It's fun to offer people Solver as payment. Helps break the ice to talk about Sound Money and the problems of FIAT, and how Bitcoin is Sound Money which can fix it all. In the last month I paid for 3 breakfasts and 10% of a used car with Silver coins and rounds, totalling over $300. The economy needs sound money in any form, carry silver with you along with cash. If people don't accept Bitcoin yet, offer silver and see what happens. 🙂
