Ethereum has recently created a new standard called the ERC721 token for tracking unique digital assets. One of the biggest use cases currently for such tokens is digital collectibles, as the infrastructure allows for people to prove ownership of scarce digital goods. Many games are currently being built using this technology, such as the overnight hit CryptoKitties, a game where you can collect and breed digital cats.

EthereumPrice.org was developed by Ether0x in March 2016 to allow users to easily track the price of Ethereum both historically and in real-time. The platform has since evolved to include several fiat currencies (EUR, GBP, JPY and others) as well as price data for a number of Ethereum ERC20 tokens and other blockchain currencies. More recently, prediction data from Augur was also added to provide insight into the future price expectations of the Ether market. Price data is currently sourced from multiple exchanges with the weighted average price of these assets being calculated by CryptoCompare.com. For more details on the weighted average calculation, see our FAQ. 

The price of bitcoins has gone through cycles of appreciation and depreciation referred to by some as bubbles and busts.[159] In 2011, the value of one bitcoin rapidly rose from about US$0.30 to US$32 before returning to US$2.[160] In the latter half of 2012 and during the 2012–13 Cypriot financial crisis, the bitcoin price began to rise,[161] reaching a high of US$266 on 10 April 2013, before crashing to around US$50. On 29 November 2013, the cost of one bitcoin rose to a peak of US$1,242.[162] In 2014, the price fell sharply, and as of April remained depressed at little more than half 2013 prices. As of August 2014 it was under US$600.[163] During their time as bitcoin developers, Gavin Andresen[164] and Mike Hearn[165] warned that bubbles may occur.

Like web browsers give access and help people navigate the internet, Mist provides a portal into the world of decentralized blockchain applications.
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.
من منظور المنقبين فإن سعر البيتكوين الحالي أقل بكثير مما يجب عليه أن يكون، ولهذا ستجد أنه لا رغبة لديهم في بيع العُملات التي بحوزتهم بأسعار مُنخفضة لأنهم قد استخدموا كميات هائلة من الكهرباء لإنتاجها، إضافة إلى الاستثمار في عتاد خاص للقيام بذلك. الوضع سيزداد سوءا بالنسبة إليهم ما لم ينخفض عدد المُنقبين بشكل مُعتبر، حيث أن عدد العُملات التي سيتم إنتاجها ستنخفض إلى النصف كل 4 سنوات. في المقابل، تم إنتاج كميات كبيرة من البيتكوينات بشكل رخيص جدا في بدايات العُملة لما كان عدد المُنقبين قليلا ولما كان عامل “الصعوبة” hardness منخفضا جدا، وبالتالي حاجة إلى كهرباء أقل، هذا الأمر خلق حالة من اللاتوازن داخل شبكة العُملة، حيث بإمكان أصحاب البيتكوينات القديمة بيع عُملاتهم دون تسجيل خسائر مُقارنة بمن انضموا إلى جبهة المُنقبين مؤخرا.
“A DAO consists of one or more contracts and could be funded by a group of like-minded individuals. A DAO operates completely transparently and completely independently of any human intervention, including its original creators. A DAO will stay on the network as long as it covers its survival costs and provides a useful service to its customer base” Stephen Tual, Slock.it Founder, former CCO Ethereum.
Various journalists,[205][210] economists,[211][212] and the central bank of Estonia[213] have voiced concerns that bitcoin is a Ponzi scheme. In April 2013, 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."[214] A July 2014 report by the World Bank concluded that bitcoin was not a deliberate Ponzi scheme.[215]:7 In June 2014, the Swiss Federal Council[216]:21 examined the concerns that bitcoin might be a pyramid scheme; it concluded that, "Since in the case of bitcoin the typical promises of profits are lacking, it cannot be assumed that bitcoin is a pyramid scheme." In July 2017, billionaire Howard Marks referred to bitcoin as a pyramid scheme.[217]
To be accepted by the rest of the network, a new block must contain a proof-of-work (PoW).[75] The system used is based on Adam Back's 1997 anti-spam scheme, Hashcash.[85][4] The PoW requires miners to find a number called a nonce, such that when the block content is hashed along with the nonce, the result is numerically smaller than the network's difficulty target.[7]:ch. 8 This proof is easy for any node in the network to verify, but extremely time-consuming to generate, as for a secure cryptographic hash, miners must try many different nonce values (usually the sequence of tested values is the ascending natural numbers: 0, 1, 2, 3, ...[7]:ch. 8) before meeting the difficulty target.
تُعتبر بيتكوين عُملة معمّاة (بالإنجليزية: cryptocurrency) ويُقصد بذلك أنها تعتمد بشكل أساسي على مبادئ التشفير في جميع جوانبها، كما أنها تُعتبر أيضا العُملة الأولى من نوعها والأكثر شهرة وانتشارًا لكن رغم ذلك ليست العُملة التشفيرية الوحيدة الموجودة على شبكة الإنترنت حاليًا. حيث يتوفر ما يزيد عن 60 عُملة تشفيرية مُختلفة[6] منها 6 عُملات يُمكن وصفها بالرئيسية [7] وذلك اعتمادًا على عدد المُستخدمين وبنية كل شبكة، إضافة إلى الأماكن التي يُمكن استبدال وشراء هذه العُملات التشفيرية مُقابل عُملات أخرى. جميع العُملات التشفيرية الحالية مبنية على مبدأ عمل عُملة بيتكوين نفسها باستثناء عُملة Ripple [8]، وبما أن عُملة بيتكوين مفتوحة المصدر فإنه من المُمكن استنساخها وإدخال بعض التعديلات عليها ومن ثم إطلاق عُملة جديدة.

