I think OP is reffering to using BTC as a mean if doing transactions in and out of the country since most banks stopped working with russia so i guess it's a great alternative i mean that's why it was created in the first place.
Maybe OP is referring to bitcoin as an alternate, but considering the prevailing situation it is hard. Most of support systems has stopped functioning within and for Russia. So, even if someone wants to buy bitcoin this is going to be a big problem. Even the mastercard and Visa services have been stopped. What we can expect is a long term recovery after the war. There is no immediate impact to happen with Russia's economy even if it goes full on bitcoin.
