亲,给「白话区块链」加个“星标”

熊大熊二来了,光头强你的信仰还在么?(下)

上周,我们从区块链自身角度、历史角度、资金角度、交易角度,梳理了区块链的现状

今天,我们将从宏观角度、行业角度、操作角度和学习角度,来看看区块链以及投资者的未来。


 01 
宏观角度

如果你关注了一些财经自媒体公众号,或是一些金融达人的微博,你应该会经常看到类似的一句话“2019,现金为王”

就现状而言,宏观层面确实不怎么乐观:

美股,尤其是以高科技股为首的纳斯达克,从10月份起一路向下;

传说中只涨不跌的一线城市房价,2018年跌掉了20%-30%,而且此类情况不仅限于中国;

传说中只涨不跌的腾讯,2018年跌去了接近一半的市值;

本周大宗商品也未能幸免,原油、螺纹钢等都在暴跌……

总而言之,就是:资产变得不值钱了。这里提到的“资产”,同样也包括比特币。

那么从宏观层面,近两个月有哪些可以关注的事件?

▪G20
宏观层面,最重要的事件应该就是这两天举办的G20峰会,此次峰会达成的某些经济共识,或将极大影响未来金融资本的走势。中美在贸易关系上能否达成共识,短期内将对全球各类投资市场产生较大影响。

Bakkt
2018年11月21日,被视为年内加密货币市场最大希望的Bakkt宣布,其上线时间由今年12月12日延期至2019年1月24日,市场当时也很应景地予以暴跌回应。

Bakkt的目标,是通过比特币实物结算期货,将比特币打造成新一代主流金融产品。大家一直期待传统资金入场,若能够有合法的大规模渠道,Bakkt有望成为第一个带领大量资金入场的选手。所以,不难理解Bakkt延期对于市场的打击。

ETF
最近几年行情一旦有异动,就会被寄予厚望的ETF,就像是个“磨人的小妖精”,每次给了你希望,却又不会直接答应你。

据Coindesk 11月28日报道,美国证券交易委员会(SEC)主席Jay Clayton周二(当地时间11月27日)表示,在解决市场操控问题之前,不会批准加密货币ETF【参考文章:比特币的达摩克利斯之“锤”——ETF(上)比特币的达摩克利斯之“锤”——ETF(下)】。

这真是让业内人望穿秋水。但圈内对于“SEC批准加密货币ETF”这件事还是很有信心的,或许只是时间问题。


 02 
行业角度

V神去年曾“保守地”预言,有90%的爱西欧项目都会归零。

当时很多人并不在意,将该预言当成耳旁风。现在回看,V神还当真是“保守了”。

若现在有人跟你说99%的项目会归零,你信不?

去翻初创企业的成功率,其实数据惨不忍睹。只是去年的“疯牛”行情,让大家选择性无视,将这些数据变成“房间里的大象”。

从上世纪80年代开始,国外就有很多相关研究:在100万家初创公司中,只有6家能最终走到IPO;初创公司第一年的死亡率高达90%,其他一般公司的死亡率为27%;初创公司第一年的失败率为40%,十年内的失败率为90%;50%的小企业会在2年内倒闭,80%的小企业会在5年内倒闭。

我们凭什么认为区块链公司,会有所不同?但就目前的数据而言,也不用那么悲观。

一方面,很多大公司开始布局区块链,包括中国的B-ATJ公司(点击标蓝字母,可参看对应的大厂布局故事)

另一方面,越来越多的资源和人才开始进入区块链行业,尤其是那些原先对区块链及加密货币持怀疑态度的科技金融精英。

关于这一点,某加密货币投资人在推特表示:“当你发现不同行业的聪明人都不约而同去投身某一行业,追随聪明的人的脚步是最笨且最有效的投资方式。当然,首先你要学会区分聪明的投机者 VS 聪明的创业者。”

