“Opportunity Cost” will change spending for Bitcoiners (Patreon)

A new browser tool called “Opportunity Cost” changes how you see online shopping prices. It shows every price in Bitcoin (BTC) and its tiny unit, satoshis, next to regular money prices. This helps you see what things really cost in Bitcoin, which might make you rethink buying stuff. The tool wants to help you spend smarter by thinking about Bitcoin’s limited supply. It’s private, doesn’t collect your data, and hopes to get both Bitcoin fans and doubters to shop more carefully.
