I recently found one project called Ethereum Meta, it is related to anonymity and untraceable transaction. They have a very interesting project to build the Anonymous E-Market Place.

I already joined their AIRDROP !

They are on Pre-ICO stage right now, you can check their website: https://ethermeta.com/
Or even better go through their Bitcointalk thread and find more info on AIRDROP: https://bitcointalk.org/index.php?topic=2659058.0
