MobileCoin Cracks The Privacy Code: Marrying Crypto with P2P Messaging

Signal and MobileCoin join forces.

News today on our portfolio company MobileCoin: Read Signal’s blog post here and the Wired article here.

In the last ten years, two parallel trends have emerged: Mobile P2P and group messaging, and crypto. While many have tried to introduce crypto-based P2P and e-commerce payments to popular messaging apps, nobody has cracked the code.

The marriage between mobile P2P and crypto is a powerful proposition: Bring together global communication with global payments. What could arise from this union? Fast P2P payments. Secure e-commerce. Fast & reasonably priced remittances. One possibility is realizing the crypto trope of “banking the unbanked”: In places where financial systems are weak but social messaging apps are mainstream, crypto-based P2P has the potential to create sudden and rapid financial connectivity.

We backed MobileCoin as investors because MobileCoin is the first real attempt to merge these two worlds. The protocol’s unique focus on privacy and transaction speed matches the instantaneous delivery model for popular apps worldwide. Mobilecoin will live inside these mainstream messaging apps, starting with the most cryptographically secure: Signal. As the first massively popular mobile messaging app to include MobileCoin for P2P and e-commerce payments, Signal is the best possible validation of MobileCoin’s privacy, security, and speed, just as Signal set the bar for end-to-end encryption within mobile messaging apps prior.

MobileCoin makes it easy for messaging apps to offer digital payments without compromising user privacy. By integrating a MobileCoin wallet, a mobile app can send transactions without maintaining a copy of the blockchain or sharing keys with a remote server. Transactions are final within just a few seconds, and all transactions are kept private.

MobileCoin takes a defense-in-depth approach to user privacy. This begins with established technologies like ring signatures, one-time addresses, and RingCT. They’ve added a suite of cutting-edge privacy tech on top of this existing foundation, from secure enclaves and information management designed to delete the final traces of Cryptonote on the blockchain. In MobileCoin, even if malicious attackers manage to compromise a node, they can never access user keys or data.

With this privacy layer at the heart of the protocol, MobileCoin also introduces microservices designed to enable mobile usage. This starts with MobileCoin Fog, a service run by apps to help find user transactions, check balances, and build new transactions, all without downloading the ledger (a prohibitively expensive task for mobile devices).

This is where cryptography gives users a feeling of security that no existing messaging app can provide: While Fog will be run by app providers, user privacy is entrusted to MobileCoin technology, not to the service provider. In other words, users don’t need to trust the company; they instead put their trust into the integrity of the MobileCoin Foundation’s open-source software.

We believe MobileCoin is the beginning of crypto’s marriage with mobile messaging apps. We hope to see far more experiments in the next year, as crypto marches us into a new era where users sleep at night with their faith in cryptography.

Toward Credibly Neutral Derivatives: Announcing Our Investment Into Vega

Like a prison tattoo, March 12 2020 is branded into every crypto trader’s mind. Nobody can forget the terror of that fated candle. No trader will ever escape the disbelief of watching a derivatives market that developed over years break within minutes.

Crypto desperately needs credibly neutral derivatives. A year from this PTSD-inducing moment of market history and not much has changed. Put aside the fact that we still don’t know what happened on that day the majority of derivatives volume is still executed off-chain in the opaque land of the centralized exchange. 

The market needs decentralized derivatives that can match the centralized experience, a place where traders can take on leverage, move capital efficiently and hedge risk without worrying about something breaking or someone squeezing them behind a curtain.

We are thrilled to announce our investment into Vega Protocol, which we believe will be the most important player in this emerging world of decentralized derivatives. We are excited to co-lead the round with Cumberland DRW, one of our closest trading partners. The round brings together a strong group of trading firms and DeFi investors including ParaFi Capital, Coinbase Ventures, CMT Digital, Signum Capital, DeFi Alliance, CMS Holdings, Three Commas, SevenX Ventures, GSR, ZeePrime Capital and more.

Vega marries the ingenuity of DeFi with the hard-won wisdom of order books. It unites the AMM with the CLOB, breaking the dichotomy between active and passive liquidity. In Vega, market makers are owner-operators, incentivized to seed markets; while passive LPs provide liquidity to their strategies. The team complements this novel economic design with a heavy focus on risk management and capital efficiency, pioneering solutions to challenges like frontrunning, multi-chain collateral and scalability. 

A snapshot of the Vega exchange interface.

We are stoked to get behind a team of world-class entrepreneurs, engineers, academics and traders and will publish more on our investment in the coming months.

