Honestly I have never collected large amounts of crypto or from various people for payment purposes, only sigle buyers. I would still use Cake. But if you are running a business and invoicing and all that jazz you might want some commercial sofware to manage that.
Not a business or especially large amounts. I work in a casino environment and people are frequently looking to exchange crypto or online $ for cash / chips. So you're saying it would be pretty safe to exchange my cash for someone's crypto into a Cake wallet and then use the same wallet for pep purchases?
