Did Bitcoin Just Burst? How It Compares to History’s Big Bubbles

Bitcoin’s recent wobbles have given fresh urgency to a question that’s gripped market observers for much of the past year: Will the cryptocurrency go down as one of history’s most infamous bubbles, alongside tulipmania and the dot-com craze?

The magnitude of Bitcoin’s boom (before it lost as much as 50 percent from its Dec. 18 high) suggests investors have reason to be worried.

As the chart shows, the cryptocurrency’s nearly 60-fold increase during the past three years was truly extraordinary.

It dwarfed the Nasdaq Composite Index’s gain during the headiest days of the 1990s. Going further back, it comfortably outstripped the Mississippi and South Sea bubbles of the 1700s. It even topped the Dutch tulipmania of the 1630s, though that last comparison should be taken with a grain of salt given the scarcity of recorded tulip values. (The chart includes prices for just one varietal; consistent post-peak figures were unavailable.)

Bulls say that Bitcoin’s boom is far from over, and that there’s more to analyzing a market than just measuring price gains. While the recent tumble has alarmed some investors, the cryptocurrency has bounced back from several previous swoons exceeding 50 percent. If Bitcoin did become a widely-accepted form of digital gold, as predicted by Cameron Winklevoss of Facebook fame, it could have a lot further to surge.

There’s also more than one way to slice a rally. On an annualized basis, Bitcoin’s three-year rise has been slower than the gains seen during several of history’s biggest manias — most notably the Mississippi and South Sea bubbles.

Still, skeptics abound. Howard Wang of New York-based Convoy Investments LLC and Jeremy Grantham of GMO LLC have analyzed Bitcoin’s advance relative to past frenzies and concluded that it’s unsustainable. Grantham, who helps oversee about $74 billion as GMO’s chief investment strategist, summed up his concerns in a Jan. 3 letter to investors:

“Having no clear fundamental value and largely unregulated markets, coupled with a storyline conducive to delusions of grandeur, makes this more than anything we can find in the history books the very essence of a bubble,” he wrote.

The strategist has a mixed record of success with such warnings. While Grantham was correct to call the 1990s surge in tech stocks a bubble, he exited too soon and missed out of some of the market’s biggest gains.

Only time will tell whether Grantham and other bears are right, wrong, or just too early when it comes to Bitcoin.

    Bitcoin falls $1,000 after South Korea promises crackdown on trading

    Move comes less than two weeks after high-profile digital currency exchange in Seoul was hacked and went bankrupt

    Bitcoin plunged by more than $1,000 (740) on Thursday after South Korea said it was planning a crackdown on trading in the digital currency in the latest of a string of warnings for investors.

    It dropped to about $13,500 after trading at about $15,400 on Wednesday. The dip was seen as a further illustration of bitcoins volatility.

    The cryptocurrency has surged in value this year by more than 900%, becoming one of the biggest stories in finance amid a slew of warnings of a pending market crash.

    Bitcoin recovered ground later on Thursday and was trading at about $14,000 at 5.30pm UK time.

    South Korea, which is one of the biggest markets in the world for bitcoin, said it was preparing a ban on opening anonymous cryptocurrency accounts and new legislation to enable regulators to close coin exchanges if they felt there was a need to do so.

    Q&A

    What is bitcoin and is it a bad investment?

    Bitcoin is the first, and the biggest, “cryptocurrency” a decentralised tradable digital asset. Whether it is a bad investment is the big question. Bitcoin can only be used as a medium of exchange and in practice has been far more important for the dark economy than it has for most legitimate uses. The lack of any central authority makes bitcoin remarkably resilient to censorship, corruption or regulation. That means it has attracted a range of backers, from libertarian monetarists who enjoy the idea of a currency with no inflation and no central bank, to drug dealers who like the fact that it is hard (but not impossible) to trace a bitcoin transaction back to a physical person.

    According to Reuters, the South Korean government issued a statement saying it had warned several times that virtual coins cannot play a role as actual currency and could result in high losses due to excessive volatility.

    The move came less than two weeks after the high-profile insolvency of one of the countrys digital currency exchanges, after the Seoul-based platform was hit by hackers for a second time.

    The exchange, called Youbit, shut down after losing 17% of its assets in a cyber-attack which was later blamed on North Korean hackers. The incident followed several other attacks against cryptocurrency platforms, such as a hack earlier in the month against the cryptomining marketplace NiceHash, which lost about 4,700 bitcoins in the attack.

    The crackdown in South Korea comes amid repeat warnings from leading figures in finance and some of the worlds top economists, who have said the currency is a vehicle for fraudsters and drug dealers. There are also fears that its rapid increase in value this year could quickly unwind, causing severe losses for investors.

