Theoretical and Applied Economics Volume JOa (2014), No. 1(590), pp. 103-114 The issue of competing currencies. Case study - Bitcoin Angela ROGOJANU Bucharest University of Economic Studies angelarogojanu@yahoo.com Liana BADEA Bucharest University of Economic Studies badea.liana@gmail.com Abstract. The complexity and interdependence of the economies of various geographical and political entities have one generic binder - money. The economic history of the last century, replicated in the first decade of our century, can be "written " with money. Indeed, money, a multiple discovery of the civilization in its historical way, was and still is the guardian of hope for prosperity. The disputes about money clearly indicate the need, opportunity and the possibility of monetary competition, which would provide, from the point of view of entrepreneurs, the most suitable production of money based on expectations of their economic preferences. Increasingly more, theorists, practitioners and analysts bring to the fore the issue of simultaneously using the official currency and the digital one. Thus, the issue of the public debate regarding the private money is still of inter-est. Based on these considerations, this paper aims to highlight how the digital currency Bitcoin can meet the challenges of the economic environment, taking into account both the oppor'tunities and the threats to which it is subject, and the records emphasized by the history of economic thought and adapted to the current reality. Keywords: currency, Bitcoin, market, competition, private currency. JEL Classification: B25, MOO. REL Classification: II, 14A. 104 Angela Rogojanu, Liana Badea 1. Introduction Throughout the centuries, the currency has been a topic of interest for both academia and the policy makers. The currency issue goes beyond time, it being the subject of numerous studies and regulations since the earliest times. In antiquity philosophers such as Xenophon, Plato and Aristotle tried to unravel the key issues concerning the value, the shape, the functions and the way currency circulates on the market; studies have advanced with the times (Dobrescu and Paicu, 2012), and economists have refined their theories, but the issue regarding the currency is far from being finally answered. Nowadays, we are talking more and more in different geographical areas about using a new currency called Bitcoin, a few economists bringing again to the fore an essay that seemed long forgotten, "Denationalization ofMoney-The Argument Refined: An Analysis of the Theory and Practice of Concurrent Currencies ", written by Friedrich August von Hayek, Nobel Laureate in Economics in 1974. In 1976, Friedrich August von Hayek started from an idea that emphasized the excess/deficit existing on the monetary market, showing that infiation and its socio-economic consequences are usually presented as being the result of the excess due to market, where the economic recovery measures require corrective intervention of the government. At that time, Hayek's approach has given rise to heated disputes in academia and beyond, starting from the statements he made from the very beginning of the introduction: "The further pursuit of the suggestion that government should be deprived of its monopoly of the issue of money opened the most fascinating theoretical vistas and showed the possibility of arrangements which have never been considered. " (Hayek, 2006, p.7) Hayek argued that, in fact, it is a market gap created by the monopoly of the state over money, thus the solution would be the denationalization of money. About the solution offered by Hayek there were a lot of discussions both within the Austrian School of Economics and beyond. Speaking about the essay of Hayek, Murray Rothbard argued that: "The best known proposal to separate money from the state is that of F.A. Hayek and his followers. Hayek's "denationalization of money" would eliminate legal tender laws, and allow every individual and organization to issue its own currency, as paper tickets with its own names and marks attached. " (Rothbard, 2003) The belief of Hayek that free competition between private producers of currency is the best way to achieve a healthy currency has generated a number of critics both outside and inside the Austrian School of Economics. Murray Rothbard himself claimed that: "Hayek's plan would have merit if the thing — the commodity - we call "money" were similar to all other goods and services. [...JThere is a crucial difference, however, between money and all other goods The issue of competing currencies. Case study - Bitcoin 105 and services. All other goods, whether they be postal service or candy bars or personal computers, are desired for their own sake, for the utility and value that they yield to consumers. Consumers are therefore able to weigh these utilities against one another on their own personal scales of value. Money, however, is desired not for its own sake, but