I’ll Take That

Building wealth is the easy part, securing and storing it for use by subsequent generations is very difficult.

Half a millennium ago, a wealthy family needed a private army to secure its land and wealth. If you couldn’t project violence in the defence of your assets, they would be forcibly taken by an opportunistic person.

As civilisations evolved and we entered the age of the nation state, society agreed that a centralised government should have a legal license to kill in order to secure the interests of property owners. Regardless of the economic “ism” a government claims to practice, the goal is the same. Protect a small group of asset holders against the hoard of commoners who might like to improve their lot at the expense of the elites.

Today the richest humans don’t command standing armies, and their holdings include financial and real assets. Stock and bond ownership relies on a central depository to affirm that you indeed are the owner. Government deed offices proclaim a piece of land or real estate is yours.

You are rich as long as the government allows you to be. The trappings of wealth can be taken at a whim. Should your actions upset a powerful state actor, your bank accounts will be frozen, and assets confiscated through the courts.

The recent Saudi corruption drive is case and point. Mohammad bin Salman (MBS), the crown prince of Saudi Arabia, is on a mission to wean the country off of oil. This is harder said than done, especially since the general population only complies because of generous government handouts. To beef up the government coffers, MBS did what all governments do, go after certain rich people.

MBS certainly wouldn’t subject himself to austerity. Last year he purchased a yacht worth over $500 million while at the same time slashing government spending.

Overnight some of the country’s richest members were herded to the Ritz Carlton, and placed under arrest owing to “corruption” charges. The most famous billionaire ensnared was Prince Alwaleed bin Talal. This Price is a world famous investor and has large stakes in some of the biggest tech darlings globally.

After a few days cooped up in the Ritz, MBS presented his chattel with a choice. Liquidate your assets and give the Saudi government up to 70%, or stay locked up. Even if a large percentage of your wealth is held offshore, due to information sharing between governments, MBS likely knows where the biggest nuggets are held. If he doesn’t think you have been forthcoming enough with the true state of your offshore wealth, well the Yemeni front line is awful fun these days.

Bitcoin presents a different way to secure wealth. Instead of trusting a government staffed with capricious humans, holders of Bitcoin trust cryptography and a decentralised network of profit motivated miners.

Bitcoin is less than a decade old, and is still very much an experiment. But if you possess a sum of wealth, it is prudent to diversify the networks used to secure it. Many people believe if they follow the “law”, they will be alright. However, laws change to serve the growth and power of the government writing them.

The government failures in Venezuela and Zimbabwe illustrate that in times of crisis Bitcoin can be used to grease the wheels of commerce. Unfortunately for most, it takes a time of crisis to elucidate the fatal flaws of a particular economic system. Only then will people take concrete actions, which only moments ago, were diametrically opposed to their belief system. At that point it’s too late.

BitMEX vs. CME Futures Guide

Bitcoin is at a watershed moment. The Chicago Mercantile Exchange (CME), the largest exchange globally by notional traded, deemed Bitcoin worthy of a futures contract. The contract will allow investors to speculate on the Bitcoin / USD price without owning Bitcoin. Prior to this contract, derivatives traders were required to own Bitcoin in order to post margin on futures trading platforms such as BitMEX.

Due to the different client bases that BitMEX (retail), and the CME (professional investors) serve, the price discrepancies between two futures contracts with the same underlying will present enormous opportunities to generate arbitrage profits. This guide will walk traders through how to execute such trades.

Contract Specs

Each CME contract is worth 5 Bitcoin (XBT), and quoted in USD. Margin and profit and loss (PNL) are denominated in USD. This is what I refer to as a linear contract structure.

CME XBT Value = 5 XBT * Contracts
CME USD Value = 5 XBT * Price * Contracts

Each BitMEX contract is worth 1 USD of Bitcoin, and quoted in USD. Margin and PNL are denominated in XBT. This is what I refer to as an inverse contract structure.

BitMEX XBT Value = 1/Price * 1 USD * Contracts
BitMEX USD Value = 1 USD * Contracts

The above chart shows the XBT value of each contract. The CME contract has a fixed value in Bitcoin no matter the spot price. The BitMEX contract’s Bitcoin value follows a 1/x function. Technically speaking the BitMEX multiplier is negative, even though in the graph uses a positive multiplier for a better visualisation.

