South Korea Allows Cryptocurrency Trading for Real-Name Registered Accounts

South Korea Allows Cryptocurrency Trading for Real-Name Registered Accounts



Six Korean banks will begin allowing the simultaneous opening of accounts, deposits and withdrawals, as well as transfers of funds between these accounts and exchanges, beginning on January 30, 2018, but with some new restrictions.

South Korea’s government continues its efforts to rein in the trading of virtual currencies such as ether and bitcoin with a new announcement from South Korea’s Financial Services Commission. Investors will now be required to convert their virtual bank accounts to real-name bank accounts in order to continue trading. Deposits and withdrawals are allowed only between real-name bank accounts and matching crypto-exchange accounts within the same bank. The “real name” registration system for cryptocurrency trading will begin by January 30, 2018, with six banks, which include Nonghyup Bank and Shinhan Bank.

Koreans have found cryptocurrencies to be an attractive high-yield investment option; it is estimated that South Korea accounts for 20 percent of bitcoin trades worldwide. The Korean government has been trying to restrict crypto-trading recently, raiding major exchanges and floating ideas such as bans on domestic trading. A statement from the Office for Government Policy Coordination reflected an increased level of frustration with speculative investing in cryptocurrencies: “[We] can’t let this abnormal situation of speculation go on any longer.”

The South Korean government also said this week that it is planning to collect corporate and income taxes at a collective rate of 24.2 percent from local cryptocurrency exchanges this year.

Today’s announcement is also seen as a method to curb money laundering and fraud in addition to providing what should be a simpler and more acceptable (to the government) method of trading crypto in South Korea.

EdgeSecure’s Paul Puey: “Digital Security Will Take Place on the Edges”

EdgeSecure CEO Paul Puey: “Digital Security Will Take Place on the Edges”



Security is one of the hottest topics in today’s ever-evolving digital world. A steady flow of debate continues to take place at tech forums worldwide on topics like encryption, passwords, two-factor authentication, hardware wallets and the like.

As cryptocurrencies and the tools being used to manage them take shape, questions loom about the most efficacious ways to protect both user assets and privacy. One individual who is at the epicenter of this active space is Paul Puey. He is co-founder and CEO of EdgeSecure, a blockchain-inspired, decentralized, open-source, zero-knowledge, global information security solution platform.

Airbitz, his signature enterprise was birthed in 2013 as a bitcoin wallet provider and merchant directory. Today, he’s orchestrating a rebrand of this wallet, now called EdgeSecure.

In an interview with Bitcoin Magazine, Puey talks about the tricky balance between new security and privacy measures being introduced and user experience. He also explores an emerging theme called “securing the edges” that forms the basis of his current work

BM: What sort of problems are you attempting to solve these days?

PP: The aspect of cryptocurrency we initially wanted to address revolved around how to effectively use secure keys. That was the impetus behind our decision to build a feature rich, functionally rich wallet at Airbitz over the years. We feel like this has really differentiated us in the whole area of key management.

BM: How does your concept of EdgeSecure fit in here?

PP: Our goal has been to broaden Airbitz by turning our key management standard into a platform for other apps. Even before we rebranded, we were already using the term Edge Security to examine how to come up with a solution that’s different from enterprise security. We view our approach as fundamentally different in the sense that we’re not trying to make a router or server more secure. Rather, our aim is to take data and secure it before it ever hits a device.

In short, we are able to secure data before it goes out onto a network or server. People and their devices are what we are trying to secure. That’s where the term Edge comes from — before a user’s data ends up on their device, goes out to a network, goes onto a server — the encryption of that data happens first, as we say, “on the edges.”

BM: But what about server networks?

PP: We still believe that server security is important. But the visibility and encryption of that data all happens first before the data gets saved, broadcast and sent out on the network or gets onto a server. The concept of making data private and secure to the point where only the user can access it “on the edges” has never been an area of focus for cybersecurity companies.

BM: So, in a nutshell, how does all of this actually work?

PP: It works through a combination of technologies we’ve had for decades but have never been packaged the way we are seeking to. The technology that we’ve developed involves encrypting data on the client side. Most of the software out there doesn’t do this. Rattle off any app that you are running on your computer or your phone, and the data you generate and create is not encrypted, let alone automatically backed up.

