Brian Brooks, who had been CEO, resigned recently just months into his tenure amid a slew of compliance setbacks and regulatory scrutiny tied to the crypto exchange’s sister company.

Every cryptocurrency transaction is recorded in a public ledger known as the blockchain, which is the technology that makes it possible for it to exist. This allows people to follow the history of cryptocurrencies like Bitcoin to prevent them from spending coins they don't own, copying transactions, or undoing them. Because blockchain intends to eliminate intermediaries such as banks and internet marketplaces, there are no transaction costs.
It can be seen from Fig 6 that coherence in the short run is erratic throughout the time interval analysed, and that there is little appreciable difference between the bubble and non-bubble regimes. However in the medium term (8–16 and 16–32 days), coherence generally peaks around areas where bubbles have been identified in the price series. The longer term relationship, though, is less dependent on whether the price is in a bubble phase.
