...The bio of Kalush has a link to addresses for taking part in this thing.
It's too early to summarize the results of the auction, but I looked at the address for collecting donations and saw there only one payment in the amount of 0.0084 Ether. Given the fact that the charity auction will be held on May 28 at 19:00, most of those who wish will not be informed about this auction in time.
There are still a few days left, and I think they allow both crypto and fiat donations for the mic, so perhaps someone with fiat would be the winner. There are two transactions so far, both quite small. I think it was their big mistake to make crypto donations in Ethereum, and not in Bitcoin. While Ethereum is #2, it is much less popular in Ukraine and probably in other countries as well. Just to give an example of the difference, a
Ukrainian foundation that helps the army got 477 BTC of donations (currently almost 14 million dollars), but only 753 ETH (less than 1.4 million dollars).
Edit: I think they've changed the description from yesterday, actually, and now the mic is not for crypto donations, but for an NFT auction? Confusing and weird to make changes along the contest...
