“Where digital assets land, at the end of the day … will be driven in part by regulation, both domestic and international,” Former SEC Chairman Jay Clayton recently told CNBC.

Combining the BSADF with the GSADF test allows the r2 value to vary while still using a backward expanding window. r2 starts at the smallest possible window size, and moves one point at a time towards the end of the time series.
It can be observed that in the short term (2–4 and 4–8 day period band) there is no consistency in results; in some cases the null hypothesis can be rejected and in some cases it cannot. In the medium term there is more consistency in rejection of the null hypothesis in favour of bubble regime coherence values significantly exceeding the non-bubble regime values. In the long term, the proportion of instances exhibiting statistical significance reduces, with the majority of cases in the 256–512 band not being a rejection of the null hypothesis. This reduction of statistically significant differences when considering longer term periods further emphasises the point that it is the medium term in which coherences tend to strengthen during bubble regimes.
