Enjin's platform enables the creation of unique digital assets on the Etereum blockchain. Assets are infused by any amount of ENJ when they are minted, which returns back to circulation when they are melted. 

The ability to create and track unique, verifiable, programmable, valuable, digital assets is very useful for game developers, but there are many other possibilities as well, which has attracted the attention of tech. giants like Microsoft and Samsung.

Infusing digital assets is one of the best uses for a digital currency that I can think of. If barriers such as scalability and fees can be overcome, adaption is inevitable.

(My opinion, not investment advice of course.)
