For me, I would recommend ETBS, Bitjob and ATS.

List:
1) ETBS (iTrade - first copy trading patform, beta due in March, low fees, supports p2p trading of cryptocurrency, profit sharing of fees every quarter to ETBS holder, very low total supply of 1.6m)
2) Bitjob( Something like Fiverr but completely decentralized and using the blockchain, enables students to bid for freelance work and earn some allowance, easy conversion of STU to USD, supported by Dutch Government)
3) Authorship(Authors have the ease to get their books published, publishers can easily locate authors who want to get their books published, translators can find popular books and translate them into different languages, and readers can access and buy a plethora of literary treasures – all at the same place)
