Lightcash Airdrop
Looks like they want to compete with Litecoin. Will be hard for them but their whitepaper, website and team looks promising.
If you make it under the top 1000 you'll receive 250 LCCT each worth 0.0002 ETH which are 0.05ETH or about $30. Not bad but I believe you'll get under the top 1000 only if you refer some other people. If you do so I recommend to participate, otherwise it's just a wast of time.
update: Not everyone receives the same amount:
1st place - 10.000 LCCT Tokens
2-10 place - 2500 LCCT Tokens
10 - 50 place - 750 LCCT Tokens
50-100 place - 500 LCCT Tokens
100-500 place - 250 LCCT Tokens
500-1000 -125 LCCT Tokens
