Now I realized that minexcoin is for long term investment. This project is different with another ICO. It is like creating a new ecosystem. And it will need more time.
Could be true if they show real progress in development.
the only official information about devs are :
1-https://blog.minecoin.org/meet-minexcoin-team-advisors-and-partners-10a0c814843b
2-https://minexcoin.com/
according they have one android and one UI&UX Designer.
you can estimate how much time they need for a new ecosystem!
