Bitcoin: this is what a bubble looks like

Not if, but when, the bubble will burst.

This is what a bubble looks like:

That's the market capitalisation of Bitcoin, an innovative fiat currency which relies on some fancy cryptography to create a perfectly decentralised and unhackable store of value. The graph shows the total value of all bitcoins in circulation — and it's currently peaking at a little over half a billion dollars.

In a sense, Bitcoins are the ultimate fiat currency. There is absolutely nothing valuable about them except the extent to which others are prepared to take them as payment for goods and services. The willingness relies on a certain level of trust that the currency will stay a useful store of value, measure of exchange and unit of account in the near future; but whereas normal currencies derive the trust from the fact that they are backed up by respectable governments and independent central banks, Bitcoin derives it from a complex, and essentially permanent, set of rules which issue new bit coins at a steadily declining rate until the early 22nd century, when the total quantity of bitcoins in circulation will be fixed forever.

Currently, bitcoin is very useful for fringe-legal transactions, and as a digital-native currency, it has potential to be used in a wide array of web services. But that's not why the value of the total economy has more than tripled since January. For that, look to lessons we learned over four hundred years ago.

The South Sea bubble is one of the most famous boom-and-bust cycles in history. At the peak of the madness, famously, a huckster appeared public advertising stock in "a company for carrying out an undertaking of great advantage, but nobody to know what it is". Naturally, he disappeared soon after.

But looking back at contemporary sources reveals something else which is just as important: very few people caught up in the madness thought that they were buying something innately valuable. These weren't naïve investors spending exorbitant sums on stock which they thought would vest unrealistic rewards; instead, they knew full well the bubble they were buying into, but thought that they could sell out of it at profit before the whole thing came crashing down. Some did; but inevitably, many others failed.

Much the same seems to be at play in the Bitcoin ecosystem. It's not just people like Hugo Rifkind, who accidentally made £41 from his foray into bit coin investing; Timothy Lee, a writer for Ars Technica, holds nearly a tenth of his investment portfolio in bitcoin, having bought in last January and seen a ten-fold increase in value.

But while there's been a massive increase in bitcoin price, there's not been anywhere near an equivalent increase in the currency's use. A glance at blockchain.info, which displays all transactions, shows that the vast majority of bitcoin transactions—by number, if not by value—are made at the site SatoshiDICE, a gambling organisation. In fact, the ever-increasing value of bitcoins is like to act as to depress the bitcoin economy, as people decide to hold on to their money rather than exchange it for services, knowing that it will surely increase in value.

The crash will come. At the heady peaks it's at right now, only the slightest spark will be required to turn the trend negative. In 2011, the previous bubble burst when Mt Gox, then the most popular bureau d'exchange for the fledgeling currency, was disastrously hacked. This time, I doubt it would take that. The peaks are so high, and so many people have so much money "invested" in the currency, that the rush to be the first out of a bear market will be vicious to behold.

How gendered are this year’s most popular Christmas present toys?

Meet the groups fighting back against the gendering of children’s toys over the festive season.

You’re a young girl. You go into WH Smith’s to pick out a colouring book for Christmas. You could buy the Girls’ World Doodling and Colouring Book, a "gorgeous gift for any girl". In this, the pictures range "from flowers, fans, feathers, to birds, buttons and butterflies". Or Colouring for Girls: Pretty Pictures to Colour and Complete, where you can colour in "beautiful birds, seashells, cupcakes, pretty patterns and lots more". The counterpart Boys’ Colouring Book has a range beyond buttons and feathers: "Planes, trains and automobiles – plus the odd alien spacecraft".

In the run-up to Christmas, this kind of gendered marketing is rife, particularly finding its way into the predominantly pink colour scheme of girls’ toys.

Take Amazon’s page "2016 Toys for Girls": a pink icecream trolly set, a pink light-up tablet, pink building blocks, pink and purple friendship bracelets and so on.

There are several groups taking action against the "pinkification" of children’s toys. One of these is Let Toys Be Toys, a group that targets large supermarkets with the aim of reducing the gendered marketing used on children’s goods.

The Let Toys Be Toys blog focuses on specific examples of targeted gendering within shops, catalgoues and online. A particularly revealing example of how prevalent this has become in recent years is in two pictures published from the Argos catalogue, one from the Seventies, and one from nowadays. The eye-wateringly pink page from now makes the 1970s page look dour by comparison. The lack of change over four decades of what kind of products are marketed at girls is equally striking:

Despite the efforts of campaign groups such as Let Toys Be Toys, the prevalence of gendering within the highest-rated children's gifts for 2016 is staggering.

