Abstract

The Covid-19 bear market presents the frst acute market losses since active trading of Bitcoin began. This market downturn provides a timely test of the frequently expounded safe haven properties of Bitcoin. In this paper, we show that Bitcoin does not act as a safe haven, instead decreasing in price in lockstep with the S&P 500 as the crisis develops.

Introduction
This paper will discuss why Bitcoin, a groundbreaking and experimental cryptocurrency protocol, has flourished in Argentina’s modern economic climate. Argentina has long been plagued by high inflation rates.
Argentina has historically used the strength of the US dollar to stabilize its fiat currency, the Argentine peso, in times of inflation. Most recently, former President Cristina Fernández de Kirchner attempted to stabilize inflation by setting the exchange rate between the peso and the dollar, and then strictly limiting access to dollars within Argentina to avoid depleting the country’s reserves of US dollars, the Central Bank’s most stable asset. These currency controls made it almost impossible for Argentines to obtain US dollars outside of the black market. Because Argentines had been reliant on the US dollar to keep their wealth secure in the face of high inflation, there was a need for some type of stable currency in which to place wealth. Additionally, Argentina had trouble printing enough cash and coins to serve its population.
For many Argentines, Bitcoin represented a solution to both these problems.
And while the new President Mauricio Macri has since relaxed these currency controls, Bitcoin’s advocates are certain that there is still a future for this cryptocurrency both within Argentina and worldwide. Bitcoin is not a trend, but rather an innovation that will only increase in relevance for the global economy.

Abstract
A crypto currency is a digital resource which act as a medium of exchange that uses cryptography to make its transactions secure. Cryptocurrencies are subset of digital currencies. In this economic world, different number of virtual currencies available over the internet. A new digital currency may create at any time. By market capitalization, Bitcoin is the largest blockchain network followed by many other cryptocurrencies like Ripple,Ethereum,Cardano and Litecoin.
Bitcoin, was created in 2009, first decentralised crypto currency, since then only the numerous other crypto currencies have been created. These are frequently called altcoins. Bitcoin and its products use distributed financial control as opposite to centralised electronic money/central banking systems. The distributed system uses the blockchain transaction using distributed ledger. Today cryptocurrencies have become a globally trending economic phenomenon known to most people, banks, governments and many companies are aware of the importance. Bitcoins were in the news recently after a massive global ransomware attack “WannaCry‟‟ which hit systems in over 100 countries. To unlock the affected devices cybercriminals demanded a fee of about $300 in cryptocurrencies like bitcoin.

Abstract
In this paper, the price fluctuations of Bitcoin under speculative environment is studied. It has been seen that the market trend points out an existence of a speculative bubble. Over the course of the period from 2014 to 2018, the trend in price movements of bitcoin has proved to be strongly speculative. In that regard, investors might be curious about what drivers might be instrumental in these speculative price changes. After reviewing of NPV, it was seen that NPV is not applicable to the case of cryptocurrencies due to their nature and lack of free cash flows to base the asset valuation to some fundamental facts. Later, LPPL model is reviewed, however, that also proved to be insufficient since it does not reflect the investor speculations and inform much about price dynamics regarding ehavioral finance principles. Then, some papers from the past price fluctuations of bitcoin (for the period from 2010 to 2013) was reviewed and three key variables were determined which might explain price movements. Public interest towards Bitcoin as interest-driven, regulatory and political news about cryptocurrencies as event-driven and VIX as overall investor approach to Bitcoin market have been taken. After running regressions, the only significant variable happened to be public interest and popularity of Bitcoin. Although, for some cases, VIX variable also explain price fluctuations for some intervals, in none of the cases event-driven variable has long- terms effect on price fluctuations under speculative environment. Lastly, a robustness test is also handled considering the “weekend effect” and it has been seen public interest variable again proved to be a significant price determinant.

