编辑比特币[1]可以用来兑现，可以兑换成大多数国家的货币。
使用者可以用比特币购买一些虚拟物品，比如网络游戏当中的衣服、帽子、装备等，只要有人接受，也可以使用比特币购买现实生活当中的物品。
比特币与其他虚拟货币最大的不同，是其总数量非常有限，具有极强的稀缺性。
该货币系统曾在4年内只有不超过1050万个，之后的总数量将被永久限制在2100万个。
虚拟货币---比特币的概念最初由中本聪在2009年提出。
比特币也用于称bitcoin，根据中本聪的思路设计发布的开源软件以及建构其上的P2P网络。
与大多数货币不同，比特币不依赖于特定的中央发行机构，使用遍布整个P2P 网络节点的分布式数据库来记录货币的交易，并使用密码学的设计来确保货币流通各个环节安全性。
例如，比特币只能被它的真实拥有者使用，而且仅仅一次，支付完成之后原主人即失去对该份额比特币的所有权。
[1]发展历程2008年爆发全球金融危机，当时有人用“中本聪”的化名发比特币表了一篇论文，描述了比特币的模式。
2009年，不受央行和任何金融机构控制的比特币诞生。
[2]比特币是一种“电子货币”，由计算机生成的一串串复杂代码组成，新比特币通过预设的程序制造，随着比特币总量的增加，新币制造的速度减慢，直到2140年达到2100万个的总量上限，被挖出的比特币总量已经超过1200万个。
[2]和法定货币相比，比特币没有一个集中的发行方，而是由网络节点的计算生成，谁都有可能参与制造比特币，而且可以全世界流通，可以在任意一台接入互联网的电脑上买卖，不管身处何方，任何人都可以挖掘、购买、出售或收取比特币，并且在交易过程中外人无法辨认用户身份信息。
[2]每当比特币进入主流媒体的视野时，主流媒体总会请一些主流经济学家分析一下比特币。
早先，这些分析总是集中在比特币是不是骗局。
而现如今的分析总是集中在比特币能否成为未来的主流货币。
而这其中争论的焦点又往往集中在比特币的通缩特性上。
我们今天不妨就讨论一下比特币的通缩问题。
Disney Star Wars, Disney and myth-makingHow one company came to master the business of storytellingFROM a galaxy far, far away to a cinema just down the road: “The Force Awakens”, the newest instalment of the Star Wars saga, is inescapable this Christmas. The first Star Wars title since Lucasfilm, the owner of the franchise, was acquired by Disney in 2012 for $4.1 billion, it represents more than just the revival of a beloved science-fiction series. It is the latest example of the way Disney has prospered over the past decade from a series of shrewd acquisitions (see article). Having bought Pixar, Marvel and Lucasfilm, Disney has skilfullycapitalised on their intellectual property—and in so doing, cemented its position as the market leader in the industrialisation of mythology. Its success rests on its mastery of the three elements of modern myth-making: tropes, technology and toys.From Homer to Han SoloStart with the tropes. Disney properties, which include everything from “Thor” to “Toy Story”, draw on well-worn devices of mythic structure to give their stories cultural resonance. Walt Disney himself had an intuitive grasp of the power of fables. George Lucas, the creator of Star Wars, is an avid student of the work of Joseph Campbell, an American comparative mythologist who outlined the “monomyth” structure in which a hero answers a call, is assisted by a mentor figure, voyages to another world, survives various trials and emerges triumphant. Bothfilm-makers merrily plundered ancient mythology and folklore. The Marvel universe goes even further, directly appropriating chunks of Greco-Roman and Norse mythology. (This makes Disney's enthusiasm for fierce enforcement of intellectual-property laws, and the seemingly perpetual extension of copyright, somewhat ironic.)The internal mechanics of myths may not have changed much over the ages, but the technology used to impart them certainly has. That highlights Disney's second area of expertise. In Homer's day, legends were passed on in the form of dactylic hexameters; modern myth-makers prefer