Bitcoin ETF Buzz Offers Short Term Opportunity

If you follow Bitcoin at all, then you know that its value is spiking. It has already surpassed a massive spike on Thanksgiving night 2013, and it has just surpassed the cost of an ounce of gold. [continue below image]

Like any commodity, the exchange value of Bitcoin is driven by supply and demand. But, unlike most commodities, including the US Dollar, the Euro or even gold, the eventual supply is capped. It is a mathematical certainty. Yet, demand is affected by many factors: Adoption as a payment instrument, early signs that it is being considered as a reserve currency, fascination by Geeks and early adopters and its use as a preferred tool by some criminals.

But chief among reasons for acquiring Bitcoin is speculation. Whether it is buy-and-hold or day trading, speculators still outnumber those who use Bitcoin to settle debts or to buy and sell other products and services. (Earlier this week, I argued that speculation is responsible for 85% of demand and of transactions—but that’s another story).

It’s a bit ironic that speculation—in the early days of a new market—retards organic adoption. It contributes to uncertainty and volatility, and it reduces the fraction available to the markets that make it both useful and liquid. Yet, in free markets, speculation is a necessary and critical antecedent to adoption.

This week, short term speculators have an unusually keen opportunity to profit, especially if they know how to buy a ‘put’ or sell a ‘call’ (i.e. to leverage a bet for or against the direction of Bitcoin, without actually acquiring any). For example, you can bet that an exchange-traded stock will fall, because there is a market for puts & calls. But it’s not as easy to bet against commodities that are not yet listed for options trading.

I am not going to give advice in this article. I am not a licensed investment professional and although I am bullish on long term, organic adoption of Bitcoin, I really don’t have an opinion on the current news or the short term prospects for a pull back. But, if you have an opinion on a current news event, then there is an immediate opportunity for you to make (or lose) a significantly leveraged sum in the next few days…

SEC and ETFs (Alphabet soup of investment banks)

Next weekend, on Saturday March 11, the United States Securities and Exchange Commission (SEC) will approve or deny an application for the first regulated, recognized and significantly backed Bitcoin Exchange Traded Fund (ETF). Why is this significant? Because most investments are not hand picked by individual investors. Investors choose the level of risk or diversification that seems reasonable for their life stage and then leave stock-picking decisions to a formula, a market sector basket, or a fund manager. That is, invest or park their money in a fund rather than betting on Space-X, PayPal or the local electric company. [continue below image]

If approved, an ETF potentially adds massive new demand for a commodity, by offering a financial instrument than can be subscribed by the vast fraction of funds, investors, pensioners and speculators who prefer to leave asset management to an organization, outside broker or formula.

The first ETF application is created and backed by the Winkelvoss Twins. They were Olympic rowers, but found fame & fortune by contracting Marc Zuckerberg to create an early design for Facebook. If their application is approved, a dozen more investment banks, brokers and hedge funds are standing by to jump in with both feet.

This morning, Cointelegraph put the odds that the ETF will be approved at 50%. Some analysts place the chances even higher. But consider that Bitcoin has already spiked dramatically in the past few weeks. The excitement is already reflected in the price. So, where is the opportunity?

The opportunity, as with any speculative decision, is in the dissonance between your research and hunch compared with the overall market expectation reflected in the current price. So, for example, if Bitcoin is accepted as the basis for an ETF (and if it continues to grow in more fundamental adoption), the current price is actually remarkably low. Under these assumptions, it hasn’t even begun its period of rapid ascent. Perhaps more obviously (and even more short-term), if you believe that an ETF will be blocked by regulators, then the recent rise is likely to be reversed quickly, at least in the minutes after the March 11 decision is announced.

So how can you profit from your belief that a commodity will drop in value? I leave that to your personal investment knowledge and research or your financial advisor. My purpose is not to advise, nor even to teach about puts and calls. It is to point out that a few people will win or lose a lot of real money this coming weekend—at least on paper. And it all hinges on whether they can correctly predict the outcome of a regulatory decision process.

Again, Bitcoin is a very limited commodity, There are only 15.2 million coins today, and there will never be more than 21 million coins. This does not present an obstacle to adoption, because the coins can be sliced smaller and smaller as needed. In a noteworthy demonstration of ‘good deflation’, there will always be enough units for everyone—even if the entire world adopts it for every transaction under the sun.

