年赚13亿美元的Coinbase为何还要融资?Coinbase副总裁:送上门的你不要?

通过最新一轮融资,Coinbase已经由加密货币交易所变身为硅谷独角兽公司。Coinbase正在积累“战争资金”,以备“不时之需”。

至少,Coinbase负责企业和业务开发的副总裁Emilie Choi是这样描述这次E轮融资的。Coinbase本周宣布获得由Tiger Global Management领投,Polychain等参投的3亿美元融资,其中Polychain是由Coinbase前雇员Olaf Carlson-Wee领导的公司。

Choi本周三表示,“这是摆在面前的机会,我们其实并不需要融资。”

在谈到为什么一家据说每年产生13亿美元利润的公司还要从风险投资者那里获取资金时,她补充说:

“我们想要钱以备不时之需,这样能够抓住任何我们认为非常重要的机会。”

换句话说,Choi看到的主要机会来自于Coinbase平台增加对新资产的支持,最终会有“数千”种潜在的加密货币登上Coinbase。

除了Coinbase最近开始支持的由Circle公司发行的稳定币USDC之外,Coinbase还正在另一种与法定货币挂钩的数字资产。

“随着平台增加更多数字资产,稳定币属于自然的延伸范围。随着我们进入加密货币的实用阶段,我们意识到阻止用户真正使用加密货币的一个重要因素是它的波动性。因此,稳定币有助于为加密货币的使用和稳定铺平道路。

她补充称,随着Coinbase增加对更多资产的支持,稳定币或隐私币等多种类别自然会出现在Coinbase平台。该公司已经在考虑添加以隐私为中心的资产zcash。

当被问及是否有一天Coinbase会上线ICO代币来时,Choi回答说,该公司不想“关闭”未来任何机会的大门。

她说:

“目前所有的优先事项都集中在增加支持资产、扩大国际路线等方面。”

Autonomous Partners的创始人兼董事总经理、加密货币老兵阿里安娜•辛普森(Arianna Simpson)表示,Coinbase此次融资不同寻常,但并不令人意外。

Simpson向CoinDesk表示:

“通常情况下,如果某一家公司进行如此大规模融资,原因可能是因为它们没有盈利。不过(Coinbase)看到了在有利条件下筹集资金的机会,于是他们抓住了这个机会。”

不止3亿美元

Coinbase还没有公布这次E轮融资的确切规模;第二批投资者仍在等待一些文书工作的完成。

Choi表示,“这次本次融资初选名单的第一部分,我们还保留了一些进行第二批投资的投资者名额。不过,这(3亿美元)将是这轮融资的主要部分。”

总部位于柏林的基金1kx的联合创始人、风险投资家Lasse Clausen向CoinDesk表示,此次募资尤其令人印象深刻,因为据报道,过去两个季度,Coinbase的活跃用户大幅减少。总体而言,研究公司Diar发现,自去年以来,Coinbase的美元交易量下降了80%。

Clausen说,

“自2017年12月以来,Coinbase的收入和活跃用户一直在下降,因此,投资者仍在进行如此大规模的投资,这一事实表明了他们对加密货币的中长期看好程度。”

这也是Choi所说的为什么Coinbase现在融资以及为“长期”准备。她说,这些收益还将有助于为国际扩张提供资金。

Choi表示,

“当然,英国一直是我们关注的焦点。我们可能会在更广泛的欧盟有更多的扩张和扩展。我们非常看好日本,认为它是我们真正想进入的第一个亚洲市场。”

实际上,Coinbase正在伦敦和东京的新办事处招聘几个职位。因此,Choi表示,这次E轮融资将帮助公司提供有竞争力的就业机会。此外,这轮融资使得该公司的估值达到了创纪录的80亿美元。

在谈到Coinbase最终目标是IPO时,Choi补充说:

“无论何时,只要我们准备好成为一家上市公司,我们都会这么做。”

Brazil’s Tax Authority Goes After Cryptocurrency Profits

Brazil’s tax authority has published proposals to regulate the cryptocurrency landscape over concerns digital assets are being used to launder money and evade tax. A document released by the Department of Federal Revenue of Brasil (RFB) disclosed plans that will force cryptocurrency traders to reveal their identities and for exchanges to submit financial reports to the authority each month.

