В частности, исследуется, влияет ли индекс читабельности текста новостей на волатильность биткоина. Несмотря на то что чрезмерная волатильность угрожает биткоину не стать успешной валютой, многие ученые заинтересованы в детерминантах такой волатильности. Такие факторы, как спекулятивные инвестиции или внимание общества, являются драйверами изменчивости курса биткоина. В связи с этим вопрос исследования влияния новостей на курс биткоина является актуальным. Цель данной работы состоит в том, чтобы оценить влияние эмоциональной тональности новостей о биткойне на его курс. Эмпирическая база исследования довольно объемная, поскольку включает в себя более 1330 новостей из информационной базы Thomson Reuters за период с 19.08.2011 по 16.08.2016 г. по рынку биткоина. Методология исследования включает анализ тональности, проведенный с использованием словаря МакДональда и Лоугрэна, также проведен анализ взаимозависимости временных рядов на основе каузального анализа с применением теста Грэнджера на причинность.В статье поставлены три гипотезы о влиянии новостей на курс биткоина. В ходе исследования получили подтверждение две из них. Доказана первая гипотеза о более значительном влиянии негативных новостей, чем позитивных с учетом пяти лагов. Вторая гипотеза о влиянии положительной тональности в новостях на курс в результате применения теста Грэнджера на причинность не подтвердилась, поскольку положительные значения данного теста были получены в двух лагах из пяти. Также была доказана третья гипотеза о том, что высокий индекс читабельности оказывает влияние на волатильность биткоина за весь изученный период с учетом всех пяти лагов. Таким образом, предположение о влиянии эмоционального освещения новостей на курс биткоина подтвердилось.</p></abstract><trans-abstract xml:lang="en"><p>The authors assess the impact of the emotional tonality of bitcoin news on its exchange rate. In particular, we studied the hypothesis of the impact of the readability index of the news text on the volatility of bitcoin. Despite the fact that excessive volatility threatens bitcoin not to become a successful currency, many scientists are interested in the determinants of such volatility. Factors such as speculative investments or the attention of the society are the drivers of the volatility of the exchange rate of bitcoin. In this regard, the question of studying the impact of news on the bitcoin exchange rate is relevant. The purpose of this paper is to assess the impact of the emotional tonality of bitcoin news on its exchange rate. The empirical base of the study was quite extensive since it includes more than 1330 news from the Thomson Reuters information base for the period from 19.08.2011 to 16.08.2016 on the bitcoin market. The research methodology includes the sentiment analysis conducted by using the dictionary MacDonald and Loughran and also the analysis of the interdependence of time series-based causal analysis using the test of Granger causation. We present three hypotheses about the impact of news on the bitcoin exchange rate. During the study, two of them were confirmed. We proved the first hypothesis that the negative news had a more significant impact than positive ones, taking into account the five time-lags. The second hypothesis about the impact of positive tonality in the news on the bitcoin exchange rate, using the Granger test for causation, was not confirmed, since the positive values of this test were obtained in two time-lags out of five. We can confirm that the third hypothesis was proved — the high readability index has an impact on the bitcoin volatility for the entire studied period, taking into account all five time-lags. Thus, the assumption about the impact of the emotional tonality of news on the bitcoin exchange rate can be confirmed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>биткоин</kwd><kwd>криптовалюта</kwd><kwd>текстовый анализ</kwd><kwd>новости</kwd><kwd>анализ тональности новостей</kwd><kwd>цифровая валюта</kwd><kwd>влияние новостей</kwd><kwd>волатильность биткоина</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bitcoin</kwd><kwd>cryptocurrency</kwd><kwd>text analysis</kwd><kwd>news</kwd><kwd>sentiment analysis of news</kwd><kwd>digital money</kwd><kwd>news impact</kwd><kwd>bitcoin volatility</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Nakamoto S.
