It is shown that the conditional variances of all the five cryptocurrencies are significantly affected by both previous squared errors and past conditional volatility. -
Cryptocurrencies and Blockchain Technology
Cryptocurrencies and blockchain technology Cryptocurrencies and blockchain technology Bitcoin and several of its more prominent cryptocurrency brethren have made headlines, with their popularity as high-risk investments steadily increasing. However, it’s hard to evaluate their risk and return potential as investments without first understanding their use and viability, including their underlying distributed ledger system – blockchain technology. Cryptocurrency Cryptocurrencies are similar to traditional currencies, such as dollars or euros, in that you can use them to purchase some goods and services. However, that’s where the similarities end. Unlike dollars, you can’t hold cryptocurrencies in your hand. They are completely electronic, global, generally unregulated and almost completely anonymous to transact. Although a growing number of merchants are accepting them as payment because of their attractive transaction fees and irrevocable nature, widespread adoption is a long ways away. Lastly, the extreme volatility of cryptocurrencies makes them very much unlike traditional currencies, which are meant to provide a reasonably stable store of value. Despite their unusual properties, there are some practical uses for cryptocurrencies, particularly in developing economies where distrust for banks, high banking fees, high inflation and heavy government capital controls make a currency outside government control popular (similar to how U.S. dollars are highly prized in developing nations, but without the need to physically smuggle them past the border). Unfortunately, because cryptocurrencies are pseudo-anonymous, they are also attractive for those engaging in illegal activities, which is why they often carry a negative stigma. Since governments cannot fully track the flow of money with cryptocurrencies, their ability to tax and prosecute illegal Instances of "Cryptocurrency" Articles activities is limited, which makes them more likely to limit the widespread use of digital currencies. -

A Survey on Volatility Fluctuations in the Decentralized Cryptocurrency Financial Assets
Journal of Risk and Financial Management Review A Survey on Volatility Fluctuations in the Decentralized Cryptocurrency Financial Assets Nikolaos A. Kyriazis Department of Economics, University of Thessaly, 38333 Volos, Greece; [email protected] Abstract: This study is an integrated survey of GARCH methodologies applications on 67 empirical papers that focus on cryptocurrencies. More sophisticated GARCH models are found to better explain the fluctuations in the volatility of cryptocurrencies. The main characteristics and the optimal approaches for modeling returns and volatility of cryptocurrencies are under scrutiny. Moreover, emphasis is placed on interconnectedness and hedging and/or diversifying abilities, measurement of profit-making and risk, efficiency and herding behavior. This leads to fruitful results and sheds light on a broad spectrum of aspects. In-depth analysis is provided of the speculative character of digital currencies and the possibility of improvement of the risk–return trade-off in investors’ portfolios. Overall, it is found that the inclusion of Bitcoin in portfolios with conventional assets could significantly improve the risk–return trade-off of investors’ decisions. Results on whether Bitcoin resembles gold are split. The same is true about whether Bitcoins volatility presents larger reactions to positive or negative shocks. Cryptocurrency markets are found not to be efficient. This study provides a roadmap for researchers and investors as well as authorities.

A Behavioral Economics Approach to Regulating Initial Coin Offerings
A Behavioral Economics Approach to Regulating Initial Coin Offerings NATHAN J. SHERMAN* INTRODUCTION Initial coin offerings (ICOs) are an outgrowth of the cryptocurrency space in which companies raise capital by issuing their own cryptocurrency coin to investors. Although ICOs are an innovative method of raising capital, the growth of the ICO market is troubling considering no investor protection regulations govern the ICO process. Investors pour large amounts of money into these offerings, which are issued by companies that typically have no history of producing a product or revenue, and the prices of coins issued in ICOs are only rising because other investors also funnel money into them.1 This pattern is markedly similar to that of a speculative bubble. A speculative bubble occurs when there are “‘unsustainable increases’ in asset prices caused by investors trading on a pattern of price increases rather than information on fundamental values.”2 In a bubble, “smart money”—informed investors—bid up prices in anticipation of “noise traders” entering the market.3 The noise traders then enter the market due to the psychological biases they encounter in making their investment decisions.4 Eventually, the smart money investors sell their holdings and the bubble bursts. 5 Thus, regulators should create a framework that adequately protects investors in ICOs. The behavioral economics theory of bounded rationality provides insights for building this regulatory framework. Bounded rationality implies that humans make suboptimal choices.6 By understanding the psychological biases that influence investors’ choices, regulators will be able to help investors adopt habits that reduce the harmful effects of speculative bubbles. -