 03 
操作角度

“股神”巴菲特,曾在2008年跟一个知名对冲基金的合伙人打过一个赌,压注100万美金,赌约10年。赌的什么?巴菲特赌对冲基金无法战胜标普500指数。那个对冲基金合伙人,精心挑选了五只对冲基金,跟巴菲特支持的标普500硬刚。

今年,赌局结束了,在过去的十年里,标普500指数平均年复合收益率7.1%,那精选的5只对冲基金的平均年复合收益率是2.2%。

区块链投资有“标普500”么?如果有的话,或许会是比特币。

一些数字货币投资者,在复盘时发现一个现象:入市后,经过一通操作,无论是赔是赚,貌似都没最初入市时全仓比特币保持不动所获收益高。

正如前段时间流行的那个段子:“一通操作猛如虎,比特只剩0.5。”

不知道你现在对于投资策略,是否有更深刻的见解。需要强调的就是:任何投资决策应该都是你自己深思熟虑的结果。

 04 
学习角度

当前,有一个很奇怪的现象:有些人可以轻易拿出毕生积蓄投资一个自己不熟悉的领域和行业。

区块链投资,是个比股市门槛更高的行业,你最好能懂点儿计算机、经济、政治等各类知识。

从金融角度来看,区块链投资,与股市等传统交易市场并无区别,依旧是“一赚二平七亏”,依旧接近“二八定律”。

有意思的是:大多数人都知道这个定律,却依然在不怎么知情的情况下匆匆入局。唯一能够解释这个现象的,除了贪婪,或许是那个著名的“乌比冈湖效应”(人们总是容易高估自己的实际水平,换句话说,就是“自我拉抬偏差”

现实生活中,充斥着这类现象。比如,据类似的统计实验显示,90%的人认为自己的驾车技术高于平均水平。

市场是残酷的,只有20%的人在赚钱,80%的人其实都在赔钱。

你要做的,或许是抛开自己的“迷之自信”,努力学习,提高认知,争取成为那20%的人。熊市,或许是最佳的学习机会。“投资的本质是认知的变现,你很难赚到看不见的钱!”


 05 
小结

比特币在过去10年,曾经被宣告过300多次“死亡”。最近,开始有声音宣告“区块链”的死亡。或许,这不是第一次,也不会是最后一次。其实,区块链还没有结束,它才刚刚开始。

现在,你还会憧憬区块链的未来吗?快来留言分享吧。

EOS’ Dan Larimer Is Eyeing Another Cryptocurrency Project

Daniel Larimer, a developer at Block.one, the company that created EOS, has shared plans for the development of another cryptocurrency project, shortly after EOS itself launched.

The plans were recently announced via

Telegram

:

“I will say it again, I am not leaving EOSIO or B1. In the process of working on EOSIO security and scalability I stumbled upon a new set of tradeoffs for a potential crypto token and I have merely been exploring whether there is a market for those tradeoffs. EOSIO is the future of blockchain and each day our team at block one is making it faster, more secure, more scalable, and more flexible.”

It seems that, during the process of

EOS’

development, Larimer came across a new set of concepts. He ended up not applying these new concepts on EOS and now seemingly wants to use them to create a new token:

“The hypothetical token would be immutable, non-programmable, and limited to a currency role. It would in no way compromise the much larger uses for EOSIO applications.”

Other attributes of the new token were revealed on a separate

Telegram

group. In it, he stated that “crypto people will hate it,” and called the new token “MonerEOS,” potentially indicating that it will be a match-up between privacy-centric cryptocurrency the monero (XMR) and EOS.

Crypto Community Reactions

It seems that Larimer was not far off as the messages were not well received by the crypto community, as it is evident by comments on

Reddit

. Regardless of Larimer reassuring investors that the new project would not compromise the development of EOS, many in the community are still skeptic about the developer’s intentions.

EOS is considered an “ICO unikorn”, having received over $4 billion in funding in its year-long ICO. However, almost 5 months after EOS’ mainnet launch, Larimer is drawing criticism for already setting his sights on another project.

