As we all know that there are private owners who supply power to the locals coming from different resources like geothermal, windmill, waterfalls and etc.
I'm sure some have power because the country should have massive fuel reserves but apparently the problem Venezuela has is organising and putting resources to efficient use. So those with best access to power I guess is government and politics related and not useful industry that could help them recover or even essential services like hospitals and similar.
Theres no chance of mining but running a pi over solar panel shouldnt be the extreme or impossible scenario but I guess few have this in operation and so theres likely very poor network in operation to transact. I read of people using jetski to go far enough in the ocean to get a mobile signal from a neighbouring country to clear credit card transactions, I imagine bitcoin could still be of use but no doubt they have massive challenges sadly.
The country has the worlds largest proven oil reserves I will remind everyone, this is such a sad failure of what could be a very able nation. Somehow the oil has turned into a curse, now they got Russians set to occupy the place and we have a possibility of security worries in the region similar to the Cuba scenario that occurred. Russia is known for regularly challenging the borders of neighbouring countries as part of their activity. Russian activity in Syria coincided with the shooting down of an Israeli jet for example. In Ukraine they lent over powered rockets to a militia and shot down a passenger jet departed from Netherlands with the loss of hundreds of lives, its not likely they turn this situation positive for anyone