computer graphics, special effects, 3D projection, surround sound and internet video distribution,among other things. When Disney bought Lucasfilm it did not just acquire the Star Wars franchise; it also gained Industrial Light & Magic, one of the best special-effects houses in the business, whose high-tech wizardry is as vital to Marvel's Avengers films as it is to the Star Wars epics. And when Disney was left behind by the shift to digital animation, it cannily revitalised its own film-making brand by buying Pixar, a firm as pioneering in its field as Walt Disney had been in hand-drawn animation. Moreover, modern myths come in multiple media formats. The Marvel and Star Wars fantasy universes are chronicled in interlocking films, television series, books, graphic novels and video games. Marvel's plans are mapped out until the mid-2020s.But these days myths are also expected to take physical form as toys, merchandise and theme-park rides. This is the third myth-making ingredient. Again, Walt Disney led the way, licensing Mickey Mouse and other characters starting in the 1930s, and opening the original Disneyland park in 1955. Mr Lucas took cinema-related merchandise into a new dimension, accepting a pay cut as director in return for all the merchandising rights to Star Wars—a deal that was to earn him billions. Those rights now belong to Disney, and it is making the most of them: sales of “The Force Awakens” merchandise, from toys to clothing, are expected to be worth up to $5 billion alone in the coming year. In all, more than $32 billion-worth of Star Wars merchandise has been sold since 1977, according to NPD Group, a market-research firm. Even Harry Potter and James Bond are scruffy-looking nerf-herders by comparison.Those other franchises are reminders that Disney's approach is not unique. Other studios are doing their best to imitate its approach. But Disney has some of the most valuable properties and exploits them to their fullest potential. It is particularly good at refreshing and repackaging its franchises to encourage adults to revisit their childhood favourites and, in the process, to introduce them to their own children. This was one reason why Pixar, whose films are known for their cross-generational appeal, was such a natural fit. Now the next generation is being introduced to Star Wars by their nostalgic parents. At the same time, Disney has extended its franchises by adding sub-brands that appeal to particular age groups: children's television series spun off from Star Wars, for example, or darker, more adult tales from the Marvel universe, such as the “Daredevil” and “Jessica Jones” series on.Do, or do not—there is no tryWhat explains the power of all this modern-day mythology? There is more to it than archetypal storytelling, clever technology and powerful marketing. In part, it may fill a void left by the decline of religion in a more secular world. But