For the most part inflation threatens cash holdings and fixed-income instruments (such as bonds) which have not priced in inflation. Therefore in order to "hedge" against inflation you should reduce your exposure to such assets to the largest extent possible. But a crypto-currency is a high-risk investment, so using it as a "hedge" against inflation is unwise because you're swapping one risk for another (potentially) greater risk.
