How to read this
What a steady, automatic Bitcoin purchase plan would have done — using real daily closing prices from our own database, computed in your browser.
- The orange area is what your stack is worth; the dashed line is the cash you put in. The gap between them is your gain or loss.
- Yearly returns measure each calendar year on its own — a red year early on can still sit inside a green total.
- “Per year” is the money-weighted average (IRR): the single yearly rate that, applied to each contribution for exactly the time it was invested, lands on today’s value. It’s the honest annual number for gradual investing.
- DCA shines when the start was badly timed: from a market top it beats the lump sum; in a straight bull market the lump sum wins.
- Past prices are not future prices. This is history, not advice.
