You have to be careful comparing these charts because, aside from the differences in fundamentals between the coins, the bitcoin chart is priced in dollars (a stable currency that traders do not generally tend to look beyond - ie "if I sell my Bitcoins here how many Euros will I get for my dollars today compared with yesterday") and the darkcoin chart is priced in Bitcoins (a volatile currency the dollar value of which traders check multiple times per day).
eh. I think you'd better think that through again
Some Monty Python logic going on there.I wish I could have the honour!

But no - the fact is that the difference in price denomination makes for differences in price behaviour. Just to give one example, if drk was ever to reach parity with Bitcoin you could expect some pretty important resistance right there. But what would the analogy be for Bitcoin?
