The transform tool, EUR, GBP, JPY, CNY, INR, CAD, AUD, CHF, SGD in BTC.
Opportunity Cost is a nominal tool, and does not allow paying in BTC.
On June 10, 2025, the team behind TFTC (Truth for The Commoners) launched a new project called Opportunity Costan extension for browsers that introduces a tool that seeks to transform the way users perceive prices on the Internet.
Initially available for Chrome and Brave, with a version for Firefox in development, this extension automatically converts prices in FIAT currency to its equivalent in Bitcoin (BTC) while users sail through different websites.
The main functionality of Opportunity Cost It lies in its ability to detect prices in Fiat – as US dollars, euros or yen – on diverse platforms, from Amazon to Airbnb or Zillow, and show them in real time in terms of BTC. This is achieved without manual calculations, offering a conversion that alternates between BTC for large amounts (sats) for minor amounts, depending on user preferences.
He Team behind the project It emphasizes that this characteristic seeks to facilitate an immediate understanding of value in an alternative metric, away from the fluctuations of traditional currencies.
The development of Opportunity Cost It responds to a specific vision: to promote a change in the perception of economic value through the use of Bitcoin as a standard, which has already been attempted by some proposals for improvement in the past, as cryptootics reported.
Creators argue that, in a context of monetary uncertainty, This tool allows users to develop a “bitcoin intuition”getting used to evaluating purchases and goods in a monetary unit that they consider better. The extension is not limited to electronic commerce sites; Its design allows its use on any website.
It is briefly clarified that this tool is merely nominal; It works to assess the price of goods in Bitcoin (BTC), and does not include the possibility of buying online goods using the currency If shopping processors do not allow it in advance.
In technical terms, Opportunity Costthe TFTC tool seeks to prioritize privacy and performance. All conversion is processed locally in the user’s browser, without collecting or transmitting personal data, according to the developer. In addition, the code is open, which allows the community to review and contribute to its development.
Among the customization options are adjustments in the visualization of conversions and support for multiple coins, including USD, EUR, GBP, JPY, CNY, INR, CAD, AUD, CHF and SGD, With plans to expand this list in the future.
The project also includes an educational component, inviting users to install the extension to “think about Bitcoin” and leave behind the so -called “Fiat Illusion”. This narrative suggests an approach to the adoption of Bitcoin as an alternative to current monetary systems, although a specific calendar is not detailed for the Firefox version nor are immediate plans for a mobile application, Although some users have already expressed interest in this possibility.
Before adopting tools like this, it is prudent to consider the risks associated with the use of browser extensions. Recent studies point out That more than half of these applications can present vulnerabilities, such as excessive access to potentially malicious data or updates, which can compromise user privacy or safety.
