Or a service like Wise which is cheap and takes a few minutes most of the time.

Never had much of a need for other services when transferring across the globe.

They're not available everywhere, and the neo-banks in general are tightening their processes to a point where they're becoming difficult to use. I've had multiple situations now where Revolut denied things like a tap payment at a restaurant in NYC because it was an "unknown recipient". Of course they don't notify you of it, leading to an awkward 5 mins with the waiter while I rummage through the app to figure out why I can't use my own money this time. Fast and convenient it ain't

I suspect parent is using "a service like Wise" even though they believe they're using Crypto. That's because for an end to end transaction to complete in under 10 minutes it has to be performed by an exchange (not actually settled on chain). There are many cases like this where the "crypto" part is just theater. Money is being moved the tradition way by altering records in a non-distributed database.

Depends on the chain. Some networks are quite fast.

But it could also be theater, yeah. A friend of mine buys USDT on a P2P exchange and immediately sells it (so, sends money to a stranger’s bank account and then gets paid by another stranger). It could just as well be some e-wallet thing like WebMoney or whatever, but the fact that you can move USDT to your own wallet instead of immediately selling it makes it a bit more reassuring I guess.
