The present paper seeks to examine the concept of Currency in the Iranian legal system and to explain its conceptual relation to what is today known as cryptoCurrency or Virtual Currency. Understanding this conceptual ratio will be important because if the concept of Currency is to be applied to cryptocurrencies, cryptoCurrency transactions will also be subject to legal provisions relating to unauthorized Currency transactions, such as prohibition of trading without authorization from the central bank. This paper has analyzed analytically and using library resources that none of the elements of the Iranian legislature's definition of Currency include "being money", "being common" and "being foreign". Does not conform to cryptocurrencies. The conceptual relationship of the two is legally a divisive one; Therefore, in the current situation, transfers of what is known as cryptocurrencies will not be subject to Currency transfer laws and prohibitions. The freedom of cryptoCurrency trading and the prohibition of partial Currency trading are undermined by the economic unity of the two.

Background and Aim: Bitcoin (Virtual Currency) is cryptoCurrency that is used only through cyberspace. in the present study, the jurisprudential dimensions of issue have been explained by two approaches of individual and governmental jurisprudence, as well as at two levels of transaction and extraction. In addition, using the research method of multi-stage ijtihad and the opinion of Islamic financial experts and great authorities of imitation, the conditions of the license to use cryptocurrencies have been calculated. Materials and Methods: This research is of theoretical type and the research method is descriptive-analytical and the method of data collection is library and has been done by referring to documents, books and articles. Ethical considerations: In order to organize this research, while observing the authenticity of the texts, honesty and fidelity have been observed. Results: The findings of the present study show that there is disagreement among jurists about the legitimacy of this money. Some jurists consider its illegitimacy and the most important reasons for jurists to reject the legitimacy of Bitcoin is the ambiguity of this Currency, the uncertainty of its origin and destination, its high risk and its foreignness. But some other jurists and economists believe in the legitimacy of Virtual Currency and give reasons for its legitimacy. Conclusion: The view of jurisprudence is affirmative in the face of emerging financial issues such as bitcoin. Money approved by Shiite jurisprudence is not confined to cash. The tax of a Currency has a direct relationship with its desirability among the common sense and the people. In Shiite jurisprudence, there is no evidence that the tax created is a benefit of consumerism, and Virtual Currency and bitcoin are taxed.

The popularity of the concept of crypto-Currency in today's economy has raised many juridical questions. Using an analytical-juridical method, this paper analyzes the activities performed in the process of mining and exchanging of these currencies, with a focus on Bitcoin network. Based on the research findings, juridically, the trading of crypto-Currency is permissible if the general conditions of commercial transactions are met. The crypto-Currency ownership can be justified on the grounds of an effort for decoding and possessing the receiving rewards from the network. Observing the conditions of the contractors, considerations, and the creation of possession through sale by conduct in these currencies is possible. Some objections rose against crypto-Currency trading, including Bitcoin, money laundering, creating a Currency bubble, devaluation of national Currency, obtaining property through illegitimate and illegal means, and the possibility of being deceitful or harmful, cannot be the basis for the illegality of the trade of crypto-Currency. However, using crypto-Currency faces challenges such as consumption of government electricity, partnerships with miners the incapacitated individuals in mining pools. The religious ruler may limit or prohibit the extraction and sale of such goods by issuing a government order, with the adverse effects of Currency development on the market and possible economic, moral and security corruption. Sharia ruler can restrict or prohibit mining crypto-Currency trade in case of negative effects of crypto-Currency in the market, or in case of economic, moral or security problems.

The present study has investigated the contagious of turbulence systemic risk. In this study, the contagious effect of real and Virtual Currency (Bitcoin) fluctuations has been measured. In this regard, the method of self-regression vector analysis (VAR) and the conditional autoregressive model on the heterogeneity of multivariate generalized variances (MGARCH) have been used.The data used in this study, including the exchange rate of the dollar based on the euro and the price of bitcoin in the period 01/2015 and 2020/01, these data were collected and examined and analyzed by regarding the approach of the generalized multivariate conditional variance heterogeneity (CCC) method.The present study is based on the classification of research considering the, nature and direction, respectively descriptive survey, applied and post-event. The results of this study confirm the relationship between the contagins of volatility of real Currency and Virtual Currency. In other words, the main hypothesis of the research based on the contagion of Virtual and real exchange rate fluctuations has been confirmed unilaterally from Virtual exchange rate to real exchange rate.

