When the speculators flee, what will be left of Bitcoin?

The underlying currency might not work without the inflated prices.

Last week's post pointing out bubbly appearance of Bitcoin's market capitalisation sparked some kickback. That was to be expected; in any bubble, people who are currently exposed to the possibility of a crash are unlikely to take the news well. Bitcoin has even more die-hard defenders than most bubbles, though, because of the mixture of political and cultural factors which cause a lot of people to invest such hope in it.

Amongst the currency's fanbase – and the fact that a currency has a fanbase is itself notable – are libertarians who decry any government involvement in the free market, techno-utopians who love the idea of fully digital money, monetary hawks who like the fact that the success of bitcoin would basically end inflation, and, frankly, criminals who like a completely untraceable currency (I'm not implying that if you like an untraceable currency you must be a criminal, but there's no denying that Bitcoin is a big deal for sites like Silk Road), as well as your common-or-garden speculators. All of them (except maybe the criminals) have a bigger reason to hope for the success of Bitcoin than just financial: if it succeeds, it proves them right.

But I fear that there are very few arguments which can be made to prove the Bitcoin boom that we're seeing right now – which has resulted in a 250 per cent increase in the total value of the Bitcoin economy in just three months – isn't a bubble. The problem is that there is not really anything to point to in that time period to explain the massive increase, except the massive increase itself. So it may be comforting for Bitcoin fans that there is a Bitcoin hedge fund in Malta, but given that that hedge fund exists because of the boom, not the other way round, it doesn't explain anything.

In fact, in the last few months, there have been a few news events which ought, by rights, to reduce the value of the currency. Chief among them is the fact that the block chain – the distributed record of every Bitcoin transaction, and the technical underpinning of the entire things – forked earlier this month, something it should not be able to do.

A transaction was made using a new version of the software, which was too large for earlier versions to handle. As a result, some clients accepted it, while others rejected it, leaving two valid block chains circulating. Some users are pointing to the fact that the currency is still circulating largely unaffected as a sign of its strength, but that's a bit like saying that the fact that your plane is still flying after its engine exploded makes the explosion good news.

The best way to justify the exponential increase in the market capitalisation of Bitcoin would be to point to a similar exponential increase in people using the currency to perform their everyday lives, and that simply hasn't happened. Take-up is strong, but nowhere near the level it would need to be to explain a half-billion market cap. Whereas speculation – people buying Bitcoin low to sell high – does.

(Note too I'm not saying that the currency is a Ponzi scheme, an accusation often levelled at it over the fact that the first holders of bitcoin had the most to gain from talking it up to others and then selling high. A bubble isn't necessarily the same as a Ponzi scheme, even a bubble which is deliberately engineered to reward its first buyers, and I don't think Bitcoin has those characteristics.)

The natural price of Bitcoin is far, far lower than where it stands right now, probably around the same level it was last summer, after its first catastrophic crash and before its second. The real question for the currency isn't whether it can survive being an investment for speculators – it can't – but whether it can survive as a currency when valued at 10 per cent of what it is currently.

The problem it faces is that the distributed computing which lets Bitcoin work is expensive. It takes energy, and time, and frequently also specialised hardware. The reward for doing so – "mining", in the parlance – is a randomly allocated share of the new coins produced through inflation. As time goes on, the currency will produce less and less extra coins this way, but for now, the bigger fear is if the natural price for Bitcoin can go low enough that it no longer becomes efficient to run these mining rigs.

There are still ways of getting around that – the technology allows for the payment of what is essentially a processing fee on top of each transaction – but it may be the case that Bitcoin's use as a currency is currently being subsidised by its bubble-tastic value. Hopefully the two are separate enough that even after the crash, Bitcoin can continue to function as an alternative way to send money over the internet. But the more Bitcoin fans boost the bubble, the bigger the shock's going to be when it pops.

Is defeat in Stoke the beginning of the end for Paul Nuttall?

The Ukip leader was his party's unity candidate. But after his defeat in Stoke, the old divisions are beginning to show again

In a speech to Ukip’s spring conference in Bolton on February 17, the party’s once and probably future leader Nigel Farage laid down the gauntlet for his successor, Paul Nuttall. Stoke’s by-election was “fundamental” to the future of the party – and Nuttall had to win.
 
