2. After the hard bifurcation of etc, ETH came into being. The relationship between the three currencies is just like that between yen, won and US dollar

3. Hello, it's called EOS token. It's based on Ethereum token
EOS coin
EOS (Chinese Name: EOS, English Name: EOS, abbreviation: EOS) is a token based on Ethereum released for eos.io blockchain system. Blockone is a new blockchain architecture developed by blockone company, which aims to expand the performance of distributed applications. The goal of EOS project is to achieve a blockchain architecture similar to the operating system supporting applications. The architecture can provide account, identity authentication, database, asynchronous communication and program scheling on hundreds of CPUs or clusters. The ultimate form of this technology is a blockchain architecture, which can support millions of transactions per second, and ordinary users do not need to pay for the use of the blockchain
function of EOS token
the current form of EOS cryptocurrency belongs to ERC 20 smart contract token on Ethereum blockchain. EOS ERC 20 token will be converted into the cryptocurrency available in EOS system 1:1 after the formal launch of EOS blockchain. The EOS system is expected to release the test network in August 2017, and it is expected to take one year for the main network of EOS blockchain to go online. The following application scenarios are introced after the EOS blockchain is officially launched
EOS cryptography currency has three main application scenarios: bandwidth and log storage (hard disk); Calculation and calculation reserve (CPU); State memory (RAM)
both instantaneous and long-term components consume bandwidth and computation. The blockchain system will maintain logs of all messages, which will be downloaded and stored by all complete nodes. With log information, the state of all applications can be reconstructed
the specific application scenario of EOS cryptography currency can be explained as:
receiver payment: customers purchase specific procts from the business, and the sales revenue of these procts will be used to pay the business cost, so as to avoid customers paying for the use of blockchain directly, and will not restrict or prevent enterprises from determining the monetization strategy of their procts
authorization capability: if a blockchain is developed by using EOS software system and its token is held by a ticket holder, it may not need to consume all or part of the available bandwidth immediately. Such a holder can choose to give or rent the unused bandwidth to others
separate transaction costs from token value: if the application owner holds a corresponding amount of tokens, the application can continue to run in a fixed state and bandwidth usage. Developers and users are not affected by price fluctuations in the token market, so they are not price dependent
block reward: each time a block is generated, the eos.io system will reward the block generator with a new token. The system may be configured to limit the reward cap for block procers, so that the total annual increase in token supply does not exceed 5%
community welfare applications: users can choose three community welfare applications, also known as smart contracts. These smart contracts will collect tokens based on the proportion of votes each application receives from the token holder. The elected application or smart contract can be replaced by the smart contract of the newly elected application or token holder
What are the technical advantages of EOS
1. EOS creates a developer friendly underlying platform of blockchain, which is similar to the operating system of blockchain. It has powerful performance, can support multiple applications running at the same time, and can support multiple programming languages at the same time. It provides developers with underlying moles to lower the development threshold, just like Microsoft's windows. Do you think Microsoft is worth money
2. EOS solves the problems of delay and data throughput through parallel chain and dpos. EOS can achieve a processing capacity of one million per second. At present, bitcoin has 7 transactions per second, while Ethereum has 30-40 transactions. This super power of EOS can hang bitcoin and Ethereum. For example, the recent cryptokitties | collect and breed digital cats! This is a very popular eth game. Only one game accounts for about 15% of eth's throughput. If there are seven or eight similar games at the same time, ETH will die. It's scary to think about it. Eth, which can't expand bandwidth, will have great challenges in throughput, and EOS can solve the above problems.

5. They are all excellent digital currencies. We recommend the coin easy platform, support RMB direct recharge purchase, recharge withdrawal and instant account arrival!

6. The dragon is a mythical creature typically depicted as a large and powerful serpent or other reptile, with magical or spiritual qualities. Mythological creatures possessing some or most of the characteristics typically associated with dragons are common throughout the world's cultures.