it also provides an expression for today's fears.T he original “Star Wars” film, in which a band of plucky rebels defeat a technological superpower, was a none-too-subtle inversion of the Vietnam war. The Marvel universe, originally a product of the cold-war era, has adapted well on screen to a post-9/11 world of surveillance and the conspiratorial mistrust of governments, large corporations and the power of technology. Inuncertain times, when governments and military might seem unable to keep people safe or stay honest, audiences take comfort in the idea of superheroes who ride to the rescue. Modern myths also have the power to unify people across generations, social groups and cultures, creating frameworks of shared references even as other forms of media consumption become ever more fragmented.Ultimately, however, these modern myths are so compelling because they tap primordial human urges—for refuge, redemption and harmony. In this respect they are like social-media platforms, which use technology to industrialise social interaction. Similarly, modern myth-making, reliant though it is on new tools and techniques, is really just pushing the same old buttons in stone-age brains. That is something that Walt Disney understood instinctively—and that the company he founded is now exploiting so proficiently.迪士尼星球大战,迪士尼和神话创造一个公司如何成为兜售故事的商业传奇从遥远的星际抵达你周边的电影院—《星球大战7：原力觉醒》这部星战系列的最新影片就在圣诞期间上映，不容错过。
MyCoin译比特币将取代黄金的存在大家等待着的央行4.15文件的靴子终于落地了,到今天为止主要交易平台陆续都收到了银行销户的通知,然而位于香港的比特币平台MYCOIN.HK目前并没收到相关通过,但是亦因如此导致用户量大增。
因此作为MYCOIN的小编最近也注意到网络上出现了一篇名为“比特币将取代黄金”的软文提供给大家参考下,作为缓解目前国内比特币的紧张局势之用。
比特币将取代黄金,但是仍然没有相应的文件出台,不管政策是怎么样的。
《黑天鹅》一书的作者纳西姆·尼古拉斯·塔勒布说过:“比特币必须经历被若干政府禁止、被政客攻击的过程,否则就不配成功”。
比特币会一直受到政府的阻止,政客的攻击,如果你拿不住手里面的币,不是有人坐庄,不是央行的禁止,是你自己的问题。
回到我的主题,比特币的价值。
比特币vs黄金,比特币将会胜出,比特币的总市值会超越黄金的总市值。
比特币相对于黄金有哪些优势呢?黄金作为稀有金属,总量恒定。
黄金主要的作用,工业上面的使用,首饰,财富的储存。
黄金在工业上的使用比重很小,黄金目前最大的应用是在首饰上约占总量的70%,首饰的作用其实也是源自于黄金的稀有和稳定性,首饰也是财富的一种象征。
黄金可以用来储存财富,以应对通货膨胀,而面对通货膨胀,我们又有了另外的选择来储存财富:比特币。
为什么比特币会优于黄金呢?先看一条央行规定:个人携带200克以上黄金进出境或需报税,也就是黄金的进出境是有比较严格的规定的,对应前几天的一个报道:携带6斤"土豪金"出境惨遭罚没,还被判刑(缓刑。
存储财富的第一条是流通性,其实在国内黄金的交易也是有限制的,目前合法的交易场所是银行和交易所。
比特币的流通性,到达全世界任意的位置只需要10分钟(平均时间,没有任何人能够阻止。
只需要极地的手续费0.0001比特币(0.3元,0.9.0版本手续费将下降到0.01mbtc(0.03元。
只要自己保管好自己的私钥,不管你是把私钥放在电脑,手机,u盘,甚至是纸上,或者你得记忆力比较好,自己把私钥给背下来,不管你到世界的那个角落,只要你只私钥,你就能完全使用自己的比特币。
Bitcoin has bounced back in China, helping to push the virtual currency back above $1,000 a unit, as exchanges devise workaround solutions to the regulatory crackdown last month.比特币在中国展开反弹，推动这种虚拟货币的单价重返1000美元上方。
针对监管机构上月出台的打击措施，各交易所拿出了变通办法。
When Chinese regulators banned financial institutions from doing business with Bitcoin exchanges last month, the move was thought by many to spell the end for the virtual currency in China. Would-be buyers were told they would no longer be able to transfer cash on to exchanges via digital payment platforms, in effect making it impossible tobuy Bitcoins.中国监管机构上月禁止金融机构经手比特币交易所的业务后，很多人以为此举标志着这种虚拟货币在中国的前途已被画上句号。