    Sir Howard Davies, who chairs RBS, has likened investing in bitcoin to Dantes Inferno Abandon hope all ye who enter here while Jamie Dimon, the head of JP Morgan, has said bitcoin could potentially be worse than the tulip mania of the 17th century, when bulb prices rose vertiginously before crashing.

    However, several leading academics have said bitcoin poses no threat to the stability of the financial system, as its total value stands at about $240bn, paling in comparison with the total value of global shares at almost $80tn.

    Companies are also exploring ways to exploit blockchain which is the technology underpinning bitcoin and works by securely encrypting information to speed up everything in business from making payments to transferring data and contracts.

    Bitcoin rose to nearly $20,000 a week before Christmas, following the introduction of derivatives trading for major investment firms on the Chicago Mercantile Exchange, which enabled hedge funds to place bets on future prices. However, it then lost 25% of its value on 22 December, before recovering earlier this week and then slumping again on Thursday.

    While some have said more investors in the market could help support higher valuations, the currency is on a jittery run.

    Craig Erlam, senior market analyst at trading firm Oanda, said the recent fall in value could have made speculators more wary of the potentially negative news from Korea for its market price.

    We saw plenty of this in reverse on the way up, with positive news triggering significant rises and negative news being brushed aside. It wouldnt surprise me if we see prices heading back below $10,000 before they find their feet again, he said.

    Digital currencies have grabbed the attention of global regulators this year as a consequence of bitcoins rapid price growth, gaining in value from about $1,000 at the beginning of 2017. Other cryptocurrencies such as Ethereum, Ripple and Litecoin have also gained in value this year.

    Closer control of digital currencies by financial watchdogs could result in further volatility for bitcoin, as part of its attraction among supporters has been the lack of government and central bank oversight.

    The UKs Financial Conduct Authority has issued a warning about investing in initial coin offerings, which use digital tokens to raise funds for startup businesses and projects.

    The Criminal Underworld Is Dropping Bitcoin for Another Currency

    Bitcoin is losing its luster with some of its earliest and most avid fans — criminals — giving rise to a new breed of virtual currency.

    Privacy coins such as monero, designed to avoid tracking, have climbed faster over the past two months as law enforcers adopt software tools to monitor people using bitcoin. A slew of analytic firms such as Chainalysis are getting better at flagging digital hoards linked to crime or money laundering, alerting exchanges and preventing conversion into traditional cash.

    The European Union’s law-enforcement agency, Europol, raised alarms three months ago, writing in a report that “other cryptocurrencies such as monero, ethereum and Zcash are gaining popularity within the digital underground.” Online extortionists, who use ransomware to lock victims’ computers until they fork over a payment, have begun demanding those currencies instead. On Dec. 18 hackers attacked up to 190,000 WordPress sites per hour to get them to produce monero, according to security company Wordfence.

    For ransomware attacks, monero is now “one of the favorites, if not the favorite,” Matt Suiche, founder of Dubai-based security firm Comae Technologies, said in a phone interview.

    Monero's Rally

    Note: Figures shows percentage change in price compared with Oct. 31

    Monero quadrupled in value to $349 in the final two months of 2017, according to coinmarketcap.com, placing it among a number of upstart coins that rose faster than bitcoin, the world’s most valuable digital currency. Bitcoin roughly doubled in the same period, data compiled by Bloomberg show. Monero’s price has climbed another 7 percent so far this year, according to coinmarketcap.com.

    In monero’s case, criminals are snapping it up because bitcoin’s underlying technology can work against them. Called blockchain, the digital ledger meticulously records which addresses send and receive transactions, including the exact time and amount — great data to use as evidence. Match an address to a crime and then watch the bitcoin universe carefully, and you can see the funds disappear and reappear in other locations.

    Sleuths have developed databases and techniques for digesting that information to eventually nab wrongdoers. Say, for example, a coffee shop in Berkeley is known to have a certain bitcoin address, and a wallet used by an extortionist transfers the same amount there every morning at 9 a.m. Police can stop by and make an arrest.

    Started in 2014, monero is very different. It encrypts the recipient’s address on its blockchain and generates fake addresses to obscure the real sender. It also obscures the amount of the transaction.

    The techniques are so potent that software that flags coins suspected of being obtained through crime now tags just about anything converted into or out of monero as high risk, according to Pawel Kuskowski, chief executive officer of Coinfirm, which helps exchanges and other companies avoid tainted money. That compares with only about 10 percent of bitcoin, he said.