  Draft Tax Guidelines Compel Exchanges to Furnish RFB With Monthly Financial Reports

Brazil’s Tax Authority Goes After Cryptocurrency Profits

In proposals released earlier this week, the RFB stated that all digital currency exchanges in Brazil are now required to provide monthly updates of financial performance, including personal information of dealers. The ancillary obligations are for tax compliance purposes and also to prevent alleged money laundering, the regulator said. RFB indicated that this will help bring transparency and confidence to a sector that in the last five years has seen explosive growth – so big that the number of cryptocurrency investors has eclipsed that of those trading in common stocks on Brazil’s Sao Paulo-based B3 Stock Exchange.

The draft means that traders would no longer be able to operate anonymously. Until now, anybody buying and selling bitcoin and other digital currencies have been able to do so anonymously, allegedly making it attractive to criminals and tax dodgers, the authority claims.

According to the RFB, Brazilian residents and companies that transact more than 10,000 reals (about $2,700) on foreign cryptocurrency exchanges per month are required to report this information. Individuals who fail to comply by delaying tax declarations face a fine of $400 while a three-percent fee on the transaction value will be levied against those who lie about their income or provide insufficient information.

Brazil’s Cryptocurrency Industry Sees Rapid Growth

The value of cryptocurrency traded on exchanges in the Latin American country has swelled from just $12.1 million in 2014 to $2.24 billion at the end of last year, as investors piled into an industry which thrives on anonymity and less regulation. The Department of Federal Revenue of Brasil has guided trade volumes to reach between $4.86 billion and $12.15 billion this year.

Brazil’s Tax Authority Goes After Cryptocurrency Profits

“The numbers, and their annual growth, demonstrate the relevance of the cryptocurrency market in Brazil, especially for the tax administration, since these transactions are subject to income tax on capital gains,” the RFB detailed. “The search for anonymity, which is one of the main attractions for the use of certain cryptocurrencies, must always be fought, including by the tax authority.”

The tax collector is accepting public input to the draft guidelines between now and Nov. 19. The proposals come in the wake of a recent court ruling which compelled Banco do Brasil and Banco Santander to reopen the bank accounts of cryptocurrency exchange Bitcoin Max that were closed in September without explanation. The two banks have since reactivated the accounts to avoid paying fines of between $1,350 and $5,400.

What do you think about the cryptocurrency proposals in Brazil. Let us know in the comments section below.

Rapper T.I. Sued For $5 Million Over Alleged Involvement In Cryptocurrency Scam

Rapper T.I. Sued For $5 Million Over Alleged Involvement In Cryptocurrency Scam

Rapper T.I. has recently been sued by a group of investors over his alleged involvement in a cryptocurrency scam.


According to reports, T.I. and a businessman claimed a token they sold would go up in value, and engaged in a “pump and dump” scheme to help it.

Rapper T.I. and businessman Ryan Felton have recently found themselves on the end of a lawsuit concerning a large-scale cryptocurrency scam that allegedly swindled investors out of $2 million.

According to Complex, the duo announced a FLiK Token back in August 2017 with a range of promises. Felton allegedly claimed tokes could be purchased at six cents each, but would be worth $14.99 within 15 months.

The lawsuit alleges the rapper and businessman engaged in a “pump and dump” scheme to drive up the token price from six to 21 cents. But the price later crashed after tokens were dumped. Currently, one FLiK token is worth $0.0009.

False Impressions

Those who invested into the project were allegedly told by Felton the stark price drop could be attributed to T.I.’s family and friends, who sold gifted tokens “…on coinexchange.com causing rapid devaluation.”

The lawsuit also claims Felton crafted a new company and said it bought FLiL, while denying that he had anything to do with it. Investors are now seeking at least $5 million in damages and are accusing T.I. and Felton of securities fraud. They say more than $2 million was lost.

The suit also alleges the two fraudulently gave the appearance that Kevin Hart was going to be the face of the token. According to TMZ, Hart is not being sued.

Celebrities And Crypto

Controversy surrounding celebrity involvement in the cryptocurrency world isn’t new. CryptoGlobe recently reported on another case, where famous boxer Floyd Mayweather and music producer DJ Khaled are allegedly being sued for involvement in the Centra Tech cryptocurrency scam.

Both Mayweather and Khaled have been named in a lawsuit for purportedly being celebrity endorsers of Centra Tech, as they promoted it across various social media platforms.

