It’s possible, just very inconvenient. You end up getting massive amounts of change that you have to lug around to spend.

Depends on the country. I’m teaching in Thailand and here you can’t do any banking through a browser. You can only use the bank’s official app and you don’t even have a login/password for it, you have to go to the bank and activate the app in person as a foreigner (I think Thai citizens can do it online but foreigners have to do it in person). Nobody takes actual cards for the payment and you pay everywhere by scanning QR codes which has to be done through the app. If you buy a new phone you have to activate the app again at the bank’s office. It’s really annoying and the reason I probably can’t go with GrapheneOS or any other custom roms because the bank app is absolutely essential.

It will never be ready. It doesn’t even make sense. To transact with real fiat like the US dollar, you’ll have to go through an official on-ramp and an off-ramp of the respective government. And to do an international transaction you’ll have to use one of the widely accepted systems like SWIFT. GNU Taler doesn’t appear to address anything like that. Anyhow, my comment was made with the premise of this whole thread in mind, i.e. “Bitcoin is stupid” or “snake oil”. Yet there’s no alternatives to what crypto provides. So is it that stupid after all?

Please describe how I can send the money to my mom in Russia (disconnected from SWIFT) with GNU Taler today. I’ll wait.
