Although few cryptocurrencies other than Bitcoin are widely accepted for merchant payments, increasingly active exchanges allow holders to exchange them for Bitcoin or fiat currencies — providing critical liquidity and flexibility. Since the late 2010s, big business and institutional investors have closely watched what they call the “crypto space” too.
While paying for things in cryptocurrencies doesn’t make sense for most people right now, more retailers accepting payments might change that landscape in the future. It’ll likely be much longer before it’ll be a smart financial decision to spend Bitcoin on goods or services, but further institutional adoption could bring about more use-cases for everyday users, and in turn, have an impact on crypto prices. Nothing is guaranteed, but if you buy cryptocurrency as a long-term store of value, the more “real world” uses it has, the more likely demand and value will increase.

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).