Assume you are long 10,000 contracts at a price of $1,000.

XBT Value = 1/$1,000 * -1 USD * 10,000 = -10 XBT

Now the price falls to $500.

XBT Value = 1/$500 * -1 USD * 10,000 = -20 XBT

At a lower price, the XBT value is a larger negative number.

XBT PNL = -20 XBT - (-10 XBT) = -10 XBT

This means that the value in Bitcoin declines faster as the price falls, and increases slower as the price rises. That is negative gamma, or negative convexity.

The above chart shows the USD value of each contract. The CME contract’s USD value changes in a linear fashion with respect to the spot price. The BitMEX contract’s USD value is fixed at $1 per contract.

CME Contract Specs

Contract Size

The CME contract is much larger in notional terms than BitMEX’s. If the price of Bitcoin is $8,000, one CME contract is worth $40,000. To achieve a similar notional on BitMEX requires 40,000 contracts.

When I touch on spread trades later, the much larger CME notional means that only traders with large amounts of capital can put on these trades. This limiting factor, along with the lower leverage offered by the CME, means most retail traders will be unable to trade the CME product.


The first major difference between the two contracts is the underlying index. The CME settles on the CME CF Bitcoin Reference Rate. This index includes prices from Bitstamp, Gdax, itBit, and Kraken. BitMEX settles on the BitMEX Index that includes Bitstamp and Gdax.

Traders who hold either contract to expiry will need to familiarise themselves with each index, and at a minimum be able to trade on all four exchanges.

Both BitMEX and the CME expire on the last Friday of the contract month. However, BitMEX expires at 12:00 UTC, while the CME expires at 16:00 London Time which is either 16:00 UTC or 15:00 UTC depending on daylight savings. Given that the expiry time differs by only 3 to 4 hours, there is little benefit to adjust the time value when computing relative basis.


Bitcoin is a call option. The more volatile it is, the more valuable the option. Due to an infinite upside, and a capped downside at 0, the trading pressure on the margin comes from longs. That means that market makers who are price neutral will usually be short derivatives. Their propensity to quote an offer depends on how easily it is to purchase spot Bitcoin, and how their short derivative is margined.

As I previously mentioned the BitMEX contract is margined in XBT. That means that shorts can purchase spot Bitcoin and use this as collateral against their BitMEX short. If you buy $1,000 of Bitcoin, deposit the full XBT notional with BitMEX, then short 1,000 BitMEX contracts, you cannot be liquidated if the price rises.

BitMEX shorts, due to the inverse contract structure, are long gamma in XBT terms. That means as the price rises, their unrealised losses increase less quickly. Therefore, BitMEX shorts can use more leverage than they otherwise would if the contract used a linear contract structure.

Contrast that with the CME, which margins the contract in USD. For a market maker who is short, their spot Bitcoin hedge cannot be used as margin at the CME. As the price rises, their Bitcoin is worth more; however those unrealised USD gains cannot be deposited as margin. The CME will demand more USD collateral as the unrealised losses mount.

This makes shorting the CME contract very capital intensive. A priori, I expect the CME contract to trade more expensive than BitMEX. CME shorts need to be compensated via a higher basis for their implicit short volatility position.

The CME intends to list a futures curve out to one year. The backend of the curve, due to a larger time value, will be illiquid when compared to the front months, and will trade at a very high basis.

I will now present two spread trades. Assume that you are a USD based investor.

Spread Trade: Long BitMEX vs. Short CME

Assume the following:

Leverage: 5x / Initial Margin of 20%

Spot = $8,000
BitMEX = $8,000
Contracts = Long 200,000
CME = $10,000
Contracts = Short 6
Spread = $2,000

First compute the XBT and USD exposures.

On BitMEX:
XBT Exposure: 200,000 Long Contracts / $8,000 = +25 XBT
USD Exposure: 200,000 Long Contracts * 1 USD = -$200,000
Margin Requirement: 20% * 25 XBT = 5 XBT
Collateral Currency Exposure vs. USD: +5 XBT / -$40,000 (Valued at the spot price)

XBT Exposure: 6 Short Contracts * 5 XBT = -30 XBT
USD Exposure: 6 Short Contracts * 5 XBT * $10,000 = +$300,000
Margin Requirement: 20% * $300,000 = $60,000
Collateral Currency Exposure vs. USD = 0

Because you are a USD based investor, you must ensure that you do not have XBT/USD risk at any time. Due to the XBT BitMEX margin requirement, you must short an additional 1 CME contact to hedge the 5 XBT margin required on BitMEX.

