Genève: Une nouvelle monnaie virtuelle a été lancée mardi à Genève, avec pour ambition de concurrencer le bitcoin en adossant sa valeur sur les cours du pétrole, une première dans le secteur en développement des cryptomonnaies.La devise, baptisée "bilur" et créée par la société londonienne R FinTech, vise à offrir une option alternative aux utilisateurs hésitants devant les fluctuations sauvages des monnaies numériques."C'est la première cryptomonnaie avec une vraie valeur", a déclaré Ignacio M. Ozcariz, PDG de la société, lors d'une conférence de presse.Pour le lancement de cette monnaie, R FinTech et ses partenaires ont acheté un million de barils de pétrole, stockés au Texas.A chaque bilur correspond la valeur d'une tonne - soit 6,5 barils - au cours du jour, qui s'établit actuellement à (326 euros)."Aufur et à mesure du développement du bilur, davantage de pétrole sera acquis, ses réserves stockées se chiffrant en milliards de barils", précise le communiqué de presse.Contrairement aux devises physiques telles que l'euro ou le dollar, les cryptomonnaies comme le bitcoin ne dépendent d'aucune banque centrale: elles sont générées par des milliers d'ordinateurs dans le monde (un processus baptisé "minage"), et se vendent et s'achètent en ligne.Le bitcoin, au cours très volatil, est accepté comme moyen de paiement par de nombreux sites internet et même certains commerçants physiques.

Ses détracteurs lui reprochent toutefois de manquer de transparence et d'être l'instrument de trafics illégaux.Le cours du bitcoin a atteint récemment un plus haut de 1. alors qu'il ne valait que quelques cents lors de son lancement en 2009.Bilur vise à séduire une clientèle attirée par une monnaie virtuelle, mais qui se sentirait plus rassurée si elle était garantie par des biens tangibles, comme l'étalon or par exemple."Nousrestons une cryptomonnaie, nous ne faisons que la soutenir avec quelque chose de réel", a expliqué Usama al Ali, directeur du développement de R Fintech.menter via Prixdubaril via FacebookAjouter un Commentaire PrécédentSuivantUSB Bitcoin miners are available to buy, but they don’t really generate any significant profits.They’re a good choice if you just want to fool around with Bitcoin mining and miners like the Antminer S9, S7, S5, Antminer R4, SP20, and Avalon6 are too expensive for you.You should buy one to learn how mining works, but other than that don’t expect much!

If you are serious about making profit then check out better Bitcoin mining hardware.You can always check the profitability of a USB miner using our mining calculator.The Sapphire Block Erupters were the first Bitcoin USB miners.They have 330 MH/s of hash power which would net you less than $0.01 per month.It may be a good choice just to see how mining works, but like with most USB miners: do not expect to turn a profit.The GekkoScience miners is just slightly better than the original block erupters.It will net you about $0.15 per month, which is more than a dollar per year!ethereum kaufneThe company claims that the device runs completely silent.cnn dinero bitcoinIt works with just one USB port.The Avalon Nano 3 is a 3.6 GH/s miner, which will earn you about $1 per year.valore dei bitcoin

No fan is required and it just plugs into your USB port on any computer.The Bitmain AntRouter isn’t exactly a USB miner, but it is similar.It’s low cost, but with that you get a low GH/s at just 5.5 GH/s which is a little over $1 per year.Table of ContentsBitcoin USB Miners ComparisonASICMiner Block Erupter USB 330MH/s Sapphire MinerGekkoScience Compac USB Stick Bitcoin MinerAvalon Nano 3Bitmain Antrouter R1 Wifi Solo Bitcoin Miner21 Bitcoin ComputerMore Bitcoin Mining Hardware ASICs (None-USB) The plus side is it works as a wireless router, so you can do some mining while providing internet for all your devices.The 21 Bitcoin Computer isn’t the typical USB Bitcoin miner.bitcoin mystery solvedIt does, however, plugin to your computer via USB.ethereum explorerIn terms of $ / hash rate, it’s not a very good choice.But since it’s still technically a USB miner we have included it in this list.If you’re not impressed, we don’t blame you!litecoin price api

USB Bitcoin mining was only profitable when Bitcoin was in its early years.If you just want bitcoins then invest in serious mining hardware or just buy bitcoins.Tunisia is using elements of a decentralised ledger system to replicate the success of mobile money system MPesa, with a more interoperable e-cash protocol backed by La Poste Tunisienne and the country's central bank.Monetas, the software provider in this case, told IBTimes: "The Monetas platform offers a future proof architecture which could enable La Poste Tunisienne to one day connect to open standard distributed ledger systems such as the bitcoin blockchain.However there are no plans today to move in that direction yet."TheBlockchain technology allows a country to develop a totally new and decentralized e-government vision.As the specific applications are not known or available today a future proof design at least ensures future compatibility."NorthAfrican countries have not been as well served by e-money as Sub-Saharan counterparts like Kenya and Zimbabwe.Vitus Ammann, chief marketing officer, Monetas, said the apparent success of MPesa belies an interoperability problem which the Monetas system would address."This

is currently the problem in the African countries because mobile money is issued by the different telecom operators and if you are a user of a different telecom company you cannot actually deal with each other because they are all separate systems."Oursystem is going to solve that problem with an easy to achieve interoperability."Mobileoperators run centralised systems where all the funds are stored, making them like financial intermediaries, he added.He said this was the first stage of a digital cash programme which could next year interoperate with or integrate Bitcoin, depending on the regulatory climate."Twelvemonths down the road we expect to use multi-signature system protocol to interoperate directly with the Bitcoin blockchain," he saidMonetas has teamed up with La Poste Tunisienne and Tunisian startup DigitUs to ramp up mobile money in the country which it is called eDinar-Plus.Ammann said: "La Poste Tunisienne has a licence from the national bank to issue digital money tagged to the national currency.

Today that is in the form of eDinar which is a kind of a card based online payment tool and now with our system they will issue that on mobile phones as well.Ammann said DigitUs, La Poste and the central bank will act as a notaries handling the transactions, and over time more notaries will be pooled together working in parallel in a distributed ledger model.He said: "What we are launching today is basically the first level of that - where you have one notary which is managed by the public/private ownership of La Poste so that you get this distributed ledger system."Theaim is for mobile operators to join the system so that different players in the market can all work on the same platform.Ammann also said the Monetas model would work out cheaper than mobile money systems like MPesa."Theminimum fees which Mpesa and similar systems are charging are something like 20 to 30 cents a transaction.The average transaction size in these countries is $2 - $3, so a merchant has to pay 10% or 20 % of transaction in fees."In
