...BitCoin the Future of Currency Currency is basically anything that is accepted as a medium for exchange. The common concept of currency is a physical note or coin of a certain denomination regulated and guaranteed by particular government or bank. Everyone around the world uses and depends on currency on a daily basis, hundreds of millions of transactions transacted by hundreds of millions of people whose individual wealth depends on the stability of their currency. The stability of any currency is dependent on many economic factors the most implicit being the stability of the issuing government. If the government who is backing the tender is unstable then the value of its money will directly be affected. Another huge factor in the value of a countries currency is inflation. Inflation is dependent on many factors, most of which are subsequent to the nature of an economic cycle. Some inflation is a by-product of the regulation, de-regulation and/or government monetary policy. What if there was a new currency that was not associated with a nation, government or bank? What if there was unified currency that allowed the wealth of one person to directly compare or exchange with to the wealth of another regardless of geographic location? This “new” currency has recently been developed and it is called the Bitcoin. The Bitcoin and its concept is extremely progressive and is not considered a savior currency that will solve any monetary problems; however, this paper will outline the...

...BITCOINS: A VIRTUAL CURRENCY Submitted to- Professor Dilip Thosar Submitted by- Chidansh Choudhary Rashi Taneja Rashmi Khinvasara Ridhima Agarwal Sahitya Kalidindi Tejal Bhandari Date of submission: 24th December ‘13 EXECUTIVE SUMMARY: Virtual currencies are increasingly becoming a part of not only the virtual world but also in the real world. There are various problems associated with virtual currencies. Due to its similar nature to real currency, a lot of questions have risen regarding its acceptance among the people in the market, and the reliability factor. In the following paper, we have discussed the different types of virtual currencies based on their exchange factor. Bitcoins, a type 3 virtual currency is one of the most popular crypto currencies. We have discussed the characteristics and the process of transacting Bitcoins in detail, emphasizing on the pros and cons of its usage. We have also compared it with the ‘fiat’ money and mentioned its legal aspects. In the end we have mentioned a few areas for further research in relation to Bitcoins.

...Bitcoin is a software-based online payment system described by Satoshi Nakamotoin 2008 and introduced as open-source software in 2009.Payments are recorded in a public ledger using its own unit of account,which is also called bitcoin.Payments work peer-to-peer without a central repository or single administrator, which has led the US Treasury to call bitcoin a decentralized virtual currency.Although its status as a currency is disputed, media reports often refer to bitcoin as a cryptocurrency or digital currency Bitcoins are created as a reward for payment processing work in which users offer their computing power to verify and record payments into the public ledger. Called mining, individuals or companies engage in this activity in exchange for transaction fees and newly created bitcoins.Besides mining, bitcoins can be obtained in exchange for fiat money, products, and services. Users can send and receive bitcoins electronically for an optional transaction fee using wallet software on a personal computer, mobile device, or a web application. Bitcoin as a form of payment for products and services has seen growth,and merchants have an incentive to accept the digital currency because fees are lower than the 2–3% typically imposed by credit card processors. The European Banking Authority has warned that bitcoin lacks consumer protections.Unlike credit cards, any fees are paid by the purchaser not the vendor. Bitcoins can be stolen and chargebacks are impossible. Commercial...

...Page 1: Invented in 2008, Bitcoin is not the first attempt at an all-digital, cryptographically based currency. Others have existed in one form or another for nearly fifty years, but have either failed to take off or dramatically crashed and burned. Bitcoin is the first cryptocurrency with the deep structure, wide adoption, and trading momentum to achieve escape velocity. In practice, Bitcoin blends credit cards' ease of digital transfer with the relative anonymity of a cash handoff. Like all currencies, the problems it poses are both practical and metaphysical; like cash or credit, Bitcoin is somehow both more and less real than the goods it is traded for. Until now, the most well-known of these goods have been illegal drugs, like those on Silk Road. But the drug marketplace's shutdown gives Bitcoin a chance to gain some much-needed legitimacy. Page2: Bitcoin's future potential was a hot topic last year at emTech, an MIT conference on emerging technologies. In a panel hosted by MIT Technology Review's Tom Simonite, MIT economist David Johnson and BitPay CEO Stephen Pair discussed Bitcoin's complex relationship with paper currencies, credit, and state authority. Johnson noted that buyers and sellers, banks and governments all care deeply about what money is used for. Money's use carries associations of value, which in turn helps establish whether a currency, a payment form, and a social model for transactions are legitimate. "It's hard to bring any of them on board if the money...

...BITCOINS (BTC) I. What are Bitcoins? • A currency that uses cryptographic techniques to allow money transfers directly between peers, rather than through a central authority like a bank. Bitcoin has been called a cryptocurrency because it is decentralized and uses cryptography to control transactions and prevent double-spending • Virtual currency designed for digital realm, generated using mining. • Mining means devoting computing resources to finding "blocks" of Bitcoins. Mining is very computationally intensive, to the point that any computer without a powerful graphics card is unlikely to mine any bitcoins in less than a few years. • “Gold for Nerds” II. Who created/invented Bitcoins? • Satoshi Nakamoto (alias) III. When did this Bitcoins created? • 2009 IV. What countries are investing in Bitcoins? • It seems like the majority of the activity comes from the US and China, with Australia, Japan, Europe and Brazil also regularly investing. (Nov. 18, 2013) V. Why did he created Bitcoins? • Satoshi Nakamoto wanted people to be able to exchange money electronically and securely without the need for a third party, such as a bank. He based Bitcoin on cryptographic techniques that allow you to be sure the money you receive is genuine, even if you don’t trust the sender. VI. How is it being created? • Through the used of complex computer algorithm and a software called “TOR” VII. How to mine Bitcoins? • To mine bitcoins, one must solve a 64-digit computer...

