Bitcoin e cyber self-laundering: lo sguardo sospettoso della Cassazione sull'impiego di criptovaluta
2023
In Judgment n. 27023 of 2022, the italian Supreme Court recognized the confgurability of the crime of self-money laundering in the conduct of a person who uses the proceeds of crimes committed by him to purchase bitcoin, not directly, but through the intermediation of cryptocurrency exchange companies. The Author takes the pronouncement as a starting point to probe the extent to which the culture of suspicion, with which the anti-money laundering legislation is imbued, and the stigmatization of cryptocurrency have influenced the Supreme Court's guidance, in which there emerges a strong temptation to establish a kind of automatism between the input of illicit proceeds into the bitcoin system…
Bitcoin e rivoluzione digitale internazionale. Note a margine di una sentenza della United States District Court of Columbia.

This Note is about the recent recognition, by the United District Court of Columbia, of bitcoin as 'money'. The Note offers a brief insight of the decision and some reflections on the actual international digital revolution and the current threats/opportunities related to it.
A behavioural finance explanation of speculative bubbles: evidence from the bitcoin price development
2019
In 2008 a group of programmers, alias Satoshi Nakamoto, introduced bitcoin. Bitcoin is a cryptocurrency or virtual money derived from mathematical cryptography and is conceived as an alternative to government authorised currency. The founder anticipated, through bitcoin’s construction and his digital mining processes, that bitcoin prices would be relatively stable. However, the recent bitcoin price decline proves that bitcoin is extraordinarily volatile and is not that stable as hoped. Although some scientists have already shown that the fundamental value of bitcoin is zero, the price of bitcoin has reached over 19.000$ in December 2018. Since then, bitcoin prices dropped nearly 70% from th…
Next-Day Bitcoin Price Forecast
2019
This study analyzes forecasts of Bitcoin price using the autoregressive integrated moving average (ARIMA) and neural network autoregression (NNAR) models. Employing the static forecast approach, we forecast next-day Bitcoin price both with and without re-estimation of the forecast model for each step. For cross-validation of forecast results, we consider two different training and test samples. In the first training-sample, NNAR performs better than ARIMA, while ARIMA outperforms NNAR in the second training-sample. Additionally, ARIMA with model re-estimation at each step outperforms NNAR in the two test-sample forecast periods. The Diebold Mariano test confirms the superiority of forecast …

Herding in the cryptocurrency market: CSSD and CSAD approaches
2018
Abstract We analyse the existence of herding in the cryptocurrency market through the cross-sectional standard (absolute) deviation of returns. Our results show that extreme dispersion of returns is explained by rational asset pricing models although it is possible to observe herding during down markets, which highlights the inefficiency and risk of cryptocurrencies. We also observe that the smallest digital currencies are herding with the largest ones, thus traders base their decisions on the performance of the main cryptocurrencies. However, the herding phenomenon cannot be solely attributed to Bitcoin, since the rest of the market is not herding with the main cryptocurrency.
Complexity traits and synchrony of cryptocurrencies price dynamics
2021
AbstractIn this study, we characterized the dynamics and analyzed the degree of synchronization of the time series of daily closing prices and volumes in US$ of three cryptocurrencies, Bitcoin, Ethereum, and Litecoin, over the period September 1,2015–March 31, 2020. Time series were first mapped into a complex network by the horizontal visibility algorithm in order to revel the structure of their temporal characters and dynamics. Then, the synchrony of the time series was investigated to determine the possibility that the cryptocurrencies under study co-bubble simultaneously. Findings reveal similar complex structures for the three virtual currencies in terms of number and internal composit…
Bitcoin in the Scientific Literature – A Bibliometric Study
2019
Abstract Since 2012, there has been growing interest in bitcoin scientific research from different fields, including computer science and engineering, economics, business and finance, law and regulatory. The purpose of this paper is to evaluate bitcoin literature based on the structures and networks of science, as a first step in the research of this new phenomenon. Analysing the growing scientific literature on bitcoin published between 2012 and 2019, we provided useful insights on academic research in this field regarding publication year, type and category, authors, journals and citations. The source of the 887 documents which support the study was Web of Science Core Collection. Using V…
Cryptocurrencies in the Light of Money Definitions
2020
Purpose: The aim of the article is to attempt to assess the phenomenon of digital currencies through the prism of existing money definitions as well as to determine to what extent the existing definitions of money are able to answer the question whether private decentralized digital currencies are money in the traditional sense or are they a completely new phenomenon that cannot be put in the framework of previous definitions of money. Design/methodology/approach: This study provides a critical literature review of the cryptocurrency’s definitions in comparison to traditional money definition. The literature review was intended to determine whether bitcoin could be treated as money. Finding…
