FOREIGN TRADE UNIVERSITY -*** - MONEY AND BANKING ASSIGNMENT Subject: IS CRYPTOCURRENCY THE FUTURE OF MONEY? Lecturer : Nguyễn Thị Hoàng Anh Class : K58CLC4 Member list : Phạm Hoàng Tuấn Trung Lê Mai Khánh Sơn Huỳnh Thanh Thảo Trần Thanh Tùng Phạm Gia Thịnh Ho Chi Minh, March 3, 2021 Abstract In last decades, digital currencies have been widely traded throughout the world With the continuous development of cryptocurrencies, especially the slump of Bitcoin price in last months Many in the cryptocurrency community have spent years predicting that digital currencies will someday take the place of fiat currencies All things we mention in this report based on our knowledge, theories and information searched on the Internet This report gives an overall introduction of cryptocurrencies After that, we analyze pros and cons of digital currencies, which may give an overview whether they can become leading currencies in the future or not Summing up with our research with a conclusion that cryptocurrencies is the future money provided that it can be controlled by central bank While cryptocurrencies have yet to fully take over in the real world in a way that enthusiasts have predicted, there are nonetheless some signs that various currencies are making it in the traditional business space, even if only to a limited extent We will explain further below Table of content Introduction Cryptocurrency explain 2.1 Characteristics of cryptocurrencies 2.1.1 Decentralized 2.1.2 Irreversible & Immutable (cannot be undone) 2.1.3 Volatility 2.2 How does it work?

2.2.1 What is blockchain? A blockchain is an open, distributed ledger that records transactions In practice, it’s a little like a checkbook that’s distributed across countless computers around the world Transactions are recorded in “blocks” that are then linked together on a “chain” of previous cryptocurrency transactions It is like a diary notebook which is written down all things happen day by day Each of pages is similar to a block, and the whole book, a number of pages, creates a blockchain With blockchain, everyone who uses a cryptocurrency has their own copy of this book to create a transaction record Every copy of the blockchain is updated continuously if a new transaction happens so that all records are identical precisely To prevent fraud, each transaction is checked using one of two main validation techniques: proof of work or proof of stake 2.2.2 Proof of work and proof of stake Proof of work is a method of verifying transactions on a blockchain in which an algorithm provides a mathematical problem that computers try to solve as quickly as possible Each computer participates, called miner, gives the solutions for a mathematical puzzle that helps verify a group of transactions — as a block—then adds them to the blockchain ledger The computer that completes it well is rewarded with a small amount of crypto Proof of stake is used for reducing the amount of electrical power necessary to have a quick check transactions, some cryptocurrencies use a proof of stake verification method Using proof of stake, an amount of cryptocurrency they are willing to “stake will set the limitation on the number of transactions which each person can verify When a validator is chosen to verify some new transactions, they will be rewarded with cryptocurrency, it may be the amount of aggregate transaction fees from the block of transactions 2.2.3 The role of Consensus in crypto Both proof of stake and proof of work are all based on consensus mechanisms to verify transactions This means while we use individual users to verify transactions, ledger holders will check and make approval for each transaction 3 Evaluating the money roles of cryptocurrency The question “what is money?” has had an amount of research dedicated to solving it While it has been hard to define exactly in definitive terms what constitutes as money and what doesn’t, it is clear that money is a crucial part of civilization and the human condition Currently, bitcoin does serve as a medium of exchange, however in quite limited capacity It is possible to exchange bitcoin for goods and services in a selected number of retail stores which operate around the world, and bitcoin can also be exchanged for peer-to-peer services by any individual who has a cryptocurrency wallet and is interested in exchanging goods or services for bitcoin However, it should be noted that while the virtual currency can function as a medium of exchange, it does not reflect that the currency would be especially efficient in functioning as a medium of exchange Transactions fees can be another obstacle to the use of cryptocurrencies such as bitcoin as a medium of exchange, as in cases of congested networks and spikes in the number of individuals making transactions, the transaction fees can spike to unusually high values One of the crucial aspects that is essential for any currency or commodity to serve as a store of value, is its ability to retain a stable and somewhat predictable value As discussed earlier, one of the significant obstacles is that the currency has shown to be extremely volatile in the past few years While holders of the currency may have welcomed this radical shift in value when the price of bitcoin was rapidly rising, the flip side of this rise was the expected and inevitable fall The value of cryptocurrency, especially the high volatility can partially be attributed to certain conditional factors, such as investor speculation, new market conditions Perhaps as the cryptocurrency market begins to mature, and the regulatory framework is established and known, the volatility may start to stabilize One issue is that to this date, despite cryptocurrency initially being invented to be used as a payment method, the virtual currency as observed has primarily been widely viewed as a financial investment opportunity, and therefore the value of it has also corresponded to this perspective, the virtual currency market reacts in sync with people’s collective perceptions of it A further global incorporation of cryptocurrency as a payment mechanism, may eventually, alter the public’s perspective of cryptocurrency as an investment opportunity into a form of currency The issue of volatility is of course, also a factor that makes cryptocurrency unable to effectively at this point in time to fulfill the unit of account function of money It is hard to measure any asset in relation to the value of a cryptocurrency such as bitcoin, as the value continues to fluctuate However, in theory, given that the conditions were suitable, cryptocurrency in