BM: Are there other security measures you’ll be employing?

PP: We’ve also added two-factor authentication, although I fundamentally hate it from a user experience point of view. Two-factor is particularly problematic and a poor approach if the second factor for authorizing access is a phone number or email address. It’s better than nothing, but it’s not what one would consider to be “good two-factor.”

BM: Is there a solution to this?

PP: Yes, since 2015, we’ve been employing what we call “one touch, two-factor,” where we take two-factor and make it invisible by baking it in our Airbitz app. This eliminates the need for notification by SMS or email, or via an app like Authy or Google Authenticator.

BM: Can you talk a bit about password recovery? This can be a big issue with crypto users.

PP: It is indeed. Think about this for a moment: If you lose your mobile phone or other type of device, in the Google Authenticator world you have just lost your access completely. So, it’s up to the service you are using to determine a recovery mechanism. What’s interesting is that some services don’t give you one. Others offer recovery via email, SMS, or other similar mechanism which then introduces the same issue. We, therefore, believe in recovery via time lock, where your account is locked for a period of time before you can reset it.

BM: In the meantime, are there ways to prevent users from losing their password in the first place?

PP: There is some psychology involved here. Part of our philosophy at EdgeSecure is to carefully align technology with humanity. This involves a recognition of the fact that we’re all fallible beings, that we do forget passwords. One step we employ to help people not forget passwords is to ask them to voluntarily enter it from time-to-time when they go to access their app. Our intent is to give them the opportunity to change it if they forget it at that moment.

BM: How exactly does this work?

PP: We have an algorithm inside of the app that has what we call a reminder “step off,” based on users actually entering it. This “step off” is how frequently we remind you based on how many times you’ve actually entered the password in the past. Obviously, you can get into the app with a pin, thumbprint and now facial ID. But if you lose that device, the password is the only way to get back on.

BM: This seems like an idea that other tech solution providers will likely want to pick up on.

PP: No doubt. We fashion ourselves as the world’s only password recovery for encrypted data. While that, in and of itself, is a patentable idea, we’ve opted to not patent, in the name of open source, open collaborative effort.

BM: What sort of criticism do you hear from the crypto community?

PP: One of the main ones we get is that we are not as secure as a hardware wallet. These criticisms come from people that often harbor the biggest fears of something that I have yet to see happen, namely, a person losing crypto from a device attack. Sure, you might hear of publications espousing theoretical exploits. But I haven’t seen evidence of a mass exploit with cryptocurrency taken on a device with encrypted data. Yet there are millions, if not billions, of dollars being poured into solutions for that problem.

BM: Aren’t hardware wallets a great resource then for those who have these concerns?

PP: They can be. But it’s important to keep in mind that with hardware wallets, the attack vector isn’t someone getting into it digitally over the internet. Rather, the attack vector is the individual user. I can’t count the number of people who say to me after purchasing a hardware wallet, “Now, I’m secure!” I then ask them, what did you do with the backup information? Often they’ll say, “I put it on Google Drive.” My response: “You did what? That’s the worst thing you could possibly do with the private key.”

BM: Finally, what are your thoughts regarding security vulnerabilities among centralized exchanges?

PP: It’s a big concern, no doubt. Coinbase is obviously the most recognizable example in the crypto world, but I don’t think that their model can survive long term. I’d describe them as a $15 billion piƱata for hackers. Yes, they haven’t been hacked and I believe a combination of luck and skill has prevented that from occurring.

BM: So do you believe that it’s just a matter of time before a serious hack occurs?

PP: Let me say this. One of the hardest aspects of centralized security is that it doesn’t scale. In other words, the bigger you get, the harder it is for you to secure. And as the pot becomes bigger, you have to hire and entrust more and more people inside the company. So it takes just one bad apple with access and there goes a lot of user money.

BM: Where do you see this security space headed?

PP: In the next 3–5 years, we should actually see a trend where users will seek out what I call Edge-secured apps, where people can control their own data. These encryption and Edge solutions will be invisible to those using the app, which will go a long way toward enhancing user experience along with security and privacy.

Physical Bitcoins: Our Hands-On, End-to-End Review of Opendime

https://opendime.com/

Opendime is a tiny USB flash drive that can be loaded with bitcoin by the first user and given to another user, who is, in turn, able to pass it along to a third user and so forth.

