How does crypto help with multi-currency bookings?

It reduces the number of currency conversions in checkout. Instead of charging a customer in their local currency and dealing with FX rates, card FX markups, and settlement delays, a travel business can accept one payment currency (for example, a stablecoin) across markets. The customer pays from a wallet, and the merchant settles in a preferred currency which makes reconciliation simpler and cash flow more predictable across regions.