How Global Is the Cryptocurrency Market?
How Global Is The Cryptocurrency Market? Gina C. Pieters Trinity University, Economics Department, San Antonio, Texas, USA University of Cambridge, Judge Business School|Cambridge Centre for Alternative Finance, UK Abstract Despite the size and global reach of crypto-markets we dont know how much individual countries have invested in cryptos (market exposure), what share of the market individual countries account for (market power), or how those two measures are related. Movements originating in high market power countries will impact high exposure countries, representing a new channel for financial contagion. This paper constructs multiple estimates of exposure and power, using purchases by state-issued currencies and including adjustments to account for the purchase of cryptocurrencies by other cryptocurrencies. All measures find that the market is highly concentrated in just three currencies|the US dollar, the South Korean Won, and the Japanese Yen account for over 90% of all crypto transactions. Market expo- sure and market power cannot be explained by economic size, income, financial openness, domestic stock market size, or internet access. This analysis also reveals that a country's Bitcoin market share is not representative of a country's crypto-market share: a warning for regulators or researchers focused exclusively on Bitcoin markets.

Introduction The FSB's initial assessment is that crypto-assets do not pose risks to global financial stability at this time. This is in part because they are small relative to the financial system. Even at their recent peak, their combined global market value was less than 1% of global GDP. -

Two different long- memory methods (R/S analysis and fractional integration) are used to analyse it in the case of the four main cryptocurrencies (BitCoin, LiteCoin, Ripple, Dash) over the sample period 2013-2017. The findings indicate that this market exhibits persistence (there is a positive correlation between its past and future values), and that its degree changes over time. Such predictability represents evidence of market inefficiency: trend trading strategies can be used to generate abnormal profits in the cryptocurrency market.

Price Shocks of Bitcoin and Correlation to Other Cryptocurrency
Price shocks of Bitcoin and correlation to other cryptocurrency Master Thesis Student name: Marko Jelčić ANR:929706 SNR:2016639 November 2018 Supervisor: dr. Ole Wilms Second reader: dr. Fatemeh Hosseini Tash Abstract The purpose of this study is to examine how the correlation between Bitcoin and other cryptocurrencies changes after Bitcoin price shocks that happened in 2017 and early 2018, when the market experienced a great increase and introduced cryptocurrency to the broader public. Using time series data of returns and using 14-day rolling correlations between Bitcoin and nine other cryptocurrencies, the empirical research will focus on correlation shifts. Quantitative analysis was performed on correlations between cryptocurrencies during the aforementioned period, generalized autoregressive conditional heteroskedasticity analysis was performed as well as a thorough analysis on structural breaks in correlation levels between Bitcoin and other cryptocurrencies. Main hypothesis of the thesis is that correlation levels rise after Bitcoin experiences a price shock. The results indicate that the correlation coefficient shifts after every Bitcoin price shock, but not necessarily in an upwards direction. These results have implications on using Bitcoin and other cryptocurrencies in a portfolio and creating a cryptocurrency portfolio itself, especially concerning diversification possibilities in a portfolio consisting of cryptocurrencies alone. After a structural break happens, the portfolio should be readjusted accordingly, whether it was -
The Rise and Fall of Cryptocurrencies
The Rise and Fall of Cryptocurrencies Amir Feder∗ Neil Gandal Berglas School of Economics Berglas School of Economics Tel Aviv University, Israel Tel Aviv University, Israel [email protected] [email protected] JT Hamrick Tyler Moore Tandy School of Computer Science Tandy School of Computer Science The University of Tulsa, USA The University of Tulsa, USA [email protected] [email protected] Marie Vasek Department of Computer Science University of New Mexico, USA [email protected] July 30, 2018 Abstract Since Bitcoin's introduction in 2009, interest in cryptocurrencies has soared. One manifestation of this interest has been the explosion of newly created coins. This paper examines the dynamics of coin creation, competition and destruction in the cryptocurrency industry. In order to conduct the analysis, we develop a methodology to identify peaks in prices and trade volume, as well as when coins are abandoned and subsequently \resurrected". We study trading activity associated with 1 082 coins over a nearly five-year period. We present evidence that the more frequently traded coins experience the biggest price rises. They are also much less likely to be abandoned, that is, to experience a drop in average trading volume to below 1% of a prior peak value. Overall, we find that 44% of publicly-traded coins are abandoned, at least temporarily. 71% of abandoned coins are later resurrected, leaving 18% of coins to fail permanently. We then examine the association between entry and exit and other key variables such as price, volume, and market capitalization in order to analyze and provide intuition underpinning the fundamentals in this market.