The private key attached to each Opendime is generated by the device at the time of setup by the user: It is not known by anyone, not even by the first owner or by the Opendime company itself. Opendimes can be passed along multiple times to other users and verified. An Opendime stick can only be redeemed by the last user, who must break the device to access the private key and import it into a bitcoin wallet.

A pack of three Opendimes can be ordered for $37.50. Though perhaps too technically demanding for casual Bitcoin users and arguably too expensive for transferring small values (the device is useless after getting the funds out), Opendimes are certainly usable as physical bitcoins.

“Opendime transactions are a little different from blockchain transactions,” notes the Opendime FAQ. “Whenever two people meet and trade goods or services for an Opendime, you could say a transaction has occurred, and yet there is nothing recorded on the blockchain. This is different from a normal bitcoin wallet which makes blockchain records continuously and can create a complex web of connections, which can later be explored by anyone.”

In other words, Opendimes can be used as totally anonymous, untraceable bitcoin cash. It is possible to do something similar with a paper wallet by printing a bitcoin address and its private key and then passing the paper wallet to another user, with no trace of the transaction recorded on the blockchain. “It is much more private because there is no subsequent blockchain transactions to track,” confirmed Opendime developer Rodolfo Novak in conversation with Bitcoin Magazine.

But the problem with using paper wallets in this way is that, somewhere along the transaction trail, someone could copy the private key and take the funds at any point after passing the paper wallet to the next user. Opendime solves this problem by hiding the private key, only revealing it to the last user who must break the device to take funds out.

Users of Opendime sticks can choose to pass their stick along to different owners only a few times before being emptied and destroyed, or they can treat their stick like physical cash, allowing it to change hands many times over years or decades. Novak confirmed that, according to user feedback, both scenarios are well used.

With bitcoin exchanges under increasing regulatory pressure, it seems likely that face-to-face exchanges like LocalBitcoins could become more popular, which could boost the adoption of Opendime. Novak confirmed that, indeed, users are pre-loading Opendimes and using them to sell bitcoin via LocalBitcoins.

According to Novak, Opendime is not vulnerable to regulatory actions because “the devices are ‘point solutions’ without any central service to be regulatory ‘captured.’”

Legally, Opendime is a trademark/product of Coinkite Inc., a company founded by Novak and Peter Gray and based in Toronto, Canada. Novak is skeptical of the possibility that Canadian regulators could order Coinkite to stop producing and selling Opendimes. “We and our lawyers don’t believe that’s a possible scenario,” he said.

Opendime documentation claims the sticks will last for decades under normal usage conditions; however, Opendime hasn’t been around for decades, so there’s no way to know for sure. But, as Novak explained, the microchip used in each Opendime is rated for 25-100 years, as per the data sheet (page 816) linked in the FAQ.

“A few users have put it through a lot of abuse, washing machines, freezing, water, etc. and it survived,” said Novak

Novak also stated that it’s not practically possible to make a counterfeit because the device has a high security chip with a factory key just for that reason.

“They would have to break our private key, which is practically impossible,” said Novak. “Not even with a few tens of millions of dollars could they peel the chip and try to use an electron microscope to get our key because our chip choice also protects against peeling. So maybe a hundred million dollars could make that happen. If that happens the next batch would have a new key and they would have to spend the money again.”

The possibility remains, however, that malicious parties could make fake Opendimes, with an identical look and user interface, which claim a fake balance confirmed by a fake verification process. Therefore, it’s important to check the provenance of the device. Novak explained that there are a few ways for users to check an Opendime signature to verify it’s not counterfeit, including a Chrome extension, the Samourai Wallet, which supports Opendime natively, Electrum (coming soon) and an open-source script.

Gray added that each Opendime ships with Python code for verification. “You can use a known-good Opendime to verify an unknown one,” he said. “No internet is required, and self-contained python code is used — just one command to be typed, which takes just seconds.”

How It Works

Anytime the stick is plugged into a computer, flickering green and red lights indicate its status. Only green means that the device is active; red indicates either that the device hasn’t been activated or that it has already been unsealed (broken) and can’t be used anymore. The lights work correctly even without a computer, with the stick connected to a USB charger or power pack. A file named index.htm on the stick provides all status information.

