Bitcoin ATM Scam the victim receives a call or message from someone posing as a bank fraud investigator or official, claiming that there is suspicious activity linked to their accounts. They urge the victim to withdraw cash from their bank account to "protect" their funds and then instruct them to deposit this cash, bill by bill, into a Bitcoin ATM usually located in a convenience store and used most often by illegal aliens sending money back to their home countries.

Your bank has an interest in protecting you from scams like this as a sudden withdrawal impacts their own cash reserves and requires expensive (for them) shifts in earnings vehicles.
