I think this condition "Own at least 0.01 ETH on the Ethereum address specified into airdrop module". should not be , because most people they do not have money in ther wallet, it is kind of you to help them so as to like your project ans spead it in all over the world.
i think the measure of atleast 0.01 eth is okay we see people having as much as 10 eth address this will curb them to a large extent
