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.
If those who are participating in airdrops whether newbies or high rank members of this forum, reads a lot of information about scam and airdrops they'll know that majority of airdrops are scam and they will know how they all works, if they ask you to send funds to unlock your token, then you know that this is a scam airdrop.
I think no one will send money to get back the worthless tokens. And everyone knows that airdrop is free, if it takes money to participate in airdrop then I believe people will quickly give up it
