So Say some one Makes a new market every time right and Just keep stacking up the coins and they never get used or moved. Could you limit the supply of btc in circulation? Would this cause a price raise? or would it cause btc to drop? I Know a size able amount of money flows though these markets and btc has a set cap where it stops paying out right? a totally number of btc dished out? If this could be done is this what is going to happen? and do you think markets will switch coins or will they just be come a Money pit or get rich quick dream.
Not possible for various reasons.
This question is better asked at the bitcointalk economics board.