One week on, Nuttall has failed that test miserably and thrown the fundamental questions hanging over Ukip’s future into harsh relief. 

For all his bullish talk of supplanting Labour in its industrial heartlands, the Ukip leader only managed to increase the party’s vote share by 2.2 percentage points on 2015. This paltry increase came despite Stoke’s 70 per cent Brexit majority, and a media narrative that was, until the revelations around Nuttall and Hillsborough, talking the party’s chances up.
 
So what now for Nuttall? There is, for the time being, little chance of him resigning – and, in truth, few inside Ukip expected him to win. Nuttall was relying on two well-rehearsed lines as get-out-of-jail free cards very early on in the campaign. 

The first was that the seat was a lowly 72 on Ukip’s target list. The second was that he had been leader of party whose image had been tarnished by infighting both figurative and literal for all of 12 weeks – the real work of his project had yet to begin. 

The chances of that project ever succeeding were modest at the very best. After yesterday’s defeat, it looks even more unlikely. Nuttall had originally stated his intention to run in the likely by-election in Leigh, Greater Manchester, when Andy Burnham wins the Greater Manchester metro mayoralty as is expected in May (Wigan, the borough of which Leigh is part, voted 64 per cent for Brexit).

If he goes ahead and stands – which he may well do – he will have to overturn a Labour majority of over 14,000. That, even before the unedifying row over the veracity of his Hillsborough recollections, was always going to be a big challenge. If he goes for it and loses, his leadership – predicated as it is on his supposed ability to win votes in the north - will be dead in the water. 

Nuttall is not entirely to blame, but he is a big part of Ukip’s problem. I visited Stoke the day before The Guardian published its initial report on Nuttall’s Hillsborough claims, and even then Nuttall’s campaign manager admitted that he was unlikely to convince the “hard core” of Conservative voters to back him. 

There are manifold reasons for this, but chief among them is that Nuttall, despite his newfound love of tweed, is no Nigel Farage. Not only does he lack his name recognition and box office appeal, but the sad truth is that the Tory voters Ukip need to attract are much less likely to vote for a party led by a Scouser whose platform consists of reassuring working-class voters their NHS and benefits are safe.
 
It is Farage and his allies – most notably the party’s main donor Arron Banks – who hold the most power over Nuttall’s future. Banks, who Nuttall publicly disowned as a non-member after he said he was “sick to death” of people “milking” the Hillsborough disaster, said on the eve of the Stoke poll that Ukip had to “remain radical” if it wanted to keep receiving his money. Farage himself has said the party’s campaign ought to have been “clearer” on immigration. 

Senior party figures are already briefing against Nuttall and his team in the Telegraph, whose proprietors are chummy with the beer-swilling Farage-Banks axis. They deride him for his efforts to turn Ukip into “NiceKip” or “Nukip” in order to appeal to more women voters, and for the heavy-handedness of his pitch to Labour voters (“There were times when I wondered whether I’ve got a purple rosette or a red one on”, one told the paper). 

It is Nuttall’s policy advisers - the anti-Farage awkward squad of Suzanne Evans, MEP Patrick O’Flynn (who famously branded Farage "snarling, thin-skinned and aggressive") and former leadership candidate Lisa Duffy – come in for the harshest criticism. Herein lies the leader's almost impossible task. Despite having pitched to members as a unity candidate, the two sides’ visions for Ukip are irreconcilable – one urges him to emulate Trump (who Nuttall says he would not have voted for), and the other urges a more moderate tack. 

Endorsing his leader on Question Time last night, Ukip’s sole MP Douglas Carswell blamed the legacy of the party’s Tea Party-inspired 2015 general election campaign, which saw Farage complain about foreigners with HIV using the NHS in ITV’s leaders debate, for the party’s poor performance in Stoke. Others, such as MEP Bill Etheridge, say precisely the opposite – that Nuttall must be more like Farage. 

Neither side has yet called for Nuttall’s head. He insists he is “not going anywhere”. With his febrile party no stranger to abortive coup and counter-coup, he is unlikely to be the one who has the final say.
