How do you propose they trade Bolivars for BTC? Do you think VNZL mines enough to have a local market? See the restrictions on foreign currency purchases in VNZL (and what is effectively two exchange rates)
How do you propose the bitcoins are subsequently used? For buying basic items (like toilet paper, which gets smuggled from Brazil)
Airlines can't repatriate their earnings from VNZL. Oh I know, they should buy bitcoin! /s
But I assure you most of the well offs already have their earnings safely in a Miami bank account.
I'm not sure what's the story with credit cards there, but I assume the limits are strict.

That is one way to get the money out. As the article points out, others keep the money in bitcoin (which would have net them a handsome profit lately), but presumably you could also get an overseas bank account denominated in dollars.
Wouldn't it possible to buy real goods in venezuela using native currency ( like , say electronic equipment, or maybe something that doesn't loose as much value in secondhand market), and sell it online against bitcoins ?
I don't see how Bitcoin is a great solution here when it depends on utilities managed by the government for its liquidity...
Once internet is completely gone of course all you're left with is buying diamonds or gold, put as much as you can in your luggage and just run.
(The resale value is closer to fair, at that. Diamonds aren't actually rare.)
Which would mean that there would be someone selling as many of their bitcoins as possible for your money. If the situation is so dire that buying bitcoins is the obvious solution, who is going to sell them to you?
Buying them as a store of wealth would only be useful back when the Bolivar was worth something - as it stands, the black market exchange rate is several times the most generous official exchange rate (there are 3 official exchange rates for some reason). So buying BTC now would only make sense if the government currency had any further to fall.
