This situation goes to show the utility of bitcoin as a borderless currency which is immune to regulations, sanctions and the other games of politics and more people would come to the realization of this through such public acts.
I however sometimes wonder how many of the donators are enthusiasts of the cryptocurrency they donated in, or if they simply googled "how to buy BTC, ETH etc with credit card" and would not be interested in looking it up further.
Lets suppose its true and people will realize the importance of bitcoin. In the situation o war, bank and credit cards (plastic money) stopped working. Only cash and crypto in ur personal wallets can be handy all the times.
Cash would have more utility is such a situation as it is the fastest means of transacting and is not dependent on internet connection or access to a mobile device.
