“Bitcoin Laundering” Study: Where Do Criminals Turn to Mask Illicit Cryptoassets?

Bitcoin laundering study

A recent study (PDF) from the Foundation for Defense of Democracies’ Center on Sanctions and Illicit Finance and blockchain analytics company Elliptic explored the “bitcoin laundering” ecosystem. In the study, Elliptic’s forensic analysis of the Bitcoin blockchain and other publicly available data were used to track the flows of illicit funds from 2013 to 2016.

“This study aimed to identify where individuals turn in order to cash out or transmit bitcoins (BTC) acquired from illicit entities and to discover typologies for criminals ‘laundering’ bitcoins,” the report says.

The study describes bitcoin laundering as a special type of money laundering that exists within the Bitcoin network where a user moves some bitcoins to a new address in a manner that obscures the original source of funds. The conversion of bitcoins into fiat currency on exchanges that lack adequate anti-money laundering (AML) and know-your-customer (KYC) policies can also fall under the category of bitcoin laundering.

In addition to describing the common mechanisms for bitcoin laundering and explaining that this sort of activity is a small percentage of all transactions sent to exchanges and other conversion services, the study also offers some recommendations for law enforcement in terms of preventing the masking of illicit funds on the Bitcoin network.

It should go without saying that any study related to the dark web or illicit use of the Bitcoin network needs to be taken with a grain of salt because avoiding detection is the whole reason for a criminal to use these sorts of platforms in the first place.

The Bitcoin Laundering Ecosystem

Much of the study, which is titled “Bitcoin Laundering: An Analysis of Illicit Flows Into Digital Currency Services,” revolves around the use of “conversion services.” Conversion services are basically platforms where users convert bitcoins to fiat currency (a Bitcoin exchange) or another cryptocurrency (a cryptoexchange), or move the bitcoins to another Bitcoin address accessible to the user. This results in a flow of funds that cannot be viewed or traced directly on the public blockchain.

According to the study, darknet markets are the main source of funds that are sent to conversion services in bitcoin laundering attempts.

Additionally, the number of illicit services that could be the source of “dirty bitcoins” sent to a conversion service increased fivefold from 2013 to 2016. Having said that, the study finds that the sources of illicit funds entering conversion services are quite centralized.

“Only a small number of entities account for the majority of illicit activity in our sample,” the study says. “Nine of the 102 illicit entities were the source of more than 95 percent of all laundered bitcoins in our study. All nine were darknet marketplaces.”

bitcoin-laundering_Figure1.png

While exchanges are the most commonly used type of conversion service, bitcoin mixers and gambling sites have much more illicit funds coming into their platforms as a percentage of their overall transactions. As potential conduits for bitcoin laundering, these two types of conversion services benefit from concealing their country of operations and avoiding enforcement of AML regulations.

“Fewer than 10 percent of all transactions overall passed through unknown jurisdictions ... while 52 percent of illicit laundering went through them,” the study says.

Much like the sources of illicit funds, the conversion services where these funds are sent are also highly centralized, the study finds. The data indicates that 97 percent of illicit transaction volume at mixers and gambling sites goes through three different entities. Additionally, two platforms in Europe account for half of all illicit transfers that go into exchanges.

Not Much Bitcoin Laundering Activity Overall, and It’s on the Decline

Another notable aspect of the study is that the data indicates a low level of bitcoin laundering as a percentage of all payments sent to conversion services.

“The amount of observed Bitcoin laundering was small (less than one percent of all transactions entering conversion services),” notes the study.

The report clarifies that the actual volume of illicit Bitcoin transactions sent to conversion services is “almost surely to be significantly larger” than what the data in the study shows because intermediate transactions are not counted. In other words, the report only covers transactions made directly from an illicit source, such as a darknet market, to a conversion service.

