Résumé :

Market traders often buy and sell volatile assets to maximize total returns. We have developed an optimal trading strategy model using gold and bitcion daily price streams to meet this need. Based on a sliding window, we use the ARIMA model to predict the daily prices of gold and bitcoin, respectively. Meanwhile, the Granger causality test results showed that they were not cointegrated in the short term. We construct a multi-objective dynamic trading sub-model that considers maximum investment value, minimum trading frequency, and minimum trading risk factors based on historical and forecast sequences. Finally, we validate the optimal trading strategy model using the efficient frontier and conclude that the model is accurate.

Résumé :

It is unclear how bitcoins should be qualified from a legal perspective. This qualification is, among other things, relevant to determine how bitcoins should be transferred, pledged, attached and executed. In this article, bitcoins and bitcoin transfers are explained from a technical perspective and subsequently qualified from a contract and property law perspective. Given the borderless nature of bitcoins and its underlying bitcoin technology, these subjects are dealt with in an international manner, often drawing upon legal concepts which form the backbone of most if not all legal systems, especially those in the EU. In this article, the following conclusions are reached. First of all, from a contract law perspective, the bitcoin network qualifies as a multi-party contract to which the various participants (users, miners and nodes) accede by participating in the network for the first time and, in doing so, accept the third-party rights clause stipulated in that agreement in their favour. Secondly, from a property law perspective, the rights with respect to the bitcoins credited to a bitcoin address are put to bearer at the same moment these bitcoins are so credited. They are put to the bearer of the value bearer on which the private key associated with that bitcoin address is stored. That value bearer embodies the right of that bearer to perform the work necessary to transfer the bitcoins on that bitcoin address, more specifically vis-à-vis the miners to validate that transaction and vis-à-vis the nodes to verify the work of the winning miner. Those bitcoin rights can be transferred, pledged, attached and executed by possession of the value bearer.

Çalışmanın temel amacı bitcoin ile BIST30 vadeli, altın vadeli ve döviz vadeli işlemler piyasası arasındaki volatilite etkileşimini araştırmaktır. Bu doğrultuda 25.07.2010 – 13.02.2022 dönemine ait haftalık veriler kullanılmıştır. Bitcoin ile BIST30 vadeli, altın vadeli ve döviz vadeli işlemler piyasası arasındaki volatilite etkileşimini araştırmak için çok değişkenli GARCH modellerinden DCC-GARCH modeli kullanılmıştır. Bitcoin, BIST30 vadeli, altın vadeli ve döviz vadeli işlemler piyasasında meydana gelen volatilitenin kalıcı olduğu tespit edilmiştir. Bitcoin ile BIST30 vadeli işlemler piyasası arasında çift yönlü, altın ve döviz vadeli işlemler piyasasında bitcoin’e doğru tek yönlü volatilite etkileşimi bulunmaktadır. Bitcoin ve BIST30 vadeli işlemler piyasası, altın vadeli işlemler piyasasından bitcoine doğru negatif yönlü etkileşim mevcuttur. Fakat döviz vadeli işlemler piyasasından bitcoine doğru volatilite etkileşimi ise pozitif yönde olduğu saptanmıştır.

Résumé :

Abstract: The silence of the RBI on the regulatory status of bitcoins may prove to be damaging. An industry has grown around bitcoins in India- traders, exchanges and merchants who accept payments in bitcoins. Bitcoins have already gained wide acceptance around the world- hence banning them would not be an option in India. Instead, this industry would need to be regulated. The sooner this is done, the better. A bitcoin is a virtual currency first introduced in the year 2008 by an anonymous group called Satoshi Nakamoto. It’s an open source peer-to-peer cryptographical system (direct connections without an intermediary) where transactions happen through a public ledger called blockchain, handling users’ data anonymously. Eight years since its introduction, bitcoin is today the most widely used and accepted digital currency.By categorically reiterating that cryptocurrencies could not be part of the ‘payment process’, India buries the economic possibilities of crypto as a currency. However, the positive focus on blockchain technology is redeeming the bitcoin

