Reformation is already knocking at your door. Since El Salvador made Bitcoin a legal payment, it will be a matter of several years before mass adoption will start. Btw, Republic of Cure currently also authorise and regulate cryptocurrencies like Bitcoin, but this is not discussed widely. So there is actually no need to wait for 15 years.
Returning to El Salvador, using Chivo wallet app you can pay and receive payments in Bitcoin already now. As well as get crypto plastic cards with auto exchange option on and use them for payment. You will only see how your crypto balance decreases with every payment (but detailed statistics is also available in dashboard).