Antonopolous Clarifies Blockchain’s Profound Leap

I use to hate it when my dad insisted that I read something longer than 2 paragraphs. (Something related to his interests, but not to my school work, his career or our family). That’s because it shouldn’t require a 30 minute read to determine if it piques my interest, as it does his.

But I am asking Lifeboat readers to invest 37 minutes in the video linked below. Even if you give it just 5 minutes, it will provide sufficient motive for you to stick around until the end. [continue below video]

I want you view it because we are on the threshold of something bigger than many people realize. Bitcoin and the blockchain is not just a new currency or a way of distributing books among network users. We are becoming involved with a radical experiment in applied game theory that is shockingly simple, but nascent. Opportunities abound, and the individuals who recognize those opportunities or learn to exploit them will benefit themselves as they benefit the global community. Because it is so radical (and because it clashes with deeply ingrained beliefs about authority, control mechanisms, democracy and money), it seems complex and risky—but it’s really not.

I am a Bitcoin educator and columnist. I have taught college seminars in Bitcoin and I will be keynote speaker at the 2017 Digital Currency Summit in Johannesburg. I design online courses for the most popular cryptocurrency self-learning groups. But Antonopolous runs circles around me. He is a Bitcoin evangelist extraordinaire. All of his presentations are superb, but this one provides context. It conveys an understanding that Bitcoin novices and professionals equally appreciate. It answers questions the viewer hadn’t asked, but would have.

There are hundreds of videos and PowerPoint presentations that explain how Bitcoin works. But they rarely provide context. Few of them convey why it is such an important development and why it has overtaken biotech & pharmaceuticals as the focus of VCs . Few can explain why an ethereal Bitcoin (a unit that you cannot hold) has just surpassed the value of a unit of gold. And few people realize that volatility has been abating as the increase in value and adoption is surging.

As you watch Antonopolous, you are certain to think about things that you did not previously know—or at least, that you did not reflect upon. My purpose in asking you to view it, is not to sell you on Bitcoin or the blockchain, but to provide the context that may help you to code, consult, write articles, teach, begin trading, start saving, and more.

What Fraction of Bitcoin Value is Driven by Speculators?

At Quora, I occasionally play, “Ask the expert”. Several hundred of my Quora answers are linked here. Today, I was asked “How much of Bitcoin’s value is driven by speculation”. This is my answer…

This is a great question! While the value of any commodity is determined by supply and demand, speculation is one component of demand. Another is the unique utility value inherent in a product or process. This is sometimes called ‘intrinsic value’.

It’s ironic that when a high fraction of value is driven by speculation, short-term value becomes volatile and long-term value becomes less certain—and less likely to produce returns for those same speculators.

Editor’s Note: In the past few weeks, a significant spike in Bitcoin’s value and trading volume relates to a pending regulatory decision expected at the end of next week. This activity is certainly driven by speculation. But for this article, I am considering periods in which the demands of individual events are less clear.

The value of Bitcoin is influenced by:

  • Day traders who buy and churn
  • Long-term speculators who buy and hold. This includes me.
  • Criminals who hope that cryptocurrency transactions can be more easily hidden than government backed currencies
  • Early adopters who use Bitcoin as a payment instrument or to send money
  • Vendors who accept the coin in exchange for products and services
  • Vendors who retain a fraction of revenue in Bitcoin (rather than exchanging to Fiat). To avoid a round trip exchange, they seek to purchase materials or pay staff with the Bitcoin they earned.

Here’s the rub: Bitcoin will not become a store of value unto itself (i.e. a currency), and it will not gain a significant fraction of the payment instrument market until the transaction volume of the first to user categories in the above list are overtaken by the the ones further down. Likewise, Bitcoin will not enter its biggest growth spurt until the last two items swamps the others as the largest motive for acceptance and use.

Put another way: Long term value must ultimately be driven by organic adoption from actual users (people who are buying and spending Bitcoin on other things.

In another article, I expand on the sequence of events that must take place before Bitcoin grows into its potential. But make no mistake. These things will happen. In tribute to the brilliance of Satoshi, the dominoes are already falling.

In response to the question, I estimate that at the beginning of 2017, 85% of Bitcoin value is still driven by speculators. I have not analyzed wallet holding periods compared against the addresses of known vendors. Furthermore, it would be difficult to understand the relationship between the number of speculative transactions and the overall effect on value. Therefore, my figure is more of a WAG than an calculated estimate. But it’s an educated WAG.

