Ignore that message ask you to sent ethereum and hey will sent more than three time your sending because that scammer, right now they have new way like ask deposit bitcoin on some wallet after giving email and password data, in their account have some btc and they ask to sent about 0,1 btc available to withdraw, that really scammer and better hidden your email and separated between your email join bounty and your exchange email.
I recommend using an alternative email address to register for the airdrop program or any form that requires personal email data, every email that has been given will be sent a bulk scam message and will interest you with instructions in the email for double profit the asset is sent to the scammer, if it is private email address is important then delete messages from scammers daily or weekly.
