It's clear that customers can pay with cryptocurrency if they want, but if the terminal is available for fiat payments, why do you think people will use digital coins? You plan to convert them into crypto users somehow?
Hello! Thank you for question!
There are at least two points:
a. Using cryptocurrency give a discount and money savings to customer.
b. If customer agree to get a discount then he will immediately and easy get his own Crypto wallet. All crypto <-> fiat conversions will be done automatically.