The fraction of speculative transactions will drop significantly in the coming months—even as late speculators jump on board. That’s because uptake from consumers and businesses is already taking off. The series of reactions that lead toward ubiquitous, utilitarian applications has begun. Bitcoin’s value will ultimately be driven by use as a payment instrument and in commerce.

Because it is a pure supply-demand instrument, Bitcoin will eventually be recognized as currency itself. That is, it needn’t be backed by precious metal, pegged convertibility or a redemption promise. When that happens, you will no longer ask about Bitcoin’s value. That would be a circular question, since its value will be intrinsic. Instead, you will wonder about the value of the US dollar, the Euro and the Yen.

As a growing fraction of groceries, gasoline and computers that you buy are quoted in BTC, you will begin to think of it as a rock, rather than a moving target. One day in the future, there will be a sudden spike or drop in the exchange rate with your national currency. At that time, you won’t ask “What happened to Bitcoin today? Why did it rise in value by 5% this morning?” Instead, you will wonder “What happened to the US dollar today? Why did it drop in value by 5%?”

MIT is working on 3 BIG Blockchain Ideas

MIT has never stood stand still in the presence of change and opportunity. Their Media Lab Currency Initiative is at the forefront of Blockchain and Bitcoin research. With the fracture of the founding core team, MIT stands to become the universal hub for research and development.

The initiative now has a team of 22 people and at least
seven ongoing research projects, and it nurtures three startups that use cryptocurrencies and the underlying technology in a variety of ways. Blockchain research now sits alongside transparent robots that eat real-world fish, solar nebula research, and other imaginative, futuristic projects in progress at the university.

The initiative has already funded the work of bitcoin protocol developers and has supported research, going far beyond bitcoin—even partnering with Ripple Labs and developing enterprise data projects.

Now, the MIT Media Lab Digital Currency Initiative is working on 3 big Blockchain ideas:

  1. Shattering online ‘echo chambers’
  2. Improving blockchain privacy
  3. Building central bank currencies

The DCI is led by former White House advisor and research director Neha Narula. Read about the three BIG blockchain projects at CoinDesk.

Distributed Objective Consensus: Beyond POW & POS

At the heart of Bitcoin or any Blockchain ledger is a distributed consensus mechanism. It’s a lot like voting. A large and diverse deliberative community validates each, individual user transaction, ownership stake or vote.

But a distributed consensus mechanism is only effective and faithful if the community is impartial. To be impartial, voters must be fairly separated. That is, there must be no collusion enabled by concentration or hidden collaboration. They must be separated from the buyer and seller; they must be separated from the big stakeholders; and they must be separated from each other. Without believable and measurable separation, all sorts of problems ensue. One problem that has made news in the Bitcoin word is the geographical concentration of miners and mining pools.

A distributed or decentralized transaction validation is typically achieved based on Proof-of-Work (POW) or Proof-of-Stake (POS). [explain]. But in practice, these methodologies exhibit subtle problems…

The problem is that Proof-of-Work can waste an enormous amount of energy and both techniques result in a concentration of power (either by geography or by special interest) — rather than a fair, distributed consensus.

In a quasi-formal paper, C.V. Alkan describes a fresh approach to Blockchain consensus. that he calls Distributed Objective Consensus. As you try to absorb his mechanism, you encounter concepts of Sybil attacks, minting inequality, the “nothing-at-stake” problem, punishment schemes and heartbeat transactions. Could Alkan’s distributed consensus mechanism be too complex for the public to understand or use?…

While I have a concern that time stamps and parent-child schemes may degrade user anonymity, the complexity doesn’t concern me. Alkan’s paper is a technical proposal for magic under the covers. Properly implemented, a buyer and seller (and even a miner) needn’t fully understand the science. The user interface to their wallet or financial statement would certainly be shielded from the underlying mechanics.

Put another way: You would not expect a user to understand the mechanism any more than an airline passenger understands the combustion process inside a jet engine. They only want to know:

• Does it work? • Is it safe? • Is it cost effective? • Will I get there on time?

So will Alkan’s Decentralized Objective Consensus solve the resource and concentration problems that creep into POW and POS? Perhaps. At first glance, his technical presentation appears promising. I will return to explore the impact on privacy and anonymity, which is my personal hot button. It is a critical component for long term success of any coin transaction system built on distributed consensus. That is, forensic access and analysis of a wallet or transaction audit trail must be impossible without the consent and participation of at least one party to a transaction.

