Statistically, it's very unlikely that Darkcoin adds much to its valuation from here ever again. If it did it would be a exception and it won't be because it has the best technology. Being in front "technologically" does jack to a coin's valuation. There are loads of coins which have way overtaken Bitcoin, Peercoin and Litecoin technologically but haven't even put a dent in their price.
What coins do you refer to here as being technologically superior to Bitcoin? I know that there are lots of coins out there with features like smart contracts, POS, smart property etc., and some of them may succeed. The main difference between them and DRK, is that DRK has just focused on improving one feature people already like about Bitcoin, anonymity, and it works right now.
