So if a person earn 1 bounty token, and invested 10 ethers, he is not eligible for the airdrop?
You are only eligible for the airdrop if you had a registred Eth Address during the Token Sale.
What is eligible is your address, not the owner. If you move the tokens to another address, you will not receive the airdrop.
The airdrop is calculated based on the lowest balance on the month. If you sell all and buy back, you will not receive it.
Maybe your bounty address is eligible, but i dont think so.
The airdrop is very small, last one was 0.87%
