I'm not convinced ...

Assuming people wont be carrying batteries around, then they need wires to transmit (sell/buy) electrical power. The power distribution/transmission operators already have products to pay people for producing power. Those companies will retain control of any pricing and profit on power. So for mass adoption, any decentralised trading system is totally dependent on the owners of the existing wired grids. Own the wires and you own the trading. Masses won't be disconnecting from the grid.  Why is this key point not discussed a lot more? No mention of it in their whitepaper. Government policy seems essential for Power Ledger to go big time. If this is a scam, then how far will the token price pump up before it crashes?
