The only coin I own under $0.05 is FunFair.  It's a platform to develop gambling sites.  No particular reason why I can justify owning it, like you, I just wanted to take a swing at something where I buy a lot of it, and hope it explodes, and it seemed to fit the bill.

My next two lowest cost tokens are BAT and 0x ... both under $0.20.  I'm losing faith in BAT but I think 0x could be big.
