But why don't you find those beautiful airdrops once, whose only request was to communicate an address to receive the gift? 
It's not worth it now. Even if you find such airdrop, its value is going to be next to nothing when it reaches exchange (if it ever).According to be the most profitable 'airdrop' were that happened due to chain split like Bitcoin Cash. Hassle-free, just get your free coins. Miss those days...