The study also indicates a decrease in illicit Bitcoin transaction volume going to conversion services over time.

bitcoin-laundering_Figure2.png

“It is likely that illicit bitcoins fell as a percentage of total volume entering conversion services due to the cryptocurrency’s increasing popularity as a speculative investment as well as new laundering techniques,” the study says. “The drop may also reflect better AML/CFT compliance by conversion services, including the use of blockchain analysis services to determine customers’ source of funds.”

The study later adds, “Our study, the first of its kind, indicates that while most types of conversion services have received some bitcoins from illicit activity, the vast majority of the funds they receive do not appear to be illicit.”

Recommendations for Law Enforcement That Will Likely Fall Short

The report offers recommendations for law enforcement in terms of what they can do to combat the effectiveness of bitcoin laundering.

First, the study says proper KYC and AML policies need to be enforced on the bitcoin mixers and gambling sites that allow for anonymous usage. It notes that the three conversion services that account for 97 percent of bitcoin laundering on these types of platforms should be targeted by financial authorities.

“The fact that most mixers and gambling sites hide their location of operations indicates they probably seek to evade the basic regulations in place to uphold transparency and financial integrity standards in most jurisdictions,” adds the study.

Of course, it should be noted that targeting these sorts of services will become nearly impossible as they become more decentralized over time. Decentralized platforms like JoinMarket, TumbleBit and ZeroLink remove the ability for authorities to clamp down on bitcoin mixing in an effective manner, as these solutions act more as software than services.

Second, the report also calls for increased AML and KYC compliance at European exchanges.

“Many large European Bitcoin exchanges do implement robust AML policies,” says the study. “However, this is out of choice rather than obligation, and there are some who choose not to, possibly to attract business from criminals.”

The study adds that the European Union is already moving in the right direction via an update of their 2015 Anti-Money Laundering Directive to include fiat-to-cryptocurrency exchanges, but in the view of the authors of the paper, crypto-to-crypto exchanges must also be regulated in this manner.

Again, it needs to be pointed out that more problematic technology — at least from law enforcement’s point of view — is on the horizon in the form of decentralized cryptoexchanges. Through the use of cross-chain atomic swaps via the lightning network, users will be able to instantly trade between different cryptoassets without the need for a trusted third party.

Third, the study calls for a sort of propaganda campaign against the use of darknet markets by criminals and the general public at large.

“Law enforcement should increase customer skepticism about [darknet market] sites’ integrity and reduce the perceived security of such platforms by exposing their vulnerabilities publicly,” says the study.

The report adds that law enforcement should make it well known that they’re lurking on these darknet markets to further shake confidence in them.

Darknet markets are another area of the Bitcoin ecosystem that are becoming more decentralized through platforms such as OpenBazaar. While illicit activity on the OpenBazaar network appears to be limited at this time, it could potentially explode in popularity as a reaction to law enforcement’s hypothetical campaigns against the centralized darknet markets.

Fourth, the report praises the decision by financial authorities in the United States to regulate exchanges as Money Service Businesses. The authors of the paper would like to see this sort of policy rolled out worldwide.

Last, the study notes the need to prevent the illicit use of bitcoin and other cryptocurrencies to get around economic sanctions imposed by the United States or other nations.

“In addition to mitigating illicit finance risks like criminal money laundering, there will likely be a need to develop strategies to counter state actors aiming to use cryptocurrencies to circumvent U.S., EU, and UN sanctions.”

Recently, there have been reports of North Korea, Russia and Venezuela all looking into separate mechanisms for avoiding economic sanctions through the use of cryptocurrencies.

Halong Mining and MyRig Announce Partnership

dragonmint.png

Halong Mining and MyRig are working together to bring the new DragonMint miner from Halong to market.

First announced in November 2017, the new Halong Mining DragonMint 16T miner is the result of 12 months of R&D and a $30 million investment in development. It has a hashrate of 16th/s with a power consumption of 1440–1480 watts optimized for 240v operation. The DM8575 ASIC runs at 85 GH per chip with a power efficiency of 0.075 J/GH. No special modifications are needed in a data center to use the DragonMint if it is already configured to support a typical Chinese-manufactured ASIC miner.

