You heard about this bitcoin thing? Every bitcoin story must include an image of a physical bitcoin. Note: Physical bitcoin coins do not really exist. 1,000 threshold for the first time on Jan. But the Bitcoin story has so much more to it than just headline-grabbing pricing swings.
It incorporates technology, currency, math, economics and social dynamics. It’s multifaceted, highly technical and still very much evolving. This explainer is meant to clarify some of the fundamental concepts and provide answers to some basic bitcoin questions. It’s actually a little more complicated than that.
Simply put, bitcoin is a digital currency. No bills to print or coins to mint. When someone sends a bitcoin to someone else, the network records that transaction, and all of the others made over a certain period of time, in a “block. Computers running special software — the “miners” — inscribe these transactions in a gigantic digital ledger. When a new hash is generated, it’s placed at the end of the blockchain, which is then publicly updated and propagated. For his or her trouble, the miner currently gets 12. Note that the amount of awarded bitcoins decreases over time.
THE FUTURE OF MONEY
What determines the value of a bitcoin? Ultimately, the value of a bitcoin is determined by what people will pay for it. In this way, there’s a similarity to how stocks are priced. The protocol established by Satoshi Nakamoto dictates that only 21 million bitcoins can ever be mined — about 12 million have been mined so far — so there is a limited supply, like with gold and other precious metals, but no real intrinsic value. Without a government or central authority at the helm, controlling supply, “value” is totally open to interpretation.
Bitcoin has made Satoshi Nakamoto a billionaire many times over, at least on paper. It’s minted plenty of millionaires among the technological pioneers, investors and early bitcoin miners. If you’re willing to assume the risk associated with owning bitcoin, there is an increasing number of digital currency exchanges like Coinmama, CEX, Kraken and Coinbase — the largest and most established of them — where you can buy, sell and store bitcoins. Getting started is about as complicated as setting up a Paypal account.
Once your account is funded, which usually takes a few days, you can then exchange traditional currency for bitcoin. What can I do with bitcoin? You can use bitcoin to buy things from more than 100,000 merchants, though still few major ones. Or you can just hang on to it. Short, qualified answer: Yes, for now, as long as — like any currency — you don’t do illegal things with it.
Legal and regulatory hazards aside, as both an investment and currency, bitcoin is very risky. When you wake up in the morning, you know pretty precisely how much a dollar can buy. The financial value of a bitcoin, however, is highly volatile and may swing widely from day to day and even hour to hour. This anonymity can be appealing, especially with companies and marketers increasingly tracking our every purchase, but it also comes with drawbacks. You can never be certain who is selling you bitcoin or buying them from you.
The bitcoin subreddit is rife with individuals’ stories and even established exchanges are targets. There are few avenues for pursuing refunds, challenging a transaction or recovering such losses. Once a transaction hits the blockchain, it’s final. Coinbase has been tested by a massive rise in interest in bitcoin.
Bitmain Nears 51% Of Total Bitcoin Network Hashrate
OK, so what about — wait, there are more risks? Because bitcoin is so new and decentralized, there is plenty of murkiness and many unknowns. Even the technical rules for mining are still evolving and up for debate. The IRS views bitcoins as property, not currency. Then there’s the fundamental question of whether you should trust a particular exchange. Even Coinbase, the most established of them all has struggled to keep up with demand, plagued by site outages, scaling issues and customer service complaints.
Even if it’s venture-backed, every bitcoin player today is by definition a startup and comes with all of the associated risks. Now I sort of understand bitcoin. Though they share a common digital ancestry, each now has its own individual blockchain with slightly different protocols. For what it’s worth, bitcoin miners are sticking with 1MB blocks, Bitcoin Cash uses 8MB blocks.
Forking is almost assured to happen again in the future. More than a thousand, with more sprouting up every day. Aside from bitcoin, which is the real progenitor of them all, other well-known alternative currencies include Ethereum, Ripple and Litecoin. A quick and dirty introduction to trading cryptocurrency.

The worst thing that could happen is no one buys your coin. The best thing that happens is that someone buys your coin and you can then convert the coin into real money, retire, and act like you are super-wise thought leader with oodles of entrepreneurial and investing experience.
Basically none of the feel-good goals about lowering remittance fees or increasing financial inclusion promoted in previous years by enthusiasts have really materialized. Oh, but transaction fees for Bitcoin are at all-time highs, that’s a real milestone right? I must be, there is no other explanation! I’m sure you’ll be on their bingo card at some point too. 6 But that’s because they censor your freedom loving transactions! So what’s the interim solution during this era of higher fees? Need to send a bitcoin payment to someone?
You know how supermarkets used to hold items on layaway? They still do, but it’s not as common to use, hence why you googled the term. You know, just like you do with your favorite local bartender. Fun fact: the original title of the Satoshi whitepaper was, Bitcoin: a peer-to-peer electronic layaway system. For example, the ad above was promoted far and wide by Bitcoin enthusiasts, including Andreas Antonopoulos who still tries to throw sand in Western Union’s eye.