    “What we treat ‘high risk’ is something that’s anonymizing funds,” he said in a phone interview. “How are you going to prove that these funds are not coming from illegal sources?”

    Read a QuickTake: All about bitcoin, blockchain and their crypto world

    Monero is one of many privacy-focused coins, each offering different security features. Its main competitor, Zcash — which isn’t known to have a significant criminal following — can offer even better privacy protection. Instead of creating fake addresses to hide senders, it encrypts their true address. That makes it impossible to identify senders by looking for correlations in addresses used in multiple transactions to pinpoint the real one — a vulnerability for monero. Developers of the coin have made progress in reducing it, though.

    Still, Princeton University researchers recently developed a tool that helps them analyze Zcash transactions at least to some extent — but they haven’t been able to crack monero. And Zcash high-security features can’t be used on disposable burner phones, a favorite of criminals eager to stay anonymous.

    Developers behind monero say they simply created a coin that protects privacy. Most people use it legitimately — they just don’t want others to know whether they’re buying a coffee or a car, Riccardo Spagni, core developer at monero, said in a phone interview.

    “As a community, we certainly don’t advocate for monero’s use by criminals,” Spagni said. “At the same time if you have a decentralized currency, it’s not like you can prevent someone from using it. I imagine that monero provides massive advantages for criminals over bitcoin, so they would use monero.”

    ‘Utility’ Too

    Yet criminals are probably only a fraction of monero’s users, according to Lucas Nuzzi, a senior analyst at Digital Asset Research, which provides research to institutional investors.

    “As with any disruptive technology, many of the initial use cases revolve around illicit activities,” he wrote in an email. But as everyday people grow concerned about privacy and surveillance, “there is utility in these currencies that go beyond just a means of exchange for illicit goods.”

      Bitcoin loses a quarter of its value in one day’s trading

      Cryptocurrencys year-end rally fails as its investors are finally introduced to the law of financial gravity

      Bitcoin lost more than a quarter of its value on Friday as an analyst warned that investors in the cryptocurrency had finally been introduced to the law of financial gravity.

      In the latest illustration of bitcoins volatility, it slumped to below $11,500 at one point on Friday touching $11,159 having started the week at a record high close to $20,000 and in its biggest weekly fall since 2013. However, by 5pm London time it was trading at $12,800 as the currency endured a see-saw day.

      It is a sudden reversal of bitcoins upward trajectory this year, having started 2017 at $966, and sparked warnings that investors need to beware that they are not risking a rerun of the 17th century tulip bubble.

      Bitcoin trades on a number of exchanges and one, Coinbase, was reported to have suspended transactions temporarily while there was also a temporary halt of the new futures contract which allows investors to take bets on the value of the digital currency at a predetermined point in the future on the Chicago Board Options Exchange while it waited for the price to stabilised.

      Two futures contracts have been launched this month, which were regarded as taking a step towards legitimising digital currencies at a time when regulators are stepping up their surveillance of products linked to the new technology.

      Fridays slump was said to have been fuelled by the founder of another cryptocurrency selling his holdings. Charlie Lee, founder of Litecoin, said he was selling his holdings to avoid a conflict of interest that he faces when talking about the price of the currency which could appear to benefit him.

      Jasper Lawler, head of research at London Capital Group, said this decision was probably the root-cause of the insecurity thats been felt across the cryptocurrency space.

      Bitcoin investors were introduced to the law of gravity over the last 24 hours Long term holders will be used to this level of volatility but newer crypto traders could be permanently put off, said Lawler.

      The exponential price rise seen recently needs new investors to sustain it. In a bubble market its known as the bigger fool theory; you can buy high as long as there is a fool willing to buy it off you even higher, he added.

      Charles Hayter, founder and chief executive of industry website CryptoCompare, said: A manic upward swing led by the herd will be followed by a downturn as the emotional sentiment changes. A lot of traders have been waiting for this large correction.

      Sir Howard Davies, chairman of RBS, has likened investing in bitcoin to Dantes Inferno Abandon hope all ye who enter here while Jamie Dimon, the head of JP Morgan, has talked about bitcoin as being worse than tulip mania, which took place in the Netherlands in the 1630s, when bulb prices reportedly rose more than 1,000% in a month.

      Analysts said the dramatic moves in the runup to the end of 2017 meant that it was difficult to predict what would happen in the new year when trading volumes are expected to rise.

      Lukman Otunuga, research analyst at financial firm FXTM, said: The aggressively bearish price action witnessed this week may prompt investors to start questioning if bitcoin will recover from the selloff or remain depressed moving into the new year.

