With the popularity of cryptocurrency like bitcoins in recent years, the social circles have been confusing whether cryptocurrency is real money essentially. Lots of voices have clarified the question from the traditional view that regards the nature of money as commodity. However, historical evidences have proved that the traditional theory deviates from the real nature of money originating from debt and is not exactly true. State Theory of Money holds the debt-based opinion on the nature of money and regards the nature of money as the debt of state, which is allowed to be the payment of tax. Therefore based on this, the paper analyzes the debt nature of money and the characteristics of cryptocurrency like bitcoins, and draws the conclusion that cryptocurrency like bitcoins is not accepted by the state as the payment of tax, not the national debt, so not the currency.
This paper attempts to establish that some inherent features of the Bitcoin price can be exploited to produce better forecast results for stock prices. It does so by constructing predictive models for stock prices of G7 countries with symmetric and asymmetric prices of Bitcoin. The underlying statistical properties of Bitcoin prices such as persistence and conditional heteroscedasticity are captured in the estimation process using the Westerlund and Narayan (2015) estimator that allows for such effects in forecasting. There are two striking findings from the analysis. First, the results suggest that accounting for asymmetries is more likely to enhance the predictive power of Bitcoin in forecasting stock prices regardless of the data sample and forecast horizon. Secondly, the Bitcoin-based predictive model for stock prices, particularly the asymmetric variant, outperforms the Fractionally Integrated Autoregressive Moving Average (ARFIMA) model. While there are concerns as to whether the cryptocurrencies are veritable substitutes to the conventional financial assets, their close link with the developed stock exchanges such as those in the G7 countries suggests that they share some common characteristics such as news effects [asymmetries] which can be exploited when forecasting the behaviour of stock prices.

The cryptocurrency market has become increasingly accessible and significant to the financial markets. This is understood by not only major financial firms, governments, and investors, but also the individual market participants globally. We delve into the history of cryptocurrency to begin our examination of the Bitcoin, Ethereum and Litecoin. Understanding the circumstances of their humble beginning, the purpose it served, and the path of their evolution, helps us to create a fuller understanding of its functions, its limitations, and the drivers of its value. This enables us to identify key market factors and variables for deployment within a robust approach for pricing and product offerings associated with Bitcoin, Ethereum and Litecoin. In order to fully capture the volume, variety, and velocity of data associated with these cryptocurrencies, the use of machine learning can provide an advantageous approach to model development for cryptocurrency pricing. This paper provides the development of a promising initial prototype pricing model for Bitcoin, Ethereum and Litecoin. Our proposed pricing models resulted in an average 7% difference between actual and predicted price for Bitcoin and Ethereum, and a 4% difference for Litecoin along a timeline, through the use of machine learning and deep learning, artificial neural networks using the contributing factors of key variables and how they influence and capture pricing and investor behaviour. We also identify theinclusion of additional datasets, such as sentiment market data into the model, along with larger exploration of Blockchain and raw transaction mining to increase the accuracy and forecasting ability of the model.
This article concerns the correlation between criminal law and procedure and the technical, technological and civilisation progress in the form of possibility to stand bail in Bitcoin virtual currency (cryptocurrency) in the criminal procedure. The article, firstly, presents introductory remarks to provide information about the analysed subject. Secondly, there is an outline of the essence and mechanism of applying bail in criminal procedure. Thirdly, the process transformation of money as an element of assets is presented. Fourthly, the article presents a categorisation of digital money and an economic qualification of Bitcoin. The above provides a background for argumentation relating to the legal qualification of Bitcoin as money and presentation of the basic threats connected with this cryptocurrency. The article ends with a brief summary containing the authors’ view on the subject of these reflections and a proposal of the desired legal amendments, addressed to the Polish legislator.
