Most of the spikes correspond to specific events, like the marketing last month before the news about them talking at some conference (or more often just people trying to pump it for a quick buck).

Any similarities you find with graphs on other coins are coincidental, the price will probably keep spiking, dropping and slowly stabilising higher over time until it finally starts being used as a payment method.

At the moment DCR isn't really being used, the price is controlled by what people are willing to pay to invest in it. There's no point trying to find patterns in something like that.
