Saudi Arabia · SAR
The same story, told 2 ways: in SAR, prices only rise. Measured in Bitcoin satoshis, the picture inverts. Each chart says what it is — observed data or a labeled model.
01 · One SAR, measured in sats
Observed · FX snapshots × BTC closes
2026: 1 SAR bought 434 sats. Today: 420. Log scale — the fall is the story.
02 · The burger agrees
Observed · The Economist Big Mac index
Independently observed prices for the same product, twice a year — the observed cross-check on everything above.
Go deeper: everything Saudi Arabia buys, in sats · where the SAR ranks in the Fiat League · your own salary in sats
