The key result of this analysis is that we should not expect the current exponential growth of bitcoin prices to last more than 36-48 months - even under the most bullish imaginable scenario. Buy sooner rather than later is my obvious conclusion.
The speculative bubbles always see a blowoff top, which is characterized by steepening slope in the price curve (ie. "going parabolic" instead of just "exponential"). In this sense your curve can only be correct if we expect an overshoot of a hefty magnitude over the trendline. In 2011 the price reached 50x the trend, last spring 4 times, now we are already 1.3 times. If the final bubble is a mere 10 times the long-term valuation, we are talking about $50 million per coin. If otoh your line is used to predict the bubble top, it is drawn incorrectly from the general price trend.
If your point was to say that after 36-48 months we will start the ascension to Alpha Centauri, then we certainly agree, and the most sensible timing for purchase is NOW.