precisely because it already functions as money, so that everyone is confident that the money commodity will be readily accepted by any and all in exchange. People eagerly accept paper tickets marked "dollars " not for their aesthetic value, but because they are sure that they will be able to sell those tickets for the goods and services they desire. They can only be sure in that way when the particular name, "dollar, " is already in use as money. Hayek is surely correct that a free market economy and a devotion to the right of private property requires that everyone be permitted to issue whatever proposed currency names and tickets they wish. Hayek should be free to issue Hayeks or Ducats, and I to issue Rothbards or whatever. But issuance and acceptance are two very different matters. No one will accept new currency tickets, as they well might new postal organizations or new computers. These names will not be chosen as currencies precisely because they have not been used as money, or for any other purpose, before. " (Rothbard, 2003) Although it has long been criticized Hayek's view, considered a utopia, it has complied with stated belief to lead to the final task of the economist theorist: ".../ strongly feel that the chief task of the economic theorist or political philosopher should be to operate on public opinion to make politically possible what today may be politically impossible, and that in consequence the objection that my proposals are at present impracticable does not in the least deter me from developing them. " (Hayek, 2006, p. 11) Based on the controversies conceraing the competition between the official and centralized cunency and other private currency (regardless of how much trust would enjoy and regardless the favorable public perception), the financial and banking institutions, experienced users of the common currency, will not willingly accept to trade a virtual currency with zero transaction costs, but they cannot prevent people to prefer another method of making payments. Over time, an alteraative currency made its place on the market, both in developed economies and emerging economies. The alternative currency circulated in different time periods in different geographic, physical or virtual areas. Below are listed a few such attempts. • QQ - Chinese currency launched in a network on the Internet. After the advent and use of this currency in China was bora a black market where the virtual currency was exchanged for the real one. In 2007 there were approximated transaction amounting of nearly 6.8 billion Yuan (one billion Angela Rogojanu, Liana Badea dollars) realized with QQ. The Chinese govemment has intei-vened and in 2008 there were withdrawn large amounts of cash of the QQ market (Business Magazin, 2009). M-PESA used by Kenyans to change minutes into cash. The payment, for an economic good is done by transferring a number of minutes to the phone of the cash register. Every day, through the M-PESA system there' were made transactions totaling 10 million dollars, which means about $ 3.6 billion annually (Business Magazin, 2009). Tem - a currency used from 2010 in Volos, a Greek port city. The established system implies people to use Tem units in order to exchange products, goods and services - cleaning, cooking, repairs, teaching, baby-sitting and technical assistance. The system has been improved, and the rate of exchange Tem/ Euro is at parity, as has always been since the beginning (Dumitru, 2013). Sano ('a currency for barter in S iros' worth an hour of work) - the inhabitants of the Greek island of Siros realize mutual exchange of services or products and digitally record the transactions (The EpochTimes Romania, 2012). "Peaches" - from the end of November 2013 in Montreuil, France, people are discussing about a new currency, which is a French way of ensuring that "transactions are not lost in the banking system" and the currency is meant "to promote the local trade". (Dumitm, 2013). "Bees" - in Villeneuve sur Lot they are used since January 2010, when a bee had the same value as an euro. Every six months, "the bee" was depreciated by 2%. (Dumitm, 2013). In Toulouse, beside euro it is used a currency called metaphorically "soil" (Dumitm, 2013). In Vaucluse, euro circulates alongside the "wheel" (Dumitm, 2013). In Romans-sur-Isere the French are using "the measure", in Angers - "the muse" and in Brittany there have been introduced "the Heol" (Dumitm, 2013). In Barcelona there are issued checks in "hours", used subsequently in order to purchase goods or services. The model called "time bank" has spread to otlier Spanish regions. "In Malaga, the system functions exclusively online. In Vilanova i la Geltm, the locals use a variety of credit card made of paper, which uses an altemative currency, accepted by just a few stores. Some cities have begun to accept the peseta again, these being the national currency before joining the euro zone; in the present context, the central