Résumé :

Day by day the numbers of Bitcoins owners are increasing and as the time lapses, they also will face the death. In Perlis, Bitcoins is recognised as a wealth (mal) and subject to zakat by State Fatwa Committee of Perlis. Hence, this paper aims to discover the inheritability of bitcoin according to Shariah in Perlis. As a result, this study employed a qualitative research approach by interview in order to discover the inheritability of bitcoin as a mal according to Shariah. Purposive sampling was used in the study. The finding of this study indicated that the existing fatwa on bitcoin is silent on the inheritance ruling of bitcoin. The researcher urged that this inheritance ruling must be tabled and gazetted by the state fatwa committee of Perlis in order to ensure the continuity of bitcoin to the next generation. Therefore, this study has contributed in comprehensive Shariah views behind the permissibility of Bitcoin in Perlis and provides some important policy implication for the regulator and state fatwa committee of Perlis to fulfil the lacuna in the fatwa related to bitcoin.

Résumé :

Bitcoin, a decentralized digital currency, has received a lot of interest due to its potential to challenge the traditional financial system. This study applies a coefficient of variation analysis with an emphasis on the idea of dividing the entire supply by 21 million to determine the degree of decentralization for Bitcoin. The coefficient of variation is a statistical indicator of diffusion, making it possible to analyze how many Bitcoins different stakeholders hold. We can learn more about the degree of wealth concentration or distribution among Bitcoin users by examining the degree of decentralization using this method. This research calculates the coefficient of variation using publicly available information on Bitcoin addresses and the holdings linked to those addresses. The findings will contribute to the ongoing discourse on Bitcoin's decentralization and shed light on the potential impact of the fixed supply of 21 million Bitcoins on wealth distribution within the Bitcoin network.

Résumé :

Recent years have witnessed the advances of e-money systems such as Bitcoin, PayPal and various forms of stored-value cards. This paper adopts a mechanism design approach to identify some essential features of different payment systems that implement and improve the constrained optimal resource allocation in Germany. Bitcoin is a digital, decentralized, partially anonymous currency, not backed by German or any government or other legal entity, and not redeemable for gold or other commodities. Bitcoin relies on peer-to-peer networking and cryptography to maintain its integrity. Compared to most currencies or online payment services, such as PayPal, bitcoins are highly liquid, have low transaction costs, and can be used to make micropayments in Germany. Although the Bitcoin economy is flourishing, Bitcoin users are anxious about Bitcoin’s legal status. This paper examines a few relevant legal issues. The research question is to investigate how supplementary digital terminating currency Bitcoin can provide a superior fallback position as e-gold standard in Germany and worldwide. Digital self-liquidating e-Gold ounce could be distributed immediately to voters by using swipe cards used by some governments for transit facilities. Bitcoins as e-Gold ounce do not provide a viable medium of exchange because of the cost of their purchase, creation and/or exchange.

Résumé :

The presence of bitcoin invites many uncertainties, such as concerning its legality and the statement that bitcoin is not an official currency in Indonesia. Objective: This research aims to analyze the bitcoins in the perspective of the Islamic Law. Method: This research uses the literature review method. The literary materials obtained are in the form of scientific papers, online media, books, etc. that concerns the analyzed object. Findings: The circulation of bitcoin in Indonesia as a medium of exchange cannot be regarded as a currency, as it does not fulfill the terms and conditions for something to be called money. The bitcoin’s function does not commensurate with the function of money in the concept of the Islamic economy, as it tends to be a traded commodity rather than a facility of transactional exchange. In the perspective of Islamic law, the speculative use of bitcoins may bring one to the risk of violating the law on gharar (uncertainty, hazard); dharar (a transaction that may bring loss to a party); and qimar (game of chance). No authority guarantees bitcoins, and this causes harm. In conclusion, bitcoins produce more harm than good. Thus, its usage is prohibited by Islamic law. Function: This research provides an explanation of the legality of bitcoins, that may aid the Indonesian society to decide whether or not they can use bitcoins according to the law and th sharia. Novelty: There has not been any researches that study the same topic as that discussed in this article.