However, it is not immediately clear if the two have been recently indicted due to the existence of new information, or were associated with a previous class action lawsuit filed in June. The report from TMZ says investors in Centra Tech are looking to get their money back, along with damages, from the company and the two celebrities.

如何在浏览器中使用VPN来保护自己的隐私







大部分的浏览器都可以通过添加扩展程序使用VPN服务,有些浏览器是内置这些功能。这些工具让我们能以一种简单实惠的方式保护自己的隐私并享受无审查的浏览体验。

用加密货币购买谷歌浏览器的VPN扩展程序

现在要想保护自己的上网有隐私以及绕开某些地区或国家的限制,几乎都要用到V*PN。有很多提供V*PN服务的供应商,其中有很多都接受加密货币。浏览器支持扩展程序或整合有这些功能让我们获得免审查和基本上无法追踪的上网体验变得更加容易。

shutterstock_611472605-696x361

谷歌浏览器的用户有很多选择,而加密货币的爱好者应该会对其中的一些感兴趣。V*PN Mentor推荐了几shutterstock_1098133325-300x200个扩展程序,这些扩展程序都乐于接受加密货币支付。Private Internet Access就是其中一个。这个应用可以直接从谷歌商店里下载。安装并注册后,就可以选择一个订阅计划。购买两年的价格是每月2.91美元并且接受加密货币支付。

Express VPN是另外一个较受欢迎的应用。但是,如果要使用谷歌浏览器的扩展程序,用户需要先安装一个桌面应用。用户还需要在VPN的网站使用电子邮件进行注册,然后选择订阅服务的时间和支付方式,刚开始他们每月只需要8美元多一点。这款应用可以使用BTC支付。Nord V*PN是较为简单的一款应用,可以隐藏IP地址,但使用的加密技术与VPN的不同。它也可以在谷歌商店里下载。订阅三年的价格是每个月2.99美元。

在大多数情况下,安装VPN扩展程序后你就可以在浏览器地址栏的右边看到它的图标。使用下拉菜单,可以更改设置并选择自己偏好定位。有些VPN支持其他的安全功能,可防范恶意软件和屏蔽广告。

火狐测试付费的VPN功能

上述的VPN也可以在火狐浏览器上使用,火狐也支持各种各样的实用又免费的扩展应用。不过,开发火狐的软件公司目前正在测试一项新功能,使用更好的加密技术为用户的更好的隐私保护,每月的费用是10美元。火狐最近与瑞士公司Proton VPN合作,整合付费的订阅服务,提供更高等级的安全性。

shutterstock_635558900-696x464

此外,Proton VPN的服务器位于瑞士、瑞典和冰岛,这些地方的法律禁止政府获取存储信息。该公司还称,不会记录用户任何的使用记录。火狐在一篇公告中透露,将从10月24日开始为一部分美国的火狐用户提供这项实验功能。这项服务兼容Windows、Mac、Linux、iOS和Android系统。该公司指出,推出这项功能是为了增加收入来源。

Opera提供免费的VPN功能

Opera,另外一个颇受欢迎的浏览器,已经先一步整合免费的VPN功能。这项功能可以通过地址栏左侧专门的一个按钮激活,同时可以通过设置进行自定义。无限的数据流量,并且可以切换不同的国家:欧洲、美国、亚洲,或者选择自动。虽然可以选择仅在默认浏览器上使用VPN,但是激活这项功能后,网速可能会稍微变得有点慢。不管怎样,Opera VPN还是一个很实用的自带功能,不需要花钱也不需要订阅。

The Daily: SEC Ramps Up Enforcement, 60% of Smart Contracts Are Dormant

In Saturday’s edition of The Daily, we take a look at the SEC’s annual report, which reveals where cryptocurrencies sit on their radar. We also consider the fate of dormant smart contracts, 60% of which have never seen use according to a new report. All that plus the reaction to Coinbase’s latest token listing, which hasn’t pleased everyone.

