Safemoon has a few unique features that have attracted both praise and criticism. For example, the Safemoon smart contract charges a 10% exit fee for holders who choose to sell.

Bitcoin and other leading crypto coins experienced a significant drop in share price after investors began dumping mining equipment as China announced fresh regulations.
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.
