The long term positive coherence relationship observed between online metrics and price may be the result of another factor which we hypothesise could be technical progress. As a project makes technical progress, it is likely to have a community form around it over time, increasing online activity and also demand, and hence price, of the particular cryptocurrency. An interesting avenue of future work would be to consider the coherence between price and technical progress (via looking at each projects source code repository—these are available as cryptocurrency projects are generally open-source).
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 mining is raising concerns about its negative impact on the environment. According to the Cambridge Bitcoin Electricity Consumption Index, the industry consumes more electricity than the Netherlands and slightly less electricity than the United Arab Emirates.
A new white paper from healthcare analytics platform provider Healint shows that most patients with migraine and other comorbidities had positive experiences with telemedicine, especially during the COVID-19 pandemic. These findings were based on a survey of users in Healint's Migraine Buddy app, a highly rated headache and migraine tracking app recommended by neurologists.