Larimer is credited as the creator of EOS, Steem, and BitShares, all blockchains with a high transaction output. With this new announcement, the entrepreneur is becoming known for jumping from project to project. While many see no fault in it, the situation may be especially concerning if we take into account the recent downfalls of Larimier’s previous projects.

As reported by

CryptoGlobe

, the blockchain social media platform Steemit has recently had to cut more than 70% of its staff due to the cryptocurrency bear market. According to the firm’s CEO Ned Scott, the firm is now undergoing restructuring efforts to be able to stay afloat.


New findings

claim that EOS is not a blockchain, as transactions are not cryptographically validated. As if that wasn’t enough, EOS moderators are able to change transaction history and revert previously-confirmed transactions. Larimer himself as

said

that decentralization is not EOS’ top priority.

UAE Government Launch National Blockchain Technology and Artificial Intelligence Initiatives

At the Second United Arab Emirates (UAE)  Government Annual Meeting held in Abu Dhabi, the region’s authorities launched two national platforms targeted at reinforcing the UAE’s artificial intelligence (AI) and blockchain technology ecosystems and ultimately make the state a hotbed for new technologies, reported the Emirates News Agency on November 28, 2018.

UAE Aiming for the Top

Distributed ledger technology (DLT) has shown in recent times that it has groundbreaking potentials to revolutionize a vast array of industries and the Government of the United Arab Emirates, like several other forward-thinking nations are making serious efforts to be at the frontline of the blockchain movement.  

At the Second UAE Government Annual Meeting held on 28 November 2018, by the AI and Blockchain Joint Working Group, officials created two initiatives that would see to the development of blockchain technology and AI in the state.

Participants brainstormed on the best possible ways to attract foreign investment, encourage entrepreneurship and put in place an enabling environment for DLT and other new technologies to thrive.

The stakeholders also talked about the challenges hampering the adoption of AI and DLT, how to overcome the obstacles and carry out public enlightenment campaigns concerning the importance of nascent technologies.

Two Key Programs Launched

With several jurisdictions across the globe formulating robust regulatory frameworks for their blockchain technology ecosystems, the UAE is also doing its best to be a force to reckon with in the world of blockchain technology.

The meeting saw the launch of both the AI and Blockchain Guide Initiative as well as the National Programme for AI and Blockchain Capacity Building.

According to the officials, the AI and Blockchain Guide Initiative will focus on providing a standardized definition of AI and DLT at the federal level and also make relevant government parastatals aware of the usefulness of the burgeoning technologies.

The National Programme for AI and Blockchain Capacity Building, on the other hand, is targeted at creating educational courses and scholarships in AI and blockchain technology, providing short training programmes to Emirati staff and more.

“The UAE is poised to adopt AI and blockchain technologies in several sectors of the economy including health, educational, finance and other industries,” said Minister of State for Artificial Intelligence, Omar bin Sultan Al Olama.

Importantly, organizers of the programmes have also hinted they would carry out extensive surveys to determine the jobs that are most impacted by AI and New technologies and reduce the number of employees in those sectors, while also training the replaced workers to fit into other areas of the economy.

Unlike China that has embraced only blockchain technology, relegating cryptocurrency and ICOs to the bin, the UAE has a liberal stance towards cryptos.

Earlier in October, BTCManager informed the UAE Commodities Authority had approved ICOs in its bid to transform the nation’s capital markets.

Thai SEC Explains Two Laws Could Apply to Crypto Securities

Thailand’s Securities and Exchange Commission (SEC) has reportedly clarified how existing laws can apply to crypto securities. In addition, Thai companies planning to issue securities tokens abroad would be guilty of wrongdoing under the Digital Asset Act for avoiding regulated fundraising channels.

Applicable Current Laws

Thai SEC Explains Two Laws Could Apply to Crypto SecuritiesOn Thursday, the Bangkok Post reported that Tipsuda Thavaramara, deputy secretary of the Thai SEC, revealed that “the regulator will have to consider how to deal with STOs [securities token offerings] for issues such as share ownership, voting rights, and dividends.”