Margin XBT/USD Price Risk:
BitMEX: +5 XBT / -$40,000
CME: -5 XBT / +$50,000 (Short 1 Contract)
Net: 0 XBT / +$10,000

Due to the CME’s higher basis, we earn carry on the BitMEX XBT collateral.

Spread XBT/USD Price Risk:

BitMEX: +25 XBT / -$200,000 (Long 200,000 Contracts)
CME: -25 XBT / +$250,000 (Short 5 Contracts)
Net: 0 XBT / +$50,000

As predicted, we earn $50,000 PNL from this spread trade. The below table stresses the portfolio on a large up and down move.

$4,000 -25.00 XBT -$100,000 $150,000 $50,000
$8,000 0.00 XBT $0 $50,000 $50,000
$16,000 12.50 XBT $200,000 -$150,000 $50,000

The trade continues to return $50,000 regardless of the price movement. However, this is a leveraged trade, we must post additional margin on either BitMEX or the CME depending on the price move.

The below table summarises what actions must be taken to ensure we meet margin requirements.

Margin Action Currency Needed
Price Falls Buy then deposit XBT on BMEX, sell CME contracts XBT & USD
Price Rises Deposit USD to CME USD

Because we are short gamma on our long BitMEX position, we must post XBT and sell CME contracts to hedge the XBT collateral. Both of these derivatives require additional margin. On the upside, we only need to post additional USD with the CME. Depending on your cost of capital, a prolonged down move without any recovery could become very expensive.

Another issue is the sizing of this trade. Each CME contract is worth 5 XBT. If you wish to remain price neutral on your XBT collateral, a 5 XBT loss needs to be a small % with respect to your trade notional. Otherwise you will always be over and under hedged. The below table illustrates this point.

Entry Price: $8,000
Multiplier: -1 USD (for inverse contracts the multiplier is actually negative)

Contracts XBT Value Down % Move Up % Move
50,000 -6.25 XBT $4,444.44 -44.44% $40,000.00 400.00%
250,000 -31.25 XBT $6,896.55 -13.79% $9,523.81 19.05%
500,000 -62.50 XBT $7,407.41 -7.41% $8,695.65 8.70%
1,000,000 -125.00 XBT $7,692.31 -3.85% $8,333.33 4.17%
2,500,000 -312.50 XBT $7,874.02 -1.57% $8,130.08 1.63%
5,000,000 -625.00 XBT $7,936.51 -0.79% $8,064.52 0.81%

The % Move is a measure of how far the price needs to move up or down to generate a contract value change of 5 XBT. As you can see, go big or go home.

Spread Trade: Short BitMEX vs. Long CME

Assume the following:

Leverage: 5x / Initial Margin of 20%

Spot = $8,000
BitMEX = $10,000
Contracts = Short 250,000
CME = $8,000
Contracts = Long 5
Spread = $2,000

First compute the XBT and USD exposures.

On BitMEX:
XBT Exposure: 250,000 Short Contracts / $10,000 = -25 XBT
USD Exposure: 250,000 Short Contracts * 1 USD = +$250,000
Margin Requirement: 20% * 25 XBT = 5 XBT
Collateral Currency Exposure vs. USD: +5 XBT / -$40,000

In order to hedge the 5 XBT of margin required, sell an additional 50,000 BitMEX contracts.

XBT Exposure: 50,000 Short Contracts / $10,000 = -5 XBT
USD Exposure: 50,000 Short Contracts * 1 USD = +$50,000
Net: 0 XBT / $10,000

XBT Exposure: 5 Long Contracts * 5 XBT = +25 XBT
USD Exposure: 5 Long Contracts * 5 XBT * $8,000 = -$200,000
Margin Requirement: 20% * $200,000 = $40,000
Collateral Currency Exposure vs. USD = 0

Spread XBT/USD Price Risk:
BitMEX: -25 XBT / +$250,000 (Short 250,000 Contracts)
CME: +25 XBT / -$200,000 (Long 5 Contracts)
Net: 0 XBT / +$50,000

As predicted, we earn $50,000 PNL from this spread trade. The below table stresses the portfolio on a large up and down move.

