The purpose of this airdrop event is most likely to boost its crypto donation from the crypto community. Personally, I'm kinda curious how would the airdrop going on since we all know donations are coming from multiple chains.
On the other side, I feel sad for people who make donations and expect something in return.
Question: I was looking at their thread, they accept BTC ETH and DOT, afaik.
No, at the first they only accept BTC, ETH, and USDT (both erc20 and trc20)
Then from 1st March they begin accepting DOT donations
