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).
Pips are the units used to measure movement in the price of a cryptocurrency, and refer to a one-digit movement in the price at a specific level. Generally, valuable cryptocurrencies are traded at the ‘dollar´ level, so a move from a price of $190.00 to $191.00, for example, would mean that the cryptocurrency has moved a single pip. However, some lower-value cryptocurrencies are traded at different scales, where a pip can be a cent or even a fraction of a cent.
