Pourquoi les banques entrent en guerre contre le Bitcoin Pourquoi les banques entrent en guerre contre le Bitcoin Par Mark Maunder, depuis Seattle, États-Unis. Un article traduit par le Framablog, sous licence CC. Et si nous vivions dans un monde où toutes les transactions se faisaient de personne à personne et ne coûtaient quasiment rien ? Et si nous vivions dans un monde où la valeur de l’argent épargné augmentait petit à petit, non pas grâce aux intérêts, mais simplement parce que, avec le temps qui passe, vous pouvez acheter plus de trucs avec la même somme ? Et si s’endetter devenait une très mauvaise idée parce que, si vous détenez 10 unités de monnaie aujourd’hui, et que la valeur de celle-ci augmente lentement, alors vous devrez graduellement de plus en plus d’argent ?

While it is true that local communities have, in the past, generated successful communitarian currencies (that enabled them to improve welfare in their midst, especially at a time of acute economic crises), there can be no de-politicised currency capable of ‘powering’ an advanced, industrial society.

Published time: April 27, 2013 10:39 AFP Photo / George Frey Canadians using bitcoins, the decentralized crypto-currency that recently went mainstream, must report their incomes and pay taxes as with other earnings, Canada's Revenue Agency (CRA) confirmed following a media request. The issue was clarified in response to a letter by the Canadian Broadcasting Corporation (CBC) ahead of the country's tax season. Two separate tax rules are applicable to the electronic currency, CRA spokesperson Philippe Brideau told CBC in an email.

Bitcoin and the dangerous fantasy of ‘apolitical’ money The Crash of 2008 has infused our societies with enormous scepticism on the role of the authorities, both government and Central Banks. It is quite natural that many dream of a currency that politicians, bankers and central bankers cannot manipulate; a currency of the people by the people for the people. Bitcoin has emerged as the great white hope of something of the sort. Alas, the hope it brings to many people’s hearts and minds is false. And the reason is simple: While it is true that local communities have, in the past, generated successful communitarian currencies (that enabled them to improve welfare in their midst, especially at a time of acute economic crises), there can be no de-politicised currency capable of ‘powering’ an advanced, industrial society.

Bad news for all the hackers and libertarians out there supporting the bitcoin movement: Your favorite currency seems to have fallen into the wrong hands. Venture capitalists Tyler and Cameron Winklevoss claim to own about 1 percent of all bitcoins in existence, about $11 million worth. It's utterly unsurprising that the Winklevoss twins, who are famous for suing Mark Zuckerberg over the idea for Facebook, have decided to announce their investment in bitcoins at the height of public mania over the digital currency.

By Brett Wolf Wed Jun 8, 2011 11:17am EDT ST. LOUIS (Thomson Reuters Accelus) - Two senators are pressing federal authorities to crack down on an online black market and "untraceable" digital currency known as Bitcoins after reports that they are used to buy illegal drugs anonymously. Democratic Senators Charles Schumer of New York and Joe Manchin of West Virginia wrote to Attorney General Eric Holder and Drug Enforcement Administration head Michele Leonhart in a letter that expressed concerns about the underground website "Silk Road" and the use of Bitcoins to make purchases there.

Bitcoin : la monnaie virtuelle flambe, le monde réel s’inquiète | Rue89 Eco Dans Second Life, on pouvait faire construire sa maison avec des Linden dollars. Mais la monnaie virtuelle tendance aujourd’hui est le bitcoin. Celle-ci intéressait peu les banquiers réels... jusqu’à ce qu’elle flambe, de 4,15 euros en février 2011 à 109,91 euros le 3 avril 2013. Le bitcoin est accusé désormais d’entretenir une bulle spéculative. Il faut dire que Satoshi Nakamoto (pseudo du concepteur de cette monnaie virtuelle) – qui en a livré tous les secrets en open source dans ce document [en anglais, PDF] – a décidé de limiter le nombre de bitcoins en circulation à 21 millions. Versant Web du Sol-Violette, monnaie solidaire en pleine expansion, le bitcoin a quelque chose d’utopique, comme nous l’expliquait le riverain lv, roboticien utopiste, sous le témoignage d’un « vendu de banquier » : Bitcoin : la monnaie virtuelle flambe, le monde réel s’inquiète | Rue89 Eco

Le bitcoin fait pour le moment beaucoup de bruit. Certains y voient une révolution planétaire, d’autres une arnaque comme une autre. Nombreux sont ceux qui l’appellent une pyramide de Ponzi, un terme que tout le monde se targue d’utiliser mais que personne ne se serait attendu à trouver en dehors du menu d’une pizzeria avant 2008. Plutôt que de démonter cette affirmation en pointant les différences entre Bitcoin et une pyramide de Ponzi ou en arguant que, selon cette même définition, tout marché financier (y compris l’euro ou le dollar) est une arnaque de Ponzi, essayons de nous mettre dans la tête d’un partisan du bitcoin. Qui peut croire au succès du bitcoin et surtout pourquoi ? Un bitcoin dans la tête Un bitcoin dans la tête
Much like the New York Stock Exchange, Bitcoin exchanges have suffered from their first massive loss -- a virtual "Black Friday", so to speak.

Bitcoin is not decentralized : Inside 1712B Bitcoin was designed by Satoshi Nakamoto, and the primary client is developed by a bunch of folks at bitcoin.org. Do you care who these people are? In theory, you shouldn’t: all they do is develop an open source client for an open source protocol. Anyone else can develop their own client (and some people have) and no one, save the agreement of everyone in the Bitcoin network, can change the protocol.

Bitcoin: de la révolution monétaire au Ponzi 2.0 Derrière l'idée révolutionnaire, libertarienne et anti-banques Bitcoin ne fait que reproduire un système injuste. Toucher aux règles monétaires n’a rien d’anecdotique. Lorsque nous dépensons, que nous travaillons, tous les jours, ce que nous faisons a un rapport avec la monnaie, sans même que nous y pensions. Que se passe-t-il alors lorsque des geeks créent une monnaie universelle, décentralisée, sécurisée, anonyme ? Lorsque ceux-ci peuvent faire du commerce en dehors de toute forme de contrôle, qu’il soit bancaire, étatique, ou fiscal ? En apparence, une révolution.
Yesterday I questioned whether we should expect demand for Bitcoins to be stable over the long run. Today I want to look at the supply side. A constrained supply of money is important to a currency’s stability. One of Bitcoin’s key selling points is that the number of Bitcoins issued will never exceed 21 million. But this promise isn’t credible. Bitcoin’s Collusion Problem | Bottom-up
In the first Bitcoin theft of its size, a user has lost 25,000 BTC — or nearly $487,749 at today’s market rates — to an unknown thief. While the Bitcoin community has always been quick to point out that it’s harder to forge a Bitcoin than to forge a dollar, it’s quite easy to take someone else’s Bitcoins: all you have to do is gain access to their computer’s hard drive. Once you’re in, stealing Bitcoins is easier than taking a wallet in the real world, and there’s no recourse for getting them back. That said, it is possible to verify the movement of funds to ensure complainants are telling the truth due to Bitcoin’s public nature — services such as BlockExplorer allow users to see every transaction that has ever occurred through the network. The receiving account in this case, for instance, can be seen here. As a decentralized network with no authority and no identities attached to the addresses used to send and receive Bitcoins, once Bitcoins are stolen they’re as good as gone.
