I appreciate the effort but without more information this chart is of dubious value. What is the trendline based on? Unless it's based on stats and/or financial indicators then there's just too much room for curve-fitting and, effectively, useless.
There is no magic. The chart is average daily mtgox values, presented on a log chart with a least squares straight line (exponential, of course). Obviously the future is hypothetical, but this is the best fit projection using
known data.
