What terrible advice in this thread - bitcoin, single stock/industry portfolios, gold, overseas real estate, option trading etc are all highly risky investments. I suggest to read "The Elements of Investing". It's a quick read and will help you have a broader (and more sane) perspective. But in general, ensure sufficient diversification and time horizon, then add more over time. If you're all in one stock - diversify asap.
