Using Stable Cryptos as a Hedge against Inflation- Is it (relatively) safe & practical?

The local economy of our country is doing poorly & inflation is getting worse everyday. I thought maybe I could convert my local cash to a decent stable coin (preferably tether), to stop the inflation eating away my savings & to potentially have access to foreign markets. What are your thoughts on this? Is it safe & can it work in the long-run? Is it even doable for someone in my position? Also noticed some crypto exchanges offering savings schemes with 3-4% apr,are these worthwhile? Thanks in advance.