Also read: ‘Decentralized’ Exchange IDEX to Introduce Full KYC

SEC Zeroes in on Cryptocurrency Scams

The U.S. Securities and Exchange Commission (SEC) has released its annual report and the 45-page document has plenty to say about cryptocurrency. Initial coin offerings (ICOs) are referenced more than 30 times in the report, which notes: “In the past year, the Division has opened dozens of investigations involving ICOs and digital assets, many of which were ongoing at the close of FY [financial year] 2018.” The report also explains that the SEC isn’t just looking at ICOs, but at other potential scams being perpetrated within the cryptocurrency space. It finishes:

The Division also has recommended that the Commission use its trading suspension authority to prevent investors from being harmed by possible scams … the Commission suspended trading in the stock of over a dozen publicly traded issuers because of questions concerning, among other things, the accuracy of assertions regarding their investments in ICOs and operation of cryptocurrency platforms.

The SEC’s report surfaced just as it emerged that another celebratory is facing a lawsuit over their promotion of a dubious ICO. Clifford Joseph Harris Jr., better known as T.I., is being charged over his involvement with “flik token,” which investors were promised would increase by 25,000 percent. It didn’t.

60% of Smart Contracts Have Never Been Used

The Daily: SEC Ramps Up Enforcement, 60% of Smart Contracts Are DormantResearchers at Northeastern University and the University of Maryland have pored over the code governing Ethereum smart contracts and emerged with some interesting findings. Of the 1.2 million smart contracts they examined, the vast majority were clones or extremely similar to one another. As a result, they found there to be less than 6,000 unique smart contract “clusters.”

The danger with such widespread usage of code, as the researchers pointed out, is that vulnerabilities are likely to spread far and wide throughout the ecosystem. There is one saving grace, however, that might limit the fallout from a widespread bug: around 60% of all Ethereum smart contracts have never been interacted with. These “ghost contracts” remain dormant, deprived of users willing to spend the gas required to trigger them.

New Coinbase Listing – Brave or Foolish?

On Nov. 2, Coinbase Pro announced that the latest token to be added to its exchange would be BAT, the advertising rewards-based currency used within the Brave browser. While the news was hailed in some quarters, not least among BAT bagholders, not everyone was impressed. “Welp, it’s official,” tweeted Dan Elitzer. “Coinbase’s lawyers are comfortable with listing digital Chuck-E-Cheese tokens. The Howey Test is clearly out the window.” Jackson Palmer, meanwhile picked holes in Brave’s integration of BAT, and suggested the browser would operate more effectively without the token:

Distribution territories: $10, $12, $14.

Accumulation territories: $4, $3, $2.

EOS is still seeing its price move within a range this week. There been various indecisive movements in the cryptocurrency’s chart. It has been trading along with the two SMAs, which are currently next to each other. The cryptocurrency saw its price decline towards the $4 territory on August 14.

EOS, EOSUSD, Cryptocompare chartEOS Chart by TradingView

EOS’ SMAs are next to each other, below the $6 territory. The Stochastic Oscillators moved past range 40 and are pointing north. This means the cryptocurrency is currently trying hard to get past its SMAs.

If the $5 territory is breach, EOS could see its price enter a freefall, which would see it retest its August low of $4. On the other hand, a break through the $6 mark could see the bulls go through a number of distribution territories.

HTC Exodus Phones Preparing to Ship in December (With More Questions Than Answers)

HTC Exodus Phones Preparing to Ship in December With More Questions Than Answers News

HTC Exodus Phones Preparing to Ship in December (With More Questions Than Answers)


Pre-orders of purchased HTC Exodus phones are set to ship in December. HTC is hyping the technology as a viable tool for the blockchain and cryptocurrency community, but many are still skeptical.


Taiwanese firm HTC Corporation made headlines back in May after announcing plans for the first native blockchain smartphone, dubbed the HTC Exodus.

In October, HTC made the phone available for pre-order with the expectation the first units would ship in December.

Payment was only possible in Bitcoin (BTC) 00 or Ethereum. The company said the phone would be available in 34 countries.

HTC has hyped up the phone by touting the “secure enclave” portion of the device.

The goal of the locked portion is to keep user’s cryptocurrency wallet keys safe, a solution the company hopes is a middle-ground between cold-storage and software wallets. The Exodus will also support underlying protocols like Lightning and Dfinity.

Despite HTC’s intention to craft a device to woo the cryptocurrency and blockchain community, many are still wary about trusting the smartphone.

Others think the phone’s inevitably small market, especially since pre-sales are only carried out with cryptocurrency, is setting it up to fail.

A Ploy To Capture a Niche Market?  

