I mentioned that in my post, and it is great advantage for me just for fact there is no KYC, and that means my personal data are not exposed. It is true that converting crypto in fiat via cards is very desirable way for many, but all your fiat transaction go through a bank or banks. Some often think that using cards can make them invisible to tax service, but card provider is using some bank, and you give all your data in order to use such service. It's the same as opening an bank account in some foreign country.
