Petro's future price doesn't depend on whether Venezuela's government is good or evil, popular or unpopular, etc.
Petro will be used intensively in purchase of Venezuelan oil, in commodity imports by Venezuela, etc., so demand of Petro will rise as will its price... unless, of course, Venezuela's government issues a larger amount of Petro or it succumbs due to US aggression.
Thank you for the intresting topic, I been waiting for that subject, do you personally think the price will follow the oil price or it was just an indication?
Supposing that Petro is a merchandise with a fixed (invariable) offer (say 100,000,000 Petros), its price will fluctuate directly (rise or fall) as the demand of Petro rises or falls.
I understand that Venezuela's government has said that if Petro's price, at any moment, falls below the price of a barrel of oil, the Venezuelan government will buy your Petros at the oil price of that moment.
