This chart shows nothing interesting and is hardly scientific. Of course by lining up price charts of various speculative bubbles they will roughly line up. The chart also intentially discards the first 4 years of Bitcoin trading data (2010-2013) where Bitcoin has actually gained the most. None of the other assets in the chart even remotely compare to Bitcoin's gains in these 4 years. Also, it should really use a log scale: http://bitcoin.zorinaq.com/price/
