Over the last month Monero has broken out over and held up at 0.003, while Darkcoin tested and failed to maintain 0.021.
Both resistance points are roughly triple their respective coin's monthly low:

Monero's gains are based on a sustainable staircase pattern of rises to new highs followed by periods of consolidation, driven by excitement about the immanent DB and a blossoming ecosystem of value-adding services.

OTOH, Darkcoin only enjoyed a brief blow-off top because of an ill-conceived rebrand that succeeded only in driving off vertoe, one of their last
three two core devs.
