The current stake-based voting system is broken and unsustainable, because Curators invest time and get back around 15-20% of their vote value, while vote sellers invest no time and get back around 70%-90% of their vote value.

I see SteemPower as the base resource everybody needs to be active on the Blockchain. There will be a SP Delegation market for all these resource-hungry DAPPs like SteemMonsters, so the more SP you hold, the higher the income from SP leasing.
