Bitcoin (kurz: BTC) ist eine digitale Währung, die elektronisch geschaffen ( gemined) und verwahrt wird. Anders als der Euro oder der Dollar werden Bitcoins. Aufgrund vielfach aufgetretener Probleme im Bereich Informationssicherheit werben einige Börsen mit verbesserter Sicherheit und bieten teilweise Zertifizierungen ihrer Websites, Zwei-Faktor-Authentifizierungsverfahren , Haftung für verlorene Einlagen bis hin zu einer regulären Einlagensicherung für Fiat-Geldbeträge. Bitcoin's Blockchain-Infrastruktur hat dabei eine revolutionäre Methode der Speicherung finanzieller Daten eingeführt, die durch völlige Transparenz und Zugänglichkeit besticht, durch Co-Entwicklung mit Open-Source Code entstanden ist und keiner einzelnen Person oder Instanz gehört.

    High price volatility and transaction fees make paying for small retail purchases with bitcoin impractical, according to economist Kim Grauer.

    However, bitcoin continues to be used for large-item purchases on sites such as Overstock. Bitcoins can be bought on digital currency exchanges.

    Bitcoin has not gained acceptance for use in international remittances despite high fees charged by banks and Western Union who compete in this market.

    Unlike bitcoin, these competitors accept and dispense cash and do not require the use of the Internet which is a distinct advantage in lower income countries.

    In , the National Australia Bank closed accounts of businesses with ties to bitcoin, [] and HSBC refused to serve a hedge fund with links to bitcoin.

    Plans were announced to include a bitcoin futures option on the Chicago Mercantile Exchange in The Winklevoss twins have purchased bitcoin.

    Forbes named bitcoin the best investment of The price of bitcoins has gone through cycles of appreciation and depreciation referred to by some as bubbles and busts.

    According to Mark T. However, the use of bitcoin can be criminalized, and shutting down exchanges and the peer-to-peer economy in a given country would constitute a de facto ban.

    Regulations and bans that apply to bitcoin probably extend to similar cryptocurrency systems. According to the Library of Congress , an "absolute ban" on trading or using cryptocurrencies applies in eight countries: Commodity Futures Trading Commission has issued four "Customer Advisories" for bitcoin and related investments.

    Securities and Exchange Commission has also issued warnings. A May "Investor Alert" warned that investments involving bitcoin might have high rates of fraud, and that investors might be solicited on social media sites.

    Academic research published in the Journal of Monetary Economics concluded that price manipulation occurred during the Mt Gox bitcoin theft and that the market remains vulnerable to manipulation.

    Research by John M. Griffin and Amin Shams in suggests that trading associated with increases in the amount of the Tether cryptocurrency and associated trading at the Bitfinex exchange account for about half of the price increase in bitcoin in late The Bank for International Settlements summarized several criticisms of bitcoin in Chapter V of their annual report.

    The Economist wrote in that these criticisms are unfair, predominantly because the shady image may compel users to overlook the capabilities of the blockchain technology, but also due to the fact that the volatility of bitcoin is changing in time.

    Bitcoin, along with other cryptocurrencies , has been identified as economic bubble by at least eight Nobel Memorial Prize in Economic Sciences laureates, including Robert Shiller , [] Joseph Stiglitz , [] and Richard Thaler.

    Bitcoin has been criticized for the amount of electricity consumed by mining.

    Various journalists, [] [] economists, [] [] and the central bank of Estonia [] have voiced concerns that bitcoin is a Ponzi scheme.

    In April , Eric Posner , a law professor at the University of Chicago , stated that "a real Ponzi scheme takes fraud; bitcoin, by contrast, seems more like a collective delusion.

    Senate held a hearing on virtual currencies in November Several news outlets have asserted that the popularity of bitcoins hinges on the ability to use them to purchase illegal goods.

    By regulating the abuses, you are going to regulate it out of existence. It exists because of the abuses. In , researchers at the University of Kentucky found "robust evidence that computer programming enthusiasts and illegal activity drive interest in bitcoin, and find limited or no support for political and investment motives".

    There were an estimated 24 million bitcoin users primarily using bitcoin for illegal activity.

    Die Schwierigkeit der Aufgabe wird im Netzwerk dynamisch so geregelt , dass im Mittel alle zehn Minuten ein neuer Block erzeugt wird.

    Der Proof-of-Work besteht bei Bitcoin darin, einen Hashwert zu finden, der unterhalb eines bestimmten Schwellwerts liegt.

    The central bank must be trusted not to debase the currency, but the history of fiat currencies is full of breaches of that trust. Banks must be trusted to hold our money and transfer it electronically, but they lend it out in waves of credit bubbles with barely a fraction in reserve.
