Maybe I'm misunderstanding what you wrote, but that's not how sanctions work. It's the people within their own country who are hurt by their country's sanctions, not sanctions from other countries. This leads to domestic companies buying less exports, which is supposed to lead to more domestic production (or hurt the other country's economy), but regular people aren't typically buying exports direct from the producers. That's not a problem Bitcoin can solve, unless import companies start using it or regular people start importing themselves.

However, it's still the wealthy who most benefit from crypto. It's the wealthy who make the barrier to entry higher, and it's the wealthy who can very easily manipulate the value of this value-less currency (just look what they can do with the stock market, and that's regulated).

It's not that I'm against the plight of the downtrodden, I just don't see how crypto actually helps them; like I said, it's another "American Dream," a promise of wealth that will never materialize for most, because the wealthy have rigged the system.