Thailand enacted cryptocurrency regulation in May. The country’s Digital Asset Act regulates cryptocurrencies and initial coin offerings (ICOs) and installs the Thai SEC as the main regulator of the crypto industry. However, STOs are not included within the scope of any current laws.

The publication detailed:

If STOs have conditions similar to other fund-raising securities, they could undergo processes similar to those for IPOs, thus coming under the SEC Act … STO trading could fall under the Digital Asset Act if fund-raising is carried out in the same manner as for ICOs.

Thavaramara clarified, “At the moment, we have not decided whether STOs fall under the SEC Act or the Digital Asset Act,” adding that “it depends on the STO’s conditions and the details in its white paper.” She emphasized, “The SEC will have to consider carefully how to respond to each STO.”

Thai Company Plans STO Launch in the US

Thai cryptocurrency exchange operator Satang Corp. has announced a plan to launch its own STO in the U.S., the Bangkok Post also reported.

Thai SEC Explains Two Laws Could Apply to Crypto SecuritiesSatang Corp. operates a crypto exchange in Thailand called Satang Pro, formerly Tdax. The exchange has been granted temporary approval to operate in Thailand while its full application is being reviewed by the Thai SEC.

Thai SEC Explains Two Laws Could Apply to Crypto SecuritiesThe company “recently said it would issue an STO in the first quarter of next year but file for fund-raising with the US’s SEC and list on the T-zero exchange in the US,” the news outlet wrote on Thursday.

Overstock.com’s August filing with the U.S. SEC states that its Tzero platform aims to provide “current market participants the opportunity to access crypto-securities without having to incur switching costs.” The filing further describes, “Tzero represents a regulated bridge between the traditional securities markets and the fast-emerging world of crypto-securities.”

According to the Bangkok Post, Thavaramara explained:

An STO affiliated with Thai investors launching in an international market at this point would be guilty of wrongdoing under the Digital Asset Act. A company making such an STO launch would be trying to avoid regulated fund-raising channels, such as sales of ordinary shares or sales of digital assets via IPO portals.

什么是加密钱包?最全各种类型加密钱包优缺点对比

比特币是一种数字货币。因此,获取和储存货币的方法与传统的法定货币有很大的不同。从技术上讲,比特币不存在任何物理形态或形式,算不上传统意义上的“存钱”。相反,需要存储的是用于访问你的比特币地址的私钥。这就是比特币钱包发挥作用的地方。哪款比特币钱包最好?如何阅读钱包介绍?

什么是比特币钱包?

比特币钱包是一种存储比特币私钥的软件程序。通常,钱包有硬件和软件两种,前者被称为硬件钱包。一般来说,它们允许您访问你的比特币地址,通常使用Bitcoin Core和互联网连接,从而可以进行买卖比特币。

获取区块链钱包是必要的,以便保存任何类型的加密资产或数字货币。虽然某些解决方案只允许你拥有一种数字货币,但绝大多数比特币钱包(许多利用Bitcoin Core开源编程)也允许用户同时持有多种加密货币,包括以太坊(ETH),比特币现金(BCH),Monero(XMR),Ripple(XRP),Stellar(XLM)等。

什么是私钥?

私钥代表允许花费比特币的数字和字母的秘密序列。每个比特币钱包至少包含一个,有时甚至更多的私钥。密钥保存在钱包文件中,并且在数学上与为钱包生成的所有比特币地址相关。

简而言之,这就是你的“门票”,你可以用它来消费比特币。因此,最重要的是你要保证它的安全。这就是所有大型加密货币交易所在存储数字资产时强调高级隐私的原因。

不同类型的比特币钱包

钱包有很多种类型:桌面钱包、移动钱包、纸张钱包、网络钱包和硬件钱包。这些都有不同的特点,允许储蓄管理或退休计划等等。好的钱包评价将使这些功能更加清晰。

桌面钱包,顾名思义,安装在电脑桌面上。这些类型的钱包提供了对软件钱包的完全控制。用户能够生成买卖比特币的比特币地址。当然,它们也允许用户存储私钥。

另一方面,移动钱包提供了更多的便利,因为它们不是固定在一个地方。通常以付费应用的形式出现,可以在智能手机上运行。然而,就功能而言,移动钱包也允许做与桌面钱包相同的事情。一个显著的优势是,移动钱包可以让你在实体店接收支付,通过扫描二维码直接进行支付。实体店接受数字货币。

