More broadly, the U.S. has been slow to issue regulatory guidance for cryptocurrency businesses. The industry has generally appreciated regulators' care and caution to avoid hampering innovation or overregulating something so misunderstood, but the lack of clarity has also become restrictive for many looking to operate, develop, and grow their products and services. But Zhao appears to be undaunted by that.
At each point information from neighbouring data is used. As the time series considered are finite, the areas at the start and end of the data (especially at higher period bands) will not have all the data required. One solution to make computation possible, chosen here, is to pad the time series with zeros where required. However, the zero padding will impact the reliability of the results. It is standard to use a cone of influence to represent this difference in reliability of results. Pale colours represent those areas outside the cone of influence with less reliable results (as seen on Fig 3). Higher period bands require more data for computation resulting in the cone shape.

Bitcoin took another step closer to mainstream investing Tuesday with the launch of a new security on Wall Street tied to futures of the cryptocurrency.