Résumé :

Since the formation of Bitcoin in 2009, various private digital currencies have been presented. Bitcoin is by a long shot the best one. It has been getting a great deal of media consideration, and its all out market worth has arrived at 20 billions USD in March 2017. More importantly, a number of central banks started recently to explore the adoption of cryptocurrency and blockchain technologies for retail and large-value payments. Bitcoin is a digital currency based on a peer-topeer payment system managed by an open source software and characterized by lower transaction costs, greater security and scalability than fiat money and no need of a central bank. In spite of criticisms about illegal uses and social consequences, it is attracting the interest of the scientific as well as economic community. Be that as it may, notwithstanding Bitcoin’s worth, the paper clarified, physical stores have been delayed to acknowledge it as a technique for installment. Subsequently, a few lookers are getting to be critical about whether this tech-trendy person digital money, which everybody has known about however the vast majority don’t genuinely comprehend, will ever supplant conventional cash. Only one exchange can use as much vitality as a whole family unit does in seven days, and there are around 300,000 exchanges each day. That vitality request is usually met through petroleum product vitality sources, which, alongside contaminating air and water, radiate ozone harming substances that reason environmental change. At the end of the day, Bitcoins are adding to the warming of the climate without giving a noteworthy open advantage consequently. Some Bitcoin lovers guarantee that it will in the long run become a standard money, and that the cryptogovernance framework whereupon it’s manufactured could really support the earth. In any case, the Bitcoin market is unstable, its future dinky. Off-the-rack PCs used to be incredible enough to mine Bitcoins. Presently, on the grounds that the math issues are so perplexing, they should utilize particular equipment called Application Specific Integrated Circuit, or ASIC. These mining machines are huge and run hot, and the individuals who use them—either Bitcoin mining organizations or Bitcoin devotees cooperating—utilize a great deal of power to do as such. Organizations and associations that mine bitcoin will once in a while have a huge number of these machines pressed into far reaching distribution centers. Hence, the present study is an attempt to define and evaluate the current trends of the literature concerned with the sustainability of bitcoin, considering the environmental impacts and economic aspects. The study is divided into four parts – first part explains the concept of bitcoin in detail with its history. The second part of the study details the statement of the problem. The third part deals with results and discussions and the last is the concluding part. In the results and discussion part, the data dealing with trends in the value of bitcoin in USD and in Indian markets are exhibited. The main exchanges dealing with bitcoin in India are then given and the number of bitcoins available and their market capitalisation worldwide is shown. From the analysis, it is very clear that the value of bitcoin has tremendously increased over the period of time. One of the main allegations against the bitcoin trading is its fluctuating volatility depicted. It’s because of this issue, that bitcoins are considered to be very dangerous commodity to be traded. Also, form the point of sustainability, it emerges that the transition of the whole monetary system in the new cryptocurrency will result in an unacceptable amount of energy consumed to mine new bitcoins and to maintain the entire virtual monetary system, and probably bitcoin will remain a niche currency.

Résumé :

Bitcoin is a decentralized digital currency, which is not controlled by a single authority or government. Bitcoin uses blockchain technology to verify transactions and guarantee user security and privacy. The fluctuating value of bitcoin is influenced by opinions that develop because many people use these opinions as a basis for buying or selling bitcoins. Knowledge to find out the market conditions of bitcoin based on public opinion is very necessary. This study aims to develop a hybrid model for bitcoin sentiment analysis. The dataset used came from comments on the Indodax website chat room, as many as 2890 data were successfully collected, then do data preprocessing, translate to english, text labeling and used hybrid parallel CNN and LSTM using word embedding glove 100 dimensions. Results of the experiments conducted, at 90:10 data splitting and 100 epochs is the best model with 88% accuracy, 86% precision, 78% recall and 81% f1-score, while the classification of opinion text comments on indodax chat results in 64.22% neutral comments, 21.14% positive comments and 14.63% negative comments. Based on research results, use of a parallel hybrid model provides a high accuracy value in classifying text, from these results positive comments are more than negative so that investors are advised to buy bitcoins.

