“The highest correlation to long-term success, is Github commits”

Published / by breakingbitcoin

Someone said to me this week that the highest correlation to long-term success, is Github commits. A research paper done a while back showed that developer activity was the highest correlation to long-term success. Not marketing, not hype, not liquidity or whatever. Go to Coingecko and sort by “Developer” and it has got an interesting picture

Good interview with Willy Woo (@woonomic on Twitter).

“From the minting of the first coin until today, the struggle has never abated”

Published / by breakingbitcoin

From Jack Weatherford’s thorough, delightful, and easy to read book History of Money:

The great struggle of history has been for the control over money. It is almost tautological to affirm that to control the production and distribution of money is to control the wealth, resources, and people of the world. Over time, competitors have aligned themselves into various factions, institutions, governments, banks, guilds, corporations, religious orders, and great families; but from the minting of the first coin until today, the struggle has never abated for more than a brief respite of a century or two.

Weatherford, by the way, is quite an accomplished writer. I became a fan while reading his book “Genghis Khan and the Making of the Modern World”.

I recently shared 19 highlights from the book on my blog.

Very good paper analyzing Bitcoin and other blockchains for things like velocity and privacy

Published / by breakingbitcoin

Here’s the full paper. And some of my notes / excerpts below:

  • Use of multi-sig in a public blockchain reduces privacy not only of user, but of other users as well
  • Use of mixers is a poor privacy measure and potential attack vector, as shown with Bitcoin and Dash
  • A good chunk of Bitcoin blockchain transactions still carry no fee, and often reflect a direct relationship between miner and transaction generator
  • Bitcoin transaction fees still amount to only 20% of miner reward (but growing)
  • Bitcoin velocity is much lower than expected (this, IMO, was the most interesting part):
    • the velocity of Bitcoin works out to 1.4 per month averaged over the period January 2016–July 2017, compared to 5.4 with the naive metric. Our revised estimate is not only much lower but also much more stable over time.
  • only a small percentage of bitcoins are used for activities other than investment and speculation, although that fraction has been gradually increasing over the past year

“Crypto-currencies exhibit a size effect like stocks”

Published / by breakingbitcoin / 1 Comment on “Crypto-currencies exhibit a size effect like stocks”

From the perspective of an investor into the alternative asset class of crypto-currencies, we document that returns of crypto-currencies are weakly correlated both in their cross-section as well as with established assets, and thus interesting investments for diversifying portfolios. An investment strategy based on the CRypto-currency IndeX (CRIX) bears lower risk than any single of the most liquid crypto-currencies. Furthermore, we show that crypto-currencies exhibit a size effect like stocks.

Pretty good paper on cryptocurrency investment factors and price drivers [link]. Note, though, that the researchers seem to have some sort of relationship with the CRIX.

Size effect = smaller coins tend to perform better.

I haven’t published much lately, and that’s unlikely to change. Not even sure if I’ll continue the newsletter. I find myself losing interest in writing about and analyzing the space during such a secular – and some may say overheated – bull market. What advice can I give you, other than “don’t sell” (unless it’s small amounts of profit taking) and “don’t daytrade to excess”?

The long-term prospects of cryptocurrencies, cryptoassets, and token economies are brighter than ever. $1T is squarely within sight.

A guy who knows what he’s talking about talks about Bitcoin

Published / by breakingbitcoin

Written by security researcher Dan Kaminsky over 4 years ago, still very relevant and insightful today (the best kind of content, imo). Wired article. Some snippets:

Bitcoin’s a dollar bill, with a teleporter built in. We can just poke in a few coordinates and poof, off it goes, with the ease of posting to some forum somewhere.

There are a small number of choke points, which someday may be asked to honor these thefts. Will the currency translators accept the money? Will the mining pools? It’s really an open question.

Bitcoin miners could very well be doing useful work, same as the gold miners. That the work is pointless misses the point. Diamonds, for example, represent little more than millions of years of earthly labor making dull black coal into a shiny clear crystal.

Fighting over what’s “fiat” and what’s “real” is silly. It’s all fiat. Gold isn’t conscious; all value is belief. What’s fiat is who can change the supply and how. Nobody can just declare the existence of one million new bitcoin and start trading on it.

It would take a massive, society-rending effort against general purpose computing to really keep Bitcoin down.

Bitcoin is the first example of a new form of life…

Published / by breakingbitcoin

…It lives and breathes on the internet. It lives because it can pay people to keep it alive. It lives because it performs a useful service that people will pay it to perform. It lives because anyone, anywhere, can run a copy of its code. It lives because all the running copies are constantly talking to each other. It lives because if any one copy is corrupted it is discarded, quickly and without any fuss or muss. It lives because it is radically transparent: anyone can see its code and see exactly what it does.

