It's a 20k inhabitants city in southern Brazil. A guy started orangepilling local business and now there are more than 200 accepting sats. It's more than lugano but without the 10m francs from the city hall. And it really has a circular btc economy now, check on btcmap. I think it's the biggest city with a btc circular economy and without a bukele or lugano mayor, it came from the local people in a total voluntary way.