Resurrecting The Saver: Walking Tall With Anchor

The DeFi Standard For Crypto-Native Fixed Income

The macro storm of quantitative easing and record low interest rates has depressed yields in traditional finance beyond measure. Anchor is the first protocol in Decentralized Finance (DeFi) designed to capture the growth of the cryptocurrency ecosystem to offer savers fixed income yield.

The Anchor Protocol is a money market built on the Terra blockchain, leveraging the only stream of unlevered, reliable yield in cryptocurrency: Proof-of-Stake (PoS) block rewards. Anchor synthesises DeFi yield with PoS rewards, creating a fundamentally new economic primitive – the Anchor Rate – providing lenders a stable rate of return. In time, we believe the Anchor Rate will become the reference rate for DeFi investment – a Decentralized Funds Rate – and eventually the gold standard for passive income on the blockchain.

Anchor launches with LUNA as the initial primary collateral asset for borrowers, with a roadmap to integrate other PoS assets including DOT, ATOM and SOL, and decentralize ownership of the ANC governance token through a liquidity mining program.


Arrington XRP Capital Joins The DeFi Alliance

We are proud to announce Arrington XRP Capital has joined the DeFi Alliance. The DeFi Alliance is an incubator launched by a notable group of Chicago-based trading firms in early 2020, including CMT Digital, Volt Capital, Jump Capital, and DRW.

Today, the Alliance has evolved into the primary hub for DeFi startup incubation and mentoring. When I founded TechCrunch, I witnessed first hand the rapid rise and popularity of Y Combinator, and the immense value that these kinds of organizations provide to startups. We hope the DeFi Alliance grows to have a similar impact.

At Arrington XRP Capital, we have been investing behind the scenes with projects in the DeFi Alliance program, and welcome the Alliance’s support as our portfolio companies go to market. Stay tuned.

The Standard For Synthetic Assets: Mirror

The emerging world of synthetic assets is one of DeFi’s most powerful bridges into traditional financial markets. With the backdrop of macro change accelerated by COVID-19, we argue that synthetic assets can create a gravitational pull on capital, as investor appetite moves deeper into the risk spectrum. Notably, we examine the growing international demand for US equities and the challenges faced by investors in the existing e-brokerage model.

This context leads us into the primary focus of the report, Mirror: a new protocol for synthetic asset creation. Mirror synthesizes the primary innovations of DeFi – including Automated Market Makers (AMMs), oracles, stablecoins and liquidity mining – to enable permissionless minting and trading of traditional assets. Mirror is uniquely positioned as a capital efficient system using stablecoins, reducing collateralization requirements to only 150%, a vast improvement over comparable systems which are typically collateralized upwards of 300-400%.

Mirror will launch with support for a select number of US equities, and will decentralize ownership of its native governance token MIR via a community-first distribution strategy.


Bitcoin Risk and The Once-In-Cycle Trade

Risk management frameworks are rare in the world of Bitcoin. For overexposed market participants, the asset’s volatility invites extremes in investor psychology at a pace unlike any other market. Somehow, Bitcoin continues to dance between two distinct worlds: today on the brink of a death spiral and tomorrow the future of currency destined for world reserve status.

Arguments for Bitcoin exposure stress its long run outperformance, yet often fail to address the concerns of the non crypto-native investor. Since inception, Bitcoin has outperformed virtually every other asset class. This outperformance is undeniable, point-blank. Still, traditional portfolio managers stick to their skeptical guns, cautious of a one-sided focus on returns when the answer to double digit drawdown is HODL.

In this piece, we attempt to build a framework for risk-adjusted Bitcoin investing. Our goal is to filter out the noise of investor psychology and find the nuances of Bitcoin risk and reward at different stages of the macro cycle. We do this through a simple rolling Sharpe Ratio that analyzes Bitcoin risk-adjusted returns over time.

Ultimately, we conclude that timing matters: while the individual investor may be satisfied with long-run outperformance, Bitcoin’s macro cycles urge further nuance. We find that historically, the trade following the Halving represented the most attractive risk-adjusted opportunity. As the next Halving is just around the corner, we briefly speculate on why this was the case.

Looking beyond returns: the Sharpe Ratio

For the professional money manager, Bitcoin’s systematic risks are daunting. How can a conservative PM embrace Bitcoin as part of a diversified portfolio given the frequency and severity of its drawdowns? Investors with personal savings and unconstrained time horizons seek comfort in the story of Bitcoin’s long-run outperformance. This is not enough for newcomers with fiduciary responsibility. For the traditional PM, every market risk represents redemption, career and reputational risk; and for this reason, we need a more serious understanding of Bitcoin’s relationship with drawdown.