$4,000 37.50 XBT $150,000 -$100,000 $50,000
$8,000 6.25 XBT $50,000 $0 $50,000
$16,000 -9.38 XBT -$150,000 $200,000 $50,000

The trade continues to return $50,000 regardless of the price movement. However, this is a leveraged trade, we must post additional margin on either BitMEX or the CME depending on the price move.

The below table summarises what actions must be taken to ensure we meet margin requirements.

Margin Action Currency Needed
Price Falls Deposit USD to CME USD
Price Rises Buy then deposit XBT on BMEX, sell BMEX contracts XBT

Because you have positive gamma on the short BitMEX position, you will not face a doubling of margin requirements when the price falls. This spread trade is more capital efficient; however, I doubt whether BitMEX will frequently trade more expensive than the CME for reasons described above.

Gap Risk

The CME does not trade over the weekend. Longs or shorts depending on the price action over the weekend, could be insta-rekt when the exchange reopens Sunday night US time.

Interactive Brokers, one of the CME’s clearing members, expressed severe reservations about this product due to the high volatility. They are scared shitless about how to deal with underwater shorts. It is not impossible for Bitcoin to gap up 100% in a matter of hours on positive news. Imagine what will happen when an ETF finally is approved.

BitMEX deals with gap risk via Auto-Deleveraging. The CME at the present moment cannot employ a socialised loss feature. Instead, clearing members must pony up the cash. That is why they are being such scaredy cats.

Depending on your broker, margin requirements for short positions could be extremely unforgiving. This will push CME basis up even further, and make putting on the spread trade described above, even more expensive.

Are You Yellow?

Arbitraging BitMEX vs. the CME requires a high level of trading sophistication and attention to detail. The different margin currencies and policies present many opportunities to transform what is a sure profit into a massive loss.

However, owing its the difficulty, these spread trades will be juicy. For students of markets, this is an arbitrage opportunity of a lifetime. Those who put in the time to perfect these strategies, will profit handsomely.

The Deutsche Bank Connection

Bankers are flocking to the cryptocurrency industry as both principals and employees of related companies, fund managers, and as individual traders. Amid the rush towards this decade’s green financial pastures, one office of one bank stands out, Deutsche Bank Hong Kong.

Deutsche Bank’s foray into investment banking began with its acquisition of Bankers Trust. The firm then proceeded to ditch its conservative German roots, and import the biggest swingers in the industry. A clique of Merrill Lynch bankers were brought in. Their ring leader was Anshu Jain.

The culture was cowboy. My Hong Kong summer internship interviews in 2007 illustrates this point.

The first round of interviews was in Philadelphia. In my second 2-on-1 interview I met the man who’s team I would intern on that summer. I had just returned from my semester abroad in Hong Kong. He asked me why I loved Hong Kong, and I said I loved clubbing. I then rattled of a list of my favourite establishments. He would later tell me, that’s what sealed the deal for me in his mind.

That night I took the whole Deutsche contingent to my favorite dingy Philly late night EDM club. It got messy.

In 2007, financiers thought they were gods. Hong Kong has never regained the energy I felt that summer. I interned on the Equity Derivatives sales desk. HR nicknamed this desk the Snake Pit, because of the aggressive personalities that worked there.

The 2008 graduate training program in London featured similar aggressiveness. Deutsche offered an all expense paid trip to London for three months for all incoming graduates. The Japanese grads were the most intense. One grad got so drunk, and vomited so hard, he was hospitalised with a broken rib.

That is a taste of how the youngins were trained at Deutsche. The firm fostered an aggressive culture focused on partying hard, and making money. Unlike more demure banks, no one at Deutsche was shy as to why they were in the game. Making money was the goal, and no one was censured for being too flashy.

As the financial services industry entered a secular decline after the 2008 GFC, Deutsche people scattered to the wind. Deutsche lied to the German regulators about the value of its assets in an effort to avoid becoming recapitalised by the taxpayers. In hind side, that was the dumbest move ever. Their competing American banks gladly took TARP funds, paid huge bonus, and repaired their balance sheets. Deutsche limped along, and is one of the worst performing banks since the crisis.

