Say the currency once, and stop hedging about old prices.

The balance read "US$74.67 USD" — the symbol and the unit tag saying the same thing twice. Amounts now format bare, like sats and BTC do: whatever labels the number says which money it is. The currency symbol stays where a number stands alone in prose, which is the "Worth then" line and nowhere else. The '~' marking a payment older than any price we sampled is gone too. It was bookkeeping the beta doesn't need: a payment we have a price for is shown at that price, one we don't is shown at today's, and nobody has to learn a squiggle. The currency picker has moved to sit beside the language picker at the foot of the page — display preferences together, where they're findable. It spent one day under Settings → Network, where it wasn't. And a bug this feature exposed rather than caused: nine notices end in the word "sats" in every language we ship, and were being handed the display unit. "Uncooperative exit costs about US$2.03 sats" — and long before fiat, "about 0.00435397 sats" for anyone in BTC. They're given sats now, which is what they claim to be showing.

Every payment remembers what it was worth.

A payment is worth what it was worth WHEN IT HAPPENED, and that number is gone by the time you look at it unless someone wrote it down. So every price the app fetches is kept as a sample — one an hour, a few months back — and a payment's fiat value is read off the sample nearest its own timestamp. The history rows and both detail pages (on-chain and Spending) pass the time the money moved; balances and forms use the live price, as they should. A payment older than any sample we hold is priced at today's number and says so with a '~', because that is a different claim and shouldn't look like the same one. The detail page spells it out: "Worth then $X · $Y now". Fiat is a third position on the unit toggle rather than a second number beside the first: sats → BTC → your money → sats. One figure, and which figure is your choice. The ring skips fiat entirely until a price has been fetched — a third position showing blanks is worse than two that work. Typing an amount with the unit on USD means dollars, priced now. The rates are coinos' own endpoint, a map of every currency it knows, so there's no third party watching what the wallet asks about; the currency picker under Settings → Network lists all of them. Changing it starts the recorded history again rather than relabelling samples taken in another currency.
