Short answer: You can't. Inflation (by gov. money printing) is a form of taxation for everyone who has money, deals with money or deals with businesses that deal with money. That means everyone. You are going to be affected, period.

Certainly, you can reduce your exposure to USD; but it is already a dumb idea to hold USD for too long. However, don't panic reduce your USD exposure and instead expose yourself to risks that you cannot assess.

There is yet an asset that holds against inflation. (ie: goes up when the $ goes down but never goes down by itself) Such asset will be highly complex and highly in demand that it might even incur a small inflation (discount) itself. We are, after all, in a world where all currencies are inflating at best and hyper-inflating at worst.