From Ralph Merkle on DAOs, Democracy, and Governance (yes, the guy who invented Merkle trees).

The quote echoes Kevin Kelly’s theme of technology-as-life-form in What Technology Wants.

Notes from in-depth University of Cambridge study on the cryptocurrency ecosystem

Published / by breakingbitcoin

Great report. Highly recommend reading the full PDF (116 pages but goes quick). In a nutshell:

First, the user adoption of various cryptocurrencies has really taken off, with billions in market cap and millions of wallets estimated to have been ‘active’ in 2016. Second, the cryptocurrency industry is both globalised and localised, with borderless exchange operations, as well as geographically clustered mining activities. Third, the industry is becoming more fluid, as the lines between exchanges and wallets are increasingly ‘blurred’ and a multitude of cryptocurrencies, not just bitcoin, are now supported by a growing ecosystem, fulfilling an array of functions. Fourth, issues of security and regulatory compliance are likely to remain prevalent for years to come.

Here are my notes and takeaways:

  • crypto is worth $27B = Airbnb
  • 3M to 6M active crypto wallets
  • 2K+ people working full-time in the industry
  • crypto exchanges (eg, Kraken, BitFlyer) employ the most people
  • 70% of large miners say they have “high influence” on protocol development
  • report divides industry players into #1 exchanges, #2 wallets, #3 payments, and #4 mining with growing levels of crossover
  • companies surveyed have 21 full-time employees on average (still early days)
  • “A 2016 joint report from Coinbase and ARK Invest estimates that 54% of Coinbase users use bitcoin strictly as an investment”
  • “Non-monetary use of Bitcoin has also increased. For example, the use of the OP_RETURN feature in the bitcoin scripting language (frequently used for embedding metadata in bitcoin transactions, for enabling e.g., time-stamping services and overlay networks) has increased roughly 100x since January 2015”
  • four currencies (USD, EUR, JPY and CNY) dominate trading
  • impression is that we’re still in very early days of proper security and auditing; as an investor, remember to turn on 2FA and only keep small amounts on exchanges
  • “The average business (B2B) payment has a transaction size of $1,878, whereas P2P transfers ($351) have higher average transaction sizes than consumer (C2B) payments ($210)”

3 important charts from the report

…Bitcoin dominates but Ethereum has shown impressive growth

…trading in Chinese RMB dropped precipitously after the government crackdown on margin accounts and no-fee trading

…Mining is now a multi-billion dollar industry!

“A large percentage of currency…is used precisely to hide transactions”

Published / by breakingbitcoin

“There is nothing, however, in standard theories of money that requires transactions to be anonymous from tax-or law-enforcement authorities. And yet there is a significant body of evidence that a large percentage of currency in most countries, generally well over 50%, is used precisely to hide transactions.”

From Kenneth Rogoff’s “Costs and Benefits to Phasing Out Paper Currency.”

Notes from Grayscale’s Ethereum Classic (ETC) investment thesis

Published / by breakingbitcoin

I read through the investment thesis PDF yesterday and wanted to share some relevant notes. I sold more than 90% of my ETC a month after the hard fork, so I hold a negligible amount relative to my overall crypto portfolio and don’t have plans to increase my ETC position. I am very bullish on ETH even after its recent price run-up.

Notes:

  • concentrates on two aspects: store of value (ETC as silver / platinum to BTC’s gold) and enabling a payments and smart contracts layer for the IoT
  • liked this line: “Ethereum was designed to be the next iteration of operating systems like Apple iOS or Microsoft Windows, embedded with the enhanced capabilities of blockchain technology.”
  • they note, and I didn’t realize, that less than 6% of all ETH outstanding voted on the hard fork issue
  • ETC strengths (relative to ETH):
    • truly trustless protocol (ie no hard fork)
    • no PoS risk, will wait until ETH implements it first and then assess
    • hard cap on ETC supply; currently 89M outstanding, will never exceed 230M (likely closer to 210M)
    • more decentralized development process unlike Ethereum which is driven by Vitalik and the Ethereum Foundation
  • ETC risks:
    • the Ethereum Foundation sold 90% of their ETC but still hold a substantial amount
    • the DAO hacker still holds 4% of all ETC in a known wallet address

Interesting report and while I personally won’t invest in ETC, was good to understand Barry and Grayscale’s perspective.
