Meaning
Two currency signs linked by arrows, showing one currency being swapped for another. It stands for currency exchange: money changers, exchange rates and converting cash before a trip.
Travellers use it when hunting for good rates, and it also suits posts about prices abroad, cross-border shopping or paying friends back in another currency: “Changing money at the airport 💱 the rate is terrible” For simply talking about money, 💵 or 💰 are more common.
