  • Virtual Currencies and Terrorist Financing : Assessing the Risks And
    DIRECTORATE GENERAL FOR INTERNAL POLICIES POLICY DEPARTMENT FOR CITIZENS' RIGHTS AND CONSTITUTIONAL AFFAIRS COUNTER-TERRORISM Virtual currencies and terrorist financing: assessing the risks and evaluating responses STUDY Abstract This study, commissioned by the European Parliament’s Policy Department for Citizens’ Rights and Constitutional Affairs at the request of the TERR Committee, explores the terrorist financing (TF) risks of virtual currencies (VCs), including cryptocurrencies such as Bitcoin. It describes the features of VCs that present TF risks, and reviews the open source literature on terrorist use of virtual currencies to understand the current state and likely future manifestation of the risk. It then reviews the regulatory and law enforcement response in the EU and beyond, assessing the effectiveness of measures taken to date. Finally, it provides recommendations for EU policymakers and other relevant stakeholders for ensuring the TF risks of VCs are adequately mitigated.

Government bonds and cash-based securities alike are currently the most important parts of a well- functioning collateral market. However, in that, there is a growing weakness as rehypothecation creates a systemic risk in the financial system as a whole. The increasing reuse of collateral makes these assets far from risk-free and shows the potential instability of the financial markets and that it is more fragile than many would like to admit. Bitcoin could become an important part of the solution and challenge the dominating collateral assets in the future.

Bitcoin is supported by a distributed network of users and relies on advanced cryptography techniques to ensure its stability and reliability. A Bitcoin is simply a chain of digital signatures (i.e., a string of numbers) saved in a “wallet” file. This chain of signa- tures contains the necessary history of the specific Bitcoin so that the system may verify its legitimacy and transfer its ownership from one user to another upon request. A user's wallet consists of the Bitcoins it contains, a public key, and a private key.

  • 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.

  • Segwit2x –
    SegWit2x – A New Statement The Overwhelming power of SegWit2x In order to safeguard the community from an undesired chain split, the upgrade should be overwhelming, but it’s not enough. It should also ‘appear’ as overwhelming. People, businesses and services needs to be certain about what is going to happen and the risks if they won’t follow. My impression is that still too many speaking english people in the western world think the upgrade will be abandoned before or immediately after block 494784 is mined, thus they are going to simply ignore it. That could lead to unprepared patch up and confusion, while naïve users risk to harm themselves. For this reason and for the sake of the Bitcoin community as a whole, we need to show again, clearly and publicly the extent of the support to SegWit2x. We also need to commit ourselves in a widespread communication campaign. I know this is not a strict technical matter, but it could help a lot avoiding technical issues in the future. What we have to do First, we need a new statement from the original NYA signers and all the business, firms and individuals who joined the cause later. That statement should be slightly different from the original NYA though, and I am explaining why. We all know that what Bitcoin is will be ultimately determined by market forces, comprehensive of all the stakeholders involved: businesses, miners, users, developers, traders, investors, holders etc. Each category has its own weight in the process, and everybody has incentives in following the market.

  • Trading and Arbitrage in Cryptocurrency Markets
    Trading and Arbitrage in Cryptocurrency Markets Igor Makarov1 and Antoinette Schoar∗2 1London School of Economics 2MIT Sloan, NBER, CEPR December 15, 2018 ABSTRACT We study the efficiency, price formation and segmentation of cryptocurrency markets. We document large, recurrent arbitrage opportunities in cryptocurrency prices relative to fiat currencies across exchanges, which often persist for weeks. Price deviations are much larger across than within countries, and smaller between cryptocurrencies. Price deviations across countries co-move and open up in times of large appreciations of the Bitcoin. Countries that on average have a higher premium over the US Bitcoin price also see a bigger widening of arbitrage deviations in times of large appreciations of the Bitcoin. Finally, we decompose signed volume on each exchange into a common and an idiosyncratic component. We show that the common component explains up to 85% of Bitcoin returns and that the idiosyncratic components play an important role in explaining the size of the arbitrage spreads between exchanges. ∗Igor Makarov: Houghton Street, London WC2A 2AE, UK.