Dragons are commonly portrayed as serpentine or reptilian, hatching from eggs and possessing long, typically scaly, bodies; they are sometimes portrayed as having large eyes, a feature that is the origin for the word for dragon in many cultures, and are often (but not always) portrayed with wings and a fiery breath. Some dragons do not have wings at all, but look more like long snakes.

Although dragons (or dragon-like creatures) occur commonly in legends around the world, different cultures have perceived them differently. Chinese dragons (Simplified Chinese: 龙; Traditional Chinese: 龙; pinyin: lóng), and Eastern dragons generally, are usually seen as benevolent, whereas European dragons are usually malevolent (there are of course exceptions to these rules). Malevolent dragons also occur in Persian mythology (see A Dahaka) and other cultures.

Dragons are often held to have major spiritual significance in various religions and cultures around the world. In many Eastern and Native American cultures dragons were, and in some cultures still are, revered as representative of the primal forces of nature and the universe. They are associated with wisdom—often said to be wiser than humans—and longevity. They are commonly said to possess some form of magic or other supernormal power, and are often associated with wells, rain, and rivers. In some cultures, they are said to be capable of human speech.

Dragons are very popular characters in fantasy literature, role-playing games and video games today.

The term dragoon, for infantry that move around by horse, yet still fight as foot soldiers, is derived from their early firearm, the "dragon", a wide-bore musket that spat flame when it fired, and was thus named for the mythical beast.

[edit] Symbolism
In medieval symbolism, dragons were often symbolic of apostasy and treachery, but also of anger and envy, and eventually symbolised great calamity. Several heads were symbolic of decadence and oppression, and also of heresy. They also served as symbols for independence, leadership and strength. Many dragons also represent wisdom; slaying a dragon not only gave access to its treasure hoard, but meant the hero had bested the most cunning of all creatures. In some cultures, especially Chinese, or around the Himalayas, dragons are considered to represent good luck.

Joseph Campbell in the The Power of Myth viewed the dragon as a symbol of divinity or transcendence because it represents the unity of Heaven and Earth by combining the serpent form (earthbound) with the bat/bird form (airborne).

Dragons embody both male and female traits as in the example from Aboriginal myth that raises baby humans to althood training them for survival in the world (Littleton, 2002, p. 646). Another contrast in the way dragons are portrayed is their ability to breathe fire but live in the ocean--water and fire together. And like in the quote from Joseph Campbell above, they also include the opposing elements of earth and sky. Dragons represent the joining of the opposing forces of the cosmos.

Yet another symbolic view of dragons is the Ouroborus, or the dragon encircling and eating its own tail. When shaped like this the dragon becomes a symbol of eternity, natural cycles, and completion.

[edit] In Christianity
The Latin word for a dragon, draco (genitive: draconis), actually means snake or serpent, emphasizing the European association of dragons with snakes. The Medieval Biblical interpretation of the Devil being associated with the serpent who tempted Adam and Eve, thus gave a snake-like dragon connotations of evil. Generally speaking, Biblical literature itself did not portray this association (save for the Book of Revelation, whose treatment of dragons is detailed below). The demonic opponents of God, Christ, or good Christians have commonly been portrayed as reptilian or chimeric.

In the Book of Job Chapter 41, the sea monster Leviathan, which has some dragon-like characteristics.

In Revelation 12:3, an enormous red beast with seven heads is described, whose tail sweeps one third of the stars from heaven down to earth (held to be symbolic of the fall of the angels, though not commonly held among biblical scholars). In most translations, the word "dragon" is used to describe the beast, since in the original Greek the word used is drakon (δράκον).

In iconography, some Catholic saints are depicted in the act of killing a dragon. This is one of the common aspects of Saint George in Egyptian Coptic iconography [1], on the coat of arms of Moscow, and in English and Catalan legend. In Italy, Saint Mercurialis, first bishop of the city of Forlì, is also depicted slaying a dragon.[2] Saint Julian of Le Mans, Saint Veran, Saint Crescentinus, and Saint Leonard of Noblac were also venerated as dragon-slayers.