      Regulators have been sounding a cautious note about bitcoin, which is not regulated and is controlled by a network of computers that update all transactions which take place on a variety of trading platforms around the world. It only exists digitally and is mined using mathematical equations.

      While the Bank of England has said it is not a risk to financial stability, governor Mark Carney told MPs this week that he expected international regulators will discuss cryptocurrencies and the potential future role of central bank digital currencies.

      The Financial Conduct Authority has issued warnings about initial coin offerings (ICOs) which use cryptocurrencies to raise funds for startup businesses. Investors in ICOs pay in cryptocurrencies such as bitcoin and receive a coin in return, rather than shares in the company.

      Andrew Bailey, chief executive of the FCA, has said bitcoin is not a really currency but more like a commodity.

      Bitcoin price crashes, loses $2,000 in a few hours

      It's about time you learned how Bitcoin works.
      Image: pixabay

      Bitcoin’s bubble just burst, at least a little bit.

      The high-flying cryptocurrency declined more than $2,000 dollars in the span of a few hours on Wednesday. It’s one of the sharpest drops in recent memory and a stark reminder of the volatility of the cryptopcurrency that is suddenly on everyone’s mind.

      Bitcoin’s recent rise happened almost as quickly as its Wednesday decline. Bitcoin enthusiasts cheered on Tuesday as 1 BTC surpassed $10,000 for the first time, only to see it hit $11,000 the next day

      Wednesday’s crash pushed Bitcoin’s value below briefly below $9,000 on at least one exchange, though it appeared to have recovered some value shortly thereafter. As of 3:17 P.M. EST, Coindesk had Bitcoin trading at $9,852.54.

      It continued to recover throughout the day, trading around $10,100 around 5 P.M.

      The graph below, from Coindesk.com, shows the sudden drop off on Wednesday afternoon.

      Even with the decline, one Bitcoin is worth more than it was a week ago, when it was trading around $8,000, and far more than one year ago, as the graphs below show.

      Image: coindesk.com

      Thought Bitcoin is still far more valuable now that it was even just a little while ago, Wednesday’s sudden decline shows just how volatile Bitcoin can be, even as it gains wider acceptance as a viable store of value. 

      The decline also provides more fuel for Bitcoin skeptics who have been sounding the alarm over what they see as dangerous speculation. It also triggered plenty of schadenfreude on Twitter.

      Bitcoin is a vehicle for fraudsters, warns Goldman Sachs boss

      CEO Lloyd Blankfein attacks cryptocurrency after worth dives 20% in a day, stating bank will not get included till it ends up being less unpredictable

      The employer of Goldman Sachs ended up being the current prominent critic of bitcoin, declaring it was a lorry to dedicate scams as the worth of the cryptocurrency plunged 20% in less than 24 hours.

      Lloyd Blankfein , president of the United States financial investment bank, stated: “Something that moves 20% [over night] does not feel like a currency. It is a lorry to commit scams.”

      Bitcoin is the very first, and the most significant,”cryptocurrency “– a decentralised tradable digital possession. Whether it’s a bad financial investment is the$ 97bn concern(actually, because that’s the existing worth of all bitcoins out there). Bitcoin can just be utilized as a circulating medium and in practice has actually been much more crucial for the dark economy than it has for a lot of genuine usages. The absence of any main authority makes bitcoin extremely resistant to censorship, corruption– or policy. That suggests it has actually brought in a variety of backers, from libertarian monetarists who take pleasure in the concept of a currency without any inflation and no reserve bank, to drug dealerships who like that it’s tough(however possible)to trace a bitcoin deal back to a physical individual.

      Thank you for your feedback.

      His remarks came throughout another hugely unpredictable trading session for the digital currency, which plunged by over $2,000 in a 24-hour duration. Having actually topped $11,000 to reach a brand-new record high of $11,395 on Wednesday, it was up to a low of $9,000 on Thursday, prior to getting a little later on in the day.

      Blankfein stated Goldman did not have to have a bitcoin technique, including the digital currency would have to be a lot less unpredictable and a lot more liquid to validate closer attention.

      “When do I need to have a bitcoin technique? Not today. Life needs to be truly rosy if that is exactly what we are discussing,” he stated. “Bitcoin is not for me. A great deal of things that have actually not been for me in the previous 20 years have actually exercised, however I am not thinking that this will exercise.”

      Blankfein is the current manager of a significant bank to voice scepticism about bitcoin, after JP Morgan’s president, Jamie Dimon, explained it as scams that would eventually explode and stated it was just suitable for usage by drug killers, individuals and dealerships residing in locations such as North Korea.

