> As you know if you read enough about banking, and as the intro points out, banks already invest your balance in risky stuff. When the bank screws up and loses 90% of my money, I'm guaranteed by the FDIC to get it all back (as long as it's under the insured amount). When I screw up, I lose money. Sure, that's the way investing works, but people generally separate "funds I can afford to invest/lose" from their day-to-day checking accounts. These days, you can just electronically transfer your money to your broker and it's available "instantly". I am not really seeing an advantage.
