Yes of course . it make sense  to get  crypto  from airdrop because  you are not investing single penny  but you get coins worth of thousands. an airdrop usually  new, company is giving away  a certain  amount of coins or token to people whio sign up for the airdrop  with them. hey usually have a few things they want you to do, like follow them on twitter, slack and/ or telegram and share their posts with others or something similar.
