Only places that use cash are grocery stores and some essential businesses for locals. As a tourist it's basically impossible to spend cash anywhere. Their current government tries to bring back cash tho and want to make sure that cash works as a viable alternative in case of war were the power grid and banks may get targeted early on.

As for CBDC it's all happening in the back-end, you wouldn't know you were using CBDC other than after paying your bills and transaction apparently registers immediately instead of after 3 bank days with a 5% risk of disappearing beyond trace, which was the case with the old system.

E-krona or E-coin does look interesting tho as it's intended use is for the government to take control over money instead of privately owned corrupt piece of shit bankfags controlling everything while practicing usury on the people. Instead of taxes going to pay of debt, the government would have no debt and inflation would in turn work like a type of tax. And although history is full of examples were governments have mismanaged this sort of trust, the system itself is good if used with caution.
