They need stable currency, that is true. But is it foreign currency solution? This is also the way that one country colonize the other, in a way. Bitcoin can't help the country, it can only be support for individuals but it can't save economy and financial system in Venezuela. They need help but not in a way that will longterm only make them weaker and more vulnerable.
Using local currency will not help either, considering they would rather use a foreign currency. True, it could mean a way of colonizing. I guess they should fix internal affairs first, as the OP said the Electricity as well as maybe changing their
leader, they seem to not know how to run a country. I'm not a person that indulges into politics but at least I know if that politician fits for the role or not.