essence could fulfill the function of both a store of value and unit of account Benefits of cryptocurrencies In recent years, cryptocurrencies, especially Bitcoin-the most trading cryptocurrency, are becoming more popular and valuable in today's payment systems The technical infrastructure of bitcoin creates unparalleled opportunities that cannot be observed in other monetary systems Following is a brief description of the major opportunities of this special kind of currency 4.1 Open Participation Open Participation refers to the availability of the data on the cryptocurrency blockchain to everyone, causing the system to be completely transparent Cryptocurrencies in general, Bitcoin included, allows anyone with an internet connection to get access to these systems This open participation is enabled since Bitcoin is built entirely on verification, eliminating the need of trust In comparison with modern financial institutes and other intermediaries, cryptocurrencies demand trust, not in people but in technology There are certain requirements to open a bank account in almost everywhere in the world, such as being able to present a valid ID document or a passport Cryptocurrencies give groups, that for various reasons are excluded from the traditional financial infrastructure, access to a technical payment system 4.2 Enormous Profit Bitcoin has surged to never-before-seen highs over recent weeks, breaking through to levels that seemed unimaginable just a few months ago Investment on Bitcoin is now more attractive to many investors because they can get extremely high return on investment from Bitcoin This Graph demonstrates the movement of Bitcoin price one year till now Figure 2: Bitcoin Price Fluctuation 02/2020-02/2021 Due to the high profit, more people want to have Bitcoin on their hands, which lead to a trend of Minting Bitcoin Because of the random nature of hashing, achieving an acceptable block is never a guarantee Thus, bitcoin mining is a competitive venture, where miners are awarded new bitcoins for each block successfully hashed and accepted in the blockchain 4.3 Time and Cost Efficient Transaction Processing The complexity of cross-system interaction is one of the biggest limitations of traditional payment methods Making cross-border transactions and bank-to-bank transfers consumes several banking days and eventual transaction fees Bitcoin offers a technical infrastructure to transfer money anywhere in the world at any time Because both parties are connected to the same network, borders are eliminated No matter where on the globe one is located, transactions can be validated and confirmed within an hour, as long as payer and payee have access to a Bitcoin software Therefore, cryptocurrencies are faster, cheaper and easier when doing transactions Limitations of cryptocurrency 5.1 Cryptocurrency Security Bitcoin exchanges are digital and therefore vulnerable to hackers, operational flaws, and malware By hacking a cryptocurrency exchange, hackers can gain access to millions of accounts and wallets where the cryptocurrencies are stored For example, the famous Mt.Gox hacking incident in 2014, which caused the Japanese exchange to close down after millions of dollars in bitcoin were taken These incidents can impact any exchange but pose the biggest threat on the smaller exchanges Since cryptocurrency is not considered as a currency by the US regulatory, these cryptocurrency “banks” are not FDIC insured Therefore, if hackers steal your cryptocurrency, the exchanges will not be responsible for that 5.2 Price Fluctuation Since the beginning, cryptocurrency has had a very volatile nature For example, although Bitcoin is the most liquid cryptocurrency, it is still susceptible to wild price swings over short periods In the incident of Mt Gox’s collapse, Bitcoin’s value fell by more than 50% However, after the FBI’s announcement that it would treat Bitcoin and other virtual currencies as “legitimate financial services,” Bitcoin’s value rose by the same amount In 2017, Bitcoin’s value doubled several times, only to be halved in early 2018, deleting billions in market value overnight While cryptocurrency’s volatility offers short-term gains for traders, it makes the currency unsuitable for more conservative investors with longer time horizons Besides, since cryptocurrency’s value fluctuates from week to week, it’s difficult for consumers to use it as a stable means of exchange 5.3 Lack of regulations Because cryptocurrency has no central issuer, there are no formal entities to protect the owner of cryptocurrency in case of frauds and scams Besides, since it’s the nature of cryptocurrency to protect the owner’s privacy, it can be used to purchase illegal purposes such as purchasing illicit drugs, weapons; be used as a mean of payment in the black market, money laundering,… Conclusion The future is open for cryptocurrencies In an age of technology such as credit cards, debit cards, and online banking are everywhere, the concept of digital currency is not as far-fetched as it might sound Transferring money digitally is very convenient, cheap, and fast However, cryptocurrencies are too complicated and unsafe for mainstream use Since there is little to no demand for a decentralized currency from the average consumer, for it to work as an established currency, an increase in regulation and consumer protection is undoubtedly needed Although this, in turn, will increase cryptocurrency transaction costs and reduce the owner's anonymity, the two most appealing factors Besides, the use of cryptocurrency does not have many applications in the corporate world, decentralization and price volatility also increase bankruptcy risk Cryptocurrencies can increase returns and lower risk in an investment portfolio, still, they are too risky to be considered and a core asset and only useful for diversifying a portfolio In addition, cryptocurrencies lack the liquidity that other fiat currencies have and they are also vulnerable to cyber-attacks and untraceable scams and frauds Cryptocurrency is the future of money provided that it can be controlled by the government Expected to remove the middleman in financial transactions and reduce transaction fees, the technology should reach the scale that fits the vision, now most cryptocurrencies can’t handle more than 100.000 transactions per second Moreover, to become the future of money, big banks and financial institutions must find other profitable positions then they will let cryptocurrency take over their positions in most financial transactions References Shavinn, (2016), Four