在各种类型的钱包中:移动钱包、比特币钱包等是纸质钱包。这只是公钥和私钥打印在一起。从技术上讲,纸质钱包是一种冷钱包,因为它是完全离线的,打印出来就是一个纸钱包。

也可以根据钱包使用的操作系统进行区分。因此,您可以拥有Android钱包(即Android应用程序)、iPhone和iPad上的iOS应用程序、Windows、Mac和Linux等。许多软件解决方案都是免费下载的程序。当然,几乎所有热门钱包都可以被归类为Android钱包,因为它们通常是由操作系统支持的,而且它们也有指定的Android应用程序。一些钱包也与挖矿硬件兼容。

热钱包VS冷钱包

下一个区别是基于钱包是否连接到互联网。如果它们连接在一起,就被称为网络钱包,或者最常见的是热钱包。如果它没有连接,并且完全离线运行,那么解决方案称为硬件钱包或冷钱包。

冷钱包通常被认为更安全,只是因为它们不能被网上的人篡改。不联网,因此,他们是安全的任何类型的黑客诈骗和攻击。这是一种离线存储。

另一方面,热钱包是一种基于网络的钱包,它实际上是在互联网上。换句话说,为了访问管理你的比特币,你需要有一个稳定的互联网连接。它们提供了更多的灵活性,其中许多还提供了集成解决方案,方便了数字货币的买卖。但与此同时,它们被认为不那么安全,因为连接到互联网,可能会受到黑客攻击。

当然,这两种解决方案都有各自的优点和缺点。在正确选择存储比特币的钱包提供商时,了解它们至关重要。

热钱包的优点和缺点

与任何钱包提供商一样,热门钱包也有其优缺点。了解这些优点和缺点将使您能够根据自己的特定喜好做出正确的选择。

使用热钱包的好处:

大多数热门钱包是对初学者友好且易于使用。

只要联网,就可以在任何给定时刻提供对你的加密资产的即时访问。

它们通常具有多层安全功能和备份选项。

它们与大多数操作系统兼容,如Windows、Mac和Linux、Android以及挖矿硬件。

提高安全性的双重身份验证。

使用热钱包的缺点:

与冷钱包相比,安全功能更低,因为始终是连接到互联网上。

它们在中心化服务器上运行,因此通常在可以处理的交易数量方面受到限制,这可能会导致偶尔的延迟。

值得注意的是,热钱包对用户非常友好,因此,对于对于希望安全安全地存储加密货币或交易少量加密货币的初学者来说特别方便。但是,如果您想批量存储加密货币,最好还是带一个冷钱包。

冷钱包的优点和缺点

“冷钱包”为那些希望自己的私钥能够安全离线存储的用户提供离线存储解决方案。为了访问离线存储上面的信息,只需要插入计算机即可。这是主要特点,也表现出了一定的优缺点。

使用冷钱包的好处:

除了钱包的主人以外,没有人能访问到保存在里面的信息。

它们不连接互联网,因此提供了更大的安全性。

对于长期投资者来说,这些产品非常适合,他们希望自己的资产能够安全地离线存储。

使用冷钱包的缺点:

“冷钱包”工作起来更有挑战性,而且在处理交易时灵活性有限

它们中的许多不接受所有类型的数字货币

它们可能有点贵

与挖矿软件兼容性很差

如何选择钱包?