Résumé :

With the rapid development of information and information technology, many activities in our daily life can be integrated online, making it easier and more efficient. The significant increase in the number of online users has led to the concept of visual terms and the creation of a new business entity called cryptocurrency, making it easier to conduct financial transactions such as buying, selling and trading. Cryptocurrency is a valuable and invisible electronic tool for a wide variety of applications and networks, including online social networks, online social games, virtual worlds and peer-to-peer networks. In recent years, obvious costs have spread to various programs. This paper examines the expectations of cryptocurrency users for the future. It examines users' reliance on cryptocurrency when virtual currency is fully controlled and out of control. Furthermore, the paper seeks to determine the prevalence of cryptocurrency use to provide a clear picture with an active perspective. The magazine also examines how 21 different countries have reacted to cryptocurrency in terms of policies and regulations to create a clearer picture of its impact on the regulation of various laws in India.

Résumé :

Många länder går mot ett samhälle där kontanter används till en mindre grad vilket har lett till en ökning av elektroniska betalningsmetoder. Utöver kortbetalningsmetoder har andra mer hög teknologiska betalningsmetoder vuxit fram. Bland dem är Bitcoin ett nytt system som vuxit sig relativt stor under de senaste åren. Bitcoin är både kritiserat och hyllat i olika medier. Utifrån de två väletablerade teorierna; Diffusion av innovation och Teknologi acceptans modellen avser studien att identifiera betydande faktorer i Svenska företags adaption av Bitcoin. Denna kvalitativa studie bygger på strukturerade telefon- och mailintervjuer i samband med samling av sekundärdata vilket tillsammans skapar empirins underlag. Studien består av åtta telefonintervjuer och tre mailsvar Studien är av deduktiv natur då den undersöker innovationen utifrån redan befintliga teorier. I användandet av teorin återfinns ingen undersökning av innovationen, istället har innovationer av närliggande karaktär studerats för stödjande av faktorernas vikt för adaptionen av innovationen. Resultaten visar att relativa fördela, kompatibilitet, svårighet att använda och uppfattad risk bör vara de främsta faktorerna. Utöver dessa faktorer finns bevis som pekar på att sociala influenser och tekniskt intresse även är viktiga för Bitcoins adaption.

Résumé :

