Ask HN: How do you invest a spare $50k?

Under no circumstances should you invest in options. Options are risk hedges, not investments. You can't make money buying options for the same reason you can't make money buying insurance. (You can make money selling options, just as you can make money selling insurance, but not as an amateur, and not with a piddling $50k in capital.)

Index funds are your best bet if you just want to put the money away and watch it grow without having to work at it. There are some other reasonable choices, like investing in your own education or startup. This doesn't necessarily mean paying tuition or hiring someone. It might mean using the money to pay for living expenses while you spend N months working on a project of your own. You will most likely not see a direct return, but you'll learn a lot, and you can leverage that knowledge in the long run.
