If you are newbie and you are looking for ways of making some  Bitcoin and other altcoin, be very CAREFUL with AIRDROP campaign as many of them out there are out to scam/milk you with the little ones at your disposal. Sometimes, they are out to get your personal information like email address, etc and sell it out for money.
Some of them will tell you to send some amount of BTC or ethereum to their address as fee for you to get the aclaimed airdrop reward of which they will later run away and mute their telegram channel.

Be warn is to be armed.
