I wonder what it would all add up to. This was just a demo (in the company cafeteria I think), but they still should be able to total up all the fees. No free lunch, right?
Someone on X did ask this:
I don't see any upside here, quite the opposite, actually. Anyone who buys USDb can just buy Satoshis, use them direct, and dodge all those fees except the standard LN fee. Marcus is talking about a 3% card fees, that even normal in the States? Over here in Portugal, we just pay a flat quarterly fee (mine's 5 euro) and that's it, no extra charges.
reply
usually the merchant pays the fees. Most consumers don't notice them, but it is normal for credit card processors to charge 3 - 5%. I've heard it's less in the EU.
reply
I heard that too, it's true. Totally slipped my mind