Bitcoin Magazine tested an Opendime stick end-to-end. When we plugged the Opendime stick into a computer for the first time, the red light flickered. The index file warned, “Your Opendime is new and unused. Follow these steps to pick a private key,” and gave us detailed instructions.

Following the instructions, we copied a few small files onto the device to seed a random number generator, which gets random bits from random.org. Once the private key was generated, the index file showed the stick’s Bitcoin address and a corresponding QR code.

Besides the index file and two folders with programs and utilities, there are four files on the stick: Address.txt, Private-key.txt, Qrcode.jpg and README.txt. The address and Qrcode files show the stick’s bitcoin address in both formats. The private-key file reads: “SEALED — See README.txt for details.” The README gives detailed instructions on how to use the Opendime stick, including how to verify that the device is authentic and how to get funds out.

The index file shows two status check buttons: “Check Balance” and “Verify.” Pressing the Verify button resulted in the status message “VERIFIED: Your Opendime does have control over the secret private key corresponding to Bitcoin payment address.” The balance was zero, of course, because we hadn’t yet sent funds to the stick.

We sent funds to the stick in multiple transactions from different users, physical locations and bitcoin wallets. After all the transactions were confirmed, the correct balance and previous transactions were displayed in the index file.

Now our Opendime stick was active, loaded and ready to be passed along to other owners. If the stick has been loaded with, say, 10,000 bits (0.01 BTC, about $120 at the current exchange rate), the stick could be used as a physical coin carrying that value.

 At this point in the process, anyone in the ownership chain could decide to empty the stick and transfer the funds to their bitcoin wallet. To do that, the user must unseal the device by pushing a pin through a little circle marked on the back of the device. When this is done, the red light flickers and the index file displays a warning: “UNSEALED ⚠ DO NOT send more funds to this address or accept this hardware as payment.” Clicking both status check buttons results in a further warning: “Bitcoin was spent from this address. If this is an Opendime address, this means it has been UNSEALED.” The private key is now shown in the index file.

The Opendime team recommends using the Samourai wallet. However, we decided to experiment and create a new wallet on blockchain.info. We imported our Opendime private key (Settings – Addresses) and transfered the funds to the blockchain.info wallet, and then to an exchange.

In summary, the Opendime stick passed our end-to-end test with flying colors. One caveat: At $13 a piece, Opendime sticks struck us as rather expensive for storing/transferring small amounts and may be better suited to large amounts of over $1,000 or so.

“But $13 is actually very cheap as it’s amortized by multiple exchanges of the same unit,” Novak suggested. “Also, Bitcoin transactions are very often more than that.”

This is a fair point, since the chain ownership transfer could go on for a very long time, with the stick potentially changing hands many times, just like physical cash. Novak also added that improvements and new features are in the works.

Study Suggests 25 Percent of Bitcoin Users Are Associated With Illegal Activity

Study Suggests 25 Percent of Bitcoin Users Are Associated With Illegal Activity



In a newly published paper on the use of bitcoin for illegal activity, researchers from the University of Sydney, the University of Technology Sydney and the Stockholm School of Economics in Riga indicate that a quarter of all bitcoin users are associated with illegal activity.

The use of bitcoin for illicit purposes has long been the most controversial aspect of the cryptoasset, although it has taken a back seat to speculation around the bitcoin price over the past few years.

In addition to estimating the scale of illegal activity involving bitcoin, the research paper also claims this sort of activity accounts for a significant portion of bitcoin’s intrinsic, underlying value.

Methodology

In the paper, which was co-authored by Sean Foley, Jonathon R. Karlsen and Tālis J. PutniņŔ, publicly available information is used as the basis to identify an initial sample of users involved in illegal activity on the Bitcoin blockchain. Seizures of bitcoin by law enforcement, hot wallets of darknet markets, and Bitcoin addresses on darknet forums are used here, in addition to the trade networks of users who were identified in this data set.

Additionally, the researchers use a formula of their own creation to detect users likely to be involved in illegal activity by analyzing the entire public blockchain up until the end of April 2017. The formula for detecting criminals on the blockchain involves a wide variety of metrics such as transaction count, transaction size, frequency of transactions, number of counterparties, the number of darknet markets active at the time, the extent the user goes to conceal their activity and the degree of interest in bitcoin in terms of Google searches at the time.

