While fluctuations are expected, Noble says this swing is a bit out of the ordinary. “I thought the market was maturing and these things would be less frequent and severe. Boy was I wrong,” he says.
GURA: And Gensler is asking lawmakers for their support and for more resources. That makes Senator Lummis nervous. She's worried more rules will make the U.S. less competitive. And the crypto industry is also fighting back. So far this year, it spent more than $2.5 million lobbying lawmakers. Republican Congressman Warren Davidson believes Congress needs to make a decision about what to do with cryptocurrency and soon.

Long term relationships also strengthen, to some extent, around areas indicated as bubbles. The previously observed long term relationship between Google Trends and Bitcoin price [8] can also be seen here, between late 2012 and 2014 (period band 64–256). With the benefit of extra data it can be observed that the relationship disappears around 2014 (for lower period bands) and 2015 (for higher period bands), before the relationships start occurring more consistently in 2016 and 2017 (a region with a number of bubbles identified). The previously observed relationship between Wikipedia views and Bitcoin observed in 2013 (64–128 band), disappears before again returning in mid-2016 and 2017.
We further explore the significance of cryptocurrency fundamentals at the aggregate market level using traditional asset pricing tests. For this analysis, we construct risk factors that are based on aggregate values of computing power and network. We denote the aggregate computing power factor with ACP and aggregate network factor with ANET. The innovation in constructing these factors is that we express them in cryptocurrency return units following the factor mimicking portfolio approach (Knez et al. 1994, Lamont 2001, Vassalou 2003).
