Well, as long as euro prices are highly stable and Bitcoin stagnates. If they start euro stimmies again, all bets are off.

We like pricing in sats because we're offering a service to people who want to get a Bitcoin economy going. As much fun as it is to zap each other, it's more exciting to move larger sums. Feels more significant and it's a harder test.

The fee-advantage of lightning tends to thin out, once you get over 100 euros, or so. I had to use Phoenix to accept payment, at one point, cuz channelz ain't channeling, and the fees were higher than on-chain. 😬 On the other hand, on-chain can be sorta slow. Didn't show up, confirmed, until hours later.

Another thing that comes up, in a real-life situation, is that one person can collect cash euros (rounded up, to cover fees) from multiple people and then send the sum of the payments on-chain or over Lightning. I thought that was a clever work-around, for bad internet connections or whatever. Combine the two cash monies.