However, some say that dragons were good, before they fell, as humans did. Also contributing to the good dragon argument in Christianity is the fact that, if they did exist, they were created as were any other creature, as seen in Dragons In Our Midst, a contemporary Christian book series by author Bryan Davis.

[edit] Chinese zodiac
The years 1916, 1928, 1940, 1952, 1964, 1976, 1988, 2000, 2012, 2024, 2036, 2048, 2060 are considered the Year of the Dragon in the Chinese zodiac.

The Chinese zodiac purports that people born in the Year of the Dragon are healthy, energetic, excitable, short-tempered, and stubborn. They are also supposedly honest, sensitive, brave, and inspire confidence and trust. The Chinese zodiac purports that Dragon people are the most eccentric of any in the eastern zodiac. They supposedly neither borrow money nor make flowery speeches, but tend to be soft-hearted which sometimes gives others an advantage over them. They are purported to be compatible with Rats, Snakes, Monkeys, and Roosters.

[edit] In East Asia
Main article: Chinese dragon
Main article: Vietnamese dragon
Dragons are commonly symbols of good luck/health in some parts of Asia, and are also sometimes worshipped. Asian dragons are considered as mythical rulers of weather, specifically rain and water, and are usually depicted as the guardians of flaming pearls.

In China, as well as in Japan and Korea, the Azure Dragon is one of the Four Symbols of the Chinese constellation, representing spring (season), the element of Wood and the east. Chinese dragons are often shown with large pearls in their grasp, though some say that it is really the dragon's egg. The chinese believed that the dragons lived under water most of the time, and would sometimes offer rice as a gift to the dragons. The dragons were not shown with wings like the European dragons because it was believed they could fly using magic.

A Yellow dragon (Huang long) with five claws on each foot, on the other hand, symbolize imperial authority in China, and indirectly the Chinese people as well. Chinese people often use the term "Descendants of the Dragon" as a sign of ethnic identity. The dragon is also the symbol of royalty in Bhutan (whose sovereign is known as Druk Gyalpo, or Dragon King).

In Vietnam, the dragon (Vietnamese: rồng) is the most important and sacred symbol. According to the ancient creation myth of the Kinh people, all Vietnamese people are descended from dragons through Lạc Long Quân, who married Âu Cơ, a fairy. The eldest of their 100 sons founded the first dynasty of Hùng Vương Emperors.

A naga guarding the Temple of Wat Sisaket in Viang Chan, LaosWhere the original concept of a dragon came from is unknown, as there is no accepted scientific theory or any evidence to support that dragons actually exist or have existed.

Some believe that the dragon may have had a real-life counterpart from which the legends around the world arose — typically dinosaurs or other archosaurs are mentioned as a possibility — but there is no physical evidence to support this claim, only alleged sightings collected by cryptozoologists. In a common variation of this hypothesis, giant lizards such as Megalania are substituted for the living dinosaurs. Some Creationists hold that dragons are just an exaggerated depiction of what we now call dinosaurs and that humans and dinosaurs (dragons) did co-exist.[1] All of these hypotheses are widely considered to be pseudoscience or myth.

Dinosaur fossils were once thought of as "dragon bones" — a discovery in 300 BC in Wucheng, Sichuan, China, was labeled as such by Chang Qu.[2] It is unlikely, however, that these finds alone prompted the legends of flying monsters, but may have served to reinforce them.

Herodotus, often called the "father of history", visited Judea c.450 BC and wrote that he heard of caged dragons in nearby Arabia, near Petra, Jordan. Curious, he travelled to the area and found many skeletal remains of serpents and mentioned reports of flying serpents flying from Arabia into Egypt but being fought off by Ibises Histories.
