Monnaies virtuelles, mondes réels. Un des effets les plus inattendus et les plus intéressants de la crise chypriote aura été de mettre en lumière le rôle que commencent à jouer, et que joueront de plus en plus, les monnaies virtuelles, dans la formidable évolution de la finance moderne, pour le meilleur et pour le pire.

Monnaies virtuelles, mondes réels

Créées depuis plus d’une vingtaine d’années, leur premier rôle était de permettre d’attribuer des biens spécifiques, rendus disponibles par des programmes de fidélités ( des miles) ; puis, de permettre à un joueur de jeu vidéo d’acheter des armes pour un jeu de combat ou des accessoires pour un jeu de construction . Ces monnaies virtuelles peuvent être obtenues en récompense de progrès dans le jeu ou en en acquérant auprès d’un vendeur, contre de la monnaie réelle. Ce qui se joue cette semaine avec l’une d’entre elle, le bitcoin, est particulièrement intéressante. Ces monnaies ouvrent cependant à deux dérives dangereuses, qu’on connait déjà pour le reste du système financier: Silk Road: the online drug marketplace that officials seem powerless to stop.

Among the usual bills is a small padded envelope. Though it doesn't have his name on, it's the package he's most interested in: inside lie two grams of, he hopes, relatively pure MDMA. Johnson has no idea who has sent him the envelope: he has never met his dealer, and never will. Bitcoin is in hyperdeflation.

He writes: So a few weeks ago, a pizza might have cost you one Bitcoin. Today it might only cost you a fifth of a Bitcoin, which sounds great, but then if you're looking at the above chart, why would you spend anything? Why would you buy a pizza (or pot or anything else) when tomorrow your Bitcoin will be worth more? With this kind of chart, you'd be insane to do anything but hoard your coins.So yes, all the hype is great for some folks in the ecosystem, but ultimately there's a reason that over time, government prefer to see their currency slowly depreciate.

On The Money-ness Of Bitcoins

Against the background of renewed concerns about the integrity of the euro zone and the imposition of capital controls in Cyprus, the price of a bitcoin has tripled over the last month and reached more than $141 for 1 BTC. Are we witnessing the spontaneous emergence of an alternative virtual medium of exchange, as some would put it? This article offers an answer to this question by considering three aspects of the economy of bitcoins: their production process, their demand factors, and their capacity to compete with physical media of exchange. The Production of Bitcoins. Le Bitcoin, la monnaie virtuelle qui surfe sur la crise. Bitcoin 2012 London: Richard Stallman. Cryptocurrency.

When the virtual currency bitcoin was released, in January 2009, it appeared to be an interesting way for people to trade among themselves in a secure, low-cost, and private fashion.


The Bitcoin network, designed by an unknown programmer with the handle “Satoshi ­Nakamoto,” used a decentralized peer-to-peer system to verify transactions, which meant that people could exchange goods and services electronically, and anonymously, without having to rely on third parties like banks. Its medium of exchange, the bitcoin, was an invented currency that people could earn—or, in Bitcoin’s jargon, “mine”—by lending their computers’ resources to service the needs of the Bitcoin network. Once in existence, bitcoins could also be bought and sold for dollars or other currencies on online exchanges.

Golden Cyberfetters. Virtualcurrencyschemes201210en. Bitcoin currency value reaches record high of $147 before plunging down. Bitcoin's usefulness is its lack of the need for a central bank. Photograph: Zach Copley/Flickr/CC The value of individual Bitcoins has hit a record high of almost $147 as interest in the cryptographic currency, which has no central issuing bank, has exploded. Though the value fell back later on Wednesday to $117, the value of all Bitcoins in circulation is approaching $1.4bn. Both the volume being traded and the amounts being paid have suddenly risen, apparently as interest in the system has been spiked by the banking crisis in Cyprus – which had the spillover effect of making people in some southern European countries worry that their banking deposits might not be safe. Some are thought to have converted that money into Bitcoins, driving a rapid rise in the apparent value of the "coins" – actually cryptographic solutions to complex equations.

Avec Bitcoin, payer et vendre sans les banques. Bitcoin. The Demographics Of Bitcoin. With the growing popularity and perhaps relevance of a globally decentralized currency system in a world adrift in fiat devaluation death-matches, it is perhaps interesting to understand just who these Bitcoin'ers are? The ongoing survey of Bitcoin users (here) has some intriguing results already: The 'average Bitcoin user' is male (96%), 32.7 years old, libertarian / anarcho-capitalist (37%), non-religious (61%), with a full time job (43%), and is in a relationship (56%). The biggest motivation for new users are curiosity, profit, and politics; and 39% of users do not drink, smoke, gamble, or take drugs. Just over half of users have mined bitcoins and the greatest community fear for Bitcoin is “regulatory/legal intervention” followed by ”reputation problems”. Overall more people seem to find Bitcoin intellectually rewarding (70% have learned more about cryptography) than socially rewarding (22% have made friends).

Last November, in an act of sheer monetary desperation, the ECB issued an exhaustive, and quite ridiculous, pamphlet titled "Virtual Currency Schemes" in which it mocked and warned about the "ponziness" of such electronic currencies as BitCoin. Why a central bank would stoop so "low" to even acknowledge what no "self-respecting" (sic) PhD-clad economist would even discuss, drunk and slurring, at cocktail parties, remains a mystery to this day.

However, that it did so over fears the official artificial currency of the insolvent continent, the EUR, may be becoming even more "ponzi" than the BitCoins the ECB was warning about, was clear to everyone involved who saw right through the cheap propaganda attempt.