MyRig (formerly BitmainWarranty) has been providing hosting and retail sales of miners and accessories, PCB design and manufacturing, software engineering and factory approved warranty and repair services since 2013. The partnership with Halong means that MyRig will take care of retail-side distribution, support and warranty services for the DragonMint 16T.

Halong will be manufacturing the DragonMint and continue to sell direct, albeit with a five-unit minimum. Halong told Bitcoin Magazine that the five-unit minimum per order on their site will remain when ordering direct from Halong, but when ordering from MyRig, customers will be able to order single units. They indicated that lead time for shipping at the moment is April 15–30, 2018, and they expect the first batch to go out in March 2018.

According to a MyRig representative, they will ship to any country that either UPS or DHL can deliver to, provided it is not on a sanctions list.

Hyperledger’s Behlendorf: 2018 Will Bring Breakthrough Blockchain Developments

hyperledger_behlendorf.png

Brian Behlendorf is confident that 2018 will be a peak year, not only for Hyperledger — the international consortium of companies and organizations developing open source, permissioned blockchain technology — but also for blockchain technology in general as businesses and governments recognize the potential power of distributed ledgers and smart contracts.

“2018 will be the year that Hyperledger and blockchain come into their own. Projects demonstrating real world solutions, like Change Healthcare, that will enable healthcare systems to better and more efficiently process claims and payments, will launch this year.”

Hyperledger, founded in 2015, incubates and promotes blockchain technologies for business, including distributed ledgers, client libraries, graphical interfaces and smart contract engines.

Their 200 members include leading companies in finance, banking, Internet of Things, supply chains, manufacturing and technology development.  

“2017 was a milestone year for Hyperledger both for new members and for new technical breakthroughs. In 2017 we doubled our membership, gaining companies like American Express, Cisco, Daimler and Baidu, and we’re expecting more companies and organizations to join in 2018,” said Behlendorf.

“On the technical side, 30 companies and more than 100 developers contributed to the launch of the first production ready Hyperledger blockchain framework called Hyperledger Fabric,” he added.

According to Behlendorf, an important part of Hyperledger’s mandate is to also help educate and train the workforce for the many new blockchain opportunities coming in 2018.

“We’re happy to have launched our new Resource Center, and our online blockchain course is a great success with more than 45,000 enrolled and an average of 2,500 new enrollments per week.”

Hyperledger Blockchain Frameworks

In 2018, Hyperledger will start launching a number of frameworks and platforms that are currently in incubation.

“Interoperability in a multi-blockchain world will be the major focus in 2018. A number of Hyperledger projects are exploring integrations among one another including Hyperledger Sawtooth and Burrow and Indy, Composer and Quilt.”

Behlendorf expects that 2018 will also see some experimentation with different levels of permissioned access to blockchain networks.

He noted that permissioned and permissionless is more of a spectrum than a binary notion, and an important question is what the cost to join a node to a network is in any blockchain platform.

By reducing the cost of joining a networked ledger, Hyperledger hopes to enable new use cases and ways to solve problems.

“Hyperledger was started by a set of developers very focused on modest-sized permissioned ledgers, so that’s where the initial work has been, but there’s no hard limit to that. So we’re happy to look at options that make it easier, perhaps even to full permissionless frameworks,” said Behlendorf.

“I should note that our projects including Hyperledger Indy (for identity), Hyperledger Burrow (for smart contracts), Hyperledger Quilt (for interoperability) and Hyperledger Composer and Cello (developer tools) are agnostic about consensus mechanisms and would work fine with permissionless approaches,” he added.

Expect to see the following Hyperledger launches in 2018:

Quilt will offer interoperability between ledger systems by implementing ILP, which is a payments protocol designed to transfer value across distributed and non-distributed ledgers.

