I don't quite understand the need for the token. Why not just sell shares that generate a percentage of the network profit to the initial investors and have the network power purchasable in BTC (or any coin for that matter)?
Because there are no future profits.
The payment on Zennet is directly between the provider and the publisher (bidder).
No middleman at all. No fees. We (nor others) don't make a dime after the Genesis block is out.
In addition, using existing coins is impossible due to technichal reasons (also discussed on this thread).
