I wrote about the Blue Whale a little while ago. It is the first Dapp to be built on the ICON platform. You can read about that here https://steemit.com/airdrop/@cybilbitgirl/airdrop-400-free-blue-whale-tokens. Their public sale, which just ended, was sold out in 10 minutes!
The good news is that the airdrop and referral program is still going on, so all of you who have not participated as yet please use this brief window of opportunity to get your 400 free BWX tokens.
I will be grateful if you use my referral link http://wwwbluewhalefoundation.ref-r.com/c/i/18449/9848308
