Of course I've used Wise to send money. It was full of confusing KYC friction that took several days to resolve. Cost more than $0.05, took more than a few hours to complete, didn't allow me to use my own currency (crypto) and required my friend to also setup a Wise account and go through the same contortions on their end.

KYC exists to make life hard. It solves no real problems, just like the TSA at airports. Security theater at its finest. It is also easily circumvented too, making it questionable at best [0].

Lastly, saying something doesn't solve a real world problem, after I just explained to you that it does, is mind blowing absurd.
