I’m building an e-commerce site and want to know which payment gateways are best for small businesses. What should I consider in terms of security, fees, and integration when making my choice?

I live in a small town where there aren’t many local exchangers. How do you usually exchange crypto for local currency if there aren’t physical exchange offices nearby? Any practical solutions?

I sell digital products worldwide and need a payment system that’s secure, fast, and convenient for customers in Europe and abroad. What should I consider when choosing one?
