Abstract: Bitcoin is an online communication system that facilitates the use of virtual currency, including electronic payments. This paper aims at analyzing the behavior of Bitcoin returns as a proposal for future currencies while making a comparison between Bitcoin and other conventional currencies. This paper uses quantitative approach to analyze the time series of Bitcoin and that of other conventional currencies during the period 2010–2018. It uses 1) a descriptive statistics for the weekly returns for Bitcoin which includes the mean, standard deviation, maximum value, minimum value, skewness, kurtosis, and Jarque-Bera normal distribution test statistics, and 2) duration dependence test on Bitcoin weekly returns by extracting the weekly returns for the Bitcoin that behave in irregular way of the general Bitcoin return level through autocorrelation regression, and taking the residuals for this regression as a time series for irregular returns.This paper has confirmed no empirical evidence for the existence of a speculative bubble in the Bitcoin values and returns. In addressing the question of whether Bitcoin can act as a reliable substitute for conventional currencies, the returns based analysis shows a huge difference between the behavior of Bitcoin returns from conventional currency returns when comparing both aspects of level and stability. The paper concluded that bitcoin is more an investment than a currency. This paper represents a significant contribution in the path of financial economics and financial risk management, and represents a contribution to the stability of the financial system around the world and mitigating financial crises.

Abstract: This study aims to discuss the main points in the dimensions of the quality of the electronic services to be considered in the future to adapt to future transactions and how to benefit from them. This study relies on the developments and to cope with them so that the banks and customers shift from dealing in the traditional way to the electronic method, which has become a cause of the gap in understanding customers for electronic banking use of the descriptive-analytical approach. A questionnaire was used as a source for collecting data and information about the study variables. It was distributed to three Jordanian banks, and the number of participants was 170. This study uses two primary sources for collecting data and information: secondary sources that relate to the theoretical aspect and preliminary sources related to the analytical aspect of the study subject. The results showed that the impact of e-banking quality dimensions of the study (ease of use, time, confidentiality and security) was high, which required the bank to maintain its high levels and monitor them from time to time. The value of this study comes from the following points: the relationship between the quality of electronic banking services and customer satisfaction this study is one of the few field attempts in Jordan to assess the impact of the quality of electronic banking services on the satisfaction of customers in banks this study provides new scientific results on the impact of the quality of electronic banking services on the satisfaction of customers in the Jordanian banks.

Abstract: The purpose of this research is to investigate the influence of corporate board and audit committee characteristics on firm performance as measured by accounting‐based ratios (earnings per share, return on asset, and return on equity) as well as the market‐based measure (Tobin's Q). In addition, this research introduces political connections to examine whether it can moderate the relationship between corporate board characteristics and firm performance. The study reveals that a higher proportion of independent directors and CEO duality positively affected firm performance. However, board meetings and board financial experience have no affected firm performance. The study also shows that audit committee independence, audit committee size, and audit committee expertise are positively related to firm performance. In contrast, it finds no discernible impact of audit committee meetings on firm performance. Our findings also suggest that the beneficial influences of the corporate board, in terms of higher firm performance, are greater in firms with political connections. To the best of the researchers’ knowledge, this is almost certainly the first analysis to examine the relation between the corporate board, audit committee characteristics, and firm performance, and the moderating effect of political connection of this relationship.
