deeponion is one of the most successful airdrop before, it reached 18$. But now, I see abandoned project, since anonymity is not considered by regulator as legal. I hope it will recover once again.
Yes it was one of the most talk airdrop's that time and until now their airdrop distribution method is still being used in other airdrop projects.
They started it all and now other airdrop project follow their direction.
