I only like airdrops that don't really require me to do much and don't ask for personal information.
One like this is https://pantos.io
The only requirement is to create an account on https://www.bitpanda.com and agree to the terms of the ICO.
I don't like to share personal information so I whenever they ask me for my facebook or twitter I just leave the airdrop.
If anyone knows of any more airdrops like this, please share