As technology improves and economies become more globalized, the concept of currency has evolved. Bitcoin, a cryptographic digital currency, has been embraced as a secure and convenient type of money. Due to its security and privacy for the user, Bitcoin is a good tool for conducting criminal trades. The Financial Crimes Enforcement Network (FinCEN) has regulations in place to make identification information of Bitcoin purchasers accessible to law enforcement, but enforcing these rules with cash-for-Bitcoin traders is difficult. This study surveyed cash-for-Bitcoin vendors in Oklahoma, Texas, Arkansas, Missouri, Kansas, Colorado, and New Mexico to determine personal demographic information, knowledge of and compliance with FinCEN regulations, and opinions regarding government control of currency and willingness to work with law enforcement among vendors.
A means of exchange and preservation of value is likely as old as our species. Global economic trade is often argued to be as old as trade. The question of the nature of the exchange, of who creates the value and how it is regulated is the issue. While tin from England may have reached Sumeria 4 000 years ago, or Phoenicians' ships entered the Africa area of Cape Palmas at about the same time, the problem of exchange is a central issue. Ideas of money are as diverse as the cultures that produce them, yet today global trade is experiencing modifications of the satisfaction of exchange with new platforms of electronic money. Blockchain technology is touted as foolproof, such claims have appeared in the past with various financial innovations. Such abstractions of value may not be new, but as a product of technology and complexity they create psychological novelty and a form of mesmerizing fetishism (Douglas, M. and Isherwood, B., ed.: The World of Goods: Towards an Anthropology of Consumption. Routledge, London, 1978). Manias of value are also not new, from stock (South Seas Corporation) to tulips (MacKay, C.: Extraordinary Popular Delusions and the Madness of Crowds. Crown Press, London, 1841). The form of the mania is defined and expressed culturally but is often associated with technological change and distance of exchange of partners and clients (Baric, L.: Some aspects of credit, saving and investment in a 'non-monetary' economy (Rossel Island). In: Firth, R. and Yamey, B.S., eds.: Capital, Saving and Credit in Peasant Societies. Aldine Publishing, Chicago, pp.35-52, 1964.). Inequality is also a feature, embedded in economic and technological disruption of trade and exchange. The role of redistribution and taxation are essential in maintaining social credit and equality. We can relate such behaviour to other systems of animal societies.
Cryptocurrencies are private, decentralized currencies that operate via the Internet and have attracted criminals because of the convenience and virtual anonymity they offer. While there are many descriptive accounts of cryptocurrencies and their use both in legal and illegal operations, to date there is no empirical research to understand the use of cryptocurrencies in transnational crime operations, specifically why transnational criminals may find them attractive to either conduct business or to launder their illicit proceeds. Using the environmental criminological framework, this study analyzed 100 cases of cryptocurrency use in transnational crime activities identified through various secondary sources, including online newspaper articles and publicly available court case information. Essentially this study used both quantitative and qualitative analysis to examine the ways in which cryptocurrencies facilitate transnational crimes. The findings indicate that criminals have been using cryptocurrencies to conceal the enormous amounts of money they are receiving for their crimes, specifically money laundering, drug trafficking (illicit drug sales), and terrorism financing. It was found that offenders can conduct business, launder money, and make a profit by using cryptocurrencies to facilitate their crimes, creating for crime opportunities permitted by cryptocurrencies. These opportunities include the ease of floating from one crime to another and using cryptocurrencies to cover offenders’ tracks, where cryptocurrencies can transact, launder, and conceal all in one. It was found that offenders gravitate towards using bitcoin to facilitate their operations, most likely due to its popularity and reliability. When looking at the crime of money laundering and illicit drug sales specifically, it was found that offenders can generate higher operation amounts, spanning into billions of dollars, all while evading detection. With the assumption that transnational criminals are rational beings, money laundering using cryptocurrencies has enormous benefits with these high operation amounts. This coupled with the low chances of being caught by law enforcement, makes money laundering a feasible crime where the benefits far outweigh the risks. This exploratory research is innovative and imperative to expanding academic knowledge on the evolution of crime with the use of cryptocurrencies and assisting in reducing the opportunities cryptocurrencies allow in transnational crime operations.