El presente trabajo de investigación funda su importancia en el análisis de la utilidad y facilidades que permite una nueva moneda digital. Dicha moneda se encuentra en etapa de auge, ya que cada día cuenta con más usuarios o poseedores de la misma; esto conforma una amplia red que va creciendo día a día. La amplitud de dicha red genera que la moneda sea cada día más aceptada y que una alternativa de pago respecto al papel moneda. Cabe mencionar que dicha moneda no sólo posee características que la hacen utilizable desde el punto de vista de las transacciones, sino que toma un segundo plano frente a su utilidad para todo tipo de inversiones la cual aumenta su significatividad constantemente. Principales conceptos teóricos: Bitcoin es la más reciente tecnología digital que viene a ser presentada como una moneda. Es un invento que viene a aprovechar las posibilidades que existen en la era digital para solucionar distintos inconvenientes de la humanidad, como son el transporte de valor económico en el tiempo y en el espacio. La moneda, para ser considerada como tal, debe poseer las siguientes funciones: • MEDIDA DE VALOR. Ya que el valor de las cosas puede ser representado por medio de las unidades que ella representa. • INSTRUMENTO DE ADQUISICIÓN DIRECTA. Puesto que permite adquirir cualquier bien en función de su valor. • INSTRUMENTO DE LIBERACIÓN DE DEUDAS. Debido a que tiene una fuerza cancelatoria de las mismas al constituirse en un medio de pago reconocido legalmente. • MEDIO DE ATESORAMIENTO DE RIQUEZA. Se puede atesorar para necesidades futuras debido a que conserva indefinidamente su valor. Para ser considerado medio de pago, un instrumento debe poseer las siguientes características: • El gran valor que representa con relación a su peso y volumen. • Reconocimiento unánime como medio de pago, que impide juzgar acerca de su calidad. • Su divisibilidad, que permite fraccionar su valor en forma ilimitada. • La dificultad en su falsificación, que impide la circulación de un medio de pago que no se encuentra debidamente controlado, ya que en cada país se aprueba sólo una moneda a la vez. Metodología: Se tuvo en cuenta un enfoque cuantitativo, en donde se plantea un problema de estudio delimitado y concreto. Se revisó la literatura y se constituyó un marco teórico, elaborando la hipótesis y sometiéndola a prueba.

Résumé :

Forskningsfråga: Vilka faktorer har drivit intresset för handeln av bitcoin det senaste året och vad kan förklara dem? Syfte: Syftet med den här studien är att få en ökad förståelse för varför bitcoin har blivit extra uppmärksammat det senaste året samt att undersöka vilka faktorer det ökade intresset beror på. Studien syftar även till att bekräfta eller förkasta de hypoteser som tar form i de valda teorierna. Metod: En kvalitativ och kvantitativ studie med en abduktiv ansats där empirin samlades in via enkäter och två intervjuer med experter inom ämnet. Slutsats: Studiens slutsats visar att intresset för handeln med bitcoin till en viss del styrs av hur kryptovalutan framställs i media och andra sociala sammanhang. Utöver att flockbeteendet spelar roll är egenskaperna bitcoin besitter också avgörande. Flertalet anser att kryptovalutan är värdig att investera för att den är decentraliserad, den ses som ett inflationsskydd och den ger en hög avkastning.
Research question: Which factors have driven the interest in bitcoin the last year, and what can explain this? Purpose: The purpose of this study is to get a better understanding of why Bitcoin has received increased attention the past year and to explore which factors have had an impact on the increased interest. The study also aims to confirm or reject the hypotheses which can be found in the theory chapter. Method: A qualitative and quantitative study with an abductive approach where the empirical data was collected through a survey and through two interviews with bitcoin experts. Conclusion: The study concludes that the increased interest in bitcoin trading partially depends on how it is portrayed by media and by other social participants. In addition to the fact that sheep-like behavior is an important factor, the quality bitcoin possesses is also crucial. The majority of our respondents believe that the cryptocurrency is a worthy investment because of its qualities such as decentralization, protection against inflation and a high return.

Résumé :

