I'm assuming that you have limited investment experience, which is why you're asking this on HN, thus having fallen upon a windfall through inheritance, company stock options, etc. My personal opinion: do nothing. Do nothing. DO. NOTHING. This amount of money is psychological destabilizing, but even that will be nothing compared to when you are risking it. You have no idea how you will react if you start losing money (you might increase risk - that's how people blow their fortunes). If you're really looking for financial freedom, use the cash to take time off a job and start working on your own business. If you are interested in investing because you are interested in investing (unlikely if you haven't dabbled in that already), then start small. Take 25k and start buying stocks or whatever. Do not go big - it takes years of brutal experience to get even decent at investing. This is life changing money - in other words, your life has already changed. You don't need to multiply it to change your life. It's not worth risking it all. Go small, and just take time.
