As long as they have 250k or less on the be bank they won’t lose their money.
Not necessarily true. Under changes in banking laws nearly a decade ago, banks can do bail-ins rather than receive bail-outs. Your deposits are converted to shares of a failing bank, and as the value of a bank falls, so does the value of your shares. The FDIC could take many months to pay out to depositors, in cash equal to the value of shares up to $250K. And this is a limit based on a total of shares across multiple banks owned by a single owning company. You can lose your money.