Sawtooth is a blockchain platform for creating and managing distributed ledgers. Sawtooth includes Proof of Elapsed Time (PoET) and a new consensus algorithm that is maintained without a central authority. It was originally proposed by Intel.

Iroha is a business blockchain framework for infrastructure projects that require the use of distributed ledger technology. It includes a chain-based Byzantine Fault Tolerant consensus algorithm. Soramitsu, Hitachi, NTT DATA and Colu originally proposed this framework.

Burrow is a smart-contract creator with a permissioned smart-contract interpreter included.

Indy is a distributed ledger with a decentralized identity designed to create independent digital identities between blockchains.

Composer is an open development tool set designed to make it easier to integrate existing business systems with the blockchain.

Qtum Forges Ahead with Development of Its x86 Virtual Machine and Expanded Network

qtum_dev.jpg

Qtum is on the move with the announcement of a partnership with Baofeng to begin running 50,000 full Qtum nodes and an upcoming x86 VM to support multiple languages for smart contracts.

Qtum is a hybrid of Bitcoin and Ethereum that is based on proof-of-stake consensus instead of proof of work, and is compatible with existing Ethereum contracts as well as Bitcoin gateways. Supporting the Ethereum Virtual Machine (EVM) wasn’t enough for Qtum co-founder Jordan Earls, who has been working on an x86 Virtual Machine for the Qtum system.

Earls comments that a great reason to build a x86 VM is to add more programming language support for smart contracts, his favorite being Rust. The overall list of objectives is much bigger though:

  • Programming Language Support
  • Standard Library
  • Optimized Gas Model
  • Unlock the full power of the Account Abstraction Layer (AAL)
  • New possibilities for smart contracts
  • First-Class Oracles
  • Blockchain Analysis
  • Alternative Data Storage
  • Explicit Dependency Trees
Bitcoin Magazine spoke with Earls with some more in depth questions about some of those items:


Bitcoin Magazine: What proof of concept or scalability testing have you done for the VM?

Jordan Earls: We have a very rough proof of concept we completed a few months ago where we integrated a prototype x86 VM into the Qtum network. This success is what led us to pursue this plan. We are confident that the x86 VM will be more scalable than the EVM, but we are thus far unsure how much. We are designing the VM and all of its APIs and other aspects to be scalable. We are making a big shift in the smart contract world where we actually reward smart-contract developers (in the form of cheaper gas costs) for limiting the features their smart contract has access to, and we are confident it will be faster than current EVM technology.  

Bitcoin Magazine: What are you doing to address the problem with x86 programming in general, where they assume near infinite memory and CPU time being available?

Jordan Earls: We think smart contract development crossed with this x86 paradigm will resemble something similar to real-time or embedded programming, where there are various constraints that developers must always be optimizing for.  

We foresee the same kind of design optimizations happening in the smart contract world as happen in the embedded world, and, for the first time, Qtum's blockchain will allow for these small optimizations to be directly rewarded for all users of the smart contract.

We know these optimizations are not cheap for smart contract developers to spend their time on, so we need to reward developers for taking such steps to keep the Qtum blockchain running smoothly and efficiently.

Bitcoin Magazine: What are some of the advantages with the Standard Library that will help keep smart contract code tight?

Jordan Earls: Currently in Ethereum, if you want to do a simple operation, like testing if two pieces of text are equal, you need to write your own code to do it.

This is a problem for a number of reasons: Developers in a secure context should rely on existing code that's been tested and verified, if possible. A naive implementation of this function will be slow, but a more complex and optimized implementation could have security problems. Deploying this code with your contract means another 100 bytes or so of wasted code that every node in the ecosystem now has to worry about.

Qtum will provide a standard library of functions that contract developers can rely on to have reasonable gas costs, secure and validated implementation and an easy to use interface. This means less bloat on the blockchain, easier to write and understand smart contracts and even a faster blockchain (since these functions can be optimized with native code).

