The SADF test finds the largest ADF statistic from all the windows considered. If this value exceeds a critical value, the null hypothesis can be rejected, and it is deemed the series displays explosive behaviour in at least one of the windows (taken as indication of a bubble occurring).
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.

Now that you’ve got an idea of what Safemoon is and its background, we can focus on the coin’s long-term outlook. Most beginner crypto investors simply buy Bitcoin (BTC) or Ethereum (ETH), although lesser-known coins such as Safemoon can be better options if you are looking for quick returns. However, that being said, these options tend to be much riskier, so this will depend on your risk tolerance.
When Ethereum and Bitcoin crashed, these “discount plays” tanked. Now, as the mainstream plays begin to build momentum, these cryptos are struggling to get off the ground and make space for their own identities.