Blockchain Scalability: Proof-of-Work vs BFT Replication

Research can seem bland to us laypersons. But, Marko Vukolić shares many of my research interests and he exceeds my academic credentials (with just enough overlap for me to understand his work). So, in my opinion, his writing is anything but bland…

Vukolić started his career as a post-doc intern at IBM in Zurich Switzerland. After a teaching stint as assistant professor at Eurecom and visiting professor at ETH Zurich, he rejoined the IBM research staff in both cloud computing infrastructure and the Blockchain Group.*

As a researcher and academic, Vukolić is a rising star in consensus-based mechanisms and low latency replicated state machines. At Institut Mines-Télécom in Paris, he wrote papers and participated in research projects on fault tolerance, scalability, cloud computing and distributed trust mechanisms.

Now, at IBM Zurich, Vukolić has published a superior analysis addressing the first and biggest elephant in the Bitcoin ballroom, Each elephant addresses an urgent need:

  • Scalability & throughput
  • Incentivize (as mining reward withers)
  • Grow & diversify governance & geographic influence
  • Anonymize transactions to protect privacy
  • Recognize & preserve ownership

Regarding the first elephant, scalability, Bitcoin urgently needs to grow its Blockchain dynamics into something that is living and manageable. To that end, Vukolić refers to a transaction bookkeeping mechanism that works as a “fabric”. That is, it does not require every miner to access the history-of-the-world and append each transaction onto the same chain in serial fashion. Rather than growing an ever bigger blockchain—with ever bigger computers—we need a more 3D approach that uses relational databases in a multi-threaded, transactional environment, while still preserving the distributed, p2p trust mechanisms of the original blockchain.

While clearly technical, it is a good read, even for lay enthusiasts. It directly relates to one of the elephants in the room.

I have pasted Marko’s Abstract below. The full paper is 10½ pages (14 with references).

Bitcoin cryptocurrency demonstrated the utility of global consensus across thousands of nodes, changing the world of digital transactions forever. In the early days of Bitcoin, the performance of its probabilistic proof-of-work (PoW) based consensus fabric, also known as blockchain, was not a major issue. Bitcoin became a success story, despite its consensus latencies on the order of an hour and the theoretical peak throughput of only up to 7 transactions per second.

The situation today is radically different and the poor performance scalability of early PoW blockchains no longer makes sense. Specifically, the trend of modern cryptocurrency platforms, such as Ethereum, is to support execution of arbitrary distributed applications on blockchain fabric, needing much better performance. This approach, however, makes cryptocurrency platforms step away from their original purpose and enter the domain of database-replication protocols, notably, the classical state-machine replication, and in particular its Byzantine fault-tolerant (BFT) variants.

In this paper, we contrast PoW-based blockchains to those based on BFT state machine replication, focusing on their scalability limits. We also discuss recent proposals to overcoming these scalability limits and outline key outstanding open problems in the quest for the “ultimate” blockchain fabric(s). Keywords: Bitcoin, blockchain, Byzantine fault tolerance, consensus, proof-of-work, scalability, state machine replication

* Like Marko, Blockchains, Cloud computing, and Privacy are, also my primary reserach interests, (GMTA!). But, I cede the rigorous, academic credentials to Marko.

† BFT = Byzantine Fault Tolerant consensus protocols

Getting your First Bitcoin; Choosing a Wallet

There are at least four ways to acquire Bitcoin and three ways to store it…

Acquire Bitcoin: You can trade Bitcoin in person, accept it as a vendor, mine it, or buy on an exchange.

Store Bitcoin: You can keep your Bitcoin in an online/cloud service (typically, one that is connected to your exchange account), keep it on your own PC or phone, or even print it out and store it on a piece of paper. Like a physical coin, the piece of paper has value. It can be placed in your lock box or under your mattress.

Let’s look at the market for Bitcoin Wallets (all of these are free), and then we shall talk about Bitcoin exchange services. This includes my personal recommendation for the typical consumer or coin enthusiast…

1. Choosing a Wallet

You can start your search for a wallet on this page at Bitcoin.org. Use the drop down tabs to refine your search by platform: Mobile, Desktop, Hardware gadget or Web. Don’t overlook the web option. For many users, the wallet (and VAULT) included with an online exchange account is all you need.

