If the PoW will be closed, we can attract miners without suffering from the negative effect caused by mined coins dumping. Take a look at Blackcoin, when the PoW phase was over, the multipool has come that allowed miners to "mine" BC this way: miners are actually mining some coins from coinwarz top, that is exchanging into bitcoins, and then bitcoins are used to purchasing BC.
So, multipool purchased much BC every day, and the price went to the moon. Of course, part of miners were dumping BCs after getting the payouts, but multipool soon purchased them back It was a nice ride, and even now when the hype around it is over, the price is still high!

Why not to make the same with Nyan? It will work! And everyone will like it - holders will have havier bags, miners will make good profits mining coin with increasing value, and the speculators will enjoy rollercoaster ride. Much more new people will be into Nyan, so this will be huge win for every one in the community I believe.
+1 Multipool is very important point.
May be we have +10-20% coins per year and 5% later.
Max Coins: 1,000,000,000
(20,000)(1/√(Difficulty+500)) from block 7001-250,000
(15,000)(1/√(Difficulty+500)) from block 250,001-500,000
(10,000)(1/√(Difficulty+500)) from block 500,001+
WTF?
Many miners is dumpers. They sell coins at once.
