Nature of payment gateway
Can I use a payment gateway to process crypto payments?
Yes.
"The cryptocurrency payment gateway ensures that the merchants and retailers can directly receive payments from their customers by integrating a crypto payment gateway into their list of available payment methods."
"The direct payment is in place only because a cryptocurrency payment gateway completely eliminates the intermediaries and third-party that add to the cost of a transaction. The transaction charges, in most cases, or just about the network charges and nothing more! This gives merchants more power over their revenues."
