I'm still hoping we can have an honest discussion on nothing at stake!

Here Here..!
1) Much is made of the 'wasted' and 'costly' electricity used to run the POW mining rigs.. People seem to think this number can increase 'INDEFINITELY' and somehow consume ALL the power in the whole world. This simply is not the case. The miners will spend what they can make from mining, they can't spend more.. or go out of business. The Market will determine what this will be. Personally, I really don't see it as an issue, at all.
POS queries..
2) What if all the coins in a POS system are distributed evenly, yippee!, so that there are very few, if any, whales. Everyone thinks they have an insignificant amount, for mining purposes, but in truth they are ALL minnows. Who would mine ?
3) If 10% of the stakeholders mine in POS, since I think 100% or even 50% seems unlikely, does that mean you need 5.1% to perform a 51% attack ?
4) In POS, can energy be expended searching more chain branches to find a valid chain on which you make more money ? If this is the case, won't future miners just spend money and expend energy until they spend slightly less than 1 block makes (same as POW) ?

Good Luck NeuCoin!
