This article examines the susceptibility of cryptocurrencies to coronavirus disease COVID induced panic in comparison with major stock indices. The author employs the Bayesian structural vector autoregression to examine the phenomenon in Bitcoin, Ethereum and Litecoin from 2nd January to 30th June The results suggest that cryptocurrencies returns suffered immensely in the early days of the COVID outbreak following declarations of the disease as a global health emergency and eventually a pandemic in March However, the returns for all three cryptocurrencies recovered by April and remained resistant to further COVID panic shocks. The results further reveal strong predictive power of Bitcoin on prices of other cryptocurrencies. Thus, the author stresses the need for diversification of investment portfolios by including cryptocurrencies given their uniqueness and resistance to shocks during crises.

Crypto traders rejoice! HKCEx’s Bitcoin ATM network takes altcoins

It will also allow users to either login to their HKCEx wallets or to make buying and selling for cash on a no-name basis. A registered user will also be able to top up its HKCEx account with cash, to deal in with no barriers and to withdraw some free funds and either get cash or change them to digital currency. Each ATM will be equipped with all the up-to-date technologies such as QR-scanner, two-factor user identification and chip-based keys. HKCEx has been carried on cooperation with several Chinese banks. However, there was no sign of the ATM to be installed in Mainland. The sprawling growth of Bitcoin market slowed down after relevant Chinese authorities cautioned financial institutions and payment services against the risks of crypto currencies, making clear that Bitcoin is a virtual good rather than legal tender. Following the warning, AliPay and TenPay, two leading domestic third-party payment services, terminated payment and clearing services for crypto-currencies.

Dowd is no evangelist, however; he recognizes the frailties of Bitcoin in its current form, and considers The writer, Kevin Dowd, who teaches economics and finance at Durham University, bases this idea on two foundational assumptions.

In this paper, we explore the volatility spillovers across different Bitcoin markets. We decompose the realized volatility into common and idiosyncratic volatilities, as well as the good and bad volatilities. Then the asymmetry in volatility spillovers between Bitcoin markets is measured by the DY Diebold and Yilmaz index. In addition, we construct statistics to test the asymmetry in volatility spillovers between different Bitcoin markets.

Update - 21st May: HKCex has been the subject of extensive complaints in recent weeks.

Dynamic Network Connectedness of Bitcoin Markets: Evidence from Realized Volatility

Fantazzini, Dean and Zimin, Stephan : A multivariate approach for the simultaneous modelling of market risk and credit risk for cryptocurrencies. Forthcoming in: Journal of Industrial and Business Economics. This paper proposes a set of models which can be used to estimate the market risk for a portfolio of crypto-currencies, and simultaneously to estimate also their credit risk using the Zero Price Probability ZPP model by Fantazzini et al , which is a methodology to compute the probabilities of default using only market prices. For this purpose, both univariate and multivariate models with different specifications are employed. Two special cases of the ZPP with closed-form formulas in case of normally distributed errors are also developed using recent results from barrier option theory.

Cryptocurrency connectedness nexus the COVID-19 pandemic: evidence from time-frequency domains

Cryptocurrencies have received growing attention from individuals, the media, and regulators. However, little is known about the investors whom these financial instruments attract. Using administrative data, we describe the investment behavior of individuals who invest in cryptocurrencies with structured retail products. We find that cryptocurrency investors are active traders who are prone to investment biases and hold risky portfolios. Cryptocurrency investors are more likely to invest in stocks with high media sentiment and more likely to employ heuristics from technical analysis. In line with attention effects and anticipatory utility, we find that the average cryptocurrency investor substantially increases account logins and trading activity after his or her first cryptocurrency purchase. Furthermore, cryptocurrency investors tend to tilt their portfolios toward even more risky securities after cryptocurrency adoption.

The purpose of this study is to investigate volatility connectedness between major cryptocurrencies by the virtue of market capitalization. In this context, this paper implements the frequency connectedness approach of Barunik and Krehlik and to measure short-, medium- and long-term connectedness between realized volatilities of cryptocurrencies. In this study, we examine the volatility connectedness among eight major cryptocurrencies by the virtue of market capitalization by using the frequency connectedness approach over the period July 26, and October 28, To this end, this paper computes short-, medium- and long-cycle overall spillover indexes on different frequency bands.
