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.
The urge to get paid and sell to Eth etc, is one of the reasons why most people ends up getting scammed because they tend to throw caution to the wind. There are many dead groups on telegram of which some were created for one airdrop or the other. As to add my own opinion, newbies should be careful of Airdrops that asks for private keys, ETH, or even to sign a message using private keys all in a bid to get their rewards; legit airdrops doesn't ask for these.
