The role of cross-border remittances of crypto stablecoins in the Russia-Ukraine crisis?

What if all the banks in Ukraine and Russia lock their accounts? Their currency depreciation? And they are taking refuge in another country?

Bitcoin, ETH and other digital currencies seem to be quite easy to replace this, they just need to bring their phone or their private key with them. But their weakness is: price volatility. If a guy goes out of their country and they buy BTC for 40k/1BTC, when they arrive in a 3rd country, the price of BTC is only 30k/1BTC =>

The use of stable is quite suitable for this (for those who like to be safe): USDC, USDT, BUSD … too many options.
