I have been seeing more and more projects holding bounties and airdrops post ICO. Not sure what it's all about but it appears to be a new trend. Any yes payout is always a pain with bounties/airdrops. It's always something.
Any examples? I think one reason why there's less airdrop programs after ICO has ended is because of transaction fees associated with transferring tokens, which doesnt occur when minting tokens to addresses on the ICO smart contract.
