I helped many of my co-workers in latam get started in bitcoin while they were in Venezuela and Argentina. It's how they were able to survive and eventually get out without being completely broke. However this is nothing new. Bitcoin just happens to be a new method to use. In the past they would take earnings and immediately convert it to physical assets for barter. Or coupons in underground markets that could be traded for goods at vendor tables.

Ahhhh Blockstream and then a hero comes along with the strength to carry on I'd serenade you all night my friend.
