Do you have a drivers license? A social security number? A phone number that you’ve used for anything else? Utility bills? Relatives? A car? Other large property?
Cash doesn’t mean shit unless you pay for everything in cash and never use the same info (including name, address, phone number, social, etc) for everything.
No car, no property, no phone number.
I don’t think a bank having my social security number is a privacy risk.
I do not give my name when I buy groceries or 99% of purchases. I don’t see your point.
It’s okay to be naive! The video talks about what data your bank has and how that gets used, as a security professional I know how all of this data is tied together plus the other data (assuming you don’t vote either?), and you don’t think there is anything tied to you so cool. Have fun with that. Keep pushing crypto.
