Erm, currency is the term, and it's a laudable goal, but we're not there yet. Most look at cryptocurrencies as a a hedge because of different monetary policy (eg Bitcoin), censorship resistance, or other features (Ethereum).
Bitcoin has been a great hedge for those who can access it in Venezuela.
Which is precisely why you don't leave money sitting in a 0% savings account. You invest it in equity, not a currency. Fiat is designed to lose value through inflation. Thats how the system works.
Expecting to hedge against inflation by dumping your money in another currency is insanity. The only way is through actual economic growth.
