MASSENA, N.Y. (AP) — A New York town along the Canadian border plans to impose a 90-day moratorium on new cryptocurrency mining operations to make sure local roadsides are not cluttered with trailers and shipping containers loaded with computers.
SAN DIEGO (AP) — A Los Angeles man pleaded guilty Wednesday to participating in what prosecutors called a “textbook Ponzi scheme” that defrauded cryptocurrency investors worldwide of more than $2 billion.

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.