Tässä tutkimuksessa käsitellään, kuinka bitcoin-verkko toimii ja mitä eri käyttötarkoituksia sillä on. Tutkimus rajattiin bitcoiniin, koska se on ensimmäinen ja eniten käytetty kryptovaluutta. Tutkimus perustui kirjallisuustutkimukseen. Tietotekniikan kehittyminen on vaikuttamassa myöskin maksuliikenteeseen. Transaktioita on suoritettu jo verkon kautta esimerkiksi pankkien toimesta ja kolmansien osapuolien tarjoamien palvelujen avulla. Kryptovaluutat ovat täysin uusi ilmiö maksutapahtumien näkökulmasta. Kryptovaluutat pyrkivät olemaan täysin omia valuuttojansa ja toimimaan ilman keskuspankkia. Kryptovaluutat toimivat täysin verkossa eikä ne ole fyysisesti käsin kosketeltavissa. Toinen suuri ero traditionaalisiin pankkivaluutoihin on se, että kryptovaluutoilla ei ole omaa keskuspankkia. Kryptovaluuttojen tapauksessa kaikki transaktiot on julkista tietoa, mitä ei tapahdu traditionaalisissa pankkivaluutoissa. Käytännössä kaikki kryptovaluutoilla suoritetut transaktiot näkyvät julkisina. Käyttäjien identiteetti suojataan niin, että henkilötietoja ei tallenneta järjestelmään. Tämä on ennenkuulumatonta traditionaalisessa pankkimallissa, sillä henkilötiedoilla rajoitetaan varoihin pääsyä esimerkiksi verkkopankissa tai pankin asiakaspalvelupisteellä asioidessa. Generoiduilla kryptovaluutoilla ei näin ollen ole ollenkaan omistajia. Käyttäjillä on olemassa julkisia avaimia, joihin voidaan vastaanottaa varoja, sekä yksityisiä avaimia, joilla varat ovat käytettävissä. Transaktiot vahvistetaan erillisen louhijaverkon avulla. Louhijaverkon solmuksi voi liittyä kuka tahansa. Transaktioiden vahvistuksesta louhijat saavat palkkioksi generoitua kryptovaluuttaa, ja tällöin valuuttaa saadaan luotua lisää.

Résumé :

Denna uppsats har två delsyften. Det första delsyftet är att ge en beskrivning av vad bitcoin är och hur tekniken bakom bitcoin fungerar. Det andra delsyftet är att redogöra för hur bitcoin ska värderas. Genom en selektiv litteraturöversikt med avseende på värderingsmodeller för bitcoin har det andra delsyftet besvarats. I litteraturen har tre olika ansatser till att värdera bitcoin återfunnits och denna uppsats presenterar respektive värderingsansats för bitcoin och de resultat som har framkommit av tidigare studiers empiriska test. I den första modellen har bitcoin klassificerats och värderats som ett betalningsmedel. Ansatsen för den andra modellen är att värdera bitcoin som en finansiell tillgång. Utgångspunkten för den tredje modellen är att bitcoin är ett nätverk och ska värderas utifrån den aspekten med hjälp av Metcalfe’s lag. Sammanfattningsvis kan alla tre modeller förklara bitcoins prisbildning till en viss del. Slutsatsen är att bitcoin i högre grad kan klassificeras och värderas som en finansiell tillgång, eller som ett nätverk, än som ett fungerande betalningsmedel.

Résumé :

Purpose – to investigate the possible influence of bitcoins and the Blockchain on exchange rates of selected fiat currencies by using quantitative analysis methods. Research methodology – the importance, risks/opportunities are examined by studying scientific literature regarding cryptocurrencies and decentralization. The influence of bitcoins itself is examined by using regression analysis, ANOVA, descriptive statistics, correlation matrix, and VIF. Findings – impart negative relation between Bitcoin money supply and exchange rates (USD/EUR) and a positive relation between Bitcoin inflation rate and exchange rates (USD/EUR). However, the actual influence is too negligible to make any significant affection for the conventional financial sector yet digitalization and decentralization are imminent. Research limitations – only a few analyses have been conducted in a quantitative manner regarding cryptocurrencies impact. The influence of cryptocurrencies increased from 2011; phenomenon lacks long time data and examples to conduct an analysis model that applies to all assumptions without exceptions. Practical implications – enterprises can embrace decentralization and digital money to keep up with the fast-growing market changes, improve transparency, and reduce costs. Close relation with fintech is indispensable; it promotes economic growth and accelerates the development of advanced operating practices. Originality/Value – the interest in digital money and peer-to-peer payments constantly occupy greater importance of financial market and trading manner. Their influence is widely discussed but lacks quantitative researches based on actual historical data

Résumé :

A introdução da instrução OP_RETURN na Bitcoin possibilitou a inserção de dados de qualquer formato em transações. Este trabalho analisa o conteúdo da instrução em transações realizadas entre 2014 e 2019 e busca traçar um comparativo entre tais conteúdos com o perfil dos usuários responsáveis pelas transações. Os resultados mostram que a maioria das transações que utilizam a instrução OP_RETURN foram mapeadas em protocolos desconhecidos. Acerca do conteúdo legível presente em tal campo, foram encontrados potenciais novos protocolos, URLs relacionadas a torrents, memes e marcações de eventos relacionados à Bitcoins.