The Deutsche Hong Kong reunion was ignited by Bitcoin. For some reason, this particular office is very well represented in the Bitcoin industry. The individuals I will list all went through the graduate training program, and our Deutsche stints all overlapped.

在不赞成Winklevoss ETF COIN的同时,美国证券交易委员会(SEC)表示,缺乏具有流动性而又受监管的衍生品市场是一个他们担心的因素。如果CME不失败的活,它们将为ETF铺平道路。美国证券交易委员会的派对是顺着大型金融机构的音乐节奏来的。如果CME从衍生产品中获得巨额利润,那么资产管理公司就会想通过一个上市的ETF来分一杯羹。

All Hail The CME

Due to overbearing and counterproductive financial regulations, innovation is often rewarded with heavy fines and loss of licenses. An institution with billions of dollars of revenue at stake cannot take the regulatory and reputational risk dealing with Bitcoin unless someone else does it first.

Enter, LedgerX. For over four years, the firm pestered the CFTC to allow them to clear Bitcoin settled futures and options. The hard work paid off this fall when their markets launched. Less than two weeks later, the CME announced they too would join the club. The CBOE technically was the first legacy exchange to announce the impending launch of a USD settled Bitcoin futures contract; however, the CBOE will go live 2Q2018 and the CME plans to launch theirs by year end.

The only reason why some large financial institutions (FI) participate in the digital currency ecosystem is they cannot ignore an asset class that went from $0 to almost $200 billion in value in under a decade. Large FIs are severely constrained in their ability to deploy large amounts of capital due to counterparty risk on exchanges not compliant with their specific jurisdictional overseers. An exchange who they can already trade with, the CME, that offers Bitcoin trading products is exactly what they need to seriously get involved.

Custody Risk

A USD-settled Bitcoin futures contract is perfect for large traders who cannot or will not custody Bitcoin. This futures contract gives them exactly what they desire, a product that pays them fiat currency to speculate on a crypto currency.

From the CME’s perspective, they also absolve themselves of the risk of losing customer Bitcoin. This product requires almost zero technical innovation on their part.


The BitMEX XBTUSD swap is the most liquid Bitcoin / USD trading product globally. XBTUSD trades 5x – 10x more volume than the underlying index constituents, GDAX and Bitstamp, combined. XBTUSD’s daily trading turnover routinely exceeds $1 billion, and approaches $2 billion.

The CME index will include itbit and Kraken as well. For market makers who must hedge flow on the underlying exchanges, two seriously liquid derivative contracts will increase the volatility in the spot markets. It will also place immense strain on the spot exchanges’ infrastructure. Can these four exchanges stand up to the likes of Citadel submitting, amending, and cancelling thousands of orders per minute? Time will tell, but the CME is about to get a crash course in Bitcoin.

These issues probably influenced the way in which their index was constructed. The index methodology is overly complex in an attempt to deal with the forecasted liquidity and technological issues the leading spot exchanges face.

BitMEX takes a more laissez-faire attitude about the Bitcoin markets than the CME can afford. Every financial reporter will be watching for any misstep, and the headlines will come hard and fast highlighting any issues.

Market Fragmentation

The Bitcoin markets are highly fragmented due to different regulatory regimes and cultural differences between traders from different domiciles. The type of trader who can trade with the CME cannot trade with many of the exchanges where the reference pricing occurs.

This presents a trading opportunity of a lifetime for arbitrage funds who can straddle the regulated and unregulated exchanges, and who can trade across multiple jurisdictions. The divergences will become more acute as large positions are placed on CME and CBOE products.

Will the regulated derivatives follow or lead vs. the cowboy trading occurring in North Asia? From a market microstructure perspective, this will be a very interesting experiment.

ETF Anyone?

In the disapproval of the Winklevoss ETF COIN, the SEC stated that the absence of a liquid regulated derivatives market concerned them. If the CME doesn’t face plant, this will pave the way for the ETF. The SEC dances to the beat of large FIs. If the CME is reaping immense profits from a derivative, asset managers will want in on the racket via a listed ETF.