The aim of the article is to study the theoretical and legal possibilities of using cryptocurrency in purchase and sale contracts, to determine the specificities of such a phenomenon as cryptocurrency (Bitcoin) from the perspective of jurisprudence, and to draw attention of legal scholars primarily to possible further scientific researches on the introduction of this phenomenon in the modern civilian legislation of Ukraine. The subject of the study is the specificities of using cryptocurrency in contracts of purchase and sale. Methodology. The research is based on an analysis of legal acts on the legal regulation of cryptocurrency in Ukraine. By means of the comparative legal method of investigation of certain provisions of Ukrainian legislation, the possibilities and limits of the use of cryptocurrency in contractual relations, in particular, contracts of purchase and sale are determined. The results of the study revealed that the cryptocurrency regime in Ukraine and in many countries is in a legal vacuum. Such a conclusion is based on the lack of clear legal clarification and consolidation of the concept and types of cryptocurrency in the relevant rules of the tax, banking, civil, and commercial law. In case of eliminating this gap, it is advisable to review the state policy on Bitcoin and its analogues. Practical implications. It is necessary and appropriate to introduce a corresponding license for cryptocurrency activities that can minimize the laundering of proceeds from crime or terrorism financing. It is suggested that eventually the relations concerning the digital currency will be regulated in Ukraine, but most likely, it will copy the experience of another state, which may have negative consequences. Relevance/originality. Analysis of a possible use of cryptocurrency in contracts of purchase and sale can become the basis for the development of the most promising directions of domestic civil law in contractual relations.
Compared to gold, cash and commercial bank money, bitcoin is presented as a medium of exchange, functionally similar to electronic money. Bitcoin is known as decentralized, convertible, deflationary and unstable cryptocurrency, deprived of state control and protection. Equally important is the open and global Bitcoin computer network for online transactions, operating without the need for until recently unavoidable intermediaries and different from traditional payment systems. The field of application of virtual currencies is determined by their unusual characteristics, but also by diverse comparative legal regime. Initially as a material for criminal courts and tax authorities, virtual currencies and crypto-subjects are now defined at the EU directives level. Contractual relationships and financial obligations take new forms in crypto-environment, so the question arises: to which extent a positive law is able to absorb until recently improbable concepts. The privacy and freedom that cryptocurrencies bring has its own backwardness, and the legal order is over focused on that side of a coin. On the other hand, the risks in private law transactions involving bitcoins remain unresolved, although legal subjects need this kind of legal protection badly.
Bitcoin is a type of cryptocurrency that implemented decentralized digital currency method. The transaction is monitored and validated by peer-to peer system using hash programming. These transactions are verified by network nodes through the use of cryptography and recorded in a public distributed ledger called a blockchain. The objective of this study is to forecast the Bitcoin exchange rate using weighted moving average method. Data selected in this study are selected hourly from 14 th December 2017 until 18 th December 2017. The forecasting method is using weighted moving average. Then, the validity of the forecasting model is validated using mean absolute percentage error (MAPE) calculation. Results indicated mean absolute percentage error is 0.72%. Therefore, the moving average method is considered as reliable forecasting method for Bitcoin exchange rate. The finding of this study will help investors to make best decision regarding suitable portfolio for their investment.
By using block chain technology, bitcoin has realized a real de centralization and point to point digital currency system, which effectively solved the problems of "double payment" and "curbing inflation". Bitcoin has the value and function of money, therefore, in practical application, we need to consider one problem --"malicious attack", whose success probability affects the basic security performance of the system. This paper is based on the mathematical derivation and analysis of the model and formula given by the "Bitcoin: A peer-to-peer electronic cash system" in the original paper of Satoshi Takemoto's paper. And verify the theoretical guarantee that the success of attack needs the following conditions: Mastering the calculation power of "50%".
