Maybe my experience with money changers colors my view.

The only time I've used one and not a bank is when making land crossings between countries in Central America. The money changers are just a random assortment of dudes walking around the bus depot ready to swap between 2-4 different currencies. And I've only done it for a small amount of cash to have on hand in case of immediate need.

I imagine a cottage industry would pop up as a result of situations like Lebanon given the government enforced cash shortage. I remember reading an article a while back, which I'm failed to dig up, which described a similar system appearing in Venezuela as inflation was getting out of control. Money changers would come to you to swap bitcoin for other currencies.

But I understand your point and this would be a sketchy alternative for the amount of money discussed.
