I’m kind of surprised you trust someone with your money that has 0 backing? What happens if Fidelity screws up? Especially as turbulent as times are, is the little extra on that investment in liquid funds worth it?
Best check what Fidelity is doing with the $. If don't get my money back , FDIC coverage @ bank isn't going to be worth much either. Will take my chances rather than let a bank screw me over on what they pay on deposits.
