Welcome to Nonfungible Tidbits. Our focus this week: Russia's war in Ukraine. 

In addition to uprooting the lives of Ukrainians and throwing the international order into chaos, the Russian invasion has created a proving ground for some of the most ambitious -- and cynical -- use cases for cryptocurrency. On the one hand, crypto has become a tool for individuals and organizations to provide charitable support and donations to Ukrainians (as well as a new frontier for online scammers). But there are reports of Russian oligarchs using the technology to evade an increasingly aggressive bevy of financial sanctions. We'll also look at the sale of an NFT of the Ukrainian Flag to support Ukraine -- a project backed by a member of the Russian punk band PussyRiot. 

Our other stories include scams trying to exploit donations to Ukraine, and how some cryptocurrency exchanges are handling the sanctions against Russia.

Cryptocurrency exchanges don't want to bar users in Russia

While the White House hasn't yet commented on this directly, Bloomberg reports the Biden administration has asked cryptocurrency exchanges to prevent Russian people and organizations from using virtual currencies to circumvent Washington's sanctions. Bloomberg cites a White House official saying that American authorities are aggressively fighting any misuse of digital assets to avoid sanctions. Reuters reports that Binance, as well as US-based Coinbase and Kraken have agreed to screen users and block anyone targeted by sanctions, but the exchanges have stopped short of banning all Russian clients. Binance and Coinbase are the two largest cryptocurrency exchanges in the world by market cap.
