Curious About Cryptocurrencies? Investors Need to Make Sure They Separate “Investing” from “Speculation” by Don Mcarthur, CFA®
Curious About Cryptocurrencies? Investors Need to Make Sure They Separate “Investing” from “Speculation” By Don McArthur, CFA® Bitcoin and other cryptocurrencies have received plenty of media coverage lately, and it is natural for investors to wonder about them. Even celebrities have become associated with Bitcoin publicity through social media. Interest has piqued to a point where there are even Exchange Traded Funds (ETFs) that invest in Bitcoin, giving investors the means to invest in the Futures market. After having performed in-depth research on Bitcoin and other cryptocurrencies, our position at Commerce Trust Company is that they should not currently play a role in client portfolios. As part of that research, Commerce Senior Vice President and Investment Analyst Don McArthur, CFA, put together a primer on the topic of cryptocurrencies in general. In the following commentary, he explains why Bitcoin at this stage is more about speculating than investing in something with intrinsic value. He also touches on how Blockchain networking technology not only supports cryptocurrencies, but many other industrial applications as well. We thought you would enjoy this commentary as McArthur shares his thoughts in a mind-opening Q&A. Q . What is Bitcoin and how did it start? A. Bitcoin is one of hundreds of digital currencies, or cryptocurrency, based on Blockchain technology. As an early mover, Bitcoin is by far the largest digital currency. Bitcoin was launched in 2009 by a mysterious person (or persons) known only by the pseudonym Satoshi Nakamoto. Unlike traditional currencies, which are issued by central banks, Bitcoin has no central monetary authority. -

Cryptocurrency: the Economics of Money and Selected Policy Issues
Cryptocurrency: The Economics of Money and Selected Policy Issues Updated April 9, 2020 Congressional Research Service https://crsreports.congress.gov R45427 SUMMARY R45427 Cryptocurrency: The Economics of Money and April 9, 2020 Selected Policy Issues David W. Perkins Cryptocurrencies are digital money in electronic payment systems that generally do not require Specialist in government backing or the involvement of an intermediary, such as a bank. Instead, users of the Macroeconomic Policy system validate payments using certain protocols. Since the 2008 invention of the first cryptocurrency, Bitcoin, cryptocurrencies have proliferated. In recent years, they experienced a rapid increase and subsequent decrease in value. One estimate found that, as of March 2020, there were more than 5,100 different cryptocurrencies worth about $231 billion. Given this rapid growth and volatility, cryptocurrencies have drawn the attention of the public and policymakers. A particularly notable feature of cryptocurrencies is their potential to act as an alternative form of money. Historically, money has either had intrinsic value or derived value from government decree. Using money electronically generally has involved using the private ledgers and systems of at least one trusted intermediary. Cryptocurrencies, by contrast, generally employ user agreement, a network of users, and cryptographic protocols to achieve valid transfers of value. Cryptocurrency users typically use a pseudonymous address to identify each other and a passcode or private key to make changes to a public ledger in order to transfer value between accounts. Other computers in the network validate these transfers. Through this use of blockchain technology, cryptocurrency systems protect their public ledgers of accounts against manipulation, so that users can only send cryptocurrency to which they have access, thus allowing users to make valid transfers without a centralized, trusted intermediary. -
Ideologies of Autonomy
Wikipedia @ 20 Ideologies of Autonomy Christopher M. Cox Published on: Jun 11, 2019 Updated on: Jun 21, 2019 Wikipedia @ 20 Ideologies of Autonomy Introduction When I first began routinely using Wikipedia in the early 2000s, my interest owed as much to the model for online curation the site helped to popularize as it did Wikipedia itself. As a model for leveraging the potential of collective online intelligence, emerging modes of online productivity enabled everyday people to help build Wikipedia and, just as importantly for me, proliferated the use of “Wikis” to centralize and curate content ranging from organizational workflows to repositories for the intricacies of pop culture franchises. As a somewhat obsessive devotee of the television series Lost (2004-2011), I was especially enthusiastic about the latter, since the Lostpedia wiki was an essential part of my engagement with the series’ themes, mysteries, and motifs. On an almost daily basis during the show’s run, I found myself plunging ever deeper into Lostpedia, gleaming reminders of previous plot points and character interactions and using this knowledge to piece together ideas about the series’ sprawling mythology. Steadily, as Wikipedia also became a persistent fixture in my online media diet, I found myself using the site in a similar manner, often going down “Wikipedia holes” wherein I bounced from page to page, topic to topic, probing for knowledge of topics both familiar and obscure. This newfound ability to find, consume, and interact with a universe of ideas previously diffuse among various types of sources and institutions made me feel empowered to more readily self- direct my intellectual interests. -

