Without knowing anything about what is driving the price of these things, just looking at the graph this does not behave like a random walk. If I were investing, I'd buy a broad range of these when they're super cheap, and then use some kind of algorithm to tell me when to sell - like i.d. the peak value within some window of time, and when the price fell to 20% below that peak, sell it all (I'm sure there's a better way to do it than that even). Rinse and repeat and lolprofit.
