I've never done it, but when I lived abroad and I had to transfer money, I got fleeced by banks and then (a few years ago) there weren't really any alternatives. I don't have any skin in the game with Bitcoin, but I guess that left a foul taste in my mouth.

There've been other comments about Bitcoin that are a bit more nuanced and interesting, in one case there was a gentleman from Argentina making an impassioned case for the use over and against the polices of his government.

I think there's an element of institutional mistrust that Bitcoin claims - maybe wrongly, given how centralized it is - to solve.
