I scanned a qr code, entered an amount and clicked pay in my banking app. It automatically converted the amount from my local currency to UAH. Negligible or no fee (can't recall and can't check right now).

Seems that crypto is just a technical solution to socio-political issues that plague parts of the world.

Sure. But one thing cryptocurrency is terrible at is requiring that you do your own op-sec. Maybe you're good at that sort of thing, but because of the inherent lack of controls to reverse transactions made by mistake or accidental fat-fingering other details, such as the address, it's pretty bad for the less tech-savvy.

Did you ever bother to check that "single link from a donation page" to make sure it's really the correct one?

I love being able to call a bank if my VISA card gets stolen and charged up to high heaven and get that all reversed.

Meanwhile, good luck with that NFT that mysteriously landed in your wallet that has bad coding in it to wreck your day. But yes, mass adoption imminent!

I also did this for Ukraine with BTC.

My physical banks are in 3 different countries, I have not been in an office in years, and I still can send money to UA based organizations easily.

Why would being physically in a bank be needed?

And as a crypto enthusiast you've chosen a bank stuck in the 1980s which doesn't have an app or website? Is that to validate your crypto enthusiasm?

Interbank transfers work the same way regardless of country ( with the exception of sanctions - you can't wire money to Russia or Iran just like that), over the SWIFT protocol with an IBAN and BIC. Usually you pay a fee for the transfer and currency exchange - some banks abuse that, some are competitive.

So you chose to unbank yourself :)

I have transacted millions in crypto and wire transfers. Banking with crypto is like the 1970s - exorbitant fees. To do anything useful with it I have to offramp to fiat which drum rolls ends with a wire transfer.
