Released today and based on the crowdsale doc: "(ii) Airdrop [5% of OMG issued] : We will airdrop 5% of OMG tokens to ETH stakeholders, as a means to encourage incentive alignment with the Ethereum mainnet, with which the OmiseGO chain will
have a symbiotic relationship, and which will promote the diversity and balance of our PoS network validators. Airdrop will take place after the closing of the crowdsale. It is by no means a way to solicit funding for the sales. Further information about airdropping can be found in the Explanatory Note & Governance Term
