So he's selling Proof-of-Stake staking as a 'cloud' service? WTF?
Why would anybody choose to centralize their wallet on his 'cloud' service when you can easily download a PoS wallet and just have it running on a regular PC and staking as it should?
That's the whole point of PoS coins, to eliminate the need for constant PoW mining. It makes no sense to run a PoS wallet on someone else's server, unless you were trying to convince people you were selling them something they were quite ill-informed about and didn't realise the absurd nature of what was being shilled to them.
He probably will just create more coins to pay people out...there probably isn't any more staking going on than mining when he was selling hashlet to mine with. Essentially he'll just be inflating the coin. The add-on he's going to be trying to sell to people to get them to use the coin breaks every single retailer's ToS.
