HONG KONG/BEIJING (Reuters) -Didi Global is preparing to relaunch its ride-hailing and other apps in China by the end of the year in anticipation that Beijing's cybersecurity investigation into the company will be wrapped up by then, three people directly involved in the relaunch said. The people, who declined to be identified as the information was private, said they expected China's cyberspace regulator to finalise any penalties on the company in December. In July, the powerful Cyberspace Administration of China (CAC) ordered app stores to remove 25 mobile apps operated by Didi - just days after the ride-hailing giant listed in New York.
More importantly, we find that the ACP and ANET factors can price cryptocurrency returns. In particular, all of our five cryptocurrencies have positive and significant exposures to the fundamental factors. The explanatory power of ACP and ANET is over and above any effects related to the Bitcoin and momentum factors. This finding is non-trivial given that the five cryptocurrencies in our sample have consistently accounted for between 80% to 95% of the total cryptocurrency market capitalisation. Furthermore, we extend our factor analysis to an out-of-sample set of 33 cryptocurrencies obtained from the Bittrex exchange. We find that the aggregate computing power and network factors also price cryptocurrencies in this large out-of-sample data set.

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