Résumé :

Bitcoin, which emerged in 2008 and is now being used rapidly in various sectors, is a crypto currency. Bitcoin was revealed by Satoshi Nakamoto (who or who is not specific to the person or a group). An official or private regulator is exported independently of the institution and therefore has no guarantee. Bitcoin was first used in the market in 2009. Although more than one crypto currency has emerged, Bitcoin has maintained its leadership since its release. However, in the years ahead, another crypto currency, Ethereum, will also go ahead of Bitcoin. Although there are countries that are prohibited to be used in countries of the world, the number of countries in which it is used is increasing day by day. In Turkey, shipping fees, employee salaries, cost of books, such as food shopping are being used in many fields.

Résumé :

In recent years, bitcoin has become a very attractive investment in financial industry, which is not controlled by governments, but is based on trust between transfers under the technology of block chain. Hence, forecasting future bitcoin cryptocurrency values is a problem that has attracted the attention of many researchers in the field, while proving to be a very challenging problem. This work presents an experimental analysis using LSTM and GRUs for forecasting bitcoin values in a minute-granulated time for the entire next day. To this end we also present our methodology for conducting the experiments. The final goal is to create the core of a financial prediction tool around the RNNs. In our experiments, we achieved interesting results such as a SMAPE of 0.0002, a RMSE of US$ 3.844 and a rRMSE of 0.0028 in a day where bitcoin rates vary from US$ 13.2K and US$ 14.6K, surpassing the results of SMAPE found in the literature and proposed limit of SMAPE smaller than 0.007 for forecasts.

Résumé :

Apesar do crescente interesse em cripto moedas, tanto indústria quanto a academia sentem falta de análises quantitativas desses sistemas. Neste trabalho, caracterizamos o Bitcoin, um dos mais populares sistemas de cripto moedas, sob a ótica quantitativa. Visamos métricas importantes relacionadas a transações, como a probabilidade uma transação ser confirmada e o tempo decorrido para essa confirmação. Nossos resultados mostram que há um número não negligenciável de transações que não são confirmadas 24 horas após serem postadas na rede. Nesse caso, nós observamos uma alta correlação entre a taxa de uma transação, seu volume e a suspeita de que a transação não será confirmada. O trabalho mostra que transações do Bitcoin geralmente são confirmadas em períodos curtos, mas ainda assim, muito acima de tempos usuais de sistemas de cartão de crédito. Finalmente, nós provemos uma análise de nível de atividade simples, comparando um período importante na existência do sistema do Bitcoin –o fechamento do Silk Road– e um peróodo subsequente. Em resumo, concluimos que a rede Bitcoin se apresenta resiliente e não é dependente de hubs altamente centralizados.

Résumé :

The attempts to create an adequate model of socio-economic critical events, which, as it has been historically proven, are almost permanent, were, are and will always be made. Actually, it is a supertask, impossible to solve. However, the potentially useful solutions, local in time or other socio-economic logistic coordinates, are possible. In fact, they have to be the object of interest for a real and effective economic science. Econophysics is a young interdisciplinary scientific field, which developed and acquired its name at the end of the last century. Quantum econophysics, a direction distinguished by the use of mathematical apparatus of quantum mechanics as well as its fundamental conceptual ideas and relativistic aspects, developed within its boundaries just a couple of years later, in the first decade of the 21-st century.
