It looks like maybe the hryvnia has lost 5% of its value over the last year (and 12% over the last three months)? The bigger issue is that it's likely that Russia will overthrow its government before April (50% probability) and after that it's anybody's guess what the new regime will do with the hryvnia.

https://tradingeconomics.com/ukraine/currency says 29.7 hryvnia to the dollar at the moment.

I mean, I'm not saying cryptocurrency is a bad idea, but the hryvnia doesn't seem as totally pointless as you suggest.

According to https://www.cnbc.com/2022/02/24/ukranian-bank-suspends-e-cas... foreign exchange in Ukraine is mostly suspended though, and already was when I made my comment above, so the price in markets that are still open won't reflect what you see on the ground in Ukraine; the Tether price cited (32 hryvnia) suggests an additional 9% loss since yesterday, which does qualify as "free fall" if it continues.
