Yes there is, sometimes they don't even remit but rather use btc. I send $10 a month to ~5 people in Venezuela and it's one of the only ways now to help out and/or live there
Can you provide more detail on how they actually use the bitcoin? Genuinely curious as in most countries the use cases are very limited, and there is a large cut when converting into/out of bitcoin that doesn't make it worth it.
There was solid episode of Odd Lots on cryptocurrency usage in Venezuela.
