I do, but ammount is not material significant. Is better to buy some on exchange for fiat. Well if only you own a lot lot lot of Ethereum like some Corps Hodlers do.
For 1 ETH in your wallet - how many OMG you received?
I suppose the airdrop is the same to all ETH holders who have >0.1 ETH proportionally their wallet balance.
5% of the OMG is allocated to the airdrop. The owners of the Ethereum receive a very small part.
