If you're over 80 years old and don't do online banking, but are convinced by someone calling "from the FBI" that your account is in danger, Wells Fargo will happily try multiple times to transfer your life's savings to multiple different Bitcoin bank accounts (the first few closed for fraud and funds returned) over more than a week and several visits, then open a new credit card and transfer the maximum cash advance electronically as you read the newly issued password out to someone on the phone in their presence, and never mention there's a danger in doing this or question your decisions, until all your money is gone.

How do I know? If you happen to have been a school teacher for 50 of those years, you keep excellent hand written notes of the events, that make your relatives sick to their stomachs.
