If true this is crazy and no way a 20 year old has 3 encrypted bank accounts without outside help.
I hope to god all my bank accounts are encrypted.
Typically any online account is behind https (encrypted) and all the data on the volumes is encrypted and the drives behind the volumes are encrypted. Passwords are encrypted.
Servers holding the data might be overseas depending on the bank.
Wise offers seemingly easy international banking options.
The encrypted banking isn't the issue, just a herring.
The real issue, if any, is how much money is in there and where did it come from?
Encryption is still legal (for now) and ubiquitous.
