But to understand the dynamic that led to this year’s depressing year for crypto, we actually should start a few years before 2018. In bitcoin’s early days, Mt. Gox was the go-to service for handling transactions. Then, in 2014, it halted transactions and slowly copped to a crypto-hack to the tune of $473 million, the biggest hack of its kind at the time, and it gave many people pause. But it was still early enough for people to believe that the blockchain system was still getting all the technical kinks out.

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.