Even if over 90% of all Bitcoin days are profitable, individual paths to profitability range from months (buying December 2018’s bottom) to years (buying the 2014 global top). This illustrates the concept of path dependence: while long term Bitcoin returns are disproportionately skewed to the upside, timing matters. Much like a call option, Bitcoin risk-adjusted returns rapidly decay or improve depending on market timing.

We look to the Sharpe Ratio to analyse the path dependence of Bitcoin returns. The Sharpe Ratio is a simple yet powerful metric, measuring the ratio of excess returns to excess return volatility:

If we view volatility as a placeholder for risk, the Sharpe Ratio measures how much reward is generated per unit risk. A highly volatile portfolio would thus have a low Sharpe Ratio if returns were not extraordinary, and vice versa. A Sharpe Ratio of 1 is considered the baseline standard for investment performance.

Animal spirits, why a long-run Sharpe Ratio doesn’t cut it

Over any rolling four-year period, Bitcoin’s Sharpe Ratio historically outperformed virtually every other asset class. If an investor had held for at least four years during any point in Bitcoin’s history, they would have demonstrated superior risk-adjusted returns relative to almost all other investment opportunities.

This still falls short for most non crypto-native investors. Thinking about Bitcoin’s Sharpe Ratio over four year intervals may be correct in theory, but it is limited in practice. In reality, markets are governed by animal spirits – the swings of fear and greed – and most investors are more likely to enter the market after periods of non-linear growth. Many new entrants are thus destined to enter mid to late-cycle, fated to experience grueling drawdowns after buying local or even global highs. The assumption that investors can and will HODL underwater positions for multiple years is unfeasible, especially with the prospect of underperformance relative to other asset classes. The financial and emotional burden of drawdown will likely lead many to capitulate their positions before they are able to realise an entire four year cycle.

Given the path dependence of returns, the long term Sharpe Ratio fails to adequately capture Bitcoin risk.

The one year forward looking Sharpe Ratio

Instead of four-year intervals, we search for the optimal entry within a macro cycle. To do this, we employ a one year forward looking Sharpe Ratio.

Figure 1 calculates the Bitcoin Sharpe Ratio at any point in time looking forward one year. This metric is inherently forward looking, describing the Sharpe Ratio at any point in time based on future data. It is thus a lagging, descriptive (rather than predictive) variable. We select the one year period as it is approximately the time required to capture the brunt of a Bitcoin bull or bear market.

Figure 1: Bitcoin’s one year forward looking Sharpe Ratio.

Oscillating around a value of 1, the one year forward looking Sharpe Ratio peaks at the beginning of Bitcoin’s price inception, the 2012 Halving and several months following the 2016 Halving. After these three periods, we find an interesting dynamic at play: aggressive Sharpe Ratio decay from a high of 3 (spectacular) to a low of −1 (abysmal).

Further, examining the 1-4 year forward looking Sharpe Ratio for Bitcoin from the Halvings (see Table 1), we find a similar effect:

  • Exposure to Bitcoin for 1 year after the 2012 Halving nets a Sharpe Ratio of over 3, and holding for an additional 3 years degrades this to approximately 1. From a spectacular investment to a “good” investment.
  • Exposure to Bitcoin for 1 year after the 2016 Halving nets a Sharpe Ratio of over 2, and holding for an additional 3 years degrades this to less than 1. From a great investment to a sub-standard investment.
Table 1: Forward looking Sharpe Ratio at 1-4 year intervals following the Halvings.

How important is market timing when managing Bitcoin risk?

Analysing Sharpe Ratio decay gives us a powerful risk framework. Not all Bitcoin investments are made equal: Bitcoin acquired at different points in a macro cycle should be treated differently as part of a diversified portfolio. To illustrate this concept, consider the idea of “time-to-profitability” (TTP) demonstrated in Figure 2:

  • Bitcoin acquired at the 2011 high has a ≈2 year TTP
  • Bitcoin acquired at the late 2013 high has a ≈3 year TTP
  • Bitcoin acquired at the 2017 high is yet to achieve profitability.
Figure 2: Bitcoin’s days to profitability.

Not only were investors who purchased Bitcoin at these highs faced with absolute drawdown, they were also faced with relative underperformance against worldwide equity indices (and possibly other asset classes). Bitcoin can be an excellent tool within a diversified portfolio, but most professional investors cannot simply buy and HODL for extremely long periods of time if they are likely to face both absolute and relative underperformance.

The legacy wisdom of financial markets sometimes cautions investors against market timing, captured by the dominance of indexing strategies and the underwhelming reputation of the modern hedge fund. Whatever the merits of this argument in traditional markets, we find a fundamentally different heuristic exists for Bitcoin.