Bitcoin Magazine: What about executable size? These x86 programs tend to be quite large.

Jordan Earls: This is true but also misleading. If I write a C program that just prints "hello world," about 8kB of that is going to just be the number "0." This is because x86 processors (as well as many others including ARM) benefit from a thing called "alignment." The important thing for Qtum is that the wasted bytes doing alignment can be discarded without performance impact. This immediately brings down that C program build to ~1-2kB.

We can reduce even more because we don't need all the baggage required by a standard program for Windows: We have our own "operating system" for smart contracts, so only a dozen or so bytes of actual setup code is wasted.

We have done some actual physical tests with these configurations to compare what an x86 smart contract might look like compared to an EVM smart contract. Our findings indicate that x86 programs are around 10–20 percent smaller than their EVM equivalent and, in many cases, significantly more so. And this was done without the standard library concept that was discussed above. We are not worried about getting usable executable sizes from x86 programs.

Bitcoin Magazine: So the language compiler has to be modified to support the VM? What kinds of modifications?

Jordan Earls: Only minor modifications need to be made. The language compilers do support our x86 VM already, but the Qtum smart contract environment is different from a traditional operating system like Windows or Linux. So, basically, the only big modification we have to make is to tell the language how to communicate with our smart-contract operating system.

Bitcoin Magazine: Is QTUM going to provide language packages or libraries to support the VM so people can just use those?

Jordan Earls: C and C++ will be the first languages we support "out of the box" because they tend to be the easiest due to the way they are designed. We also plan to support Rust. Go should easily be possible. For interpreted languages like Python and Perl, it becomes more complex and we must do research to ensure that they can be supported in an efficient and secure manner.

Bitcoin Magazine: Is this going to impact the development of your eSML smart contract language?

Jordan Earls: We are continuing to research the eSML approach and will decide at a later point if it is still a requirement to achieve our goals. We prefer to not do more work if it won't have a tangible benefit to our ecosystem.


Helping to support all this growth is the partnership announced on January 4, 2018, with Chinese video portal giant, Baofeng. With the help of Baofeng, the Qtum network will be boosted to 50,000 full network nodes, making it the most decentralized blockchain platform with the largest number of nodes with more than Bitcoin and Ethereum combined. The increased size of the Qtum system should provide for improved security, stability and speed, all of which will provide a solid base for the upcoming x86 VM later this year.

Earls projects that the x86 will be integrated into the Qtum main network in Q3 of 2018 but hopes to have a prototype to test with before Q2.

Today marks the first day of lower lows since bitcoin topped out around $20,000:

Bitcoin managed to blow through several milestones including both the parabolic and the linear trends. The linear and parabolic trends have been guiding trends for the last three years, and today bitcoin has broken parabolic support. It could get ugly:

Figure_2.JPGFigure 2: BTC-USD, 1-Day Candles, Macro Trend

What was once strong support has now become resistance as bitcoin scrambles to find a bottom. We can see quite clearly there is a line of support around $10,000 where the macro Fibonacci retracement values for the 50% retracement line exist. Any downward continuation will likely be supported in the interim. However, it’s fair to say that bitcoin is beginning a new downward trend. As stated earlier, today marks the first day of lower highs and lower lows — i.e., a downtrend.

So where does the bottom lie? That remains to be seen. What is clear, however, is that there was a systematic distribution of bitcoin from large players to the masses; and now we are beginning the next phase of the market cycle — the markdown phase. Will it be a sustained markdown? It’s too early to tell at the moment, so we will have to play it by ear.

Bitcoin is a long-time fan of violent drops and violent bounces, so it’s unclear how this downtrend will terminate. For now, I highly recommend traders stay away from smaller time frames and focus more on the macro view of things.

