Awesome! This project looks very promising, and the OmiseGo team looks very solid. While an airdrop might temporarily depress prices, the longer-term impact is likely to be positive, as it spreads awareness about this project and gets people directly involved in it by simply having ethers in a wallet.
Great idea.
When is airdrop scheduled? How can I get free coins?
This is a quote from their webiste "sometime quite soon (TBA soon), every address on the Ethereum blockchain that held a balance over a minimum threshold of 0.1 ETH at a recent past block height (TBA soon) will receive a share of this 5% that is proportionate to their share of ETH." Just visit their website daily cause they will announce the airdrop schedule soon.