bank in Madrid estimates that Spanish people still own pesetas amounting $ 2.4 billion that they have not surrendered before the introduction of the euro." (Dumitm, 2013) In Mataelpino city and 10 other towns in the Sierra Norte region, people are paying with "moras" (blackberries). In the capital city of Madrid are also accepted "boniatos" (sweet potatoes) and "bivs"; in Bilbao "gitas" and in The issue of competing currencies. Case study - Bitcoin 107 Valladolid "neighbors". In Sevilla were issued "jaras" and "cougars", in Catalonia "the echoes" have spread and the Basque Country uses "eusko". (Dumitru, 2013) A special category of alternative cun-encies is the crypto-currency, which represents a digital currency being peer-to-peer, decentralized, whose circulation is based on the principles of cryptography to validate transactions and currency generation itself. Among the crypto-currencies currently used there are: Bitcoin, Litecoin, Peercoin, Namecoin, Novacoin etc. One of the most recent publicized such currency is the Bitcoin, which will be presented in the following sections. 2. What is the Bitcoin? The digital currency called Bitcoin falls into the pattern of the private currency described by FA von Hayek, except the cyberspace in which it circulates. The Bitcoin was issued in the beginning of 2009 by an anonymous entity, working under the name "Satoshi Nakamoto" after the same entity in 2008 introduced the concept in a study. Bitcoin uses a database, relying on 20,000 nodes of a network of peer-to-peer with the purpose of the inventory of transactions. Cryptography is used, so that the currency is very often called a crypto-currency. The goal of using cryptography is to provide the core of the security ftanctions - Bitcoins can be spent only by the one who owns them and this thing can be done only once (Hall, 2013). The relationship between Bitcoin and a traditional currency is still not regulated; therefore, the responsibility for the way Bitcoins are circulating on the market lies to the economic agents who use Bitcoin. The digital currency can be obtained by: • The operation called "mining" - the personal computer is programmed to "dig" for Bitcoins. After the computer solves several problems, the owner will compete with other users to generate the number that the Bitcoin network is looking for. If the computer of the concerned person finds the number, then it will receive 25 at 10-minute period is generated every 25 Bitcoin. It should be noted the terminology used, which refers to the mining practiced in the heyday of the gold coin for its extraction. Also important to mentioning that the "mining" is quite expensive and involves the use of high performance computers, which use a lot of energy. • Exchanging Bitcoins with real money, on the assumption that the rate of exchange is set based on the free meeting of demand and supply (Plassaras, 2013, p. 386). It should be noted that although Bitcoin does not have intrinsic value, over time, the exchange rate reached highs. Thus, in January 2013, one 108 Angela Rogojanu, Liana Badea Bitcoin was changed to $ 20; on 10 April, the exchange rate reached 266 dollars and after three days it dropped to $ 54 (Husler et al., 2012, p. 305). • Exchanging goods Bitcoin newly generated (Hall, 2013). Currently/services for Bitcoin (Plassaras, 2013, p. 386). The novelty that comes with the use of Bitcoin is a decentralized system, in other words there is no involvement of any central bank or of any government. The system was programmed so as to provide a limited number of coins in a certain time. It is expected, based on the generation algorithm of the Bitcoin that the total amount (21 million) provided by the system to be reached in 2025 according to some authors (Plassaras, 2013, p. 387), or in 2140, according to others (Hall, 2013). In order to store the Bitcoins, a personal computer can be used, which will include a "wallet file" or the storage can be done using a service of the type "wallet" belonging to a third party. In both cases the money can be sent via the Internet to anyone with a Bitcoin address. In other words, Bitcoin is a smart scheme to make payments on the Internet without paying fees (for example, if you pay by card over the Internet, in our country the issuing bank charges the dealer with a commission of 1-2%, and in the USA 2 - 3%). The currency has spread pretty quickly, today being already recognized and carrying out transactions in different countries. If in the early days of the existence of digital currency, a personal computer could occasionally get a few coins, nowadays the generation process is dominated by professionals who possess computers built in order to ensure an amazing compufing power. At the price of 122 dollars on a Bitcoin, the 3600 coins generated daily are worth over 430,000 dollars. The whole "economy" of Bitcoin has a market capitalization of about 1.4 billion dollars (Urzicâ, 2013). Bitcoin has acquired