With Dash that "market" is the mining community because they have to supply hashpower to the network AND a portion of the mining revenue. The incentive for doing that is that the NET value of their remaining revenue is increased due to the economic model as a whole supporting a high value coin.
I'm not disputing the price of a single DASH. BTW, there is an automatic relationship between the price of a single dash, the net block reward and the hash rate. Miners make profits from the moment that the hash rate is lower than the profitable hash rate.
I'm disputing the "market cap" of DASH. Most coins being locked in, this doesn't mean anything. If I make an alt coin of which I own myself 9 million coins, and there is 1 million on the market, if the coin is traded for, say, $5, then the actual market cap is only 5 million, and not 50 million dollars. Because the 9 million are not liquid. In order to maintain the price, the net mined coins need to be sold to "new money" (or my pump money), but that's peanuts. People *thinking* there is a market cap of 50 million, will not hesitate buying coins if it is on the rise, because they think that they will be able to sell a reasonable amount of stash without crashing the market. That's where they are wrong, because the actual market is much, much smaller than what they think it is.
