Actually this epic moment happened in Ukraine, I don't know how difficult it is to get cash there (even using e-money). Someone sells "a Legendary Car" with bitcoin.

If a person refuses to accept them and wants cash, chances that they will accept Bitcoin are actually pretty low. If you think that a 50 y.o. dude from Ukraine who only uses the Internet for Facebook and Telegram will be interesting in listening in a lecture about the benefits of Bitcoin while being in the middle of war trying to sell his car to the highest bidder, you are a bit unrealistic.
Still, it's nice that Bitcoin exists and is being used and is helpful in extreme situations. Just don't think that this is a common occurrence.
The assumption is that the buyers in this case are tourists (they speak English) who are trapped in a warring country and want to get out of the city immediately but there is no public transportation operating in the middle of the conflict. In this situation where cash and e-money are needed more by local residents so that the demand for exchanging foreign currency into local currency has reached the bank's daily transaction threshold (possibly over-demanded), I don't think there is an alternative currency to get something tourists need quickly except for a new currency which was just legalized.