As we come to test the macro 50% retracement values, it’s important to view how the market responds and see how the volume reacts. If we don’t see strong follow-through on a bounce from the 50%, there could be a strong bearish continuation in its future. Volume is your friend and confirms the trend. If you don’t see strong volume following an upward bounce, it’s entirely possible you could get stuck in a bull trap — and no one wants that.

Bull traps are designed to lure aggressive bulls into long positions prematurely to create liquidity for the bearish investors in the market. If you are unsure of what direction the market is moving, there is nothing wrong with sitting out.

Summary:

  1. A potential markdown phase is under way as bitcoin sees aggressive selling pressure.

  2. Today marks the first day of lower lows in weeks and marks a potential macro downtrend.

  3. Support will likely be found at the $10,000 values, which coincide with the 50% macro Fibonacci retracement values.

BlackWallet Hacked: Warns Stellar Community Not to Log In to Site

Stellar Wallet “BlackWallet” Hacked

On January 13, an unknown hacker(s) hijacked the DNS server for BlackWallet.co, a web-based wallet for the Stellar Lumens cryptocurrency, and redirected it to their own server.

Security researcher Kevin Beaumont, who analyzed the code, said, “The DNS hijack of Blackwallet injected code, if you had over 20 Lumens it pushes them to a different wallet.” It is estimated that nearly 700,000 Lumens (XLM) were stolen, with a current value of over $400,000.

Warnings and alerts not to log into the BlackWallet site have been sent out by the BlackWallet team and other XLM users via Stellar Community, Galactic Talk, Reddit, Twitter and GitHub. Unfortunately, users continued to log in for some time, and thus, saw their funds vanish from their wallets.

Following the address of the attacker, it is possible to track the movement of funds from BlackWallet to the Bittrex exchange, where they are likely to convert the funds and cover their tracks. BlackWallet has since messaged Bittrex in an effort to coordinate with the exchange to block the hacker’s account.

In a statement on Reddit, the BlackWallet admin is suggesting that people move their funds to a new wallet using the Stellar account viewer. At the time of this writing, the BlackWallet website is returning a 404 error. Bitcoin Magazine will update this story as it evolves.

St. Louis Fed: In Some Ways, Bitcoin Is More Robust Than Many Fiat Currencies

StLouisCrypto.jpg

In a recent article on the basics of bitcoin and other cryptocurrencies (PDF), Aleksander Berentsen and Fabian Schär of the Federal Reserve Bank of St. Louis cover the usefulness of bitcoin and other alternative cryptoassets.

Throughout the article, Berentsen and Schär make the case that cryptoassets are well suited to become a new, important asset class. The duo goes as far to say that bitcoin is, in some ways, more robust than many fiat currencies.

Cryptocurrencies Are a Welcome Addition to the Current Currency System

Surprisingly, Berentsen and Schär are of the belief that cryptocurrencies are a welcome addition to the current currency ecosystem. While some critics claim bitcoin’s price should drop to zero because there is no intrinsic value found in the cryptoasset, the co-authors of the article from the Federal Reserve Bank of St. Louis point out that this argument also applies to the various government-issued currencies around the world.

“Bitcoin is not the only currency that has no intrinsic value,” states the article. “State monopoly currencies, such as the U.S. dollar, the euro, and the Swiss franc, have no intrinsic value either. They are fiat currencies created by government decree. The history of state monopoly currencies is a history of wild price swings and failures. This is why decentralized cryptocurrencies are a welcome addition to the existing currency system.”

Berentsen and Schär also cover the possibility of Bitcoin’s consensus rules eventually being changed to allow for an increase in the supply of bitcoin tokens. They take the view that this scenario is very unlikely to unfold.

Even though in theory it is possible to increase the Bitcoin supply, in practice, such a change is very unlikely because a large part of the Bitcoin community would strongly oppose such an attempt.

The authors go on to point out that this sort of change in monetary policy may be more likely in a fiat currency protocol.

“Undesirable changes in fiat currency protocols are very common and many times have led to the complete destruction of the value of the fiat currency at hand,” says the article. “It could be argued that, in some ways, the Bitcoin protocol is more robust than many of the existing fiat currency protocols. Only time will tell.”

