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. -

Importantly, identifying which social media behaviors are more prevalent for sexual LGBQ minorities helps understand online behavioral differences and promote psychological well-being. Social media Method: Participants were recruited online (N = 1294) indicating use of Facebook or Twitter. They completed Downward social comparisons validated psychosocial questionnaires and responded to questions regarding specific social media behaviors. Univariate comparisons assessed differences in social media behaviors between the sexual minority group (n = 178) and the heterosexual group (n = 1116). A stepwise binary logistic regression model identified the specific social media behaviors that were most associated with the sexual minority group. Results: The univariate comparisons identified many differences in social media behavior between the sexual minority and heterosexual groups. Based on the multivariate analyses, the key social media behaviors most associated with the sexual minority group included more hours on Twitter and a higher likelihood of downward social comparisons. Conclusion: Due to the pervasiveness of social media, potentially negative impacts associated with the social media behaviors of sexual minorities should be further examined. -

With quarantine measures in place, and in the absence of travel and party photos on social media, do individuals feel they are missing out on enjoyable experiences? The current work shows that FOMO has not disappeared during the pandemic, even when socially distancing at home, but has been replaced by feelings towards new online activities (e.g., online concerts, virtual gatherings). As a consequence, we find that FOMO threatens well-being by causing important psychological and health issues, such as sleep deprivation, loss of focus, declined productivity, and finding relief in knowing that others have difficulty keeping Citation: Hayran, C.; Anik, L. up with abundant digital content.

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.

Investigating Consumer's Fear of Missing out And
INVESTIGATING CONSUMER’S FEAR OF MISSING OUT AND SOCIAL MEDIA FATIGUE: AN EXTENDED LITERATURE REVIEW By SHUOYAN WANG A dissertation submitted to Auckland University of Technology in partial fulfilment for the degree of Master of Business (Marketing) September 2020 Faculty of Business, Economics and Law Department of Marketing Primary Supervisor :Associate Professor Mark Glynn ABSTRACT The information age has brought about the emergence of many digital tools. One of the tools is social media network sites, such as Facebook, Twitter, and Instagram, that have increasingly gained popularity worldwide. A large percentage of the global population is actively engaged in social media activities which have changed people’s way of life. Businesses also have to adapt to this change by being actively involved in social media. To take advantage of social media opportunities many consumer increase their social media activity which results in Fear Of Missing Out (FOMO). Meanwhile, another phenomenon is social media fatigue, which refers to the feeling of being overwhelmed by social media usage. Although the two phenomena have been closely examined as separate topics, the relationship between FOMO and social media fatigue has not been properly addressed. This study fills in this research gap and strives to understand the relationship between consumers’ FOMO and consumer social media fatigue and adopted the extended literature review methodology. From the findings, it is clear that FOMO can result in social media fatigue. Particularly, three variables are discovered to be mediators of this relationship, which are information overload, anxiety, and depression. Clear evidence indicates that FOMO can lead to information overload which will cause social media fatigue. -

Chason William & Mary Law School, [email protected] Repository Citation Chason, Eric D., "How Bitcoin Functions As Property Law" (2019). Faculty Publications. 1896. https://scholarship.law.wm.edu/facpubs/1896 Copyright c 2019 by the authors. This article is brought to you by the William & Mary Law School Scholarship Repository. https://scholarship.law.wm.edu/facpubs How Bitcoin Functions As Property Law Eric D. Chason* Bitcoin replicates many of the formal aspects of real estate transactions. Bitcoin transactions have features that closely resemble grantor names, grantee names, legal descriptions, and signatures found in real property deeds. While these “Bitcoin deeds” may be interesting, they are not profound. Bitcoin goes beyond creating simple digital deeds, however, and replicates important institutional aspects of real estate transactions, in particular recordation and title assurance. Deeds to real property are recorded in a central repository (e.g., the public records office), which the parties (and the public) can search to determine title. When one grantor executes more than one deed covering the same property, recordation acts (race, notice, and race-notice) determine which grantee wins. The Bitcoin blockchain replicates the public records office, giving anyone with a computer the ability to see any Bitcoin transaction. Bitcoin mining replicates the recording of deeds, a process by which formally valid transactions between two parties become essentially a public record. When one grantor executes more than one transaction covering the same Bitcoin, a miner determines which grantee wins simply by moving one transaction to the blockchain before the others. -

Bitcoin is a new decentralized payment network that started operating in January 2009. This new technology was created by a pseudonymous author, or group of authors, called Satoshi Nakamoto in an article that was publically released [1] in the cypherpunk mailing list. The cypherpunks are anarchists and cryptographers that who have been concerned with personal privacy in the Internet since the 90’s.