Much like LedgerX, the Winklevii might be bested by a large ETF manager like Blackrock or Vanguard, who now has the regulatory cover to apply for their own Bitcoin ETF. Blackrock vs. the Winklevii; who has more capacity to provide push jobs for ex-SEC staffers?

While futures will allow wealthy individual traders and large FIs to comfortably trade Bitcoin, an ETF that appeals to retail investors globally will completely change the paradigm. Starting next year, expect more noise about an ETF approval emanating from the SEC.

Slow then Fast

I did not expect institutional take-up of Bitcoin to grow this quickly. There is too much money being made by startups in the space for large FIs not to get involved. As more and more of the regulatory and repetitional risk is removed, institutions will continue to increase their involvement and exposure.


仓位已经开始反应出热烈的交易情况。在上一期通讯中,我强调了以SegWit2x 硬分叉为主的BitMEX期货交易策略。三周后,期货基准显示交易员在硬分叉前持有的大量仓位。在这篇文章中,我将研究进阶交易需要考虑的因素和仓位还原的策略。






Max % Premium PA Max % Outright Discount
XBTM17 122.30% -2.28%
XBTU17 32.38% -5.62%
XBTZ17 42.47% -7.17%






这一次,大部分精明的交易员都透过卖空XBTZ17基准来达到仓位还原的目的。基准点 = 未来价格 – 现货价格。任何时候基准持平或是为正数的时候,他们便会增加空头头寸。然而,一但硬分叉结束大量的XBTZ17仓位必须被平仓。




我在德意志银行工作的时候,有一位法国期权交易员每每在市场高开高走的时候,都会发出了一个高频刺耳的“卖空挤压”嘶吼声。 XBTZ17是一个卖空挤压的绝佳市场,我相信追求利润最大化的矿工们会触发更高的价格上扬。








  1. 买入现货比特币。
  2. 以很大的折扣价格买入XBTZ17期货。
  3. 在硬分叉截止日前一刻停止发送支持“纽约协议”的信号。
  4. 享受通过保证金和期货消灭卖空方的乐趣。



  1. 如果您是以做空为主(卖空XBTZ17及以现货价格买入),那么在获利的情况下还原交易仓位。
  2. 在基准是负值的情况下买入(买入XBTZ17及以现货价格卖空比特币)。
  3. 如果您的风险偏好大,那么在XBTZ17基准是负值的情况下单向买入。

The Miner Short Squeeze

Positioning has begun in earnest. In the last newsletter, I highlighted BitMEX futures trading strategies centered around the SegWit2x hardfork. Three weeks hence, the futures basis indicates aggressive positioning by traders heading into the hard fork. In this post, I will examine advanced trading considerations and unwind strategies.

XBTZ17 In Context

Bitcoin is up over 7x since January this year. Given this aggressive bull market, futures should trade in contango. Longs must pay a substantial amount of interest to entice shorts to position themselves against the trend.

The below charts list the annualised % premium for the XBTM17 (June), XBTU17 (September), and XBTZ17 (December) Bitcoin / USD futures contracts.

Each quarterly contract existed during a price rally. However, the Bitcoin Cash and upcoming SegWit2x fork dampened the premium for XBTU17 and XBTZ17 respectively.

Max % Premium PA Max % Outright Discount
XBTM17 122.30% -2.28%
XBTU17 32.38% -5.62%
XBTZ17 42.47% -7.17%

The above chart illustrates that XBTM17, which experienced no hard fork during its existence, had the highest premium and discount. XBTU17 experienced its max discount during the Bitcoin Cash hard fork.

XBTZ17 is already pricing in the SegWit2x hard fork. If the max discount has already exceeded XBTU17’s, then we can expect a substantially larger discount directly preceding the SegWit2x hard fork.

The discount is a combination reflecting traders’ fears of a disorderly hard fork, and traders selling XBTZ17 vs. buying spot to create SegWit2x coins with no Bitcoin price risk. Due to the heightened risk and publicity surrounding the SegWit2x hard fork, the discount could reach up to 15% pre-fork.

The Unwind

This time around most savvy traders are short XBTZ17 basis. Basis = Future Price – Spot Price. Any time the basis trades flat to positive, they increase their short position. However, once the fork is over large percentage of the XBTZ17 open interest must close their positions.