Bitcoin Is the Most Apparent Application of Blockchain Technology

In addition to offering some basic information on the topic of cryptoassets, the article from the Federal Reserve Bank of St. Louis also provides a general outlook on the future of blockchain technology.

According to Berentsen and Schär, the most apparent application of this technology right now is the use of bitcoin as a new type of asset. The duo see cryptoassets, such as bitcoin, emerging as their own asset class and having the potential to develop into an interesting instrument for investment and diversification.

“Bitcoin itself could over time assume a similar role as gold,” says the article.

The paper also covers applications of blockchain technology in the areas of colored coins, smart contracts and data integrity. The Ethereum network is specifically pointed out as a leader in the area of smart contracts.

Risks of Blockchain Technology

The article from Berentsen and Schär also covers some of the risks associated with cryptoassets.

Minority splits from major cryptoasset networks, such as Bitcoin Cash (Bcash) and Ethereum Classic, are the first risk pointed out in the article, but the downsides of these sorts of spin-off assets are not discussed.

One could argue that these sorts of minority forks create uncertainty around the value of a particular cryptoasset, although this is also the case with the creation of new altcoins more generally.

The paper mentions excessive power consumption as another potential risk of blockchain technology, but Berentsen and Schär do not necessarily agree that proof-of-work mining is wasteful.

“There are those that criticize Bitcoin and assert that a centralized accounting system is more efficient because consensus can be attained without the allocation of massive amounts of computational power,” says the article. “From our perspective, however, the situation is not so clear-cut. Centralized payment systems are also expensive. Besides infrastructure and operating costs, one would have to calculate the explicit and implicit costs of a central bank. Salary costs should be counted among the explicit costs and the possibility of fraud in the currency monopoly among the implicit costs.”

In the past, “Mastering Bitcoin” author Andreas Antonopoulos has argued that the power consumed by Bitcoin miners is “used” rather than “wasted.”

The last risk associated with blockchain technology found in the article is bitcoin’s price volatility. Berentsen and Schär claim that a rigid, predetermined supply of bitcoin is not a desirable monetary policy in the sense that it will not lead to a stable currency.

“If a constant supply of money meets a fluctuating aggregate demand, the result is fluctuating prices,” explains the article. “In government-run fiat currency systems, the central bank aims to adjust the money supply in response to changes in aggregate demand for money in order to stabilize the price level. In particular, the Federal Reserve System has been explicitly founded ‘to provide an elastic currency’ to mitigate the price fluctuations that arise from changes in the aggregate demand for the U.S. dollar. Since such a mechanism is absent in the current Bitcoin protocol, it is very likely that the Bitcoin unit will display much higher short-term price fluctuations than many government-run fiat currency units.”

Credit Suisse Argues Irrational Exuberance Around ICOs Indicates Bitcoin Bubble

creditsuisse.jpg

In a paper written in the fall of 2017 and published on the Social Science Research Network (SSRN) on Friday, January 12, 2018, Credit Suisse’s Dietmar Peetz and Gregory Mall argue that the boom in the initial coin offering (ICO) market is the clearest indicator of a bubble in bitcoin.

Zurich-based Credit Suisse is one of the 40 largest banks in the world with more than $800 billion in total assets, according to Standard & Poor.

According to Peetz and Mall, bitcoin should not be seen as a currency. Instead, the Credit Suisse duo places bitcoin into a new, distinct asset class.

The paper notes that bitcoin’s epic price run, which started in September 2015 and accelerated further in July 2017, is obviously not sustainable over the long term. However, it also adds, “There are arguments for a continuation of this trend for some time.”

The ICO Boom

ICOs were all the rage in 2017, and these new mixtures of seed investing and crowdfunding raised more than $5 billion throughout the year (according to Token Data).

