Maybe worth mentioning: 2013 and 2014 bubbles had higher interest from the www in general - and marketcap is much higher now than it was back then.
Currently interest in btc is half as big as it was on the peak in 2013/14 and only 2/3 from the bubble in early 2013.  
Look, Litecoin had much higher interest in 2013/14 than Ethereum has now.



Don't think there's no risk. It might be overvalued already. Ethereum and LTC certainly are overvalued aswell as ripple, nem and many other alts.