“Bitcoin users that are involved in illegal activity differ from other users in several characteristics,” the paper says. “Differences in transactional characteristics are generally consistent with the notion that while illegal users predominantly (or solely) use bitcoin as a payment system to facilitate trade in illegal goods/services, some legal users treat bitcoin as an investment or speculative asset. Specifically, illegal users tend to transact more, but in smaller transactions. They are also more likely to repeatedly transact with a given counterparty. Despite transacting more, illegal users tend to hold less bitcoin, consistent with them facing risks of having bitcoin holdings seized by authorities.”

The paper also notes that bitcoin transactions between illegal users are three to four times denser, meaning those users are much more connected to each other through their transactions. This is consistent, the paper says, with illegal users taking advantage of bitcoin’s use as a medium of exchange, while legal users tend to view the cryptoasset as a store of value.

The Scale of Illegal Activity on the Bitcoin Network

As with any research into the activities of criminals on the internet, it’s important to take the findings of this study with a grain of salt. Remember, this is a study on the activities of those who do not wish their activities to be discovered in the first place.

For example, another study Bitcoin Magazine reported on last week indicated a much lower level of illegal activity — albeit limited to the concept of bitcoin laundering — on the Bitcoin network than what was found in the study being reported on today.

Having said that, here are the levels of illegal activity on the Bitcoin network, according to the study:

  • 24 million illicit users, which is 25 percent of all users
  • 36 million illicit transactions per year, which is 44 percent of all transactions
  • $72 billion worth of illicit transactions per year, which is 20 percent of the dollar-value of all transactions
  • $8 billion in illicit bitcoin holdings at the time of the study
  • 51 percent of all bitcoin holdings throughout bitcoin’s history have been illegal in nature

The study compares Bitcoin’s black market to the markets for illegal drugs in the United States and Europe. In the United States, this market is worth $100 billion per year. In Europe, the market is 24 billion euros on an annual basis.

“While comparisons between such estimates and ours are imprecise for a number of reasons (and the illegal activity captured by our estimates is broader than just illegal drugs), they do provide a sense that the scale of the illegal activity involving bitcoin is not only meaningful as a proportion of bitcoin activity, but also in absolute dollar terms,” the paper says.

More Takeaways from the Paper

While the amount of illegal activity taking place on the Bitcoin network appears to be relatively large, the paper indicates that the prevalence of this sort of activity has been declining since 2015 as more mainstream users have entered the market due to the interest in bitcoin as a store of value or speculative asset.

The paper notes that the illegal activity involving bitcoin is inversely correlated to the number of searches for “bitcoin” on Google.

“Furthermore, while the proportion of illegal bitcoin activity has declined, the absolute amount of such activity has continued to increase, indicating that the declining proportion is due to rapid growth in legal bitcoin use,” says the paper.

The paper also indicates that privacy-focused altcoins, such as Monero and Zcash, may be cutting into bitcoin’s role as the currency of the online black market.

The paper notes that it’s currently unclear if bitcoin is leading to an increase in black market activity or if this is simply offline activity moving onto the internet.

“By providing an anonymous, digital method of payment, bitcoin did for darknet marketplaces what PayPal did for [eBay] — provide a reliable, scalable, and convenient payment mechanism,” the paper adds.

According to the paper, this use case is the underlying value of the bitcoin asset.

“Our paper contributes to understanding the intrinsic value of bitcoin, highlighting that a significant component of its value as a payment system derives from its use in facilitating illegal trade.”

In addition to implications the online black market could have on the valuation of the bitcoin asset (a claim that is highly speculative as the bitcoin price has continued to see tremendous gains in the face of declining use for illicit payments), the paper adds that this realization also has ethical implications: those who choose to speculate on the bitcoin price may question whether they wish to provide liquidity for a payment system that enables illegal online transactions.

Op Ed: Here’s What Paul Krugman Got Wrong in His Bitcoin Tweetstorm

Op Ed: Here’s What Paul Krugman Got Wrong in His Bitcoin Tweetstorm



Like many other mainstream economists, Paul Krugman has long-shown a complete disdain for Bitcoin. In late 2013, he went as far as to write a piece titled “Bitcoin Is Evil” for his column in The New York Times.