The basic idea with an ICO is that a company or project will create a new token (usually via the ERC-20 standard on Ethereum), which will have some sort of utility on a platform that is either in development or already available.

Whether it makes sense to hold these sorts of digital tokens as investments or speculations is still up for debate.

“These [ICO tokens] often trade at penny-stock prices, experiencing dramatic price increases within hours and are often trading at very low liquidity,” says the paper from Peetz and Mall. “Most of these companies merely offer a so-called ‘white paper,’ basically a business plan that explains which product a company wants to develop in the future and how it wants to market it. Most of these promised projects are praised as having huge potential but are extremely uncertain to be actually developed.”

Having said this, the paper adds that “ICO companies” may continue to raise large sums of money over the short-to-medium term. As supporting evidence for this claim, Peetz and Mall point to the fact that the amounts raised from ICOs increased after the U.S. Securities and Exchange Commission began to caution investors over the summer.

The paper also compares the irrational exuberance around ICOs to the dotcom bubble; however, Peetz and Mall note a key difference in that the dotcom boom at least had companies selling real goods and recording cash flows.

Questions remain as to whether there is any direct correlation between a token’s price and the level of success achieved by a platform connected to the token.

“Most investors acknowledge the bubble situation,” the paper continues. “However, they argue that central bank’s easy money will help the bubble mania to grow bigger and bigger, thus attracting even more investors (speculators) looking for easy profits. They remain bullish because of the Greater Fool Theory.”

Authorities May Prevent Bitcoin from Becoming a Currency

While some people use bitcoin or other cryptocurrencies simply because they have no other option available to them for a particular type of transaction, Peetz and Mall argue that bitcoin is not a transactional currency — mainly due to its inability to act as a reliable unit of account.

Although the paper indicates bitcoin volatility has declined from its peak from 2014 and could fall further through the financialization of the asset, Peetz and Mall also argue a currency cannot work as a clearing mechanism for payments if it cannot be accurately valued.

“The enormously high bitcoin price volatility makes it unsuitable for a reliable day-to-day exchange medium,” says the paper.

In addition to the lack of price stability and time-tested store of value properties in bitcoin, Peetz and Mall also point out a multitude of reasons as to why, in their view, widespread use of the intrinsically-deflationary asset would be detrimental to the overall economy. For this reason, the paper argues authorities may be emboldened to prevent bitcoin from becoming a currency.

“Based on historical precedents, it is not unthinkable that in times of economic or financial crisis, political and regulatory pressure on an unwanted currency would increase, possibly in a similar manner as in the U.S. in 1934, when the Gold Reserve Act of 1934 was ratified, nationalizing all gold and subsequently revaluing it by 69% in U.S. dollar terms,” says the paper.

Of course, Bitcoin was designed to be resistant to government coercion — a sort of BitTorrent for digital, free-market money.

The Bitcoin Bubble Could Continue

So what happens next? According to Peetz and Mall, the bitcoin bubble could continue for some time.

“We believe the most realistic scenario for bitcoin, based on the premise of the currency not being banned by major regulatory agencies, is that it will continue to rise in price in the short to medium term with increased institutional demand prior to the initial hype fading,” says the paper. “At that juncture, bitcoin’s monetization or return prospect realities will begin to set in and, if history is any guide, eventually dominate valuation.”

From Peetz and Mall’s perspectives, the financialization of bitcoin is a symptom of a bubble in money available for investment and the unavailability of productive, real-economy investments.

“Borrowing money for free and having easy access to capital and leverage (for big entities) is the fuel asset bubbles crave,” says the paper. “By aggressively mitigating the effects of the 2008 financial crisis via unparalleled global monetary debasement extending for nearly a decade, central banks have brought us today’s ‘bubbles everywhere’ investment landscape.”

In terms of specific events that could trigger an end to the bitcoin bubble, the paper mentions a crash in the equities market or a potential ban on the possession of bitcoin as two possible scenarios.
