How ₿Hold works

From a purchase to a perspective.

From a purchase idea to a longer view of what that money could mean.

Enter the purchase

Enter how much you're thinking about spending.

  1. Step 1: Enter the purchase. Enter how much you're thinking about spending.
  2. Step 2: See the Bitcoin equivalent. See how much BTC that money represents today.
  3. Step 3: Explore the model. See what that same BTC represents over time using the Bitcoin Power Law model.
  4. Step 4: Get perspective. Compare today's purchase with its modeled long-term opportunity cost.
  5. Step 5: Decide. Buy it—or ₿Hold it.

Perspective, not pressure

Saving isn't always dramatic.

Sometimes it's choosing home tonight.

₿Hold isn't telling you never to spend. It gives you another view before you do — so the choice feels clearer, not guiltier.
