COME JOIN A MATHEMATICAL RESEARCH EXPERIMENT.

Test the DoublePennies™ Experiment for $10.

You can get rewarded up to $500.

Inspired by "Double a Penny for 30 Days" — a mathematical concept and theory about exponential growth — DoublePennies invites you to join a real-world experiment designed to grow your funds and support your spending goals.

How It Works:

  1. Pay a no-risk $10 research fee to participate.

  2. Track your progress and receive payments as you reach each milestone.

  3. Earn up to $500 in total cash rewards plus additional incentives for successful completion.

What Is a Milestone‑Cycle?

A Milestone‑Cycle is one full round of participation in the DOUBLEPENNIES™ EXPERIMENT.

  • Each $10 participation belongs to one specific, independently evaluated Cycle.

  • Milestones let you monitor the movement and growth of your DoublePennies™ throughout the Cycle.

  • Completion of the Cycle may reward you with up to $500 USD.

  • After completing Phase 1, your experiment transitions naturally into Phase 2: Spending for a Lifetime.

The Milestone‑Cycle is not only a tracking tool—it is your first hands‑on experience with stewardship, responsibility, and shared growth.