The Exodus has received a lot of attention for its cryptocurrency capabilities, but the phone boasts a number of other impressive specs, according to Wired.

The outlet wrote how the phone has a 6in Quad HD+ display, a Snapdragon 845 processor, dual cameras, and a IP68 waterproof rating. The phone runs  Android Oreo and has 6GB of RAM with 128GB of storage.

A look at the website for the HTC Exodus shows a variety of quotes from well-known cryptocurrency figures who have praised the device. Phil Chen of HTC said more than 30 industry leaders advised the phone’s development team at “critical touch points,” according to Wired.

Some speculate the creation of the device is part of a strategy by HTC to push off competition from industry giants like Apple and Samsung.

Not Everyone Is Convinced

Some people, like Lawrence Lundy at Outlier Ventures, see the HTC Exodus as an interesting idea with innovations that represent a move forward.

However, Lundy believes people with big cryptocurrency holdings are still going to use cold-storage wallets, or will opt for a phone like the Finney smartphone from Sirin Labs.

The Problems with Data Storage

Others remain generally skeptical about trusting a phone manufacturer with keeping cryptocurrency safe, especially since everyday investors have a variety of software wallets to choose from.

Speaking to these points, Chen argued, according to Wired, the Exodus safe enclave is “almost on a par with cold storage.” He also said API would be released so people can build and enhance Exodus hardware.

Research : Most Ethereum-based Smart Contracts Are Using Potentially Vulnerable Code

/latest/2018/11/most-ethereum-based-smart-contracts-are-using-potentially-vulnerable-code/

Research : Most Ethereum-based Smart Contracts Are Using Potentially Vulnerable Code

Researchers at the University of Maryland and the Northeastern University recently analyzed Ethereum-based smart contracts to determine “how users and contracts interact with one another.”

The collaborative research effort involved making modifications to Ethereum’s Geth client in order to retrieve bytecodes from all contracts issued on the Ethereum blockchain. Bytecodes are “compact numeric codes, constants, and references” that can be “efficiently executed.”

Using Bytecodes To Analyze Smart Contracts

According to TheBlock, the information obtained from the bytecodes “covered nearly three years worth of blocks” and it came from the “first five million blocks” produced and logged on the Ethereum network.

After carefully examining the bytecodes, the researchers found that the majority, 60%, of all the smart contracts issued on Ethereum had “never been interacted with.” This indicates that there may be a large amount of dormant (or unused) code and crypto tokens on Ethereum’s mainnet.

Moreover, the data from the bytecodes revealed “an extremely high level of code reuse and code similarity on Ethereum.” In fact, the researchers were able to reduce the 1.2 million smart contracts created on Ethereum to 5,877 contract ‘clusters’ as they contain “highly-similar bytecodes.”

Reusing Bad, Insecure Code

Although reusing code is a very common practice as there are templates for routine procedures, the “high-level of code reuse” (in this case) suggests that potential bugs or security vulnerabilities found in certain contracts could also affect “thousands of similar contracts that have reused their code.”

The researchers noted that in 2017, the number of transactions on Ethereum increased significantly from about 40,000 per day to over 1 million every 24 hours. Importantly, the Ethereum network is still processing a large number of transactions despite the drop in price of its native token, ether (ETH).

At present, the transaction failure rate on Ethereum is about 0.01%-0.1% and about one-third of all smart contracts are only executed by other contracts – instead of being initiated by users.

Serious Vulnerabilties, Common Misconception

As CryptoGlobe reported in June, a smart contract bug on the ICON (ICX) network allowed anyone, except the contract’s owner, to suspend transactions on the cryptocurrency platform’s blockchain.

Although the software glitch was fixed later on, users on social media criticized ICON’s developers for not being more careful. At the time, the market capitalization of the platform’s native token, ICX, was around $800 million.

Notably, there is a common misconception that smart contracts are able to reduce transaction costs and eliminate intermediaries, or third-parties. As explained by Bitcoin developer, Jimmy Song, “the execution of the agreed-to consequences are what make smart contracts powerful, not in the contract’s innate intelligence.”

Song added that smart contracts were being written mostly by people who were not lawyers, or qualified legal experts. These “newbies” usually do not understand how to write proper contracts – which can potentially lead to vulnerabilities, or flaws, in their construction.
