Here's some speculatin'.
In order to know the potential for DRK to continue to rise, I'd compare it to the historical giant runs of the major coins like BTC, LTC and DOGE.
DRK is currently up ~500% in 20 days. I haven't thoroughly done the research prior but I am wondering what other coins have sustained these kind of gains and for how long.
Even if we are still in the beginning phases of recognition for DRK and the money doesn't flood out into the rising price of bitcoin, I would not be surprised to see some profit taking happen.
The one thing though, every time the price tests the "new floor" as was pointed out earlier, it springs back up into place.
If you look at the "long-term" chart of DRK on Poloniex its absolutely beautiful and it makes it look like we're about to surge another 100%.
It goes without saying that the real future of DRK depends on mass adoption and utilization, which will be required to support these price levels.
