Difficulty adjusting algo can be changed to counter multi pools. Its called "anti multi pool patch" or "anti flash mining patch". Some scrypt coins already have, DOGE will get it sooner or later.
With multi pools stopped, DOGE value will raise.
Exactly this.
By 2015 the price could be 1000 a coin because no new coins will be produced, the multipool miners are in control of the price now, meaning it will keep going on a downward trend until
the block rewards are finally halved. This occurs around April sometime.
