Bitcoin DCA Calculator
Plan how much capital you need to lend so each period earns enough interest to dollar-cost average into Bitcoin.
Stack BTC without spending an extra cent — let lending interest do the buying.
- ✓Your principal stays 100% in the lending pool earning more interest — it's never consumed.
- ✓Interest auto-converts to BTC every period — no manual transfers, no extra deposits.
- ✓Unlike traditional DCA that pulls $X from your salary each month, this funds itself entirely from yield — zero out-of-pocket cost.