      On Wednesday, Sir Jon Cunliffe, a deputy guv of the Bank of England, stated the digital currency was too little to position a systemic risk to the international economy. He likewise warned that bitcoin financiers required “to do their research”.

      Despite the fall in bitcoin’s worth on Thursday, it stayed far greater than it was at the start of 2017, when it was trading at $998. It is the greatest gainer of all possession classes this year, triggering sceptics to state it a timeless speculative bubble that might break.

      Banks and other banks stay worried about bitcoin’s early associations with cash laundering and online criminal offense. Unlike conventional currencies, bitcoin is not released or managed by a reserve bank or federal government.

      Lee Wild, head of equity method at online trading business Interactive Investor, stated the volatility in bitcoin trading was “wild west things”.

      “Cryptocurrency land’s severe volatility resembles catnip to high-risk traders, as well as standard financiers are dipping their toe. Provided there’s no rational method to value them with any precision, this stays wild west things.”

      Analysts at the spread wagering company, City Index, stated: “While standard properties are experiencing traditionally low levels of volatility, the whipsaw action of the bitcoin is drawing the attention of standard traders.

      Bitcoin Crashes and Then Surges in Wild Weekend Action

      Bitcoin is showing that buying digital currencies isn &#x 2019; t for the faint of heart.

      After plunging as much as 29 percent from a record high following the cancellation of an innovation upgrade on Nov. 8, the biggest cryptocurrency came roaring back in early trading Monday prior to varying in between losses and gains.

      &#x 201C; Crypto trading is not for the newbie financier, &#x 201D; stated John&#xA 0; Spallanzani, primary macro strategist at GFI Securities LLC in New York.

      While several factors are being pointed out for the cost volatility, among the more feasible is that some financiers are changing to alternative coins. Bitcoin money, a spin-off of bitcoin that consists of much of the technical upgrades being discussed by designers, has actually more than doubled in the very same duration.

      &#x 201C; We have actually seen comparable high falls in bitcoin throughout the year– particularly in June and September– however each time a substantial decrease happens, brand-new financiers leap in to experience the brand-new property class, &#x 201D; Hussein Sayed, primary market strategist at ForexTime Ltd., a currency broker that utilizes the brand name FXTM, composed in a note Monday.

      While markets had actually been concentrating on bitcoin &#x 2019; s more than 500 percent rise this year, bitcoin money was acquiring appeal due to the fact that of its bigger block size. That &#x 2019; s a particular that makes deals less expensive and faster than the initial.

      When a faction of the cryptocurrency neighborhood canceled strategies to increase bitcoin &#x 2019; s obstruct size on Wednesday– a relocation that would have produced another spin-off– some fans of larger blocks rallied around bitcoin money.

      The resulting volatility has actually been severe even by bitcoin &#x 2019; s wild requirements and comes amidst growing interest in cryptocurrencies amongst regulators , banks and fund supervisors. While doubters have actually called its fast advance a bubble, the possession has actually ended up being too huge for numerous on Wall Street to overlook. After diminishing as much as $38 billion given that Nov. 8, bitcoin boasts a market price of about $110 billion.

      Supporters of bitcoin &#x 2019; s innovation upgrade &#x 201C; are now changing assistance to bitcoin money, &#x 201D; stated Mike Kayamori, head of Tokyo-based Quoine, the world &#x 2019; s 2nd most-active bitcoin exchange over the previous day. &#x 201C; There &#x 2019; s a panic about exactly what &#x 2019; s taking place.

On the other side is bitcoin money, which permits&#xA 0; its blockchain to manage 8 times as much information as the initial.

      Proponents of bitcoin money think their technique is easier and closer to the initial objective of bitcoin,&#xA 0; which &#xA 0; was explained mainly as a payment system in its white paper . Advocates of the initial bitcoin state that vision is too restricted,&#xA 0; which by enhancing the blockchain with SegWit innovation, bitcoin can end up being a brand-new digital-asset class that not just supports payments however numerous other functions.

      Upgrade Called Off

      While bitcoin money has actually been around for months, it saw restricted assistance as the neighborhood waited for recently &#x 2019; s innovation upgrade for the initial bitcoin, which assured comparable functions. Now that the upgrade has actually been aborted, services that utilize the cryptocurrency mainly as a payment approach are anticipated to increase adoption of bitcoin money.

      While bitcoin money rose over the weekend, it hasn &#x 2019; t been a straight line up. The cryptocurrency was trading at $1,300 at 4:45 p.m. in New York, below a high of about $2,478 on Sunday, Coinmarketcap.com costs reveal.