当然,如果你想参与买卖加密货币,而且在个人财务的完整性方面也足够合理,你就需要尽可能选择最好的比特币钱包——更不用说为你的交易提供最安全的钱包了。

如果你不确定你想要使用的类型的解决方案,你能做的最好的事情之一,就是阅读比特币钱包评价,调查Bitcoin Core,各种应用程序等等。不用说,选择最好的比特币钱包需要你来决定是否要积极交易或简单地存储你的比特币或任何其他数字货币更长一段时间。

【区势早报】加密货币市场仍缺乏保障措施;全球主流媒体更倾向报道比特币负面消息

数字货币早班车

截至目前,BTC全球均价 4036.00 美元,24小时跌幅 5.69 %;EOS全球均价 2.91 美元,24小时跌幅 3.95 %;ETH全球均价 114.00 美元,24小时跌幅 3.18 %。市值排名前百币种中,24小时涨幅榜前五的是:FREE 24小时涨幅 2133.94 %、THETA 24小时涨幅 68.73 %、BTF 24小时涨幅 12.94 %、SBTC 24小时涨幅 9.28 %、VNS 24小时涨幅 8.09 %。据统计,全球数字货币已超过 2800 种,TOP100总市值为 1,394.02亿美元。

V神:下一波加密货币应用不会建立在炒作之上

据ambcrypto消息,V神在接受采访时谈到了加密货币领域的发展。他还谈到了2019年加密货币领域的下一波大浪潮。对于自今年年初以来,市场上大多数主流加密货币的价值已缩水逾一半,V神认为,该空间目前需要更多的技术“实际应用”来推动它向前发展,整个团队长期以来一直在努力构建该技术。他说:“就像下一波加密货币应用浪潮不会建立在炒作的基础上,因为炒作基本上已经到来了,下一波必须来自真正有用的应用程序且要为人们提供价值的东西。

加密采矿比世界上几乎所有其他大型工业都更环保

据Market Watch消息,加密货币投资公司CoinShares发布的一份报告认为,对加密采矿造成全球能耗的看法是被大大夸大了。事实上,77.6%的比特币采矿使用可再生能源,使其“比世界上几乎所有其他大型工业都更环保”。报告称,“就环境而言,加密采矿虽然代价高昂,其影响微乎其微,而且在可预见的未来也不大可能造成极大危害。

Coinbase已向合格用户提供PayPal提现服务

据ambcrypto报道,虽然Coinbase尚未在其网站上或通过其社交媒体正式宣布,但确实已向合格用户发送电子邮件,允许用户免费将法币提现到其PayPal账户。免费取款目前仅适用于少数几个地区,如美国、英国、欧盟和加拿大。为了启用此选项,用户必须验证他们的身份,然后将收到确认的电子邮件。此外,这也可能意味着PayPal的存款选项正在进行中。此前,曾有推特及Reddit网友报料称Coinbase已开始支持此项服务。

卡巴斯基:加密劫持与当地加密货币法律状态无相关性

据btcmanager报道,根据卡巴斯基实验室旗下网络威胁研究机构Securelist的报告,数字货币的立法控制与加密劫持几乎没有相关性。例如在越南和阿尔及利亚,加密货币几乎是被完全禁止的。但令人惊讶的是,这两个国家出现在挖矿攻击数量排名的前10位,分别占据第三(13.00%)和第六位(9.03%)。另一方面,美国用户受到加密货币劫持攻击的影响最小(1.33%),其次是瑞士(1.56%)和英国(1.66%)用户。

SEC主席:加密货币市场仍缺乏保障措施

据cointelegraph报道,美国证券交易委员会(SEC)主席Jay Clayton11月29日在接受采访时重申了他对加密市场的谨慎看法。Clayton表示,SEC一直在努力教育投资者,让他们了解参与新兴和不可预测市场存在的风险,加密货币市场的监管仍在形成中。SEC试图说明,虽然交易加密货币看起来与在纳斯达克或纽交所进行交易一样,但加密市场还不具备与这些市场相同的保障措施。SEC已经在试图阻止那些传统市场的操纵方面努力工作了70年。主席还承认,SEC在离岸代币销售方面面临局限,他试图明确表示,如果投资者在海外购买数字资产并且出现问题,那么SEC很少能够将其作为一个实际问题来解决。