潜在买家被告知，他们将不再能够通过数字支付平台向交易所转移资金，这实际上使他们无法购买比特币。
“In the darkest hours we thought everything was going to come crashing down and the game was over,” said Bobby Lee, co-founder of BTC China, one of the country’s top exchanges.“在最黑暗的时刻，我们以为一切将要塌下来，游戏结束了，”中国最大的交易所之一“比特币中国”(BTC China)的联合创始人李启元(Bobby Lee)表示。
经济学家眼中的比特币：风险巨大具有革命性新浪科技讯北京时间4月15日下午消息，美国科技博客TechCrunch今天撰文，汇总了五位专业经济学家对比特币的看法：尽管这种虚拟货币存在巨大的风险，但从某种意义上看，它的确具备一定的革命性。
以下为文章概要：1、克里斯·罗伯特(Chris Robert)，哈佛大学公共政策与经济发展教授：如果聪明人都更信任一套在很大程度上由匿名电脑黑客建立和管理的货币系统，而不相信由真人组成的政府建立和管理的货币系统，那肯定就有问题了。
好在我们还没到那个程度。
如今，比特币主要还是媒体炒作，根源则是金融市场的持续动荡，以及对全球金融体系的不信任与日俱增。
然而，媒体炒作可能会导致长久的金融炒作。
在此过程中，越来越多的金融高手可能会与极客们一起，寻找有利可图的新泡沫。
与公司证券、期货，甚至金融衍生品相比，比特币的局限性更大，几乎没有什么基础价值。
泡沫可以不断膨胀，前提是只要需求增速快于供给——而且整个网络没有崩溃，新的漏洞没有摧毁一切，没人在乎匿名性的本质缺乏，那些丢失密钥甚至损失一小部分财富的人的抱怨声不要太大，挖掘技术的改进或是黑客技术不会突然对供给产生冲击，等等。
无论何时，利用泡沫来赚钱都很有风险，但我们的世界从来不缺敢于冒险的人。
所以，作为一项可能令人振奋的全新金融炒作渠道，比特币一段时间之内可能仍将存在下去。
2、罗伯特·麦克米兰(Robert McMilla)、美国联邦贸易委员会(FTC)前经济学家、斯坦福大学前经济学家，现任投资公司HNC Advisors A资产组合主管兼量化研究总监：比特币已死，比特币永生。
易于储存、难于盗窃、难于造假的交易媒介，肯定蕴含着巨大的价值，尤其是那些不会导致物种灭绝(例如白贝齿或象牙)或直接破坏环境(例如黄金)的模式。
不幸的是，了解保罗·克鲁格曼(Paul Krugman)“流动性陷阱”理论的人都知道，由于比特币的供给量有限而且已知，所以它注定无法成为货币的有效替代物。

（15）《经济学人》中英对照TEXT 1 Rebuilding the American dream chine 重建美国梦机器 Jan 19th xx | NEW YORK From The Economist print edition FOR America's colleges, January is a month of reckoning. Most applications for the next academic year beginning in the autumn have to be de by the end of De mber, so a university's popularity is put to an objective standard: how ny people want to attend. One of the more unlikely offi s to have been flooded with il is that of the City University of New York (CUNY), a public college that lacks, among other things, a famous sports team, bucolic campuses and raucous parties (it doesn't even have dorms), and, until re ntly, academic credibility. 对美国的大学而言，一月是一个清算的月份。
大多数要进入将于秋季开学的下一学年学习的申请必须在12月底前完成，因此一所大学的声望就有了客观依据：申请人的多少。
纽约城市大学，一所公立学院，与其他学校相比，它没有一支声名显赫的运动队，没有田园诗一般的校园，也没有喧嚣嘈杂的派对——甚至连宿舍都没有，而且，直到最近也没取得学术上的可信度，可就是这所大学的办公室塞满了学生们寄来的申请函，这简直有些令人难以置信。
不，比特币没有崩溃“比特币已经崩溃了。
”康内尔大学（Cornell）计算机科学家伊泰·伊亚尔（Ittay Eyal）和埃明·贡·赛尔（Emin Gun Sirer）声称。
在比特币对等支付的过程中，被称为矿工的计算机竞相处理着同一道数学难题，优胜者可以获得奖励。
通过对这一过程的规则进行分析后，研究人员得出以下结论：这些规则让少数矿工相互勾结，从而获得比他们应得份额多得多的奖励。
研究人员表明，从长期来看，这些互相勾结的矿工会掌控比特币网络，使得比特币网络丧失分散化的、对等支付的架构优势。
这种分析很巧妙，但它远无法证明非中心加密电子货币必然存在缺陷。
事实上，他们所说的攻击对比特币矿工来说仅仅是一个相对次要的问题，而且这个问题不会对比特币用户造成任何影响。
比特币交易结算流程跟买卖虚拟彩票很相似。
每个矿工出示一份近期交易的清单，这份清单被称为区块，然后再尝试着解决一个运算难题，区块会被用作这个运算难题的信息记录。
正确的解答（即运算结果）就像那张“中奖彩票”一样——很难找到，但它一旦被发现，却能轻易得到检验。
第一个找到正确答案的矿工将对其他的矿工公布结果，从而获得奖励。
短短几秒钟的时间，别的矿工就会对答案进行检验，证明这张“中奖彩票”是有效的，然后一切从头开始，矿工们产生新的区块，解决新一轮的运算难题。
在康奈尔大学（Cornell）研究人员的“攻击”之下，少数不遵守规则的有害矿工勾结在一块，希望能够藉此利用其他矿工抢先一步走在其他人前面。
他们的诡计是这样的：当一台有害矿工找到那张能使他获胜的“中奖彩票”时，他会和其他的有害矿工而非网络中剩下的的矿工分享这张“中奖彩票”。
这些有害的矿工放弃这一轮的问题，直接解决下一轮的问题。
与此同时，其他的矿工依然努力地为这个块区中已被有害矿工解开了的难题寻求解决方案。
这使得有害矿工在新一轮的比赛中不公平地领先了一步。
最终，一个遵守规则的诚实网络用户端节点找到了找到他的那张“中奖彩票”，并向网络中其他的矿工展示他的成果从而被检验。
