Hi Sophie,sophie wrote: I've wondered the same about the Perth Mint, another government institution that I'm investing with directly. They also don't promise to make you whole if they get hacked, but they do have a century-old stellar reputation for international investing to maintain. And, they make it nearly impossible to change your linked bank account, so I imagine that process would be difficult to hack. Neither of these is true of Treasury Direct.
While this is a cash discussion, with the Perth Mint you can have the account set up so it requires a phone call and a security code to make any changes. All transactions are recorded via "old school" letters in the mail. Thats how everyone I know does it.
Or maybe I am too old