increasingly more ground in the real economy; the currency is accepted for payment throughout many sites such as Wordpress.com, Reddit or new file hosting service on the web Mega. The increasing number of users has been infiuenced by the advantages the cyberspace provides and by the diminishing trust in the banking system. For example, in Cyprus and in Canada were inaugurated ATMs through which real currencies can be exchanged for virtual currency (Abrihan, 2013). In addition, also in Cyprus was identified the first university in the world that accepts the Bitcoin for paying the university fees, its representaüves stafing that the strategy used is to immediately convert the alternative currency into Euro (Szoldra, 2013). In China, despite expectations, an increasing interest in using the Bitcoin can be noted. In Gennany, the Bitcoin is not classified as e-money or foreign currency, but is seen as a financial instrument subject to banking regulations, instrument from which the Gennan government aims to gain by taxing the use of virtual currency win7 高亮 win7 高亮 win7 高亮 win7 高亮 win7 高亮 The issue of competing currencies. Case study - Bitcoin 109 (Neroth, 2013). The fact that Gemiany has adopted the use of private money is interpreted as a safety measure taken in the event that the European single currency would not survive. Worldwide it is noted that a number of increasingly large businesses begin to adopt the new currency. Also in Romania there are merchants who accept the payment of services / goods offered with Bitcoin. The fact'is that in what is called human routine money bring together some of the most diverse interests so that private money could be preferred if it had the qualities of the official ones (trust, rarity, acceptability and inalterability, manageability etc..) and if in addition to these, private money would provide full respect for property. The scientific and practical message of private digital money correlates the rigor and pragmatism with the advantage of high technologies in the production and processing of information, and Bitcoin or howsoever called digital currency, could be viewed as the most suitable means of payment. 3. Advantages of using Bitcoin F.A. von Hayek asserted about the capacity of the private currency to compete with the currency issued by the state that has a number of advantages that can ease its existence on the market. The Nobel Prize Laureate for Economics argued that: "a) a money generally expected to preserve its purchasing power approximately constant would be in continuous demand so long as the people were free to use it, b) with such a continuing demand depending on success in keeping the value of the currency constant one could trust the issuing hanks to make every effort to achieve this better than would any monopolist who runs no risk by depreciating his money, c) the issuing institution could achieve this result by regulating the quantity of its issue. d) such a regulation of the quantity of each currency would constitute the best of all practicable methods of regulating the quantity of media of exchange for all possible purposes. " (Hayek, 2006, p. 41) Starting fi-om the advantages of the private currency, listed by Hayek, we will try to highlight the strengths of Bitcoin. • The digital currency does not require the physical presence of traders for a transaction, therefore the use of Bitcoin saves a lot of time for those involved (Plassaras, 2013,p. 387). • Transactions can be done anytime and anywhere, providing business fiexibility. • Issuance expenditures are prevented, as well as the costs of transportation, storage and security which arise when putting traditional currency into circulation. Annually in the USA there are spent about 60 billion dollars for such activities (Plassaras, 2013, p. 387). In addition, bureaucracy is avoided for the money issuance (Frâncu, 2011). win7 高亮 win7 高亮 win7 高亮 win7 高亮 110 Angela Rogojanu, Liana Badea • Facilitates transactions anywhere in the world, thus avoiding costs related to foreign exchange trading. It is enough to possess a quantify of Bitcoin to perform operations in Japan, USA, France, etc. • It has the same qualities as gold, simulating rarify very well. In order to produce a Bitcoin, equipment and power are required, and the amount of Bitcoin is limited to 21 million. • Do not assume the payment of commissions that banks typically charge. Transfers are facilitated directly without using a payment processor between nodes. The Bitcoin client transmits the transaction to the nearest nodes which in tura propagates the transaction in the network. Corrapt or invalid transactions are rejected by honest nodes. Transactions are usually free, but a fee is likely to occur in the case of other nodes for the prioritization of transaction processing. • Bitcoin use does not generate inflation. It is well known that limiting the money supply can be seen as an advantage in fighting against inflation (Burgh
