Bitcoin is now legal tender in El Salvador

El Salvador is innovation - and an attempt to ensure that their remittance economy works more efficiently without Israeli-influenced bankers creaming >8% via Western Union etc
Ukraine is a sign of desperation, a need to get noticed and admitting that capitalism there has failed miserably. They produce little of any value that is not foreign controlled and their only real source of foreign income is about to get bypassed by a more efficient method - Nordstream2.
This means little in reality for Bitcoin - El Salvador was a breakthrough, Ukraine is a pathetic attempt to jump on the bandwagon with an economy that will take a LOT more than Bitcoin to turn it around.
