I'm not actually one of the team members of MOBU. While I'm particularly passionate about the project, I have also been trying to get full understanding about some aspects of it too.

I'll give you answers based on the knowledge I already have concerning MOBU.

The security token you are talking about are tokens from ICOs who use MOBU blockchain for their launching. The security token is not the direct MOBU token.

The direct MOBU token itself is what I can call "the internal token". It is utility token not security.

MOBU will build a community where this token can be used and that is going to help improve the value. Also, I understand that they have a program that will retain people to the platform.

Hope my answers help.
Cheers!