Creation and Resilience of Decentralized Brands: Bitcoin & the Blockchain Syeda Mariam Humayun A dissertation submitted to the Faculty of Graduate Studies in partial fulfillment of the requirements for the degree of Doctor of Philosophy Graduate Program in Administration Schulich School of Business York University Toronto, Ontario March 2019 © Syeda Mariam Humayun 2019 Abstract: This dissertation is based on a longitudinal ethnographic and netnographic study of the Bitcoin and broader Blockchain community. The data is drawn from 38 in-depth interviews and 200+ informal interviews, plus archival news media sources, netnography, and participant observation conducted in multiple cities: Toronto, Amsterdam, Berlin, Miami, New York, Prague, San Francisco, Cancun, Boston/Cambridge, and Tokyo. Participation at Bitcoin/Blockchain conferences included: Consensus Conference New York, North American Bitcoin Conference, Satoshi Roundtable Cancun, MIT Business of Blockchain, and Scaling Bitcoin Tokyo. The research fieldwork was conducted between 2014-2018. The dissertation is structured as three papers: - “Satoshi is Dead. Long Live Satoshi.” The Curious Case of Bitcoin: This paper focuses on the myth of anonymity and how by remaining anonymous, Satoshi Nakamoto, was able to leave his creation open to widespread adoption. - Tracing the United Nodes of Bitcoin: This paper examines the intersection of religiosity, technology, and money in the Bitcoin community. - Our Brand Is Crisis: Creation and Resilience of Decentralized Brands – Bitcoin & the Blockchain: Drawing on ecological resilience framework as a conceptual metaphor this paper maps how various stabilizing and destabilizing forces in the Bitcoin ecosystem helped in the evolution of a decentralized brand and promulgated more mainstreaming of the Bitcoin brand. ii Dedication: To my younger brother, Umer. -
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. IBM’s Payment Protocol Out of Beta (9/4) Blockchain World Wire, a global blockchain based payments network by IBM, is out of beta, CoinDesk reports. -
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.

BGX Bluepaper MOCK
ABSTRACT V 1.0 2018.03.27 BGX Blue Paper, v 3.0 Breaking Down of the BGX Platform Technology BGX_BLUEPAPER_3.0 0 ABSTRACT V 3.0 2019.01.09 ABSTRACT This document describes the technological understanding of the BGX Platform, the integrative distributed ledger for a new generation of business networks. The first open- source distributed ledger focusing on digital assets, BGX provides a seamless and easy integration between businesses – using decentralization to construct shared economic mini-ecosystems. The core differentiators of the transformative BGX distributed network is the hierar- chal topology of nodes, the ability to exchange digital assets in reloadable transactions, not just currency, the anchoring of the system, its unique API capabilities, and the dual token system. Among particular importance is the F-BFT Consensus that enables the hierarchal topology, as well as unlimited horizontal and vertical scalability of the network’s through- put. The data processed by the network is placed in a special structure of the DAG (Di- rected Acyclic Graph) instead of blocks; it has the ability to grow in several directions simultaneously, unlike a blockchain. The main theses of the presented model: • Commitment to open and decentralized solutions that allow the use of tech- nology for the benefit of society, aimed at safety and free use; • The main technological solutions essentially depend on the business model and the customer value proposition, the technology and architecture should be maximally harmonized with business priorities; • There is no universal panacea for building the architecture of a modern dis- tributed technological system; to build sustainable solutions, it is necessary to find a compromise between scaling, security, decentralization and the cost of the solution; • The blockchain revolution continues, in addition to popular first-generation networks such as Ethereum and Blockchain, advanced solutions such as IOTA, HASHGRAPH / HEDERA and STELLAR appear.
