Although analysis of a single factor and cryptocurrency combination, as above, is of interest, more general findings across multiple cryptocurrency/factor combinations can also be pursued. Fig 7 shows, for each cryptocurrency and factor combination, the mean coherence values during the bubble and non-bubble regimes. Each horizontal subplot shows a different coherence period band, from the lowest period band (2–4 days) at the top to the highest period band (256–512 days) at the bottom. As the duration of data for each cryptocurrency varies, certain ranges are left blank when that cryptocurrency does not have enough data to produce values for such bands.
In order to provide a methodology to detect bubbles in time series, Phillips, Wu, and Yu [23] proposed the supremum augmented Dickey-Fuller (SADF) test. This applies a series of right-tailed unit root tests to expanding windows of a time series (with a fixed start date), defined by where r2 is the final data point to be considered in each window, starting at r0 which is a fraction representing the smallest allowed window size and expanding to 1(the complete data set).

But while it’s based on sound, democratic principles, cryptocurrency remains a technological and practical work in progress. For the foreseeable future, nation-states’ near-monopoly on currency production and monetary policy appears secure.
Altcoins also sometimes differ in the method of verification used to authenticate transactions. While some altcoins use Proof-of-Work systems, others use Proof-of-Stake consensus, which replaces miners with validators. Proof-Of-Stake mining requires a lot less energy and fewer resources than Proof-Of-Work systems since Proof-Of-Work miners have to do much more ‘work’ to mine blocks.
