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.

The number of cryptocurrencies has increased from about 2,000, with a market capitalization of over $200 billion in late 2017, to over 8,000, with a market capitalization of about $1.6 trillion. For context, the market capitalization of global equities is about $110 trillion, that of the S&P 500 stocks is $35 trillion and that of US Treasuries is $22 trillion. Reported trading volume in cryptocurrencies, as represented by the two largest cryptocurrencies by market capitalization, has increased sixfold, from an estimated $6.8 billion per day in late 2017 to $48.6 billion per day in May 2021.1 This data is based on what is called “clean data” from Coin Metrics; the total reported trading volume is significantly higher, but much of it is artificially inflated.2,3 For context, trading volume on US equity exchanges doubled over the same period. -
Bitcoin Tumbles As Miners Face Crackdown - the Buttonwood Tree Bitcoin Tumbles As Miners Face Crackdown
6/8/2021 Bitcoin Tumbles as Miners Face Crackdown - The Buttonwood Tree Bitcoin Tumbles as Miners Face Crackdown By Haley Cafarella - June 1, 2021 Bitcoin tumbles as Crypto miners face crackdown from China. Cryptocurrency miners, including HashCow and BTC.TOP, have halted all or part of their China operations. This comes after Beijing intensified a crackdown on bitcoin mining and trading. Beijing intends to hammer digital currencies amid heightened global regulatory scrutiny. This marks the first time China’s cabinet has targeted virtual currency mining, which is a sizable business in the world’s second-biggest economy. Some estimates say China accounts for as much as 70 percent of the world’s crypto supply. Cryptocurrency exchange Huobi suspended both crypto-mining and some trading services to new clients from China. The plan is that China will instead focus on overseas businesses. BTC.TOP, a crypto mining pool, also announced the suspension of its China business citing regulatory risks. On top of that, crypto miner HashCow said it would halt buying new bitcoin mining rigs. Crypto miners use specially-designed computer equipment, or rigs, to verify virtual coin transactions. READ MORE: Sustainable Mineral Exploration Powers Electric Vehicle Revolution This process produces newly minted crypto currencies like bitcoin. “Crypto mining consumes a lot of energy, which runs counter to China’s carbon neutrality goals,” said Chen Jiahe, chief investment officer of Beijing-based family office Novem Arcae Technologies. Additionally, he said this is part of China’s goal of curbing speculative crypto trading. As result, bitcoin has taken a beating in the stock market. -

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. -

GLOBAL LEGAL STUD. 335, 337-38 (2014) (describing how Bitcoin is a virtual currency). 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. -
Is Bitcoin Really Untethered?
THE JOURNAL OF FINANCE • VOL. LXXV, NO. 4 • AUGUST 2020 Is Bitcoin Really Untethered? JOHN M. GRIFFIN and AMIN SHAMS∗ ABSTRACT This paper investigates whether Tether, a digital currency pegged to the U.S. dollar, influenced Bitcoin and other cryptocurrency prices during the 2017 boom. Using al- gorithms to analyze blockchain data, we find that purchases with Tether are timed following market downturns and result in sizable increases in Bitcoin prices. The flow is attributable to one entity, clusters below round prices, induces asymmetric auto- correlations in Bitcoin, and suggests insufficient Tether reserves before month-ends. Rather than demand from cash investors, these patterns are most consistent with the supply-based hypothesis of unbacked digital money inflating cryptocurrency prices. INNOVATION, EXCESSIVE SPECULATION, AND DUBIOUS behavior are often closely linked. Periods of extreme price increases followed by implosion, commonly known as “bubbles,” are often associated with legitimate inventions, technolo- gies, or opportunities. However, they can be carried to excess. In particu- lar, financial bubbles often coincide with the belief that a rapid gain can be ∗John M.

Coinbase Explores Crypto ETF (9/6) Coinbase Spoke to Asset Manager Blackrock About Creating a Crypto ETF, Business Insider Reports
Crypto Week in Review (9/1-9/7) Goldman Sachs CFO Denies Crypto Strategy Shift (9/6) GS CFO Marty Chavez addressed claims from an unsubstantiated report earlier this week that the firm may be delaying previous plans to open a crypto trading desk, calling the report “fake news”. Coinbase Explores Crypto ETF (9/6) Coinbase spoke to asset manager BlackRock about creating a crypto ETF, Business Insider reports. While the current status of the discussions is unclear, BlackRock is said to have “no interest in being a crypto fund issuer,” and SEC approval in the near term remains uncertain. Looking ahead, the Wednesday confirmation of Trump nominee Elad Roisman has the potential to tip the scales towards a more favorable cryptoasset approach. Twitter CEO Comments on Blockchain (9/5) Twitter CEO Jack Dorsey, speaking in a congressional hearing, indicated that blockchain technology could prove useful for “distributed trust and distributed enforcement.” The platform, given its struggles with how best to address fraud, harassment, and other misuse, could be a prime testing ground for decentralized identity solutions. Ripio Facilitates Peer-to-Peer Loans (9/5) Ripio began to facilitate blockchain powered peer-to-peer loans, available to wallet users in Argentina, Mexico, and Brazil. The loans, which utilize the Ripple Credit Network (RCN) token, are funded in RCN and dispensed to users in fiat through a network of local partners. Since all details of the loan and payments are recorded on the Ethereum blockchain, the solution could contribute to wider access to credit for the unbanked.
