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).
In fact, every newly created blockchain copy comes with a two-part monetary reward: a fixed number of newly minted (“mined”) cryptocurrency units, and a variable number of existing units collected from optional transaction fees — typically less than 1% of the transaction value — paid by buyers.
