Remember the security rules! Create a new e-mail & password for airdrops. So, when airdrops ask you for private information use the airdrop e-mail & use a unique password for every airdrop. For example, you can add the first or last letter of the token (in this case C) after your password.
For every extra referral you get 50 IOX tokens extra.
