Hello,
(I’m co-founder of MonoPayments, white label payment platform for fintechs.)
If you want to pay less, you have to use local processors with local currencies. This would be a complex operation.
1. Establish a company at that jurisdiction
2. Make agreements with processors, it could be banks or wallet providers.
3. You need a treasurer (or CFO)
4. Foreign Exchange rates will be a concern after a while.