      Bitcoin has actually been likewise unpredictable; it at first increased after news that it would prevent another split, however the gains were short-term . Its plunge previously Monday to as low as $5,605 compares to an intraday record $7,882 on Nov. 8.

      Volume throughout bitcoin exchanges leapt to 436,021 bitcoins on Sunday, the greatest given that September, Bitcoinity.org information reveal. BitMEX, an exchange for cryptocurrency derivatives that permits shorting , saw record activity on Sunday, Chief Executive Officer Arthur Hayes stated.

        Everything you wanted to know about bitcoin but were afraid to ask

        The value of cryptocurrencies is rising fast. But is it sustainable? And how does it work, anyway? These questions, and many more, answered

        The money has become too much to ignore and so bitcoin and cryptocurrencies are back in the news. You may have heard about Ethereum, a cryptocurrency that has risen in value by more than 2,500% over the course of 2017. Or maybe youve heard about one ofthe many smaller cryptocurrenciesthat raised hundreds of millions of dollars in the first few days they were on sale, during their initial coin offering. Or youve just spotted that bitcoin, which made headlines in 2013 for hitting a high of $200, is now worth nearly $7,000 (5,250), making a lot of people very rich in the process.

        Are these cryptocurrencies simply speculative bubbles or will they actually transform our financial system? Its time to answer afew common questions about this new technology and assess whether a lot of people have just pulled off the investment of their lifetime or made a hugemistake.

        What actually is bitcoin?

        Bitcoin is a cryptocurrency, the first and still the biggest example of its type. At its core, its a new form of digital asset, created through a cannycombination of encryption (the same technology that protects WhatsApp from eavesdropping) and peer-to-peernetworking (which allowed music piracy to blossom in the 00s through services such asKazaa).

        If you own a bitcoin, what you actually control is a secret digital key you can use to prove to anyone on the network that a certain amount of bitcoin is yours.

        If you spend that bitcoin, you tell the entire network that you have transferred ownership of it and use the same key to prove that you are really you. In that respect, your key is similar to a password that allows you access to your money, except with no possibility of resetting your key if you lose it. Anyone else who manages to discover your key would gain total, irreversible control over your cash. The history of all the transactions made is a lasting record of who ownswhich bitcoin: that record is called theblockchain.

        What are its advantages over money created by central banks?

        Bitcoin advocates will point to a number of possible advantages, from the ability to use the blockchain to track things other than simple money to the built-in support for smart contracts, which execute automatically when certain conditions are met.

        But the biggest advantage, and the only one everybody agrees on, is that bitcoin is decentralised and so extremely resistant to censorship.

        Although its possible to observe a bitcoin payment in process, its not practicably possible to stop it. That makes it radically different from conventional banking, where banks can, and do, intervene to freeze accounts, vet payments for money laundering or enforce regulations. That has made it a haven for activities from cybercrime and drug trading to enabling international payments to closed economies and supporting radically off-grid living.

        So will I need to start taking bitcoin to Tesco for my weekly shop?

        Unlikely. Bitcoin has one major hurdle to being used at scale for physical transactions: payments are only confirmed once every 10 minutes (and thats when everythings working well; in practice, it can take days for confirmation to occur). This means theoretically that its possible to spend a bitcoin, then walk next door and spend exactly the same bitcoin at a second establishment. Only one of those transactions will ultimately be confirmed, leaving the other place out of pocket.

        More generally, bitcoin has limited advantages for payments between big companies and normal consumers. Its no easier or quicker than any other mobile payment, it introduces considerable volatility to your daily holdings (or a sizable hedging cost to guard against swings in the value of the currency) and remains a pain to integrate with the conventional banking system.

        That hasnt stopped some large companies experimenting. Microsoft accepts bitcoin for payments on its online store and PayPal offers integration for merchants to offer the cryptocurrency as a payment option.

        Is it really the new gold?

        Probably not, but the comparison isnt completely spurious. One of the interesting quirks of bitcoin is that there will never be more than 21m of them in existence. That figure is written into the currency at its source code and is a function of how the network rewards those people who provide the computing power (called miners because of that gold analogy) that keeps it ticking over.

        Every 10 minutes, one of the miners is rewarded with a sum of bitcoin. That reward doesnt come from anyone: it is created out of thin air and added to the bitcoin wallet of the miner. Initially, that reward was 50 bitcoin, but it gets halved every four years, until, midway through the 22nd century, the last bitcoin ever will beproduced.

        For a certain type of economist, that hard limit is an extremely good thing. If you believe that the key problem with the financial system over the past 100 years has been that central banks print money, creating inflation in the process, then bitcoin provides an alternative ecosystem where inflation is capped forever.

