I think it would be better to get GPU to mine DRK rather then invest in Masternode. There are too many unknowns with Darkcoin, you can have malfunctions/bugs that can render the anonymity useless, you can have government issues, the list of potential things that can go wrong is too long at this point. Better to get more GPU to mine DRK rather then putting money in DRK masternode.
I'm not sure on the Masternode thing. Definitely speculative, and doesn't really fit the "coin farming" aspect of this fund. And there are probably dedicated masternode pools for people wanting to invest less than the 25 BTC or so needed for 1000 DRK. If darkcoins are going to catch on, and maintain their value beyond the next few months, then this has good potential.
Has anyone looked more into DRK to see how strong the app/tools development is going? People need to actually use these or it seems like it'll all collapse in.
The things is that even if the is a risk, the ROI is really good (for now). So it is a "relatively" good investment.
