If this news is true, then definitely this is a win win. Win for venezuela because they seem to want usability for their petro. The only way for it to pump is to give in exchange a discounted price for oil. For india, to purchase this currency in the exchange of 30% is certainly beneficial in order to save their money from the purchase. If venezuela will offer this to the world, i think the worl will then find the need to buy petro.
this is mainly done to go around the sanctions and stop using US dollar. it is not the "world" they are offering their coin to but only another country that is not so pro US in the world.
in any case they are increasing the popularity of their created coin which is a good thing for them. i am interested to know how can one buy this coin though. is it listed anywhere like on regular exchanges or is it only in their country?
