We also want to add that we have another use case which may even surpass advertising demand.  This use case is tied to chat.newbium.com and is quite innovative.  Users will require NEWB if they wish to make announcements that send mass notifications to all Newbium chat users (site-wide notifications).  

Normally on Slack you can use the @channel to notify those on your team which maybe a handful of users or a large group.  In any case this is still much smaller than the total population of slack users.  Now imagine if you could target all users across every slack team with a general announcement that would greatly increase your reach and would be very valuable.  Unfortunate it would also generate much more notifications than there are even now with slack for example.

To control site-wide notification spam users will need to pay to use the function, they will have to pay in NEWB.  The amount of NEWB to use this function will not be as high per say but since many coins need to make important announcements then we foresee strong NEWB demand because of this simple use case.  

There are technically no limit to how many site-wide (mass) notifications can be sent but ad space is always limited due to real estate constraint on the site.
