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.
An interesting avenue to explore is the wavelet coherence between different cryptocurrencies, allowing any relationships between different cryptocurrencies to be detected and documented. Relationships between different cryptocurrencies would be of interest for those searching for diversification within cryptocurrency markets, especially to those managing a portfolio of cryptocurrencies.
