I've never heard of CriptoDebit so I don't know the whole back-story, but this looks like an obvious scam.  There's no such thing as an anonymous debit card to begin with, any debit card transaction can be traced, and most purchases can easily be linked to a specific individual.  Online purchases of physical goods require a shipping address, and meat-space purchases can be subject to surveillance cameras.  Any service claiming anonymity with a debit card is flat-out lying.
