A last-dollar scam is a type of fraud that targets people who need money. The scammer will offer to provide the victim with a solution to their financial problems, but to do so, they will ask for the last payment. The amount of this last payment will be relatively small, but it will be enough to convince the victim that it's worth taking the risk. The problem with last-dollar scams is that they are often very difficult to detect. The scammer will usually come across as trustworthy and well-intentioned and will make promises that seem legitimate. It's only when the victim makes the final payment that they realize they've been duped.