一、什么是比特币？Bitcoin (sign: BTC) is a decentralized digital currency based on an open-source, peer-to-peer internet protocol. It was introduced by a pseudonymous developer named Satoshi Nakamoto in 2009.二、如何获取比特币？•The most common way to buy bitcoins are the Bitcoin Exchanges . •Accept bitcoins as payment for goods or services.•There are several services where you can trade them for traditional currency.•Find someone to trade cash for bitcoins in-person through a local directory.•Participate in a mining pool.三、与传统电子货币的差异1、Bitcoin is decentralized, the traditional electronic money has a service center.This makes bitcoin doesn't exist a separate holes are to be routed, stable system. But this makes the government'sregulatory face greater obstacles.中央银行：the bank of china2、Bitcoin stock is limited, can not casually increase issue, while traditional electronic currency can be unlimited rights issue.This characteristic makes bitcoin hold value is higher.3、Bitcoin code is open source, and the traditional electronic money are closed.Businesses, consumers, investors and service providers,to around the open source system to create a very richservices and financial system.4、Bitcoin because value is derived from the users increased gradually, the traditional electronic currency depend on fiat endorsement.This makes bitcoin value change more space. It means thatmore people use bitcoin, its value will increase more.四、比特币的优势：◆Bitcoins are sent easily through the Internet, without needing to trustany third party.◆Transactions are irreversible by design they are also cost very little,especially compared to other payment networks.◆The supply of bitcoins is regulated by software and the agreement ofusers of the system and cannot be manipulated by any government, bank, organization or individual.五、比特币的不良影响：1、The securityBecause bitcoin produced in the Internet, it is normal for it to meet some network security threat.2、The money launderingAt present, there are some illegal organization use bitcoin to do with laundering dirty money, like drug dealers.3、The legalityUp till now, there is no law to define bitcoin or to restrict it. It means that bitcoin was not recognized in the real world.4、The support of government.总结：In my opinion, Existence in possible，bitcoin would make new wonder only when it can be accepted by the public。

日本的在线交易所Mt Gox长期以来一直是比特币行业的佼佼者，而如今，这一平台4.9亿客户的比特币被盗，于是，3月11日Mt Gox又在向美国申请破产保护。

不断增加的证据表明《新闻周刊》的报道是错的，多利安-蒲伦蒂斯-中本聪(Dorian Prentice Satoshi Nakamoto)和比特币之父中本聪并不是同一个人。
更重要的是，如果比特币没有作为一种完全成熟的货币，而是作为金融创新的平台，那么达到比特币的全盛时代依然任重而道远。
如同互联网是数字化服务的基石一样，比特币背后的科技可以引领一场革命，而这场革命可以改变买方和卖方的交易方式。
各路极客们都异常兴奋，其中不乏渐多大批风险资本家，一旦一个新平台出现，这些人就会对其了如指掌。
3.To understand the enthusiasm in this modern currency, it helps to think about a very old one.

直到20世纪初，在太平洋一个名为雅浦的小岛上，人们用大石圆盘（如图）作为货币，用于大笔开销，比如女儿的嫁妆。
由于这种石头非常重，人们在花费的时候很少移动它，而是通过改变所有者来实现买卖。
每一笔交易都会变成所有权口述历史的一部分，因此，岛民们可以清楚地知道每块石头的所有者，从而不会产生同一块石头当两次货币来用的错误。
