Assuming you are a regular person, and that you do not have the US Government out to get you, put your money in an FDIC (or equivalent) insured bank account. The financial system is pretty good at making sure that even with these hacks and breaches, the actual depositors don't actually lose money. Other alternatives such as hoarding gold, digging a hole in your backyard and burying cash, buying cryptocurrencies has a higher chance of resulting in your losing your money than if you just put it in a bank account.
