Economies such as Greece, Venezuela etc who face Fiat based Debt Crisis should take refuge in crypto currencies. These Governments should legalize cryptos as a legal digital currency & allow trade through it. Incase Govts (sometimes these are proxy govts) aren't able to do it, people as a democratic right should start using cryptos as a legit currency.
Fiats have a competition & no better way to infiltrate the FIAT monetary system than to attack its controlled vulnerable economies!
