The high interest to be paid in a very short period could mean a lot of trouble for some borrowers. Remember that a vast majority of those who resort to these loans have had difficulties with their finances already, or else they would not have bad credits scores. It means that the borrowers might end up unable to manage the payments for what they have borrowed. They might then be forced to borrow again or to extend the loan. In short they might end up in a cycle of taking out quick cash advance loans to cover for all of their expenses. It would be very hard for them to get out of that situation in the long run.
