Predicting altcoin returns using social media.

ABSTRACT: Cryptocurrencies have recently received large media interest. Especially the great fluctuations in price have attracted such attention. Behavioral sciences and related scientific literature provide evidence that there is a close relationship between social media and price fluctuations of cryptocurrencies. This particularly applies to smaller currencies, which can be substantially influenced by references on Twitter. Although these so-called "altcoins" often have smaller trading volumes they sometimes attract large attention on social media. Here, we show that fluctuations in altcoins can be predicted from social media. In order to do this, we collected a dataset containing prices and the social media activity of 181 altcoins in the form of 426,520 tweets over a timeframe of 71 days. The containing public mood was then estimated using sentiment analysis. To predict altcoin returns, we carried out linear regression analyses based on 45 days of data. We showed that short-term returns can be predicted from activity and sentiments on Twitter.

Project description:AimThe research aimed to study the effect of using WeChat (a mobile social media application) on pregastroscopy anxiety and the cooperation of patients with different coping styles.MethodsIn order to decrease patients' pregastroscopy anxiety and improve the tolerance of unsedated gastroscopy, WeChat, a widely used mobile social media application, was applied to provide information prior to their endoscopic procedure. Two hundred and thirty patients who underwent initial unsedated gastroscopy in a large teaching hospital in China were classified into two groups based on their coping style: information seekers or information avoiders, using the Information Subscale of the Krantz Health Opinion Survey (KHOS-I). Each of the two groups was prospectively randomly assigned to either receiving the brochure information or conjunctive interactive WeChat-delivered information of gastroscopy. To measure the level of state anxiety, the State Anxiety Scale of Spielberg's State-Trait Anxiety Inventory questionnaire was used. State anxiety, blood pressure and heart rate were measured at enrollment, upon arrival, and before gastroscopy.ResultsInformation seekers and avoiders who received information from the brochure and the WeChat platform experienced significantly less state anxiety upon arrival and before gastroscopy. Furthermore, information seekers who received information from the conjunctive WeChat platform had lower frequency of retching, lower scores of nausea and bloating, and better tolerance. Information avoiders who received information from the conjunctive WeChat platform had lower frequency of retching, lower scores of discomfort while swallowing the scope and nausea, and better tolerance. However, we found the percentage of information seekers who preferred no WeChat-delivered pregastroscopy information is greater than WeChat-delivered information at the initial questionnaire. No significant difference was found in blood pressure or heart rate upon arrival and before gastroscopy.ConclusionsAlthough people preferred no WeChat-delivered pregastroscopy information, the provision of gastroscopy information through a mobile social media application, such as WeChat, could significantly reduce patients' pregastroscopy anxiety, lower the frequency of retching, reduce the scores of nausea and bloating, and improve tolerance for information seekers. In addition, it could lower the frequency of retching, reduce the scores of discomfort while swallowing the scope and its concurrent nausea, and improve tolerance for information avoiders.