Each wallet platform is further distinguished by operating system. For example, you can find a smartphone wallet for Android, Apple, Windows Mobile or Blackberry. Some popular apps are listed under more than one OS or platform.

When you click on any of the app logos, you will see a checklist of five key traits, according to reviewers at the Bitcoin Foundation:

  • Control over your money
  • Simplified validation
  • Basic transparency
  • Secure environment
  • Weak privacy

These are not necessarily critical traits/features. It depends on your needs and preferences. For example, everyone wants good privacy and security. But not everyone wants to control their private keys. That places the risk of loss, backup and/or the burden of inheritance issues on you, rather than a standardized recovery process. The feature comparison simply helps you to begin your own comparison and evaluation.

For Android users, my personal recommendation is Bitcoin Wallet by Andreas Schildbach (the logo is a tilted orange ‘B’). It is simple, secure, well maintained and very popular. (iPhone users: See my my suggestion in the recommendations, below).

2. Portable –vs– Online

Despite the simplicity and low cost of spending or sending Bitcoin between individuals and vendors, getting your first Bitcoin can be confusing, complex and even risky. For this reason, I suggest that Newbies open an account at a very established and trustworthy exchange.

In the near future, this will include most big banks. But for now, the safest and most reputable exchange is Coinbase in San Francisco. They are also the one with the highest level of regulatory compliance. Bitstamp of Slovenia and Great Britain is a close second. In my opinion, using either of these organizations as a currency exchange or a secure place to park your digital currency is a safe bet.

Both of these exchanges include a cloud wallet service that—when used properly—is safe and secure. But, because Bitcoin is still in its infancy, you will need to learn about sweeping funds into a ‘vault’ (to better protect against hacking) and you should also learn about portable backups and multi-sig (to protect your assets, in the event of forgetfulness, death or incapacitation).

With either type of wallet—device storage or online with an exchange—I recommend that you install and play with a portable wallet on your phone, just to get the hang of a few basic functions: Display wallet address for incoming money, Send money, Request money (i.e. send an invoice), and Pay with the QR-camera feature. All wallets serve these basic and critical needs.

Recommendations:

  • Coinbase is a most reputable exchange for buying/selling & storing Bitcoin
  • Bitcoin Wallet by Andreas Schildbach is an excellent choice for portable, secure storage. This app is available for Android phones only. Apple iPhone users may wish to try Bitcoin Wallet by Blockchain. I have not reviewed it. It has a slightly less friendly user interface but it is stable and very popular.

Quantum Foundation Combines Bitcoin and Ethereum to Create Qtum

Nice try; no faith it will succeed long term with QC.

Singapore-based Quantum Foundation announced that it is working on a new project called Qtum, which combines the technology of both bitcoin and ethereum to facilitate blockchain technology adoption for corporations. Qtum is an open-source blockchain project that aims to build smart contract functionalities that can be implemented at an enterprise level.

The initial financial backing of $1 million by several industry leaders is a testament to the validity of the technology that the Qtum project is creating but also demonstrates full faith in its team of developers. Early-stage angel investors in the project include ethereum co-founder Anthony Di Iorio, Fenbushi partner Bo Shen, and OKCoin CEO Star Xu, among others. The Qtum project also intends to launch its native cryptocurrency to support the project through a crowd sale to raise further funds.

Can Bitcoin Flourish with a Capped Supply?

The answer may be counter-intuitive: Not only can Bitcoin be widely adopted under a supply cap, its trust and integrity are a direct result of a provably limited supply. As a result, it will flourish because it is capped.

Everyone Can Own and Trade a Limited Commodity, IF…

…if it is both measurable and divisible. Bitcoin has a capped supply just as gold has a capped supply. Although both assets will be mined for some time into the future, there is only so much that will ever be uncovered. Thereafter, the total pie cannot grow.

But the transaction units will continue to grow as needed, because the pie is divisible into very, very tiny units:

There will eventually be 21 million BTC and each coin is divisible into 108 units. This yields (21 million * 100 million), or 21 trillion exchangeable units. And, it can be divided further by consensus.

As Bitcoin is adopted—whether as a simple payment instrument, an investment asset or even as national currencies around the world—each unit of the limited supply simply rises in value. If thought of as a currency, with a value established by supply & demand, it leads to a deflationary economy.

