LUTZ @ all the people crying for an exchange. You want one make a dang google doc then. Coins used to go a few months before they got pegged onto a exchange. Giving a coin a week or more to see if its worth while does nothing but help the price because this helps avoid typical scam pump and dump coins.
By not having an exchange during mining we also avoid Multipools
Well from my understanding you want a multipool when PoS hits otherwise it wont get mined, and you still need "blocks found" in order to keep the chain moving. Chain not moving=no trasactions getting processed
(more or less info for the newbs ... little more info on how PoS works )
