Facebook’s closely guarded Libra project could be the first true cryptocurrency alternative to fiat currencies, although its growing pains suggest that true parity remains well in the future.
Cryptocurrency is a good investment if you want to gain direct exposure to the demand for digital currency, while a safer but potentially less lucrative alternative is to buy the stocks of companies with exposure to cryptocurrencies.

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.
