Student loans aren't just for buying textbooks, No. 2 pencils, and apples for bribing teachers anymore. According to a recent survey, as many as one in five college kids may be using their student loans to cash in on the cryptocurrency craze. From a report: The Student Loan Report surveyed 1,000 current college students with student loan debt about whether they were asked whether they used their student loan money to invest in cryptocurrencies like Bitcoin and found that 21.2% of them have Sallie Mae to thank for their cryptocurrency investment. Many students borrow a little more money than is necessary to pay for tuition and books, according to Student Loan Report. The leftover cash is typically used for college living expenses, but some wily students think that investing in Ethereum or Ripple may be a better investment than a bachelor's degree in comparative English literature.
