What are all basic requirements for an airdrop account...Do we need some money or Ethereum in wallet in advance to participate in airdrop campaigns?
there many airdrop out there with different rule, mostly you only need to provide your ETH address and follow their twitter, liked their FB page and join their telegram channel.
but there also some who required you to have a minimun amount ETH balance in your wallet to prevent people using multiple registration by using new ETH address.
