well, i will give a small analysis of this coin, note the fact that i don't bullshit. i own 1% of the total coins currently in circulation, this same 1 % was at some point, not so long ago, 5 % of the total supply but because of the huge inflation rate (which is one of the reasons why this coin is not as valuable as you think it should be).
First of All, money is a tool of an economy, the value of the money reflects the power of the economy. As far as economics are concerned, this coin earns a big zero, no economic thought at all, it looks like another p&d coin.
Second, Deephash or the algorithm used, who really cares about it other than a small community of miners? i for one dont care about algorithms, and dont think it gives any value what so ever. This particular point will lead to a huge discussion, which will lead us to debate whether "decentralized" mining is really "decentralized" and the inevitability of "centralization" of mining, i mean bitcoin nowadays is mined by how many ? 4 or 5 wallets ?
let's skip this discussion and move to what i think any serious coin should focus at : "use-value". Let's face it, in the crypto-currency world today, we reached a point where we have higher death rate than birth rate. Dead coins are everywhere. Why? because of a rule set by lemonsieur ( which is moi ) :" Crypto-currency eventually returns to its intrinsic value zero". Now, for this zero not to be reached, you need use-value, and here lies the reason why most (if not all?) coins will fail.
Third, if you scratch the skin of 99 % of the coins on the market, you will find one thing in common, we want to sell for btc to the greatest fool out there. That's the reason you are here probably, and that's the reason the reader of these words is most like here too. This same reason can explain the utter economic ignorance of every single coin. Satoshi, who ever he/they is/are, an economic genius, and probably a historian too, because we are in an epoch of virtual money, so he/they designed an unlimited currency if you really think about it. 21 000 000, are in fact 2100 000 000 000 000 units of "value", 2.1 quadrillion units of value. So there is absolutely no reason for new units to exist on a separate block chain.
Forth, what does this coin really want? seriously what is the reason of existence ? the only logical ones i can give at this moment are the following : Proof of Concept for Bushstar and his friend, and few bitcoins reward for dumping the mined coins.
I think these are more than enough reasons why there is no price increase, or interest in dcn, even though i think most "traders" are driven by anything but logic, i can copy paste this to every coin out there, because it's the same everywhere.
what should be done ? I can't answer it, but 4.4 quadrillion supposed "units of value" currently in existence are just extra wasted bits of information in this seemingly infinite world of bits. what would Aristotle think of the value of infinity? most likely 0, but he believed than none of them really exist.
