Cryptocurrencies and the issues of financial and economic stability

Elżbieta Mirecka

Cel – Celem opracowania było przedstawienie w aspekcie poznawczym różnych opinii odnośnie do istoty kryptowalut, jako nowego elektronicznego instrumentu płatniczego i jego wpływu na bezpieczeństwo ekonomiczne gospodarki zarówno światowej, jak i lokalnych. Metodologia badania – Analiza opinii finansowych i gospodarczych, analiza źródeł prawa, prezentacja danych statystycznych dotycząca wartości kryptowalut, szacowanie wpływu kryptowalut na poziom gospodarki wybranych państw na podstawie statystycznych danych gospodarczych. Wynik – Opinie na temat istoty kryptowalut i ich oddziaływania są skrajnie zróżnicowane. Kategoria ta, ze względu na jeszcze krótki okres funkcjonowania i odmienność w stosunku do tradycyjnych instrumentów finansowych, nie doczekała się jeszcze pełnej definicji prawnej. W obszarze funkcjonowania banków centralnych zauważa się skrajne stanowiska – od zakazu wprowadzania kryptowalut na rynki finansowe, aż do chęci ich emisji. Także w ocenach ich wpływu na poziom gospodarczy krajów zauważa się odmienne stanowiska: od negacji ich wpływu, a nawet zagrożeń, aż do nadawania kryptowalutom rangi czynnika wzrostu gospodarczego. Oryginalność/wartość – Opracowanie wybiegające poza klasyczne ukazanie mechanizmu funkcjonowania kryptowalut, a w szczególności jako czynnik spekulacyjny przy decyzjach finansowych indywidualnych inwestorów. Wyniki sugerują brak jednolitego stanowiska i opinii zarówno badaczy problemu, jak i państw i instytucji gospodarczych, finansowych i nadzorujących. Brak także wypracowanych mechanizmów ochronnych przed negatywnym wpływem kryptowalut na bezpieczeństwo ekonomiczne gospodarek.

CHARAKTER PRAWNY BITCOIN

Justyna Dąbrowska

Artykul podejmuje probe oceny charakteru prawnego kryptowalut. Bitcoin i inne waluty wirtualne są przedmiotem powszechnego obrotu. Z uwagi na niemoznośc zakwalifikowania bitcoin jako pieniądza, środka platniczego ani instrumentu finansowego, obrot ten ma charakter nieuregulowany. Tymczasem, choc bitcoin niewątpliwie wykazuje wiele zalet, stwarza dla uzytkownikow sieci zagrozenie związane z niestabilności tej ‘waluty’, anonimowością transakcji, ktora sprzyja niewywiązywaniu sie z kontraktow i zjawisku tzw. prania brudnych pieniedzy oraz moze powodowac ryzyko utraty lokowanych środkow w wyniku bankructwa czy zamkniecia organizatora platformy transakcyjnej.

BARRIERS TO THE FUNCTIONING OF THE BITCOIN SYSTEM – USER ASSESSMENT

Anna Piotrowska, Dariusz Piotrowski

Bitcoin is a system created to service micro-payments in e-commerce, as well as the digital unit of value functioning in the system's environment. When analysed, the behaviour of market participants indicates that the introduction of investment applications of the cryptocurrency, in parallel with its original payment application, had a tremendous impact on the larger-scale functioning of the system. This was aided by the functioning of many trading platforms allowing for exchange into traditional currencies and a high volatility of quotations. Without doubt, bitcoin may be branded a ground-breaking financial innovation or a work of genius. However, the growing, and even global use of bitcoin has brought some of the system's imperfections to light. As the system developed, bitcoin users started to have a better view of the threats to the correct functioning of the system arising from its construction. The paper aims to indicate the main barriers limiting the functioning of the bitcoin system, and its use in payments in particular. The work has adopted the following research hypothesis: In the early stages of bitcoin functioning, users had little awareness of the technological flaws of the system. The study analyses the literature on the subject and the results of a survey carried out among Polish bitcoin users. The analysis confirms of the research hypothesis, as it shows that in the system's first several years, users identified the following threats to the system's functioning: the speculative nature of bitcoin, the lack of adequate awareness in society which would allow for a widespread use of the innovation, potential too strict regulation of the cryptocurrencies market or its banning. The authors also present threats to the functioning of the system which in their opinion are of greatest importance at the moment. These relate to the existence of intermediaries, the lack of systemic incentives addressed to bitcoin merchants, growing costs and payment processing time. The authors intend to indicate those aspects of bitcoin's functioning in order to make the use of cryptocurrencies more conscious and contribute to limiting financial risk of system users.

Aspectos inovativos do bitcoin, Microestrutura de mercado e volatilidade de Preços.

