While a lot of governments have talked about issuing crypto currencies, Venezuela is the first off the blocks. Even though the government may claim it is backed by oil, I don't see it taking off. When people don't trust your fiat paper currency, why should they trust fiat cryptocurrency?
Everything issued by the same rotten and corrupt government will always end up going down the same way. It's clear that people there need something that's not tied go the government at all.
While I would love to see them use Bitcoin on a massive scale, we can't ignore its current limitations, and for that reason I hope that in the meanwhile they adopt local currencies as have been set up already.
I am not sure how safe these local currencies are since they might be subject to counterfeit rather easily, but it seems pretty functional in parts where people have agreed to adopt it, which is somewhat nice.
No one should ever rely on something the Venezuelan government comes up with.
