Skewing toward small stakeholders don't work. We ran these rounds with Nxt before.
It would take me about 5 minutes to write a scrypt that can distribute my account into 10k chunks.
BUT, they all would have to be forging too. That's the catch, isn't it.
If even the need of active forging is not an issue, then it has to be something along these lines I suppose
