a) You should use log scale[1]
b) The same "hype cycle" has been repeated in 2011 (bottom $0,001, top $32, crash to $2) 2013 (bottom $10ish, top $266, crash to $55) and 2014 (bottom $70ish, peak $1200ish, crash to $350ish) - always reaching higher highs and bottoming out to higher lows.
Therefore, zoom out and you will see that Bitcoins has "interim bubbles", but the long time trend has nothing to do with Gartner's hype cycle.
