For those who own (or owned) Ethereum on a external wallet "for example Ledger NANO S" you should be receiving free OMG tokens by now. For every ETH owned on the July 7th (time that the snapshot was taken) you will receive about .07 OMG per ETH in your wallet.
You can enter your Ethereum wallet address here (https://etherscan.io) and select the Tokens transfer tab
Remember, you don't have to do anything, don't share your private keys with anyone because you will get scammed.
