Hi! There is the ICT airdrop. The only thing you have to do to get free coins is to write your Ethereum address and your Telegram nickname. Then you have to join their group and enter you personal code (group link and code you will get after entering your eth address).
It is four days event and it will be closed on 25th jan at 12 AM GMT, so hurry up!