Many traders might close their XBTZ17 short at a mega discount pre-fork, then switch to long basis to play the relief rally. But if everyone is the same way, many will give up profits during the unwind. Additionally, bullish speculators will jump in pre-fork to take naked longs anticipating a sharp rally after the fork occurs.


During my time at Deutsche Bank there was a certain French options trader that emitted a high pitched squeaky yell of “Short Squeeze” any time the market gapped higher into the close. The XBTZ17 market is primed for a short squeeze, and I believe profit maximising miners could initiate an even sharper rally higher.

The miners signed the New York Agreement (NYA) in an effort to save face and acquiesce to activating SegWit, while at the same time securing larger blocks in the future. The NYA headed off a chain split due to UASF, but Bitcoin Cash was launched as a direct result.

Bitcoin Cash has an 8MB block size without SegWit. As it stands now, there is no need for SegWit2x Bitcoin. However, the majority of miners continue to signal for the NYA.

Signaling for the NYA costs them nothing, and it does not mean they actually will support the hard fork with hash power.

What would happen to the market if at the last minute all the large miners stopped signalling for NYA and the hard fork didn’t happen? You know the answer, Pump City. The other consequence is a violent resetting of XBTZ17 basis. All those who went short basis to collect the B2X dividend would rush to unwind their trades at the same time.

BitMEX will not credit B2X coins. Therefore, XBTZ17 shorts will remove margin from BitMEX the day before the fork and deposit on an exchange that will credit B2X. That means the leveraged used by shorts will increase further putting their positions at risk of liquidation during a short squeeze.

If I were a profit maximising miner here is what I would do:

  1. Buy Bitcoin Spot
  2. Buy XBTZ17 futures at a large discount.
  3. Shortly before the hard fork deadline, stop signalling for NYA.
  4. Bask in the glory of the annihilation of shorts on margin and futures.

If you believe this thought experiment might become reality here is what you should do:

  1. If you are short basis (short XBTZ17 vs. long spot), unwind that trade at a profit.
  2. Go long basis while it is negative (long XBTZ17 vs. short spot).
  3. If your risk appetite is large, go naked long XBTZ17 at a negative basis.

SegWit2x Bitcoin Is Not a Dividend

B2X is different than BCH in that B2X supporters do not want their coin to be an altcoin. It will either become Bitcoin or nothing.That is why they refuse to implement replay protection which allows exchanges to safely support B2X.

In the event exchanges delay the listing of the B2X by even a day, by the time you theoretically could sell B2X, it might be worthless because it failed at supplanting legacy Bitcoin.

If you went short XBTZ17 basis at a flat to positive level, you are in the money. Closing the trade early and earning the expected dividend is prudent due to the fundamental differences between B2X and BCH.



在这段时间内,中国禁止了三个世界上最大的交易平台。 “纽约协议”签署方进一步推动了SegWit2x硬分叉。大银行机构的负责人甚至称比特币为一个骗局。



转载自 Investopedia:

“M2 is a measure of the money supply that includes all elements of M1 as well as “near money.” M1 includes cash and checking deposits, while near money refers to savings deposits, money market securities, mutual funds and other time deposits.”

“M2是用来衡量货币供应量的,其包括M1的所有存量以及“近货币”。 M1包括现金和支票户口的存款,而近货币是指储蓄存款,货币市场证券,共同基金和其他定期存款。”







但是,当市场拒绝就可负担利率的负债做续贷时,债务必须被偿还。其中一个理论提到,过度负债的政府可以透过提高债务货币对应真正货币(如黄金)的价格来降低债务/ M2杠杆比率。保罗·布罗德斯基(Paul Brodsky)在 “Apropos of Everything I, II and III” 中提出了一个很好的论点,说明中央银行为什么要把债务货币相对黄金给淘汰。我不相信中央银行会把比特币加到其资产池中。更可能发生的情况是,对通货膨胀较敏感的投资者会把手上债务货币投向相对便宜及真实的数字货币工具,如比特币。



如果比特币是数字黄金,那在理论上它的价格可以达到黄金相对于政府债务总额的相同价格比例。这意味着比特币价格可达到 461,333 美元,或近80倍的涨幅。