Many enthusiasts fail to incorporate in their cartoonish models: that the remittance and cross border payment markets have a set of inflexible costs that have led the price structure to look the way it does today, and a portion of those costs, like compliance, have nothing to do with the costs of transacting. Rather than repeat myself, check out the break down I provided on the same Western Union example back in 2014. Or better yet, look at the frequently updated post from Save on Send, who has the best analysis bar none on the topic. I even stopped aggregating numbers 18 months ago because fewer companies were making usage numbers public: it’s hard to write about specific trends when that info disappears. Due to a lack of relevant animated gifs, a full break down on the topic wouldn’t fit in this article.
If you haven’t seen the Godfather trilogy, it’s worth doing so during or after the holiday break. This year we have collectively witnessed the techbro re-enactment of Godfather: Part 3 with the seeming legitimization of online bucket shops and dodgy casinos, aka cryptocurrency intermediaries, you wouldn’t talk about in polite company. Not all medium-to-large coin holders are the adopters you now see wearing suits on television talk shows. In late 2013, during the second bull run of that year, there were frequent reddit threads about how mainland Chinese could use Bitcoin to route around censorship and all the other common civil libertarian tropes. On December 5th, 2013, the People’s Bank of China and four other ministries issued guidance which restricted activities that domestic banks could do with cryptocurrencies, thereby putting spot exchanges in a bit of a bind, causing panic and subsequently a market crash.
As I detailed in a previous post, earlier in the autumn, several state organs in China finally closed down the spot exchanges, which in retrospect, was probably a good decision because of the enormous amounts of scams and deception going on while no one in the community was policing itself. For example, Reuters did an investigation into some of the mainland exchanges this past September, prior to the closure of the spot exchanges. It’s unclear how much volume BTCC processed on behalf of North Koreans, one former employee says the volumes were definitely not zero. As explored in a previous post, fake volumes among the Chinese exchanges was not uncommon and several of the large exchanges attempted to gain funding from venture capitalists while simultaneously faking the usage numbers. Isn’t China the root of all problems in Bitcoinland? It’s almost as if, in the current mania, no one cares about facts. As Hitchens might say: that which can be asserted without evidence, can be dismissed without evidence.
Is the Chinese government nationalizing Bitcoin? Is the Chinese government responsible for Bitcoin Cash. Bitcoin, what value would it bring to them? It would just be a cost center for them as miners don’t run for free. But what about Jihan and Bitmain? Aren’t they out to kill Bitcoin?
Bitmain benefits from repeat business and satisfied customers. Over the past two months there have probably been more than a dozen articles whitewashing proof-of-work mining energy consumption numbers. Coin Center, a lobbying group straight out of Thank You for Smoking, has its meme team out on continuous social media patrols trying to conduct damage control: no one must learn that Bitcoin mining isn’t free or that it actually consumes resources! The title of the article above is complete clickbait BS. Digital currency is wasteful by design. As the market price of a coin increases so too does the capital expended by miners chasing seigniorage.
This, we also both agree on. What Ou makes a mistake on is in her first sentence: digital currencies are not all wasteful, only the proof-of-work variety are. I know, I know, all other digital currencies that are not proof-of-work are crap coins and those who make them are pearl-clutching morons. Contra Ou and Coin Center, it is possible for central banks, and even commercial banks, to issue their own digital currency — and they could do so without using resource intensive proof-of-work. 1 million in capital to mine. If the network ever became cheaper to operate it would also mean it is cheaper to permanently fork the network.

You can’t have both a relatively high value proof-of-work coin and a simultaneously non-resource intensive network. While it is debatable as to whether or not Bitcoin mining is wasteful or not, it empirically does consume real resources beyond the costs of energy and the externalization of pollution onto the environment. 13 billion in capital over a year that miners will eventually consume in their rent-seeking race albeit from a combination of resources. 28 These are the eight largest proof-of-work-based cryptocurrencies as measured by real money market prices. Empirically we know that miners will deploy and consume capital up to the point where the marginal costs equals the marginal value of the coin. There are a variety of sites that attempt to gauge what the energy consumption is to support the network hashrate.

Perhaps the most frequently cited is Digiconomist. For the month of December, the network hashrate for Bitcoin hovered around 13. To get a lowerbound on how many hash-generating machines are being used, let’s look at a product called the S9 from Bitmain. So, if we were to magically wave our hands and replace all of the current crop of Bitcoin mining machines into the most efficient off-the-shelf product, we’d need about 1 million of these to be manufactured, shipped, installed, and maintained in order to generate the equivalent hashrate that the Bitcoin network has today. Multiply 1 million S9’s times the amount of energy individually used by a S9 and you’d get a realistic lowerbound energy usage for the network today. So what are the upperbound costs? The tweet above is not a rare occurrence.

If you are reading this, you probably know someone who tried to mine a cryptocurrency from an office computer or maybe their computer was the victim of ransomware. You may not think of much of the externalization and socialization of equipment degradation that is taking place, but because mining is a resource intensive process, the machines used for that purpose depreciate far faster than those with normal office usage. Even if miners eventually fully utilize renewable energy resources, most hash-generating machines currently deployed do not and will not next year. According to Bitnodes, Bitcoin has around 11,745 nodes online.
So is there an actual upperbound number? There is, by dividing hashpower by cost and comparing to costs of various known processor types. For instance, see this footnote for the math on how two trillion low-end laptop CPUs could be used. In theory, and practice, the upperbound is not infinite. Ethereum mining alone is driving up DRAM prices. But some Bitcoin and cryptocurrency enthusiasts are actively whitewashing the environmental impact of their anarchic systems and cannot empirically claim that their proof-of-work-based networks are any less wasteful or resource intensive than the traditional foreign capital markets they loathe.
In point of fact, while the traditional financial markets will continue to exist and grow without having to rely on cryptocurrencies for rationally pricing domestic economic activity, in 2018, as in years prior, Bitcoinland is still fully dependent on the stability of foreign economies providing liquidity and pricing data to the endogenous labor force of Bitcoin. On the face of it, MIT’s DCI effort makes a lot of sense: one of the world’s most recognized institutions collaborating with cryptocurrency developers and projects worldwide. But beneath the slick facade is a potential conflict of interest that has not been looked at by any media outlet. 1 million a year to be a partner. 39 What this allows the central bank to do is send staff to MIT and tap into its research capabilities.
