Founding investors have privileges specially in mining tokens, if you are lucky to be invited by one of the founding investor you'd have your chance to also have these privileges. All users of EOSex have privileges, if you own EXP tokens, you are part of the community and you are part of the company. You as a user can also invite anyone and receive 10% of all future trading fees generated by the invitee, paid out in equivalent EXP tokens.
this is a very interesting concept, and can invite many people to join this project, has the ICO begun? where can I find the EOSEX token sales site?