Look no further than the Ultimate Christmas Gifts Guide from Toys R Us. One of the most immediately obvious examples is the way in which the pink/blue colour schemes are used to market identical products. This is repeated again and again:

This identical drawing board is uniquely packaged to the binary colour codes that are so common within children's toys stores.

The same applies with this keyboard, where the young girl and boy are pictured almost identically, save for the coordination of their clothes to the colour of their toys.

The message is a hugely limiting one: one that allows little movement away from the binary of pink/blue. The effects of this are longstanding. A recent poll from YouGov shows that "only a third of parents approve of boys playing with Barbies". The data goes on to explain that "while most parents approve of girls playing with toys marketed to boys, a minority of adults approve of the opposite".

Images like this were the inspiration behind Let Toys Be Toys, back in 2012. The campaign began on Mumsnet, the forum for parents, on a section called "AIBU", which stands for "Am I Being Unreasonable?". One parent posted the question: "Am I being unreasonable to think that the gendered way that children’s toys are marketed has got completely out of hand?" The heated discussion that followed led to a sub-section with the founding memebers of Let Toys Be Toys.

This aside, Let Toys Be Toys has made signifcant progess since it began. It targets large stores, focusing on gendered signage both in store and online. In their four years, they have campaigned for signs like "girls' toys" and "boys' toys" to be removed from retailers such as Boots, Debenhams, Morrisons, Toys R Us and TK Maxx. It is the go-to hashtag on Twitter for examples of the often shocking gendering of children’s toys.

"This is ostensibly about toys, but what we’re really talking about is gender stereotypes that shape our children’s worlds in an apparently very unassuming way," says Jess Day, a Let Toys Be Toys campaigner. "It seems very innocent, but actually what we’re doing is giving children very clear instructions about how to be a man and how to be a woman."

These clear instructions work beyond colour coordination: where girls are sold the image of the pink "girly girl", for instance. This is evident in children’s fancy dress costumes. Early Learning Centre’s (ELC) children’s fancy dress range imposes very rigid gender roles. To give examples from the current christmas range:

Again, the predominant colour sceme is pink. The roles offered are mainly fairies and princessess: generally make-believe.

“I found it really interesting that there were almost no ads showing girls doing anything," comments Day. "Physically they were very passive. The only physical activity we saw girls doing was dancing. They weren't really moving around much."

By contrast, young boys are offered the possibility of pretending to be a firefighter, a policeman or a doctor, among other practical, professional roles.

This year's Toys R Us Christmas advert follows on from this, with girls mainly dressed as princesses, and boys dressed as knights and kings. Much like the pink/blue colour scheme that we see all over children's shops, these fancy dress costumes create an unnatural binary. They send out a message that restricts any kind of subversion of these two supposedly polar opposites.

What's more, the subtext is one that is deeply rooted in expectations, building up a picture where careers such as that of a policeman and fireman come more naturally to boys, who have been socialised into these roles from childhood through fancy dress costumes of this type. Instead, girls are later forced to learn that most of us aren't going to become princessess, and none of us fairies – and so the slow process begins to unlearn these expectations.

There are certainly groups who try to counteract this. Manufacturers such as the toy brand IamElemental aims to break down the gendered distinctions between boys' toys and girls' toys, by creating female action figures.

“We always say that we are not anti-doll or anti-princess, but that if you give a girl a different toy, she will tell a different story," says Julie Kershaw, a member of the organisation. "As the mom of two boys, I always say that it’s just as important to put a strong healthy female action figure in a boy’s hand as it is a girl’s”.

Like the campaigners behind Let Toys Be Toys, IamElemental sees children’s toys as the starting point.

“We want kids – both girls and boys  – to internalise these messages early and often,” says Kershaw. “While there are certainly biological differences between girls and boys, gender-specific toys are not a biologically dictated truth. Toys are not “for girls” or “for boys”  – toys are for play; for exploration and creative expression.”

This attitude is ingrained in a child’s early years. Only through reconfiguring the gender sterotypes of the toys we buy for our children can we begin to break down their expectations of how to behave in age. We challenge you this Christmas to avoid these highly gendered products. Below are our three favourite Christmas presents for children this year, for girls AND boys, as approved by Let Toys Be Toys:
