Booms, busts and heavy-tails: the story of Bitcoin and cryptocurrency markets?Fry, John 05 January 2020 (has links)
Yes / We develop bespoke rational bubble models for Bitcoin and cryptocurrencies that incorporate both heavy tails and the probability of a complete collapse in asset prices. Empirically, we present robustified evidence of bubbles in Bitcoin and Ethereum. Theoretically, we show that liquidity risks may generate heavy-tails in Bitcoin and cryptocurrency markets. Even in the absence of bubbles dramatic booms and busts can occur. We thus sound a timely note of caution.

Negative bubbles and shocks in cryptocurrency marketsFry, John, Cheah, E-T. 03 February 2020 (has links)
Yes / In this paper we draw upon the close relationship between statistical physics and mathematical finance to develop a suite of models for financial bubbles and crashes. The derived models allow for a probabilistic and statistical formulation of econophysics models closely linked to mainstream financial models. Applications include monitoring the stability of financial systems and the subsequent policy implications. We emphasise the timeliness of our contribution with an application to the two largest cryptocurrency markets: Bitcoin and Ripple. Results shed new light on emerging debates over the nature of cryptocurrency markets and competition between rival digital currencies.

Adverse selection in cryptocurrency marketsTiniç, M., Sensoy, A., Akyildirim, Erdinc, Corbet, S. 31 March 2023 (has links)
Yes / This paper investigates the influence that information asymmetry may possess upon the
future volatility, liquidity, market toxicity and returns within cryptocurrency markets. We use
the adverse selection component of the effective spread as a proxy for overall information asymmetry. Using order and trade data from the Bitfinex Exchange, we first document statistically
significant adverse selection costs for major cryptocurrencies. Our results also suggest that adverse selection costs, on average, correspond to ten percent of the estimated effective spread,
indicating an economically significant impact of adverse selection risk on transaction costs in
cryptocurrency markets. We finally document that adverse selection costs are important predictors of intraday volatility, liquidity, market toxicity, and returns. / Türkiye Bilimler Akademisi.

Bitcoin : A study on the determinants of the Bitcoin price developmentSpaans, Jana, Crivellaro, Fabio January 2019 (has links)
Bitcoin is a new evolutionary development within the internet and payment system. Its price has a high volatile nature what brings a lot of attention to this cryptocurrency. This paper investigates the price formation of the Bitcoin by looking at three determinants: speculative position, transaction volume and the utility users obtain from joining the network. To see the correlation between these determinants and the influence it has on the Bitcoin price a multiple regression model has been built over the time period from 2017 to 2019. The model shows that the effect of speculation is heavier than any other variable, reflecting the uncertainty brought by the sensible sentiment of speculators and users.

The Volatility Patterns and Correlation of Cryptocurrencies: Overcoming the Bitcoin's primacy / The Volatility Patterns and Correlation of Cryptocurrencies: Overcoming the Bitcoin's primacyŠembera, Tomáš January 2017 (has links)
The thesis focuses at the evolution of cryptocurrencies or more precisely at the competition process between them in expanding to broader usage. The first main goal of the work is to find out, whether Bitcoin, as the first and still most capitalized cryptocurrency, has an advantage of higher maturity than alternative cryptocurrencies. The second goal is to analyze whether the individual cryptocurrencies are perceived individually by market participants, which could grant the alternative cryptocurrencies an option to compete with Bitcoin by offering better features as safer technology or faster transaction. The analysis of volatility patterns in their exchange rates via various GARCH models suggests that Bitcoin still has advantage in higher maturity. The analysis of the correlation between various alternative cryptocurrencies and Bitcoin finds positive correlation and thus suggests that the cryptocurrencies are rather perceived together.

Assessing the attractiveness of cryptocurrencies in relation to traditional investments in South AfricaLetho, Lehlohonolo 30 July 2019 (has links)
The dissertation examined the effect of cryptocurrencies on the portfolio risk-adjusted returns of traditional and alternative investments using daily arithmetic returns from August 2015 to October 2018 of traditional assets (South African stocks, bonds, currencies), alternative assets (commodities, South African real estate) and cryptocurrencies (Cryptocurrency index (CRIX) and ten other individual cryptocurrencies). This is worth investigating as cryptocurrencies have been performing well while the listed equities in South Africa and most alternative investments have been underperforming (Srilakshmi & Karpagam, 2017). The mean-variance analysis, the Sharpe ratio, the conditional value-at-risk (CVaR) and the mean-variance spanning techniques were employed to analyse the data. The spanning test carried out was the multivariate ordinary least squares (OLS) regression Wald test. The research findings showed that the inclusion of cryptocurrencies in a portfolio of investments improves the efficient frontier of the portfolio of investments and the portfolio of investments risk-adjusted returns. Moreover, the findings suggested that cryptocurrencies are good portfolio diversification assets. However, investments in cryptocurrencies should be made with caution as the risks of investments are high in relation to traditional and alternative investments. The findings of this study advocate for individual and institutional investors to include cryptocurrencies within their South African portfolio of traditional and alternative investments.
