Some comments and suggestions:
1. Sending ETH to the contract complicates the airdrop process. Why not just ask for info required via google forms/docs? Plug it in your contract then you've distributed AUT.
2. Why do the participants need ETH? Is autoria tied to eth aside from being a smart contract like everyone else doing an ICO?
Why not just ask for an active ETH wallet meaning with 1-2 months activity. No new wallets will be accepted on the date you prefer as cutoof. Doing this proves that the wallet user already an eth user - Proof of ETH.
3. Why not distribute it to first 300 users first with initial distribution of 40,000 number.
2nd week 30,000, 25,000, 20,000, etc. Up to dev team which is a better number for distribution.
4. Set rules, if the wallet loses 20% while the airdrop is ongoing, automatic disqualification from succeeding airdrop. This way, you prevent massive dump.
5. Last and the most important, what will AUT be useful for? What other practical real world services will be built on top of AUT?
These are just my suggestions, the community may have a better suggestions as well.
I agree, project sounds good. I am not a techy guy and def not comfortable sending out ETH's in a smart contract assuming i will get them back. if there is any other way to proof the Ethers are mine i will be happy to do it!