This doesn’t mean that other strategies like buy and HODL are not valid. It is simply to say that for investors focused on managing risk, timing matters.

A once-in-cycle trade, but don’t forget to expect the unexpected

The above analysis leads us to conclude that, historically, the best risk-adjusted entry existed at or within several months following a Bitcoin Halving. This heuristic is based on historical data and is not a trading guideline. The market may prove our analysis entirely wrong for future Halvings. Our goal is to build frameworks based on history but there are no certainties in markets, least of all in Bitcoin. We present this Halving idea with its obvious limitations in mind.

While the crypto market’s focus on long-run outperformance might convince some pioneering and brave money managers, it won’t convince the drawdown-conscious. However, Bitcoin doesn’t need to be perfect to make its way into the world of traditional investing. Even today, the argument shouldn’t be to HODL and hope, but to think about Bitcoin with a nuanced vision for risk. This post-Halving window, when combined with hedging practices like protective puts or a managed stop loss, help build a case that, on a risk-adjusted basis, Bitcoin may outperform other asset classes.

If Bitcoin springs to new highs within the next several years, the reality is that investors will eventually demand exposure. Ironically, as these requests pile in mid to late-cycle, money managers will be faced with a dicey dilemma: remain on zero as Bitcoin makes weekly headlines or enter a drawdown-prone asset at local or absolute highs. Rather than enter as greed floods the market, the post-Halving window may grant investors an early buffer to incorporate Bitcoin into their broader macro strategy.

Are there fundamentals that explain this finding?

Why does the Halving trade demonstrate superior risk-adjusted returns? We can only speculate, but PlanB’s Stock-To-Flow model provides some insight. If we slightly modify PlanB’s model to calculate “flow” as a rolling sum of new Bitcoin minted over the past year (as opposed to the past day), as per Figure 3, we find that the market tops as the S2F ratio begins to level off. This makes intuitive sense: assuming demand stays constant, the supply reduction means there is less float for buyers to absorb, shifting prices upwards over time until a new equilibrium is reached.

This could also explain why, in addition to the two Halvings, the early years following Bitcoin’s inception also represented a very strong risk-adjusted entry. With a low initial float (starting from S = 0 at launch), the 1-year S2F ratio grew at a rate comparable to the post-Halving windows.

We speculate that these periods of rising S2F following the Halving are the only times where there is a fundamental driver (outside of speculative demand) for Bitcoin price: a real shift in the supply and demand curve. Thus, it is possible that our conclusion about the Halving trade is not random, but a result of S2F fundamentals.

Figure 3: Bitcoin Stock-To-(1-Year)-Flow


In this piece, we have shown that long term metrics such as the four year Sharpe Ratio are inadequate at capturing the real risks of Bitcoin investing. Extreme swings of the market result in rapid Sharpe Ratio decay and make timing critical for the drawdown-conscious investor. The post-Halving window may represent a rare time to add high expectancy, low-downside Bitcoin exposure. We hope that our analysis builds a case that the Halving is not merely a speculative catalyst, but a fundamental macro driver that may present crypto-natives and newcomers alike with a powerful risk-adjusted opportunity.

Crypto Wars: A New Hope

Nakamoto.com, a new initiative founded by crypto investor and entrepreneur Balaji Srinivasan, launched quietly last Friday evening. There was no initial press coverage, just a series of tweets to announce the purpose of the new website and link to some of the initial posts.

.A battle quickly erupted on Crypto Twitter about the use of the Satoshi name for a website that includes authors that are not approved by the high priests of the bitcoin fundamentalist sect.

Regardless, Balaji’s initial post was a rallying cry for the future of crypto, and Bitcoin’s rightful place as the flag of a new wave of technology.

I think this is a much needed resource to help heal some of the senseless fighting in crypto today. Many outsiders see a lot of chaos in crypto, insane infighting that appears meaningless to newcomers but quickly demands that someone take a side. Pro BTC or anti-BTC (just saying “Pro-Bitcoin leads many to ask “WHAT Bitcoin do you mean!!!). Pro this alt coin or that one.

Healthy debates are wonderful and happen every day in crypto. But unhealthy debates, spectacularly dramatic, drown out the good conversations. Nakamoto appears to be an effort to bring together the more reasonable people in crypto to celebrate what’s good about the technology.

“That’s why we’re launching Nakamoto. We want to create a venue for quality technical, philosophical, and cultural writing that is of general interest to the crypto community as a whole, for beginner and expert alike.”
