Not sure about this whole thing. But I don’t really like the idea of satcards.

Can I ask why? And, have you tried It? I’m trying to find downsides to it. For now the biggest is that if you lose the card, you lose all the btc in it. There is no way to backup it. Which is probably a good thing.
To me it’s like printing an email, putting it in an envelope, buying a stamp, and handing it to someone. Just send them the email.
Nothing wrong in doing it, but it doesn’t make sense.
Nobody knows the private key and it always changes when you use it, I think this is one of the major differences compared to anything else. Tonight I will use it to buy some bitcoin with cash, at a pizza day meeting. I can still verify, but I don't need to bring any cable, app, wallet or whatever to receive the Bitcoin. It's so frictionless.