But, Isn’t Deflation Bad for the Economy?

It’s common to associate deflation with economic ills. One need only glance back at the the last century to conclude that deflation coincides with wars, joblessness, recession and a crippling concentration of wealth. Perhaps, just as bad, the tools used to pull a nation out of deflation often force governments to cherry pick beneficiaries of stimulus spending.

But it is important to note that deflation plays no role in causing these things. On the contrary, it is an effect rather than a cause… In fact, when a supply cap is introduced as a designed control input for monetary policy, all sorts of good things follow. I address these in various answers at Quora. Dig in:

Bitcoin Arbitrage: Can you profit?

At Quora, I occasionally play, “Ask the expert”. Today, I was asked if the difference between quotes at various Bitcoin exchanges presents a profit opportunity.

In addition to my answer, one other cryptocurrency enthusiast offered pithy, one-line response: He said “Buy local, sell internationally and pocket the difference!” I tend to believe the opposite is more likely to generate profit: Buy internationally and sell locally. But, I am getting ahead of myself. Here is my answer [co-published at Quora]…

Question:
A Bitcoin exchange in my country quotes a different rate than
international markets. Can I profit from the price difference?

Answer:
Buying and selling a commodity with the intention of profiting from the difference in price in various markets, regions or exchanges is called arbitrage. Typically, the item must be widely traded and fungible. Although it can be a tangible item (one that must be delivered or stored, like gold, oil, frozen orange juice or soy beans), arbitrage is more practical when applied to an ‘item of account’, such as foreign currency, equity shares, stock futures, or Bitcoin.

With this in mind, Bitcoin qualifies as a fungible item of account. If you see a different price at vaious exchanges (or if you believe that you can source personal sales at a higher price than the market spot price), then you have found an opportunity for arbitrage. But hold on! It is not so easy…

  1. The arbitrage opportunity is often illusory. For example, the cost difference that you observe in market quotes may be overshadowed by the bid/ask spread or by fees, which can be both fixed and a percentage.
  2. The arbitrage opportunity is transient. It is there for a few seconds and then it vanishes in the next quote. For this reason, successful arbitrage players must be very adept at day-trade techniques. To avoid massive risks, you need up-to-the-second quotes, fast trading tools, and the ability to simultaneously freeze your purchase and sale price.
  3. Trust is never golden! Even with these tools and promises, when a commodity begins to move in either direction, you will find that a buyer or seller often finds a way to renege on the agreed price. These are not random events…When a trading partner abandons a transaction, it always work against you.
  4. Some exchanges (and even some national regulatory agencies) prohibit rapid and repeated trading. This may be to discourage speculation or it may be designed as a circuit-breaker (a mechanism to avert the cascade effect that sometimes results from pre-programmed trades). These halts on quick trades can wipe out your gains, or worse. They can turn your investment into a horrible mess.
  5. Some big exchanges have built-in arbitrage mechanisms that quickly adjust prices and even buy and sell on their own account to keep their limit order books in sync. They are on the front lines and you aren’t! This fact, alone, should suggest give you pause. The opportunities for an outsider are severely limited by these ‘inside’, self-adjusting trades.
  6. Other legal risks: If the transaction is later deemed to be illegal in the jurisdiction of any party, your exchange accounts may be frozen or your privileges revoked. Unlike p2p Bitcoin transactions, exchange transactions can be reversed. Again, these legal snafus will always work against you. In fact, sometimes, they were pre-planned scams from the start!
  7. Finally , there are sometimes good reasons for different prices in different markets. For example, national and local regulations may burden to the consumer cost for an item, or the seller may be required to pay a fee or tax to some authority or regulatory agency. If you dodge these costs, you may be violating laws and subject to penalties or punishment. You may even put your customer at risk.

I am neither an arbitrage player nor a day trader. These are just a few warning bells that come to mind when I think about such activity. You can be sure that this list of risks only scratches the surface. Bitcoin is remarkably fluid and many people flaunt regulations. For this reason, I am confident that opportunities for profitable arbitrage are rare and very tiny (small gain for a big risk).

Have I scared you away from Bitcoin arbitrage? If not, proceed with extreme caution and don’t bet the family ranch! Once you have some experience, come back and post feedback below. I have dabbled in options arbitrage, but never with Bitcoin or any currency. Since I don’t have first-hand experience, your feedback will be appreciated.
