If, over the last several months, you were dissuaded from investing in DRK because of people complaining about instamines or "centralized" masternodes, then you lost out on huge investment gains.
This is obvious in retrospect, but it always amazes me to hear people rationalize why DRK shouldn't be so successful, or that it doesn't deserve to do as well as it is doing. If Google stock suddenly skyrocketed in price, I would roll my eyes at any financial expert who wasted his time trying to rationalize why it didn't deserve to do well, or why it should have failed. This is fanboy behavior, and while fanboys might be great for watching sports or playing video games, they are terrible at deciding investments.
A smart business person leaves her biases at the door. If a company or stock succeeds, she analyzes what it did right and invests accordingly. If a stock performs poorly (e.g. *every* other anon coin in my portfolio - not naming names), she analyzed what went wrong and guides her future decisions accordingly.
DRK has amazing fundamentals - others have mentioned the professional, innovative, and prolific development team, Darksend, InstantX, the great and growing community, etc. I will only add that the system of masternodes is an elegant way to maintain natural upward price pressure.
No other coin currently has this. Over 2000 masternodes means over 2 million DRK removed from the supply side. Everyone who wants to buy a masternode is also adding to the demand side. DRK owners who don't own masternodes benefit from this scarcity and upward pressure passively, as their DRK steadily increase in value.
If you have a knee jerk reaction against DRK based on a few oft-repeated talking points, you are doing yourself a financial disservice. Only results matter, and DRK has consistently delivered.