Thiago Pinto de Carvalho

A presente dissertacao realizou uma analise sobre aspectos conceituais, inovativos, mercadologicos e quantitativos do Bitcoin. Apos expostos conceitos basilares sobre o Bitcoin, moedas digitais e moeda buscou-se contextualizar o Bitcoin como inovacao financeira. Com relacao aos aspectos inovativos o surgimento do Bitcoin representou uma inovacao radical e pre-paradigmatica com potencial de destruicao criativa. Tambem foram expostos os conceitos mais modernos da teoria da inovacao e percebeu-se que o Bitcoin apresenta caracteristicas de Inovacao Disruptiva (ID) de dois tipos: Low and (ID) e New Market (ID). Quanto aos aspectos mercadologicos e estruturais foi investigada a existencia de semelhancas entre o mercado de credito e debito do Bitcoin e a estrutura tradicional do mercado de cartoes conhecida por Mercado de Dois Lados (M2L). Verificou-se a perfeita adequacao do Bitcoin a estrutura M2L, mas apenas no mercado de cartoes de debito. O sistema de credito existente no mercado do Bitcoin nao se conforma da maneira tradicional. Buscou-se tambem compreender os determinantes da volatilidade dos precos do Bitcoin. Para atingir este objetivo foram realizados dois tipos de analises: univariadas e multivariadas. Para estimar a volatilidade univariada foram estimados os modelos ARCH, GARCH, EGARCH e TARCH cujos resultados apontaram existencia de volatilidade persistente. Ja analise quantitativa multivariada apresentou o objetivo de compreender a interacao das volatilidades entre o Bitcoin e outras variaveis financeiras. Foi aplicada a metodologia DCC M-GARCH que possibilita a obtencao dos parâmetros por meio das quasicorrelacoes da volatilidade. Os resultados apontaram a existencia dos efeitos ARCH e GARCH em todos os casos. Embora as variaveis explicativas nao apontem significância a analise multivariada da subamostra aparentemente realiza movimento de convergencia. Em todos os casos foram considerados os retornos das series. Todos os modelos foram estimados para a amostra considerando o periodo de 13 de Setembro de 2011 e 23 de Junho de 2015 e para uma subamostra que abrange o periodo a partir de 10 de Marco de 2013.

ANONYMITY OF BITCOIN AS A SECURITY THREAT

Leszek LISIECKI, Kamil KUCHARSKI

Proces globalizacji i rewolucji informacyjnej to zjawiska, które determinują rzeczywistość społeczno-gospodarczą współczesnego świata. Znalazły one praktyczne odzwierciedlenie w funkcjonowaniu systemów pieniężnych w globalnej gospodarce światowej, przede wszystkim w nowej postaci cyberwaluty, jaką jest bitcoin. Przedmiotem artykułu są przesłanki powstania, istota, zasady i sposób działania bitcoina. Jego cechy oraz coraz szerszy zakres funkcjonowania tej cyberwaluty mogą w przyszłości zagrażać bezpieczeństwu w wymiarze społecznym, gospodarczym i międzynarodowym.

Bitcoin - Nowa Wirtualna Globalna Waluta?

Elżbieta Chrabonszczewska

Abstract The aim of the paper is to present the phenomenon of the new virtual currency bitcoin, and analyse its economic significance. The paper examines the origin, notion, functions and mechanism of emission of the BTC. The theoretical aspects of creation of the BTC and its advantages and weakness are also explained. The results of the analysis show that bitcoin does not eliminate current problems of traditional currency but also generates new risks for its users. The risks could as well affect the central banks (the legal risk, the risk to payment system stability, and the reputation risk). Three contributions of this paper to the problem of the BTC are worth distinguishing. Firstly, the scientific literature lacks information and data about the BTC - the main source of information is the Internet which reliability cannot be fully guaranteed. Secondly, periodical examination of development of the risk connected with the BTC is necessary. Thirdly, it is a basis to begin discussion on the new virtual currency which bitcoin is.

Bitcoin a definicja i funkcje pieniądza

Anna Piotrowska

The appearance of bitcoin is the beginning of a new era in which advanced technological capabili- ties have changed the perspective on the financial system's functioning rules and have expanded the understanding of the category of money. Bitcoin is used in commercial transactions, transfers and as an investment asset. The establishment of bitcoin is a part of the movement away from cash transactions and the general acceptance of non-material form of money observed around the world. The aim of the study is to analyse the bitcoin cryptocurrency in the scope of the fulfilment of the definition criteria and functions of money formulated in an economic theory, and to present the current legal situation in selected countries relating with its functioning.

It Will Cost You Nothing to 'Kill' a Proof-of-Stake Crypto-Currency

Nicolas Houy

It is a widely spread belief that crypto-currencies implementing a proof of stake transaction validation system are less vulnerable to a 51% attack than crypto-currencies implementing a proof of work transaction validation system. In this article, we show that it is not the case and that, in fact, if the attacker's motivation is large enough (and this is common knowledge), he will succeed in his attack at no cost.
