When it comes to the discussion of blockchain in relation to what's going on in the Ukraine, it's less about blockchain and more about the fact that they had an alternative way to facilitate payments. But this cuts both ways. When the world decides to shut off SWIFT in a massive payments gateway component, it is just as likely that those distributed crypto payments can be used to facilitate payments to or from Russia.
While there's a positive aspect in that you could use crypto to do some fundraising, I don't know that it is different from doing a classic GoFundMe campaign, or using PayPal. That didn't seem to be a big standout point. Many people who use blockchain see an opportunity to use the buzzword, which is something that cryptocurrency enthusiasts do all the time. But I don’t believe this was something that was unique to blockchain. It is just another mechanism to facilitate payments that cryptocurrency was part of.
