One of the things that Naomi recommends regarding financial data security is zero knowledge proof cryptos. Transactions via such cryptos are not reported, and cannot be connected to your person if you don't deliberately connect them to you. I think as long as such cryptos are possible to use, it is a good idea to use them for such transactions as are possible to use them for. Have a watch at this ~hour long video. It just may change how you do everything you do.

Dear @valued-customer !
How is Zero Knowedge Proof Cryptos different from ordinary cryptocurrencies?

I do not currently use cryptocurrency, but I agree with your claim.
