Not sure if any of you are familiar with an online video game called Runescape but Venezuelans have flocked to that game in mass in order to farm video game gold and sell it for real money. They make much more farming gold, up to 10x the amount than they would make working a regular job in their economy.
This is the only way that I see Venezuela benefiting from cryptocurrency, at least it will help them add more money to their GDP if they use cryptocurrency to develop applications that people can makes use of, and use it to gather wealth from other countries. If I were them, I would also explore that area of gambling, because this session is really raking in so much money for countries where this gambling with cryptocurrency is situated.
Although even if they use cryptocurrency to generate money, they still have to put a lots of structures in place, I think their government too needs to work on their internal system that has been so corrupted which is one of the thing that led to their economy going down, so many areas needs to be tackled first before using crypto to generate money.