Moral objections to bitcoin are one thing, but Krugman also does not see much utility in the cryptoasset at all. While he has been able to express his hatred for Bitcoin quite clearly, his technical criticisms of bitcoin as a new type of asset and store of value leave something to be desired.

In a tweetstorm on Sunday, January 21, 2018, Krugman illustrated his ignorance on the usefulness and utility of bitcoin around the world.

Starts Out Well Enough With the Digital Gold Analogy

Krugman’s tweetstorm started out well enough. In fact, the opening tweets were likely some of the nicest things the Nobel Laureate has ever had to say about bitcoin.

“As I see it, cryptocurrencies like Bitcoin are in effect like digital gold coins, in the sense that they can’t be counterfeited … Cryptocurrencies use cryptographic techniques plus distributed storage to create non-material entities that are nonetheless impossible to fake,” tweeted Krugman.

Digital gold is still the best analogy to sum up the digital asset’s value proposition, and the utility of bitcoin should become more apparent as the world moves deeper into a cashless society. In a cashless society, bitcoin would become the last financial bastion of freedom in a world where the global financial system is under complete control of governments.

The Avoidance of Trusted Third Parties in Payments Is a Big Deal

After those tolerable first few tweets, Krugman goes off the rails with the claim that online payments that don’t involve a trusted third party aren’t that important.

“Cryptocurrency lets you make electronic transactions; but so do bank accounts, debit cards, Paypal, Venmo etc. All these other methods involve trusting a third party; but unless you’re buying drugs, assassinations, etc. that’s not a big deal,” tweeted Krugman.

First all of all, there’s no reason to bring morals into an exploration of bitcoin’s utility. Either people will use it or they won’t. Whether you like what they’re doing is a different matter. Bitcoin’s use in darknet markets, ransomware, online gambling and other fringe areas cannot be ignored. Utility is utility.

Secondly, not everyone has access to PayPal, Venmo, and other online payment platforms. These options are centralized and permissioned. They’re also highly regulated, which means plenty of people fall through the cracks and cannot gain access to them.

Online freelancers in Venezuela take bitcoin because their government and payment platforms like PayPal have failed them.

https://platform.twitter.com/widgets.js

Krugman goes on to point out the clunkiness of Bitcoin as it exists today, and he’s generally correct on this front. But this does not mean there’s no utility here. In fact, the opposite is true: There is so much utility that it has become difficult to scale the system to all of the people who want to use it.

Complaining about the lack of cheap, user-friendly payments on Bitcoin today is analogous to someone in 1995 complaining that the internet doesn’t have Netflix. Just give it a minute. Payment layers are currently being built on top of the base Bitcoin blockchain, with the Lightning Network being the most obvious example.

The Claim That Bitcoin Has Nothing to Backstop Its Value

Krugman then turned to the often-used argument that bitcoin lacks any sort of underlying value. This should come as a surprise, since he just laid out how it is useful for illicit digital payments.

“Meanwhile, what backstops a cryptocurrency’s value? Paper money is ultimately backed by governments that will take it in payment of taxes (and central banks that will reduce the monetary base in case of inflation). Gold is actually useful for some things, like filling teeth and making pretty jewelry; that’s not most of its value, but it does provide a tether to reality, along with a 5000-year history,” tweeted Krugman.

“Cryptocurrencies have none of that,” Krugman continued. “If people come to believe that Bitcoin is worthless, well, it’s worthless. Its price rise has been driven purely by speculation — by what Robert Shiller calls a natural Ponzi scheme, in which early entrants make money only [because] others buy in.”

If bitcoin is useful for permissionless digital payments, then it has the same sort of underlying utility that the U.S. dollar has in the form of tax payments.

Additionally, the U.S. dollar would also become worthless if people woke up one morning and came to believe that it was worthless.

Of course, all of this misses the point anyway. How much of the value of all the U.S. dollars in the world comes from its use in tax payments? How much of the value of all the gold in the world comes from its use in electronics? Not much.

