Ethereum was initially described in a white paper by Vitalik Buterin,[10] a programmer involved with Bitcoin Magazine, in late 2013 with a goal of building decentralized applications.[11][12] Buterin had argued that Bitcoin needed a scripting language for application development. Failing to gain agreement, he proposed development of a new platform with a more general scripting language.[4]:88

Ethereum is also being used as a platform to launch other cryptocurrencies. Because of the ERC20 token standard defined by the Ethereum Foundation, other developers can issue their own versions of this token and raise funds with an initial coin offering (ICO). In this fundraising strategy, the issuers of the token set an amount they want to raise, offer it in a crowdsale, and receive Ether in exchange. Billions of dollars have been raised by ICOs on the Ethereum platform in the last two years, and one of the most valuable cryptocurrencies in the world, EOS, is an ERC20 token.
Nigel Dodd argues in The Social Life of Bitcoin that the essence of the bitcoin ideology is to remove money from social, as well as governmental, control.[131] Dodd quotes a YouTube video, with Roger Ver, Jeff Berwick, Charlie Shrem, Andreas Antonopoulos, Gavin Wood, Trace Meyer and other proponents of bitcoin reading The Declaration of Bitcoin's Independence. The declaration includes a message of crypto-anarchism with the words: "Bitcoin is inherently anti-establishment, anti-system, and anti-state. Bitcoin undermines governments and disrupts institutions because bitcoin is fundamentally humanitarian."[131][130]

• عدم الإعتراف بها من قبل الجهات المُختصة: إستناداً إلى قول الإمام ابن تيمية: ’’الدراهم والدنانير لا تقصد لنفسها بل هي وسيلة إلى التعامل بها، ولهذا كانت أثمانا بخلاف سائر الأموال، فإن – هذه الاموال – المقصود الإنتفاع بها نفسها”. وفي وقتنا الحالى لا تعتمد تداول وإستثمار العُملات إلا بموجب إعتراف وموافقة من قبل الجهات المُختصة وعلى رأسها البنوك المركزية. وبحسب ما قُيل من قبل البنوك المركزية إنه لم يتم الإعتراف بعد بعُملات البيتكوين الإفتراضية كعٌملات صالحة للتداول والإستثمار. وطبقاً لذلك تُحرم عمليات التداول والإستثمار للبيتكوين.

Bitcoin is a digital currency, sometimes referred to as a cryptocurrency, best known as the world's first truly decentralized digital currency. Bitcoin is traded on a peer-to-peer basis with a distributed ledger called the Blockchain, and the Bitcoin exchange rate to the US Dollar and other major currencies is determined by supply and demand as with other global exchange rates. The traded value of Bitcoin has proven volatile through various booms and busts in demand. Ultimately, however, many see Bitcoin as a store of value against government-backed fiat currencies.
بيتكوين ليست العملة الافتراضية الوحيدة المتواجدة حاليًا في الأسواق الافتراضية. فقد برزت بفضل نجاحات ال بيتكوين ، مجموعة متنوعة من ما يسمى ب "altcoins" أو العملات الافتراضية البديلة ذات قيمة جيدة في الأسواق. أهم الفروقات بين البيتكوين وهذه العملات البديلة هي: البتكوين الأصعب في التعدين والأكثر غلاءً بينما العملات البديلة يمكن الحصول عليها عادةً بطريقة أسهل وأرخص، ويمكن أن يكون سعرها أكثر ثباتًا من سعر البتكوين ذات السعر المتقلب، كما أنّ الكثير من هذه العملات تم إنشاؤها لتلافي المشاكل الحاصلة في نظام بتكوين.[20] هذه لائحة بست عملات رقمية بديلة :

The unit of account of the bitcoin system is a bitcoin. Ticker symbols used to represent bitcoin are BTC[a] and XBT.[b][72]:2 Its Unicode character is ₿.[1] Small amounts of bitcoin used as alternative units are millibitcoin (mBTC), and satoshi (sat). Named in homage to bitcoin's creator, a satoshi is the smallest amount within bitcoin representing 0.00000001 bitcoins, one hundred millionth of a bitcoin.[2] A millibitcoin equals 0.001 bitcoins; one thousandth of a bitcoin or 100,000 satoshis.[73]

An official investigation into bitcoin traders was reported in May 2018.[177] The U.S. Justice Department launched an investigation into possible price manipulation, including the techniques of spoofing and wash trades.[178][179][180] Traders in the U.S., the U.K, South Korea, and possibly other countries are being investigated.[177] Brett Redfearn, head of the U.S. Securities and Exchange Commission's Division of Trading and Markets, had identified several manipulation techniques of concern in March 2018.
Despite the fallout from The DAO hack, Ethereum is moving forward and looking to a bright future. By providing a user-friendly platform that enables people to harness the power of blockchain technology, Ethereum is speeding up the decentralization of the world economy. Decentralized applications have the potential to profoundly disrupt hundreds of industries including finance, real estate, academia, insurance, healthcare and the public sector amongst many others.
Ethereum was officially with an unusually long list of founders. Anthony Di Iorio wrote "Ethereum was founded by Vitalik Buterin, Myself, Charles Hoskinson, Mihai Alisie, & Amir Chetrit (the initial 5) in December 2013. Joseph Lubin, Gavin Wood, & Jeffrey Wilke were added in early 2014 as founders." Formal development of the Ethereum software project began in early 2014 through a Swiss company, Ethereum Switzerland GmbH (EthSuisse).[13][14] The basic idea of putting executable smart contracts in the blockchain needed to be specified before the software could be implemented; this work was done by Gavin Wood, then chief technology officer, in the Ethereum Yellow Paper that specified the Ethereum Virtual Machine.[15] Subsequently, a Swiss non-profit foundation, the Ethereum Foundation (Stiftung Ethereum), was created as well. Development was funded by an online public crowdsale during July–August 2014, with the participants buying the Ethereum value token (ether) with another digital currency, bitcoin.

Wallets and similar software technically handle all bitcoins as equivalent, establishing the basic level of fungibility. Researchers have pointed out that the history of each bitcoin is registered and publicly available in the blockchain ledger, and that some users may refuse to accept bitcoins coming from controversial transactions, which would harm bitcoin's fungibility.[123] For example, in 2012, Mt. Gox froze accounts of users who deposited bitcoins that were known to have just been stolen.[124]
