Pay attention to the PlusCoin project. There is a ready-to-use cashback service for users and lead generator for business based on a mobile application with the cryptocurrency included - everything functions properly. The idea was successfully accomplished and it is developing, judging by increasing of partners number of the project and the audience. Moreover, the plans on the future on introduction of new functions and opportunities are also stated:
- P2P platform for exchanging goods and services for PlusCoin between users. Transactions are committed inside the service.
- Marketplace aggregator. A partner places the goods and a customer can purchase it for PlusCoin in the DS Plus online-store.
- Cryptoscoring tool can be used for crediting users to purchase consumer goods for PlusCoin.
I think it is very perspective.
