought โ€” or model your own dollar-cost-average plan โ€” and see the real math.

What would that purchase be worth in Bitcoin today?

Pick something you bought (or spent money on), tell us roughly when, and we'll show you what that same dollar amount would be worth today if it had gone into Bitcoin instead.

Why We Built This

Every Bitcoin calculator online does the same thing: enter an amount, see a backtest. We wanted something that actually makes the number mean something โ€” tied to a purchase you remember, run entirely in your browser, free forever, with nothing to sign up for and nothing tracked.
