Yayın Threat of intervention in cryptocurrency market: West side story of Bitcoin and Ripple(Bucharest University of Economic Studies, 2023) Aysan, Ahmet Faruk; Isac, Nicoleta; Drammeh, Ousman; Khan, Asad ul Islam; Özcan, Rasim; Yönetim Bilimleri Fakültesi, İktisat BölümüThis study examines the impact of intervention threats on the price and volume volatility of Bitcoin and XRP. Using the Threshold or GJR-GARCH model, we analyse the relationship between news shocks (representing intervention threats) and the volatilities of Bitcoin and XRP price and volume returns, based on data from January 2014 to April 2021. The results indicate a significant association between news shocks and Bitcoin's price volatility, suggesting that intervention-related news events have a notable impact. However, the relationship between news shocks and XRP's price volatility is insignificant. Notably, XRP's volume returns demonstrate a positive and significant relationship with news shocks, while Bitcoin's volume returns do not exhibit a significant relationship. Additionally, past shocks and conditional variance shocks significantly contribute to the volatility of today's price or volume returns. These findings suggest that Ripple (XRP) may benefit from the implicit threat of intervention, strategically managing its availability to control price surges.Yayın Decentralized finance(Springer Nature, 2021) Özcan, Rasim; Yönetim Bilimleri Fakültesi, İşletme BölümüNewer and better ways of financing lubricates the wheels of an economy. In recent years, there have been phenomenal changes in technologies used in finance. One of such technologies was introduced by creating the first cryptocurrency Bitcoin. The technology behind this invention is known as blockchain. Although there are and there might be other use cases of blockchain technology, the finance era is important and currently it is the most adapted industry; currently there are a number of cryptocurrencies, tokens, smart contract applications among others. This article seeks to introduce the basics of—so called—decentralized finance (DeFi) through an exploration of blockchain technology in the field of finance. The focus is on the definition of decentralized finance, its elements, its current state and its future. Elimination of intermediary need, easier access, improved inclusiveness, and transaction speed, flexibility to write any contract that can be codable, immutability of transactions, better interoperability and censorship resistance are some of the main advantages of blockchain. Additionally, increased privacy, transparency, enhanced security, efficiency in the form of reduction in overhead costs for banks, and trust are considered as the benefits of blockchain technology in finance, hence for DeFi. Its power need due to the excessive computer power needs, setting standards in validating new blocks and in communicating between different networks are important issues. Besides, user experience, scalability, current speed of blockchain networks, regulations like AML and KYC requirements, the lack of regulation in DeFi, and interoperability are key issues as well. In summary, the current state of DeFi markets is not technologically able to provide a worldwide service at the scale the centralized finance provides. It needs improvements in its technology and sound regulations to gain wide acceptance.
