A pile of USD can get you robbed and tossed in jail in Venezuela these days.
That's what makes it important to enable Venezuelans to hustle with each other unofficially, sub rosa.
DOn't get me wrong: I loathe bitcoin and its boosters, and I pity anyone who actually needs it to get by. But Venezuelans are in that number.
If people know you have Bitcoin, they can just beat the wallet password out of you and throw you in jail just the same.
