And you don't use BTC as the fees are way too expensive.
This is what people are doing in Venezuela for example.
Cryptocurrency is a fascinating technology and social experiment but so far has no unique use case other than speculation.
The real use-case is transferring to and from places that you cannot normally do. Smartphones are prevalent in Venezuela for example, but it's basically impossible to send money in or out unless you use cryptocurrencies.
The charity eatBCH uses this to give food to Venezuelans for example: https://eatbch.org/. I think that's a pretty unique use case.
One of the point of cryptocurrencies is that some countries may think certain things are illegal, but that doesn't make them wrong. To me helping to feed starving Venezuelans by sending them help directly is morally right, even if it was illegal.
Yet it's nothing compared to hyperinflation. In May 2019 prices in Venezuela doubled in only two days... every day.
While Bitcoin is volatile it's relatively stable compared to what Venezuela and Lebanon are going through today.
With Bitcoin, anyone can start a cash-to-bitcoin/bitcoin-to-cash office. All you need is a phone with Internet.
Could Western Union solve the same problem? In theory, yes, in practice, the overhead cost of joining the network means the guy with a phone in some remote village isn't going to do it.
This is obviously mostly relevant where the classic solutions aren't already ubiquitous. Want to wire money from Germany to France? Just use SEPA. Want to wire money from Germany to the US? You're probably better off with some traditional money transfer service like TransferWise or (for bigger amounts) a Forex/brokerage account.
Want to "wire" money from a remote village in Africa to a remote village in Asia? That's where you might benefit from your neighbor having set up a physical crypto exchange.
