As per their telegram group information they mentioned that if you are holding 100 EOS on Metamask then it will be automatically airdropped and you don’t need to do anything but if it’s less then 100 EOS then there are certain steps to do (you may follow telegram group for further update).
In Metamask it should show under tokens tab. If you have already registered your EOS on ETH address then your EOS is already started showing but if not then you have to do it manually (Steps mentioned on EOS.io website).
I hope this will help you. Thanks!
If I'm holding on binance will I get?
I am not sure about Binance whether they are going to support or not. For safer side it’s better and recommended that you always keep your coins in your wallet. For airdrops you need a public key which only provided by wallets not exchange. So try to move in MEW wallet and follow instructions mentioned in the post. Let me know if you need further help.