The foreign exchange market has a very close relationship with other markets and exchange rate changes cause changes in other markets. Contagion means the transfer of fluctuations from one market to another, due to their close relationship. The present study has investigated the contagious risk of turbulence. In this study, the contagious effect of real and Virtual Currency fluctuations has been measured. The data used in this study, including the exchange rate of the dollar based on the euro and the price of bitcoin in the period 01/2015 and 2020/01, were collected and examined by the generalized multivariate conditional variance heterogeneity(MGARCH) and DCC method. The present study is based on the classification of research based on method, nature and direction, respectively descriptive survey, applied and post-event. The results of this study confirm the relationship between the volatility of real Currency and Virtual Currency. In other words, the main hypothesis of the research on the contagion of Virtual and real exchange rate fluctuations has been confirmed unilaterally from Virtual exchange rate to real exchange rate.

Significant fluctuations in the price of cryptocurrencies has led to the identification of effective factors on their prices, and it is important to understand this in the financial markets. In the present paper, the time series analysis method is used to study the determinants of Bitcoin and Ethereum prices. For this purpose, the stock price index on the New York Stock Exchange, the Standard & Poorchr500 Index, the world price of gold and the exchange rate of the dollar and the euro as economic factors, the difficulty of mining, the number of daily transactions, the daily number of circulating Bitcoin and Ethereum as technical factors, The variables of the number of daily tweets related to Bitcoin or Ethereum and the number of daily searches of Bitcoin or Ethereum in Google have been examined as social factors. The time period for Bitcoin is from 2014 to 2020 and for Ethereum from 2016 to 2020. The research method is applied and the statistical population of the research includes two cryptocurrencies, Bitcoin and Ethereum. The econometric method used to study the effect of high factors on the price of Bitcoin and Ethereum in the short-run and long-run periods is OLS and VECM. Among the factors studied, the world price of gold has the greatest impact on the price of Bitcoin and Ethereum. On the other hand, in the short run, the exchange rate of the dollar and the euro and the world price of gold have a negative relationship with the value of cryptocurrencies.

Money is one of the phenomena that are used in the economic life of people for a long time. Despite the simple appearance, this phenomenon is constantly evolving. Since 2009, a new form of money has been created in the world under the title "CryptoCurrency". This exchange facility is out of reach of the banking system and the central bank and is only transmitted through cyberspace. As this kind of money becomes widespread in the economic relations of the world, there is a serious transformation in the nature and functioning of the money. Changes in the nature and function of the economy may have different jurisprudential functions than fiat money. Therefore, it is necessary to accurately identify the jurisprudence system, the nature and economic functions of this phenomenon, and clarify the types of permissible and unlawful rulings in economic relations. In this regard, in this research, at first the cryptoCurrency is introduced and then the jurisprudential aspects of the subject were explained by two approaches of individual and governmental jurisprudence, as well as in two levels of transaction and mining. Finally, using the method of multi-stage ijtihad research and the views of the Islamic finance experts and the authorities, imitating the license terms, the use CryptoCurrency has been counted. Accordingly, one of these types of money, called Bitcoin, is adapted to those circumstances and finally the existence of the doubtful of "La Darar and La Darar" has encountered it with illegal forms.

Deep-sea vessels use various navigational aids like AIS (automatic identification system), ECDIS (electronic chart display and information system), radar, GPS (global positioning system), and etc. vessels use AIS to communicate their navigational characteristics, destinations, and load information. Such data are very helpful for vessel officers; therefore, AIS can be used for communicating the name and position of the vessel as well as navigational signs in the port area. So, this system is very helpful in improving the quality of pilotage as well as improving the safety of navigation in canals like Khur Musa.

National authorities regulating Currency generally do not have direct jurisdiction over Virtual currencies, to date, as they are not national fiat currencies. However, Currency regulators are influencing development of digital Currency in several key indirect ways. Through their authority to protect the value and integrity of national fiat currencies, they take actions affecting digital currencies claiming that such actions are necessary to protect their national Currency. Additionally, as these regulators generally have the authority to control the activities of banks and other key financial institutions, they influence digital Currency development and use by restricting the ability of those institutions to use or accept Virtual Currency. Currency regulators commonly have jurisdiction over conversion of foreign Currency, and through this role, they now routinely restrict the ability of parties to conduct conversions between digital currencies and traditional national currencies. National Currency regulators have also issued substantial warnings to consumers of the risks associated with digital Currency use. Currency regulators often have authority over funds transmission and money transfers, and they frequently exercise that jurisdiction in the context of Virtual Currency use. Some government are now exploring the possibility of government controlled digital Currency and of government participation in the blockchain of existing Virtual Currency platforms.
