Sarah was able to use her Swagbucks earnings to pay for her textbooks and even treat herself to a weekend getaway by filling out surveys & watching videos in her spare time. Mike, a stay-af1 visa refused slotst-home parent, is another success story. He started investing his spare change using Acorns. Mike didn't have to invest a big amount of money up front because Acorns' automated investing features allowed him to gradually accumulate a sizable investment portfolio. With the continued advancement of technology, earning money without investment appears to have a bright future.
