Thanks for the idea. Could you give me more info so I can analyze it? Those websites you mention, for example. I am trying to focus on self-custody, so I want to be sure those additions are a good idea or not.
This would be more like a way to spend Bitcoin on websites and services where Bitcoin is not accepted directly.
For example of gift cards there are websites like thebitcoincompany.com, bitrefill.com and maybe few others, that can be used to purchase this cards without kyc.
As for debit cards there are both kyc and no-kyc, virtual and physical, some of them are issues by centralized exchanges or other by companies.
Few examples I found in bitcointalk forum:
