after all, it is approaching LTC
It's approaching the current LTC which is a dead coin walking at -95% or os from its peak.
if coin is premine/instamine etc
If a coin is announced as a premine that's one thing, but the instamine is carried out in a deceptive and misleading manner in order to make the coin appear to be (more) fair launched that is something else. And as you say it goes to another level entirely if it is launched in a deceptive and misleading manner and then the parameters are changed to the benefit of those involved with the instamine.
Catalog of at least some of the deceptive and misleading statements by Evan that facilitated the instamine (supporting references for each are there if you click through):
In addition, the DRK FAQ claims that the 2 million coin instamine happened over 48 hours, and this talking point is also frequently repeated by DRK supporters. However, this grossly understates the severity of the instamine, and perhaps paints a picture of a short mining period over which outsiders could still realistically decide whether or not to participate.
In fact:
1. Within the very first hour over 500,000 coins were mined
2. Within 8 hours over 1.5 million coins were mind, which is most of the instamine.
On the matter of the instamine itself, to focus on the amount of the instamine and the subsequent disposition of the coins is to ignore a whole host of extremely deceptive and arguably fraudulent practices that surrounded it:
3. That Evan misled people into thinking that the launch would not happen for days (and specifically "definitely" not in "hours"), then it happened in a few hours, late at night in the US and during the early morning hours in Europe. Considering the >500K coins mined in the very first hour alone, the effect of this "ambush" was enormous.
4. That the stated reason for delaying the launch for days was to do more testing and fix bugs. Yet when the coin was lunched it still had a "serious error." Why was the rushed ambush launch done in this manner?
5. That Evan withheld information about the purpose, features, and goals of he coin development until after the instamine was complete. It was absolutely impossible for you to have any reason to mine this coin unless your strategy was to mine 100% of new coins that were launched, you just happened to stumble into it, you were friends with Evan, or you were Evan. In effect it turns the instamine into a premine, because the coins were mined before the coin was properly announced.
6. That various changes have been made to rewards, etc. multiple times., always in the direction of reducing/restricting/locking up supply, to the benefit of existing holders. The latest version of this is masternode payments, which look very much like a HYIP (a form of financial fraud which attracts new investors by offering high yields to the benefit of earlier investors)
Now it is possible all of this was an accident. If so, you are asking us to believe in a string of extraordinary coincidences all apparently (by sheer luck) benefiting the same party or parties.
If it is instead not all an "accident" then it is evidence of deliberate fraud on the part of the person or persons still involve with running the project. That is certainly relevant and troubling information, even if the nature of circumstantial evidence (even strong circumstantial evidence) is that it can't be 100% proven. Things might be different if there were a complete and transparent change of leadership (as for example with BitMonero->Monero, and probably some other coins). But that is not the case. The person (assuming, not necessarily with certainty, that he acted alone) responsible for everything reported above is still there.
None of this proves it was not an accident, but given the fairly strong circumstantial case, I'm going to not only stay away, but advise other people to stay away.
