I’m sure a lot of people might start out that way. But if you get free money for parking your cash there, why not use that money to dabble in some trading? Seems like there is little downside for the company, and potential for upside for the consumer. Pretty good acquisition strategy, in my opinion.
Alternatively: If you get free money for parking your cash there, why risk that money by trading? 3% guaranteed earnings is a very good deal without any downside, while the risks involved with trading that money are substantial.
Also, presumably lots of people would rather put their beautiful minds towards things other than being anxious about how their savings are going. There is a lot to be said for just being able to park your money somewhere and not have to worry about it while you go live your life.
