I built a free Bitcoin Opportunity Cost Calculator — would love your feedback!

Hey

After a few weeks of building, I finally launched my side project

The concept is simple — the 'latte factor' is a well-known personal finance idea, but no tool showed it in Bitcoin terms. So I built one.

What it does:

• Enter any daily habit (coffee, Netflix, gym, eating out — anything)
• Set a time horizon and growth scenario (Bear / Base / Bull / Hyperbull)
• See exactly what that habit costs you in Bitcoin terms
• Includes a Freedom Planner showing your sovereignty milestone timeline

Example: $6 per day coffee habit → 10 years at Base CAGR → $138K in BTC you didn't stack

Tech stack: Astro + Vercel + CoinGecko API for live BTC price

No signup, no ads, completely free. Would love feedback on UX, features, anything!
