I haven't heard any solid word from exchanges about airdrops. Best to register your eos public/private keys to your eth public address. I followed crypt0 YouTube video and it was farily easy.
I encourage others to register. You'll learn more about eth smart contracts and get more familiar with keys, and it's a good quick learning experience plus all the added bonus airdrops happening on the Genesis block.
Do this soon like today if you got a lot of eos on exchange. Binance only allows 2 btc worth of withdrawals per day and coinbase allows you to send out only 10k worth per day if you want to buy more eos.
These airdrops can be worth a lot in 3 years if the project is good. For example decred. You can buy a sports car with those free airdrops.
