Opportunity Cost was created to help people better understand the value of their money in terms of Bitcoin. In an era of inflation and monetary uncertainty, Bitcoin provides a different perspective on value.
Our mission is to help everyone think in terms of Bitcoin's sound money principles, making the transition to a Bitcoin standard more intuitive for everyday purchases.
The extension is built with privacy and performance in mind, running entirely in your browser with no data collection.
