The token represents a share of the project. Its not a mandatory for skillchain to have a use case for the token. I think the value will come from the value and the utility of the platform.
As I understand them coins will be used to buy subscribe, purchase the domestic add-ons, etc. the value of the coin will depend on its popularity!
Well, I think this platform will be useful and can be good alternative for current job services. So token price will grow steadily with time!
