Due to changes in the banking laws, when you put your currency into a bank, it is no longer yours and they do not really have to give it back on demand (read the fine print). You are investing in that bank and are taking all the risks the bank takes, including over leverage and derivative exposure. If they fail (and all will sooner or later) they can seize your funds for a bail-in.
Credit unions are marginally better, but but do seem to operate for the benefit of their member. However, they can fail too. The difference is academic when your currency purchasing value is zero.