...concerns about the anonymity and decentralized regulation of Bitcoin leading to an open door for the criminal element. While the reasoning behind the belief is sound, Bitcoin is not the criminal dream currency that naysayers would have you believe. All of the owners of a bitcoin wallet are only referred to by an 34 character alphanumeric address. However these address do not provide the anonymity you might expect. According to Jermey Kirk of PCWorld, “Using special algorithms, researchers were able to associate large numbers of seemingly anonymous bitcoins addresses with certain major services such as exchanges and payment processors.“ The FBI has also been successful in catching criminals who would use Bitcoin for malevolent purposes. Although the FBI wouldn’t reveal how they accomplished this feat, Forbes magazine did report the following: ‘The FBI official wouldn’t say how the agency had determined that the Bitcoin “wallet”–a collection of Bitcoins at a single address in the Bitcoin network–belonged to Ulbricht, but that it was sure they were his. “This is his wallet,” said the FBI official. “We seized this from DPR,” the official added, referring to the pseudonym “the Dread Pirate Roberts,” which prosecutors say Ulbricht allegedly used while running the Silk Road (Greenberg).’ The reason Bitcoin does not provide the anonymity you might expect is because of its very nature. The same features of Bitcoin that allow for it to be simultaneously secure and decentralized...

... these so-‐called ‘cryptocurrencies,’ such as transaction anonymity and irreversibility of payments, have made them extremely attractive to cybercriminals, drug dealers, money launderers and those involved in global terrorist funding. The most popular crypto currency today is the bitcoin. In the medieval ages, the Silk Road was used by traders for commerce between the Oriental and European world. It was used by Marco Polo to discover Xanadu, the court of the Great Kublai Khan. In the modern era, a new ‘Silk Road’ had emerged, one that was used by traders of illicit substances to fund terrorist activities through the 'Deep Web' i.e. parts of the Internet one should never visit. The currency of their illegal trade is the Bitcoin. Though the Silk Road has been destroyed by the efforts of the U.S. Government, the Deep Web is still very much in...

...Invented in January of 2009, Bitcoin is the world’s first online digital crypto-currency. Rather than relying on central authorities, Bitcoin uses cryptography to control its creation and management. In today’s day and age, cryptography is heavily based on mathematical theory, which Bitcoin creators used to create computational algorithms as a means of securing electronic Bitcoin transactions. From a globalization perspective, the dramatic rise of Bitcoins is of particular importance because of the threat it poses to the centralized global monetary system, as well as central banks of governments all over the world. For the basis of this report we will examine two reputable news sources, the British Broadcasting Corporation (BBC) and the Canadian Broadcasting Corporation (CBC), and review their coverage on Bitcoins, to produce an in depth analytical analysis of the global impact that this decentralised digital currency poses. Brief Introduction into the Background of Bitcoins In 2009 when Bitcoins were first unveiled to the global market, it was introduced as an alternative to the failing fiscal policy of the global monetary system, which was seen as a catalyst for guiding the world into the 2008 recession. Both news outlets recognized developer or developers, Satoshi Nakamoto, as the pseudonym for the creator of the Bitcoin protocol, which is based on “a fundamental critique of the world’s monetary system” (Mendoza, 2012, para. 4). Nakamoto expanded on this critique through...

...Overview Society ismoving from a cash driven to a electronic payment system for the purchase or use of goods and services. The internet and mobile devices have become the market place of choice for transactions. Cash transactions are not possible through this election mercantile system. Bitcoin has risen to fill the need for electronic transactions. Bitcoin is a form ofdigital currency. Bitcoin has no government and no source of backed asset such as gold backing. The use of digital currency is being driven by several different issues. Such as the rise of rebellion of consumers who are seeking refuge from banks and taxation by governments. Consumers are losing faith due to the liquidation and taxation of the value of government back currencies. Bitcoin has become a currency that consumers can use like cash over the internet to avoid recording of the transaction. Another use is for payment of illegal activities anonymously. This report researches the rise and use of bitcoins and how it will challenge central government backed currencies.

... MEMORANDOM TO: Paul Pascal, President FROM: Melanie Soto, Chief Technology Officer DATE: April 21, 2014 RE: Bitcoin Research Introduction: What is Bitcoin? First to answer that question, Bitcoin is another way the average consumer can sell and buy products. The way bitcoin is used is through any computer with Internet connection. As long as you have a computer you can purchase and sell items. A benefit that this has is that the accounts aren’t managed through third parties or banks therefore you can send and receive transactions with a click of a button. There are two ways that you can obtain bitcoins. One way is through mining. You have an electronic wallet on your desktop, laptop, iPad, etc. . This wallet keeps track of how many bitcoins you have and you can than start mining. Mining is when you allow you join a pool that links with other people who are mining to generate bitcoin money with the help of each other’s servers. The second way is to actually purchase a bitcoin. Problem: There are numerous ways that you can purchase Bitcoins but it all depends on which exchange process you use to purchase them. Overall bitcoin is very easy to maneuver but the actual value is not so stable. Since there is a certain amount of bitcoins that were made the value of the currency fluctuates. Meaning if the coins are in popular demands than they are going to be worth more because more people are trying to...
