Bigworld, Wow, with that much dough coming in, there's no need to take unnecessary risks. Just sock the money away in safe investments, and you'll soon be rich.
The only way to mess things up would be to fritter it away on risky trades and speculation, things like shorting, options, or loading up on one investment or sector. Taking huge risk is for when you are poor and trying to amass the money. Once you have it (as you do), you have the luxury of being conservative.