ABSTRACT
Bitcoin is a distributed system. The dilemma it poses to the legal systems is that it is hardly possible to regulate a distributed network in a centralized fashion, as decentralized cryptocurrencies are antithetical to the existing centralized structure of monetary and financial regulation. This article proposes a more nuanced policy recommendation for regulatory intervention in the cryptocurrency ecosystem, which relies on a decentralized regulatory architecture built upon the existing regulatory infrastructure and makes use of the existing and emerging middlemen. It argues that instead of regulating the technology or the cryptocurrencies at the code or protocol layer, the regulation should target their use-cases. Such a regulatory strategy can be implemented through directing the edicts of regulation towards the middlemen and can be enforced by the existing financial market participants and traditional gatekeepers such as banks, payment service providers and exchanges, as well as large and centralized node operators and miners.

Abstract
Bitcoin is a digital currency based on a peer-to-peer 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. Despite criticisms about illegal uses and social consequences, it is attracting the interest of the scientific community. The purpose of this work is to define and evaluate the current trends of the literature concerned with the sustainability of bitcoin, considering the environmental impacts, social issues and economic aspects. From the analysis 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. Blockchain, which is the base for a distributed and democratically-sustained public ledger of the transactions, could foster new and challenging opportunities. Sharing the framework of medical data, energy generation and distribution in micro-grids at the citizen level, block-stack and new state-driven cryptocurrencies, may benefit from the wide spread of blockchain-based transactions. Under the perspective of its being a driver of social change, bitcoins and related blockchain technologies may overcome the issues highlighted by numerous detractors.

ABSTRACT
Bitcoin, the digital cryptocurrency, has been celebrated as the future of money on the Internet. Although Bitcoin does present several forward-looking innovations, it also integrates a very old concept into its digital architecture: the mining of precious metals. Even though Bitcoin explicitly invokes mining as a metaphor and gold as an example for understanding the cryptocurrency, there has been little critical work on the connections between Bitcoin and previous metalist currency regimes. The following essay proposes a historical comparison with colonial South American silver mining and the global currency regime based on the New World silver peso it created as a way to interrogate Bitcoin. The comparison with colonial South America, and specifically the silver mining economy around the Cerro Rico de Potosí, will help to develop a historical and political understanding of Bitcoin’s stakes, including questions of resources, labor, energy, and ecology.
Mining and the extractive apparatus that accompanies it always imply massive-scale earthworks that reshape the planet itself, a process known as terraforming. The Potosí comparison will reveal Bitcoin to form part of a similar process of digital primitive accumulation we can provisionally name cryptoforming.

ABSTRACT
This is the first article that studies BitCoin price formation by considering both the traditional determinants of currency price, e.g., market forces of supply and demand, and digital currencies specific factors, e.g., BitCoin attractiveness for investors and users. The conceptual framework is based on the Barro (1979) model, from which we derive testable hypotheses. Using daily data for five years (2009–2015) and applying time-series analytical mechanisms, we find that market forces and BitCoin attractiveness for investors and users have a significant impact on BitCoin price but with variation over time. Our estimates do not support previous findings that macrofinancial developments are driving BitCoin price in the long run.

ABSTRACT
Money is a collective agreement. If enough people come to the same agreement, what they agree upon becomes secondary, whether it be farm animals, gold, diamonds, paper, or simply a code. History proves all these cases to be true. Who knows what the future is going suggest to us as money, once we see digital currencies as ordinary?
The idea of digital currencies has existed for years. However, despite some effort on the part of programmers, none proved viable. Then, less than a decade ago, Bitcoin exploded into the world of cryptocurrency. Now, Bitcoin has become not only a cultural phenomenon, but a political and economic one as well, holding the fiscal eye of the world captive through its tumultuous course. It has currently been widely discussed and used in many developed countries.
However, my hypothesis is that Bitcoin provides a distinct advantage to populations living in underdeveloped and struggling economies, since it is solves the problems of hyperinflation, exchange, counterfeiting, and inaccessibility. This paper also proposes that the three factors that might hinder the widespread adoption of Bitcoin in these struggling economies is lack of infrastructure, unrealized problems with the Bitcoin network itself, and fear of the unknown.
