From what I understand is I can use this in my paint business like a rewards program. When people come and buy paint I mix I can reward them with crypto. But how easy will it be for them and me ? Also big thumbs up because this will merge normal people into our crypto space with little knowledge they are even doing so. How many steps or hoops will I have to go through to set this up ? Do I need to set up a waves wallet ? and How do I get the customers to install it (or sign up ?)?
