    Rating of project


    First, besides Whitepaper, there are also Full Desk and Lite Desk. Team members has lots of year working in the consumer industry. Thus, there are also advisors and partners. Taking the data form the crowdsale details, 12 % of tokens are in the reserve fund. it is good that the share is little. So, token rate will not be influenced when it enters the market. Furthemore, there are also bonuses for early investors. That served as a great motivation.

    Risks and disadvantages

    According to the Roadmap, it looks that the project has no plans after January 2019, no steps are mentioned on the website. A significant disadvantage is the absence of the working prototype.


    Overall, the project idea looks too difficult to understand without the alpha or beta version. In addition, investors can use not just only Ethereum, but also Bitcoin and other ways of payment.
