Honestly nothing.

My problem is cash is really the only way to be truly private with your finances. Nothing else besides going great lengths using Crypto or gift cards is really private as far as I understand. I personally hate using cash, it is just such a hassle to use when compared to a debit/credit card. I always worry I don’t have enough or I have too big of denominations, or I will fail at math and look like an idiot. It is annoying to carry around, if you live in a bad neighborhood it could be potentially dangerous to carry around.

I really wish there was a private mainstream finance option but I have yet to come across any.
