Vernam Airdrop
Vernam is a new generation of insurance process on the blockchain.
Their website, team and whitepaper is good. Just the airdrop is pretty complex and requires some time and a lot of data. In return for that you only receive 20 tokens (the maximum if you don't deposit anything nor refer friends). And there's a upper limit of only 200 tokens.
1 VRN is $0.085.
