As a large investor in Darkcoin who watches it very closely, I can tell you the primary problem.
The network is not stable without centralized reference nodes. It's that simple. Yes, there are other issues that need rectified, but that is the primary one.
We've been waiting for months and months for Evan to fix it and as of yet, he has not. I haven't bought a Darkcoin in a long time because of this but have certainly sold some. InstantX is awesome, but without a stable, decentralized network, it's useless.
When Evan finally gets it fixed, THAT is when the price of Darkcoin will finally go up and stay up.
What is interesting however, is the fact that Mr. Spread and Spreadcoin may beat him to it.
And I honestly believe that he will. Evan has done a great job, but his methods are clunky and verge on being outdated.
He will. The question is, will it be too late.
From a financial perspective it really doesn't matter to me either way because I am heavily invested in both coins. But it's sure going to be fun to watch and I'd love to see Spreadcoin do well.
I don't think that'll even affect the price when the reference nodes are removed.
People simply don't care about that.
What you need to separate is the people who are emotionally invested in Darkcoin from those who invest objectively. It's hard, because the emotional investors are invariably the most vocal and we're all prone to selection bias (hearing what we want to hear). In the eyes of emotional investors, Evan and Darkcoin can do no wrong. They will cheer when Darkcoin does well and support/defend it when it does not. They will ride Darkcoin to the highs and they'll often hold the majority of their coins no matter how low it goes. They will engage in cognitive dissonance like no other and often go, "All in". While these type of people are important to any asset, they are what are often referred to as, "Dumb money". Very few self-made investors fall into this class. I've found that quite a few people who have inherited money fall into this class, however.
Then you have your objective investors. These are the people who will not only kick the tires but check the tire pressure and bring in outside experts to provide them opinions on an asset. They don't allow themselves to become overly emotionally invested in any asset. These are your investors that will invest when your fundamentals are strong and kick you to the curb when they aren't. It's nothing personal, it's simply logical business reasoning to them.
No objective investor is going to put a large sum of money into a coin that bills itself as anonymous when there is a centralized reference node and network instability without it. And these are the people that would take a coin like Darkcoin to its all-time highs.
Want to know how to become an objective investor? Take a deep breath and exhale (this is important as it activates your parasympathetic nervous system) and observe your reaction. Observe that your initial REACTION to what I just typed was that it was bullshit and to immediately figure out how to prove me wrong or roll your eyes and ignore what I said with no additional thought. Observe that and then play devil's advocate with yourself. Ask yourself, "What if he is right?" and go from there. Learn to respond instead of react.
