An ambassador system would be very helpful. A user receiving a HivePower delegation in the amount of 10k, 20k, 50k or any other amount proportional to their size on web2 for promotion would be a great alternative.
It would not issue more tokens to cover the costs.
Who would delegate, though? There's a cost to those delegating.
Maybe a DHF-funded HiveMarketing profile? That way the money issued by DHF would not be withdrawn a priori.