مقارنة بأجزاء أخرى من العالم بدأت الدول العربية في وقت متأخر نسبيا باستخدام بيتكوين حيث أعلن عن قبول هذه العملة لأول مرة في الأردن في بار شاي في العاصمة عمان. وتلى ذلك مطعم بيتزا وصراف آلي في دبي[15] ومن ثم شركة انظمه معلومات في فلسطين[16] كما أصبح سوق السفير من أوئل الاسواق في الكويت و الشرق الأوسط التي تقبل البتكوين في تعاملته [17]. اما بالنسبة للعملة الالكترونية في المشهد الاعلامي العربي فقد بدأت مؤخرا فقرات اخبارية تتحدث عنها ولو بشكل طفيف كما بدأت مواقع متخصصة في اخبار بيتكوين مثل موقع بيتكوين نيوز عربية [18] التابع لمجموعة اعلامية كبيرة،وعلى مستوى الشبكات الاجتماعية يمكن للمستخدمين في الشرق الأوسط وشمال افريقيا التفاعل على موقع askbitcoiner [19] الذي يعتبر أول شبكة اجتماعية للعملة الرقمية في العالم العربي حيث يمكن العثور على الاجوبة للاستفسارات حول العملة الرقمية وتقنية البلوك شاين. وعلى صعيد الشركات اللي توفر خدمات للبيتكون بالوطن العربي فمنهما يلو (بالإنجليزية: Yellow) و بت اويسس (بالإنجليزية: BitOasis) المؤسستان في دبي. بالإضافة إلى بت فلس (بالإنجليزية: BitFils) المؤسسة في الكويت. ويمكن شراء وتداول البيتكوين محليا عن طريق localbitcoins.com .
The first wallet program, simply named Bitcoin, and sometimes referred to as the Satoshi client, was released in 2009 by Satoshi Nakamoto as open-source software.[11] In version 0.5 the client moved from the wxWidgets user interface toolkit to Qt, and the whole bundle was referred to as Bitcoin-Qt.[107] After the release of version 0.9, the software bundle was renamed Bitcoin Core to distinguish itself from the underlying network.[108][109]