全球主流媒体更倾向报道比特币负面消息

据bitcoinexchangeguide报道,区块链市场研究公司Clover对2013年1月1日至2018年7月31日期间全球48家主流媒体发布的7527篇加密货币相关文章进行了一项研究。研究结果显示,在2016年,积极的文章在数量和强度方面远远超过负面文章。然而,随着2017年中期报道激增,表达负面情绪的文章越来越普遍。这种趋势的部分原因是沃伦·巴菲特和马克·库班等人预测加密货币市场的“泡沫”正在进行中。该研究指出,随着比特币在2017年最后几天市值暴跌,负面文章成倍增加,警示文章很常见。迎合年轻受众的媒体如“福布斯”和“商业内幕”,其报道的积极情绪一直高于总体中位数,合计1335篇文章相对积极。CNBC在调查的时间段内发表了近1000篇关于加密货币的文章,其中52.9%为正面,47%为负面。尽管许多媒体最近几个月出现了越来越多的怀疑文章,但随着岁月的流逝,一些出版物实际上变得更加乐观。值得注意的是,福布斯和CNET已转向积极。

VanEck再次与SEC会面讨论比特币ETF

据coindesk报道,本周早些时候,VanEck,SolidX和CBOE的成员与美国证券交易委员会(SEC)公司财务部、交易和市场部以及总法律顾问办公室会面,就比特币市场已为ETF做好准备提出了新的论据。与此前的会面不同,此次会面举例说明了已经拥有ETF的资产,包括原油、白银和黄金。演示文稿特别将期货市场的概念与现货市场联系起来,并指出对于金银等货币替代品而言,两者之间的这种联系可以用经验证据证明。此外,这种类型的价格协整“是运作良好的资本市场的证据”。这些公司继续解释称,与商品期货相似,比特币的现货和期货价格紧密相连,再次提供了“运作良好的资本市场的证据”。另一方面,他们认为比起已支持ETF的其他商品,比特币生态系统“不易受操纵”。此前,VanEck等已于10月9日会见SEC新上任的专员Elad Roisman,讨论有关比特币ETF的规则变更提案。

白俄罗斯高科技园区发布加密货币“完整法规”

据cointelegraph报道,根据11月30日发布的文件,白俄罗斯高科技园区(HTP)已经制定了该国加密货币市场的运营规则。HTP是一个为IT业务做出贡献的国家经济特区,通常被称为白俄罗斯硅谷,负责制定加密货币行业在该国的监管规则。今天,HTP已经发布了五个文件,分别为“申请人的要求”,“加密平台运营商的要求”,“加密货币交易所运营商的要求”,“1CO运营商的要求”和“内部控制规则的要求”。据白俄罗斯当地新闻媒体Dev.by报道,目前这些规则已被接受,它们组成了“完整的白俄罗斯加密货币法律规定”。

Bitcoin Difficulty Dropping as Bitcoin Price Forces Miners Offline

/latest/2018/12/bitcoin-difficulty-dropping-as-bitcoin-price-forces-miners-offline/

In line with the trend that started in October, Bitcoin’s mining difficulty is projected to drop lower for the third adjustment in a row, showing the sharply dropping hashrate as miners go offline. As of press time, a -13% adjustment is expected to occur within 2.9 days for the first time since 2011, according to data gathered by bitcoinwisdom.com.

Bitcoin’s hashing difficulty algorithm, which adjusts on average every two weeks (2016 blocks) is designed to maintain ten-minute block times. The difficulty dropping is a reflection of hashing power on the network also dropping.

It is historically very rare that the Bitcoin difficulty drops, because it’s rare that the hashrate drops for a sustained period, however, falling prices have forced many miners offline lowering the hashrate. For example, over the past year difficulty has fallen during only about 17% of the adjustment events, while overall hashrate increased nearly fourfold during the period from January to October.