        Does it really create more carbon dioxide than Ecuador?

        Yup. And then some. Citibank estimates that the bitcoin network will eventually consume roughly the same amount of electricity as Japan. The problem is that the mining process is incredibly wasteful and deliberately so. Those miners are all competing to be the first to solve an arbitrarily difficult computing problem, one that takes enormous amounts of processor cycles to do and still comes down mostly to luck. The computer that does solve it first, every 10 minutes, gets a sizable reward currently in the region of 65,000 in bitcoin but every computer, not just the winner, has had to spend that processing time to do the maths.

        The reason for the mining requirement, which is essentially asking a computer to continue rolling a dice until it rolls a few thousand sixes in a row, is that it ensures that no single person can dictate what happens on the network. The proof that the miner has solved the problem is what it uses to claim its reward, but it also becomes the seal that it uses to verify the last 10 minutes of transactions.

        I, miner number 2357398, have solved this problem, and the answer is [extremely long string of digits]. By the authority vested in me by the network, I declare that the following list of transactions to be confirmed: and then they list every transaction that they have heard about in the last ten minutes.

        From that point on, every machine on the network begins solving a new problem, set by the last miner. But, crucially, they only do so if they agree with the miners list of transactions. That means that even if you do win the race, its not enough to simply insert your own lies in the block, and declare that everyone sent you all their money, because everyone else will simply ignore you and listen to the next miner in the chain.

        (The reward itself isnt really necessary to Bitcoin, but its there to ensure that miners have some reason to throw their electricity at the network. In the long-run, the hope is that voluntary transaction fees for quicker confirmations will take over that role.)Because the problem is so processor-intensive and so randomly rewarded, its prohibitively expensive in electricity and computing power to attempt to fake it. But its also a vast use of electricity, worldwide, used to do little other than satisfy an arbitrary requirement for spending money.

        Is bitcoin the only cryptocurrency?

        Not at all, although its still the most valuable. After bitcoins creation in 2009, a number of other cryptocurrencies sought to replicate its success by taking its free, public code and tweaking it for different purposes.

        Some had a very defined goal. Filecoin aims to produce a sort of decentralised Dropbox; as well as simply telling the network that you have some Filecoins, you can tell it to store some encrypted data and pay Filecoins to whoever stores it on their computer.Why would you want that? Well, it again comes back to censorship resistance. If you store something on your Dropbox that the company doesnt like, it can just delete the data and ban you. With Filecoin, its impossible to tell whats being stored, and impossible to force the network to block any given user anyway.

        Others are more nebulous. Ethereum, now the second biggest name after bitcoin, is essentially a cryptocurrency for making cryptocurrencies. Users can write smart contracts, effectively programs that can be run on the computer of any user of the network if theyre paid enough Ether tokens.Think, for instance, of offering a small sum every time someone responds to a particular signal with todays headlines: youve built a decentralised news website, then. Or you could write a small program and reward someone every time its run: that way, youve created a decentralised cloud computer.

        As a category, these new cryptocurrencies are increasingly referred to as decentralised apps, or dapps, with the focus being not on the specific currency used to make the system work, but on its overall goal.It might even be best not to think of the coins that lie at their heart as currency at all: when the token could represent a services contract, a land registry record, or the right to five minutes of computing time, the analogy to pounds and dollars has rather broken down.

        What is driving the price rise?

        Thats the billion-dollar question. A few different explanations have beenoffered.

        Some fans will say that the price rise is simply a correction to the natural rate of growth for bitcoin. Sure, they argue, the technology has had its booms and its busts, but if it is to become a worldwide digital currency, its value will definitely be higher than it is today. In that narrative, the price rise is simply a reflection of the growing acceptance of bitcoin.

        Other fans point to the growth in novel cryptocurrencies. Because of bitcoins maturity, and its focus on finance, if you want to buy some Ether, some Filecoins or any other cryptocurrency, its usually easiest to buy bitcoin with your conventional currency and then trade bitcoin for the cryptocurrency of your choice. Naturally, then, booms in those currencies are leading to booms in bitcoin itself, as more and more people attempt to buy into the whole system.

        Then theres the bubble argument. There, people argue that the majority of the price rise is due simply to people buying bitcoin in the hope that they can sell it later for a profit. A classic speculative bubble, some people will make a lot of money while others will lose everything.

        So is it a bubble?

        Few would argue that there isnt a lotof speculation in the cryptocurrency market. There are adverts on the London underground, and all over Instagram and Facebook, encouraging viewers to invest in cryptocurrencies and, judging by the amount of money flowing in to the ecosystem, a lot of people are taking up the offer.

