Is not that they don't have money to eat, they don't have enough food to eat. As I see it, at the hear of the issue is broken economics. Sound money, like bitcoin, could be a great solution to several problems of economics of Venezuela.
Bitcoin's volatility is the opposite of what Venezuela needs. About the only proven solution for hyperinflating countries with poor institutions is a currency board [1]. You peg the local currency 1:1 to an external currency. If that doesn't work, you switch to a hard currency.
Many other currencies are also stable - the NZD for example, but I suspect (with no proof either way) a large change in their use may cause issues.
Typically USD is chosen, as that is the international currency of oil. EUR is I think second, mainly for political reasons.
