Although this test successfully detects single isolated bubbles, Phillips, Shi, and Yu [24] acknowledge it may suffer from reduced discriminatory power when applied to time series with multiple occurrences of bubbles. To overcome this weakness, a further enhancement was proposed, as a new method, called a generalized supremum ADF (GSADF) test. This test allows both the start and end points of data subsets to vary, which in turn enables the identification of multiple bubble regimes in one observed time series. The GSADF test is defined by
But while it’s based on sound, democratic principles, cryptocurrency remains a technological and practical work in progress. For the foreseeable future, nation-states’ near-monopoly on currency production and monetary policy appears secure.

Distributed ledger technology (DLT) is a decentralized database that various network participants administer. Blockchain is a type of DLT where transactions are recorded using a hash, which is an immutable cryptographic signature. This means that if a single block in a chain is modified, it will be immediately clear that the chain has been tampered with. Private and centralized blockchains, on the other hand, exist in which all of the computers that make up the network are owned and operated by a single company.