        At some point, those people will get flighty and try to cash out their gains. If enough do at once, the price of bitcoin will take such a tumble that it will prompt a run and well see the classic crash.

        But the real question is not whether this will happen, but when and how big the crash is. Three times now, bitcoin has had boom-and-bust cycles that have seen vast amounts of value destroyed, but have still left the currency valued higher than it was before the previous boom began. (Personally, I first called bitcoin a bubble in print when one coin was worth $30. After the crash that followed, one coin was worth $120.) Its not a smooth ride up, but that doesnt mean its a total bubble.

        What is a hard fork?

        As the bitcoin network has grown, its hit problems. For dull, technical reasons, the network as it was initially designed struggles to deal with the amount of traffic that flows through it these days, leaving huge delays in the amount of time it takes for a transaction to be confirmed.

        In a normal, centralised, business, that wouldnt be a problem: simply update the software and move on. But a bitcoin update requires convincing every single miner to accept the new software otherwise, the miners who carry on running the old version are effectively running a completely different currency from those who have updated.

        This is known as a hard fork, and for the first six years of bitcoins life, it was the nightmare every developer tried to avoid. But recently, divisions among the community have become so fractious that multiple hard forks have occurred, all around how to deal with this traffic slowdown.

        With names like Bitcoin Classic, Bitcoin Unlimited, and Bitcoin Gold, each claims that it is the true heir to the original vision but with each fork, the playing field becomes more crowded.

        Nothing is destroyed with each fork: if you had 100 bitcoin before Bitcoin Cash split off, after the split you still had 100 bitcoin and you had 100 Bitcoin Cash. But with each fork, the playing field becomes more crowded, more confusing for newcomers, and the overall reputation for (relative) stability becomes more eroded. Another fork, SegWit2x, was due to happen in late November, but its backers decided at the last minute it didnt have enough support and called it off.

        Whats the banking establishments viewof bitcoin?

        It varies greatly. Some, such as JP Morgan Chase head, Jamie Dimon, are extremely dismissive of the wholething, arguing that the very properties of bitcoin that make it so appealing as a form of digital gold are why its doomed to remain a niche prospect. For Dimon and co, the volatility of its exchange rate, lack of any economic oversight to control monetary policy and absence of support from major nation states mean bitcoin cant ever truly replacepounds and dollars and is therefore a failure.

        Few disagree with that conclusion, but some bankers point to other advantages of the technology. The blockchain concept, they say, might be useful in conventional banking too. Forget bitcoin itself and focus instead on the value of a distributed ledger. What if all the major banks replaced their normal book-keeping with one shared, but still closed, database? Might that help cut down on fraud and ensure a more level playing field?

        And then, of course, there are the advantages of bitcoin that conventional banking cant hope to compete with – and doesnt want to. Can a shadow currency exist purely on the back of drug dealing and cybercrime? Quite possibly: both are big businesses, and neither shows any sign of going away.

        Whats the latest on the identity of Satoshi Nakamoto?

        Hes still a mystery. The pseudonymous founder of bitcoin, Nakamoto appeared out of nowhere in 2008 when he published the white paper that described how his proposed digital currency would work. While he was active in the online community around bitcoin for the first couple of years of the currencys life, he posted less and less, making his last ever post on 12 December 2010.

        Since then, a lot of people have been accused by others of being the real identity behind Nakamoto. Some of those accusations have been farcical Newsweek fingered a Japanese-American man named Dorian Satoshi Nakamoto as the inventor, leading to a slow-motion car chase around LA before the man had a sushi dinner with one hand-picked reporter, during which he repeatedly referred to bitcom and begged to be left alone.

        Others have been based on the background discussion around cryptocurrencies at the time: leading thinkers such as Hal Finney and NickSzabo were named, on the basis of similar areas of research. Both mendenied being Nakamoto and pointed out that they were active under their own names at the time bitcoin was launched, with Finney (who died in2014) being the currencys secondever user.

        Only one person has credibly claimed to be Nakamoto himself: Australian computer scientist Craig Wright. In 2016, Wright went public and gave a number of long interviews to the BBC, GQ, the Economist and London Review of Books, in which he claimed that he would provide evidence proving he is Nakamoto. When the evidence was released, however, it was flawed, proving nothing and leading some to accuse him of scammery.

        Since then, there have been no other major names linked to Nakamotos identity and no action on the bitcoin holdings linked to his account, currently worth around $7bn. It is possible the world may never know who invented bitcoin. For many in the field, thats how it should be.
