June 10, 2025, the team behind TFTC (Truth for the general public) I’ve started a new project called opportunity costAn extension for browsers that introduces tools that try to translate how users perceive prices on the Internet.
Initially available in Chrome and Brave, this extension, featuring a version of Firefox under development, automatically converts Fiat Currency prices to Bitcoin (BTC) equivalents as users navigate through various websites.
Main features of Opportunity cosIt lies in its ability to detect Fiat prices, including the US dollar, euro, and yen, on a variety of platforms, from Amazon to Airbnb or Zillow. Show it in real time from the perspective of BTC. This is achieved without manual calculations and provides conversions that alternate in large quantities (SAT) and small quantities depending on the user’s preferences.
The team behind the project highlights this feature seeking to promote immediate understanding of the value of alternative metrics; It’s separate from traditional currency fluctuations.
Development of opportunity cost It addresses a particular vision: as reported by Cryptootics, by using Bitcoin as a standard, by using Bitcoin as a standard, and by using Bitcoin as a standard, by using it as a standard.
Creators are in the context of financial uncertainty; This tool allows users to develop “Bitcoin intuition”they are used to buying currency units and valuing products they think better. The extension is not limited to e-commerce sites. Its design makes it suitable for use on any website.
It is easily revealed that this tool is merely a nominal. It works to evaluate the price of Bitcoin (BTC) products and does not include the possibility of purchasing online products using currency If the shopping processor is not previously permitted.
Technically, opportunity costTFTC tools aim to prioritize privacy and performance. According to the developers, all conversions are processed locally in the user’s browser without collecting or sending personal data. Additionally, the code is open so the community can see and contribute to its development.
Customization options include conversion visualization and adjustments to support multiple coins. Includes USD, EUR, GBP, JPY, CNY, INR, CAD, AUD, CHF, SGD; There are plans to expand this list in the future.
The project also includes an educational component, which will invite users to install an extension and “think about Bitcoin,” leaving behind the “Fiat Illusion” that was called. The story suggests an approach to adopting Bitcoin as an alternative to the current currency system, but the specific calendar in the Firefox version is not detailed There is also no immediate plan for mobile applications. Though some users have already expressed interest in this possibility.
Before adopting such tools, it is wise to consider the risks associated with using browser extensions. Recent research shows that more than half of these applications can present vulnerabilities that could undermine user privacy and safety, such as excessive access or potentially malicious data access.
