We just launched Opportunity Cost!

It's a browser extension that converts prices into $BTC as you browse, while protecting your privacy.

No more fiat illusions. Think in #Bitcoin.

🧵Here's how it works.
https://www.opportunitycost.app/


What it does: Opportunity Cost automatically detects fiat prices on any website and converts them into BTC in real-time.

From Amazon to Airbnb, you’ll instantly see the true cost of your purchases.


Why we built it: We live in a fiat world, but the future is Bitcoin.

This tool helps you build "Bitcoin intuition" by training your mind to measure value in sound money, not debased currency.


Key Features:

1. Real-time fiat-to-BTC/sats conversion

2. Dynamic display: BTC for big numbers, sats for small

3. Works across all websites

4. Customizable display preferences

5. Lightweight & fast

6. Totally private


Opportunity Cost is 100% local processing. It doesn’t track you. It doesn’t send data. It’s fully open-source.

Supported currencies: USD, EUR, GBP, JPY, CNY, INR, CAD, AUD, CHF, SGD.

More coming soon.

Start thinking in #Bitcoin. The sooner you do, the sooner you escape the fiat illusion.

Install the extension. See the signal. Ditch the noise.
