Also noticed in this article, coinsecure will allow trading of PTR across India apparently - https://www.newsbtc.com/2018/04/30/venezuela-coaxes-india-pay-crude-oil-petro-cryptocurrency/

Thats big news because India has very little oil to spread between its 1 billion people.  They are very active population also with alot of growth because the majority of the country is actually below 30 years old.
An incredible contrast to large parts of the Western world.   India I think could grow so much.

India relys alot on LPG or propane gas type fuel, I know they have been large buyers of oil from Iran even during difficult times for that country.   It would be a big deal to secure a buyer for PTR in that route I guess.   In theory India could also use gold but I think they retain this as a security only, dollars obviously causes problems for Venezuela and Im not sure why the Ruppe isnt used maybe bilateral trade is not as high as it could be.
