Well, I've been guaranteed with several scenarios:
Online mall: TokeMall
Exchanges:OceanOne, ExinOne, Fox,
Entertainment: Slotin, DICEOS, LuckyCoin
If you are a developer, you can extend its applicable scenarios by developing DApps. Its global online developer competition is still hotly ongoing, rewards are pretty good.
