Mitigate what, the value of your savings from being debased through money printing?
I'll assume that's your question in this response. Unfortunately there isn't a straight-forward answer, everything (precious metals, stock market, bonds, etc.) is more volatile than holding cash, but your cash is guaranteed to go down in value over time due to money printing, so you get screwed if you do nothing.
There are too many permutations and personal situations to offer a one-size-fits-all solution, but I'll offer some general guidance.
If you're just starting your career, and don't have much to invest, you should just focus on becoming the best in your field, take advantage of any retirement matching that your company offers, and invest it in low-cost broad market index funds (like Vanguard's S&P 500 Index Fund VFINX is one example). Most people who don't have very much money worry about what to do with their money when they would get much better returns just by focusing on improving their skills!
If you have money to invest, you should read about value investing, I'd start with The Intelligent Investor by Benjamin Graham. Even if you don't want to manage your own money (and most people shouldn't unless it's going to be their full-time job), it will give you a great foundation for understanding the financial markets and how to evaluate people who you select to manage your money.
