Ukraine is expanding the list of cryptocurrencies it will be accepting for donation amid an outpouring of support and looming humanitarian crisis after an invasion by Russian forces.

The country will now also accept Polkadot's DOT, the 11th-biggest cryptocurrency by market value, in addition to Bitcoin, Ether and Tether, according to a statement on a government Twitter account Tuesday. More tokens will be also accepted soon, the post said.

Ukraine has tweeted about a possible crypto airdrop - or promotional event that typically involves giving away free coins - saying "an airdrop has not been confirmed yet."

Bitcoin is up another 7.1% to $44,600 on Tuesday amid speculation cryptocurrencies will gain favor in the wake of sanctions against Russia. Ether advanced 7.4% and DOT is up 15% over the past 24 hours as of 9:15 a.m. in New York, according to pricing from CoinGecko.
