I read the "How we make our money" page, and if I am reading it right, they only make money on the uninvested balances? It is free ($0) to invest and free to de-vest ($0, 0%), is that right? Seems too good to be true...

Also how legal is this company? I've read about small StartUps based on the stock market who then wind up getting in trouble with the FTC.

Honestly if this is free investment, then I might start doing some micro-investment. I am been put off the stock market by the overheads of investing/de-vesting (e.g. $20/trade). Although the hassle of filing taxes might still put me off.
