I'm a bit skeptical too, especially with all the scam coins out. However, I got into the airdrop and so did many others. The 1 ether is meant as a donation if people wanted to support the project. You can buy it much cheaper on the exchanges. Considering the price he's asking for in the donation and only getting like 500 BLUE, there's a decline of how much he's offering out. In the beginning, I think he sold 147,000 BLUE for 1 ether, so those who bought into it for that much made profit so far. I'm still skeptical, but I threw a little bit into it just in the off chance.