CryptoGlobe recently reported on the relationship between bitcoin’s price on one hand, and the Bitcoin network’s hashing difficulty on the other. Some experts have observed that six to twelve months of falling and flat changes in hashrate and difficulty has historically presaged an end to negative price action – in this case, we would be anticipating an end to the 2018 bear market.

Why Is hashrate and Difficulty Falling?

The fairly straightforward answer to this question is that: bitcoin’s price is falling. A falling price in bitcoin means a falling reward for miners when they mine a block. Mining could eventually become unprofitable for miners, especially less efficient ones. In that case, firms could either continue mining at a loss – if they are able – anticipating higher prices in future, or close down, an example of which CryptoGlobe recently reported on.

With bitcoin’s price recently breaking the key $6,000 support level to as low as $3,500, augmenting the pain of an already brutal ten-month decline in cryptoasset prices, it is not surprising to see hashrate on the network falling, especially after such a sustained uptrend.

Enter Bitcoin Cash

With respect to hashrate, difficulty, and the price of bitcoin, the recently introduced elephant in the room is the Bitcoin Cash forking conflict.

One of the main characters behind the hardfork, Craig Wright (with whom CryptoGlobe recently conducted an exclusive interview), vowed to his erstwhile partner Roger Ver to mobilize all the resources necessary to emerge as the dominant side of the split – although the conflict now seems to have ended in an unceremonious fizzle.

Both sides have historically mined bitcoin as well as Bitcoin Cash, and it is likely that both sides re-deployed some of their hashrate to mine their side of the Bitcoin Cash fork. In addition, they could have sold bitcoin in order to fund their operations, as this is precisely what Wright threatened to do in a tweet.

What Does this Mean?

Whatever the causes, the upshot of falling hashing difficulty is that pain on the bitcoin mining network will eventually, inevitably be eased.

Element Group have speculated that in situations of continuously falling difficulty, sell pressure will eventually be eased, as more efficient miners (or at any rate, miners willing and able to outlast the hard times) “are compelled to sell less bitcoin to cover their fiat-denominated expenses thereby reducing the natural selling pressure by miners. This reduction in natural mining pressure may cause the price to rise, which could lead to miners needing to sell even less bitcoin – this creates a virtuous cycle and is the seed from which a new bubble forms.”

Austrian Blockchain Center for Multidisciplinary Research Established in Vienna

The COMET Centers, which are coordinated by the Austrian Research Promotion Agency (FFG), have approved the Austrian Blockchain Center (ABC) in Vienna, according to a Nov. 29 press release.

ABC involves 21 scientific institutions, 54 companies, 17 associated participants, and 16 international institutions and companies. According to the release, the research center will be multidisciplinary and focus on Internet of Things (IoT), finance, energy, logistics, and applications in public administration.

Alfred Taudes, academic director and coordinator of the center, and head of the Research Institute for Cryptoeconomics at WU Vienna University of Economics and Business, said that a multidisciplinary approach is “necessary for comprehensive research.”

The center will conduct research and development in five different areas; cryptography technology and security; cryptoeconomic modelling and blockchain applications for business; emerging industries and blockchains in manufacturing; data science methods for blockchain analytics and predictions; and legal and political implications.

The new research center will purportedly work in tandem with other COMET Centers and international blockchain initiatives. The centers are funded by the Austrian Ministry for Transport, Innovation and Technology, and the Federal Ministry for Digital and Economic Affairs. ABC will also receiving support from the provinces of Lower Austria and Vorarlberg.

The Austrian government has been proactive in its support for blockchain initiatives and development of the technology. In September, the government set to offer a $1.35 billion bond on the Ethereum blockchain. At the time, Austria’s Finance Minister, Hartwig Loeger, said that the ministry is considering blockchain tech as it forms a “focus on economic policy.”

Earlier this month, the Austrian government supported a U.K. cancer research company that uses blockchain in its work. Lancor Scientific, which has developed a device to detect multiple types of cancer, records screening results with smart contracts on a blockchain. The firm plans to open a research laboratory in the Austrian city of Graz.
