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.

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. -

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. -

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.

A View from Mining Pools
1 Measurement and Analysis of the Bitcoin Networks: A View from Mining Pools Canhui Wang, Graduate Student Member, IEEE, Xiaowen Chu, Senior Member, IEEE, and Qin Yang, Senior Member, IEEE Abstract—Bitcoin network, with the market value of $68 billion as of January 2019, has received much attention from both industry and the academy. Mining pools, the main components of the Bitcoin network, dominate the computing resources and play essential roles in network security and performance aspects. Although many existing measurements of the Bitcoin network are available, little is known about the details of mining pool behaviors (e.g., empty blocks, mining revenue and transaction collection strategies) and their effects on the Bitcoin end users (e.g., transaction fees, transaction delay and transaction acceptance rate). This paper aims to fill this gap with a systematic study of mining pools. We traced over 1.56 hundred thousand blocks (including about 257 million historical transactions) from February 2016 to January 2019 and collected over 120.25 million unconfirmed transactions from March 2018 to January 2019. Then we conducted a board range of measurements on the pool evolutions, labeled transactions (blocks) as well as real-time network traffics, and discovered new interesting observations and features. Specifically, our measurements show the following. 1) A few mining pools entities continuously control most of the computing resources of the Bitcoin network. 2) Mining pools are caught in a prisoner’s dilemma where mining pools compete to increase their computing resources even though the unit profit of the computing resource decreases. 3) Mining pools are stuck in a Malthusian trap where there is a stage at which the Bitcoin incentives are inadequate for feeding the exponential growth of the computing resources. -
Mining Pool Selection Under Block Withholding Attack †
applied sciences Article Mining Pool Selection under Block WithHolding Attack † Kentaro Fujita, Yuanyu Zhang * , Masahiro Sasabe and Shoji Kasahara Graduate School of Science and Technology, Nara Institute of Science and Technology, Takayama-cho, Ikoma, Nara 630-0192, Japan; [email protected] (K.F.); [email protected] (M.S.); [email protected] (S.K.) * Correspondence: [email protected] † This paper is an extended version of our paper presented in the 2020 IEEE International Conference on Blockchain (IEEE Blockchain 2020). Abstract: In current Proof-of-Work (PoW) blockchain systems, miners usually form mining pools to compete with other pools/miners in the mining competition. Forming pools can give miners steady revenues but will introduce two critical issues. One is mining pool selection, where miners select the pools to join in order to maximize their revenues. The other is a Block WithHolding (BWH) attack, where pools can inject part of their hash/mining power into other pools to obtain additional revenues without contributing to the mining process of the attacked pools. Reasoning that the BWH attack will have significant impacts on the pool selection, we therefore investigate the mining pool selection issue in the presence of a BWH attack in this paper. In particular, we model the pool selection process of miners as an evolutionary game and find the Evolutionarily Stable States (ESSs) of the game (i.e., stable pool population states) as the solutions. Previous studies investigated this problem from the perspective of pool managers and neglected the revenues from attacked pools (attacking revenues), leading to less accurate and insightful findings.