Krugman misses that storage of value is also a form of utility, and bitcoin is the most uncensorable, unseizable store of value the world has ever seen. You can walk around with a passphrase in your head that can unlock access to thousands of bitcoins, and no one would be the wiser. Not to mention there is no centralized party that can inflate the supply.

The Point of Market Manipulation

Krugman also touched on the high potential for manipulation in the bitcoin market, pointing to a paper regarding the manipulation of the bitcoin price by now-defunct bitcoin exchange Mt. Gox, as an example.

This is another claim with some basis in reality, but it ignores the massive amounts of manipulation and lack of transparency in the traditional financial system, which is what led to the creation of bitcoin in the first place.

Through the use of cryptographic proofs, bitcoin has the potential to become much more transparent and trustless than the traditional financial system. Bitcoin’s monetary policy is already much more transparent than what goes on at the Federal Reserve. There’s a reason someone put up a “Buy Bitcoin” sign while Federal Reserve Chairwoman Janet Yellen spoke against the need for further audits of the central bank.

Bitcoin exchanges are highly centralized institutions, which opens the door for manipulation. However, these exchanges have also become much more regulated over time. Today, it’s far more difficult to run an exchange at the level of incompetence that was found at Mt. Gox.

The potential for market manipulation should decline as the technology around bitcoin improves. Eventually, more trades may take place on decentralized exchanges, where it’s impossible to fudge the numbers.

In his last tweet from his thread on Sunday, Krugman said it’s unclear if the Bitcoin blockchain — or any blockchain for that matter — is useful.

Around $3 billion worth of bitcoin has been transacted on the Bitcoin network per day this year, according to Blockchain; $75 million worth of bitcoin per day was the norm the day Krugman first published an article on the subject.

Krugman’s arguments, as well as arguments from other well-known economists, have not changed much since 2013, but the Bitcoin network has continued to grow. It’s possible that Krugman and his colleagues are unable to comprehend the usefulness of bitcoin as an asset because it does not fit into the regulated, controlled environment they’ve built their economic and political worldviews around.

Bitcoin cannot be tamed, and they hate that.

Bitcoin Price Analysis: Potential Bearish Continuation Sets Up Lower Lows

Bitcoin Price Analysis



Shortly after a sharp drop from the mid $14,000 to the lower $9,000s, bitcoin saw a strong bounce to the upper $11,000s. At the time of this article, bitcoin appears to be consolidating and is ready to make its next move:

In the previous BTC market analysis, we discussed the distribution trading range the market fell out of as it reached for lower support boundaries. Ultimately, it found support on the macro 50% retracement values near $10,000. Once it broke south of the trading range, the price fell sharply and with high volume:

After bouncing off the macro 50% values, the market rallied and ultimately tested the linear trendline shown in Figure 1. Now, after several failed attempts to break the linear trendline’s resistance, the market finds itself in a consolidation pattern where it decides where it will move next.

Figure 3: BTC-USD, 60 Minute Candles, Potential Bear Flag

One possibility to keep a close eye on is this potential, strong bear flag. After finding support on the macro 50%, the subsequent rally saw decreasing volume throughout the length of the movement. This sort of price action could potentially lead to a bearish continuation with a measure move between $4000 and $5000 — a price target of approximately $6,000 – $7,000. If a drop of this magnitude continues the downtrend, we can expect to find support on the 61% macro Fibonacci retracement values shown in Figure 1.

It’s important to note that bitcoin has a penchant for breaking upwards when all signs say “down,” so tread lightly and wait for confirmation of the move. Confirmation of the bear flag breakout would show a pretty obvious outlier in volume, combined with wide price spread.

Summary:

  1. Bitcoin recently saw a steep drop in price where it ultimately found a local bottom in the low $9,000s.
  2. Since it bottomed out, it has seen a rally on decreasing volume which leaves the door open for a bearish continuation.
  3. If the bearish continuation continues, expect support on the 61% macro retracement values.

Two New Services Could Help Investors Rate Cryptocurrencies

Cryptocurrency Rating Services Launched



Increasing interest in cryptocurrencies has led to an influx of new investors. Unlike traditional markets, there are few tools that can help people make informed decisions, a situation that has already begun to claim victims in a particularly volatile environment.

In separate announcements, Weiss Ratings and Intercontinental Exchange (NYSE: ICE) have announced the introduction of new financial tools to help investors navigate the cryptocurrency market and make smarter investments.

Weiss Ratings, an established independent rating agency of financial institutions, says they will begin issuing ratings for cryptocurrencies on January 24, 2018, to help investors make informed decisions.

ICE, an operator of a network of global futures, equity and equity options exchanges, is partnering with blockchain technology provider Blockstream to launch the Cryptocurrency Data Feed (CDF).

Weiss Ratings Takes On Cryptocurrencies

Founded in 1971, Weiss is an independent rating agency of financial institutions. They will begin issuing letter grades for cryptocurrencies including Bitcoin, Ethereum, Ripple, Bitcoin Cash, Cardano, NEM, Litecoin, Stellar, EOS, IOTA, Dash, NEO, TRON, Monero, Bitcoin Gold and many others.

According to Weiss Ratings founder Martin Weiss, the data they are using is a combination of purchased data and data collected through other sources. It is updated on a daily basis, covering a sliding 12-month window.

Regressive testing to verify past data that the company uses to confirm predictions is still ongoing, but results have been accurate thus far, Weiss told Bitcoin Magazine.

“We have built an analytical technology over the years using intelligent models to replicate the real world and we are applying [these] to cryptocurrenc[ies]. These have been very accurate for many years.”

Ratings are built up across multiple indexes. The company built new models to reflect cryptocurrency data and developed an overall grading system that is broken down into four separate sub-models:

  1. Risk Index — The level of risk involved in the investment, based on factors like price activity and volatility.
  2. Reward Index — The potential reward outcome, based on historical patterns of buying and selling.
  3. Technology Index — A primarily manual process, where company analysts review the source code and white papers, analyze price movement and make ratings in a Query Tree (their internal software) to generate a quantitative result.
  4. Adoption Index — A measurement of adoption along two dimensions: how broadly it is adopted, transaction speed, settlement times, etc.

“A weighted average of those 4 indices is used to get the final grade,” said Weiss. “The goal at Weiss is to empower the investor to make prudent decisions.”

ICE Data Services: Real-Time Trading Data

The Cryptocurrency Data Feed (CDF) is a multi-asset and multi-venue data feed, capturing nearly 80 percent of cryptocurrency exchange trading volume over more than 15 exchanges around the world. It measures leading cryptocurrencies against the U.S. dollar and other major currency pairs.

The captured data is normalized to create a unique number sequence to identify the transaction, details of where the trade took place, quantity, price, currency, timestamp and other relevant order book data. This is designed to enable ICE Data Services’ customers to receive global market–representative trading data in a real-time feed with high-quality information.

“With the broad array of cryptocurrencies and exchanges, and given the price variances between exchanges, it’s critical that investors have a comprehensive source of pricing information,” said ICE Data Services President and COO Lynn Martin in a statement.

According to Blockstream SVP of Business Affairs Alex Fowler, the initial exchange partners set up through cooperative agreements include Bitbank, Bitfinex, BitMEX, Bitso, Bitstamp, BtcBox, BTCC, CEX, Coinfloor, Coincheck, itBit, GOPAX, OKEx, SurBTC, The Rock Trading, Unocoin, Vaultoro and Zaif, with more coming soon.

The data is collected using the exchanges’ APIs and, in some cases, by setting up dedicated connections with them. The current feeds lack standardized formatting and information: part of what ICE is providing is a single source that consolidates and standardizes the data, which will average out the information from the multiple sources into a more accurate overall view.

Historically, the data currently only goes back to the initial integration; however, Blockstream is working with the exchanges to try and incorporate older data as well.

Fowler told Bitcoin Magazine, “We believe that a consolidated data source, resulting from the combined participation of a strong and growing list of exchange partners globally, will enable us to address these gaps and thereby promote better liquidity, price stability, and public confidence in cryptocurrency as asset class.”

CDF will include bitcoin and a wide range of cryptocurrencies and currency pairings on launch; the final list will be on their website. ICE will develop and publish a selection of criteria for decisions on the addition and/or removal of assets in the feed. This will be an ongoing process as the market evolves. Access to the real-time CDF will be available to subscribers of ICE Data Services’ Consolidated Feed in March 2018.
