“比特币和造假币无异。”投资者L说,私人弄出来的玩意可以和国家强制力发行的货币对等,这个游戏规则注定了比特币要破产。“国家以生产力、黄金储备等等硬实力支撑发行货币,比特币呢?就好像一个村子的人自己用纸画钱,然后想跑来跟全世界的人买东西。造假币的还要自己买纸,买油墨,买复印机,这个东西什么都不需要。”4 \2 G% z w# r
另一名用户F迅速反击:“先学点基础的金融知识吧,矿工购买电脑、显卡,交付电费的钱不是其劳动所得赚取的吗,然后还需要经常维护更换耗损来维持挖矿,本质和挖任何一个现实存在的矿没有任何区别。”' L" U$ d! U# [, H) z
“现实中挖出来的矿物是有很多用途的,比特币呢? ”第三名用户H反唇相讥。3 L; A6 J2 A( T
“那纸币其实也只是一张纸,跟假钞又有什么区别? ”F问。 5 N# G1 y, f$ ?$ F( W5 R2 x9 w: XL继续质疑:“纸币是有国家信用担保且强制流通的,比特币出了小圈子谁认呢?你说纸币是假钞,那送给我好了。 ”( I9 ]# n8 r0 M/ f0 i- N
“我早就把‘假钞’换成购买力更强的比特币了,任何一个接触比特币的人都会发现传统体系的巨大局限性。”F回答他。# j! c2 {9 g0 d/ h! a/ R
看到上述对话后,刘二迅速向记者做出了他自己的判断:F是媒子。“媒子就是不断对外界鼓吹比特币好处的人,他们自有一套逻辑体系。不排除媒子中有一些真心崇拜比特币的极客,但大多数都是想找愣头青接盘的炒作庄家。”6 u* y. c/ J2 F% z/ Q7 y
事实上,经历了不久前的比特币暴跌后,质疑者正在持续增多。“别被一些炒客所蒙蔽。他们正在让后来者为他们虚构的价值观埋单。就像前些年炒君子兰,泡沫自然破灭后,接最后一棒的人倾家荡产。当然,君子兰本身还有些实用价值,而比特币一点没有用。”用户好奇20130318在百度贴吧中炮轰。( e/ @3 q2 q+ G! L
“有人说比特币是通过开着计算机浪费着电费创造出来的,不错,正是因为有这样一个错误的逻辑思维才能支撑着这样一个圈套。就好像您在家做了1000个俯卧撑,累得满头大汗,最后把汗都攒了起来,然后找个人说我这汗是用体力换的,所以你就应该买我的汗。可笑吗?”上述质疑者说。 ) }' }! t1 f8 s9 X; i+ Y$ I: C 0 U; p2 s* q" h3 \# h8 P0 {1 f挑战国家金融体系 0 _1 s0 j, v, S2 H ( y n' d) j& L- P# q在投机者的炒作下,比特币或许已稍许背离了中本聪的初衷。但直到目前,仍没有哪一国ZF出面对这种虚拟货币叫停。 6 @9 z; n$ }9 }; \' p尽管如此,来自民间的质疑声一直未曾休止,在利益追逐下的不和谐之音也不绝于耳。记者查阅维基百科发现,2011年6月,赛门铁克警告称,部分狂热的“矿工”通过控制他人电脑的“抓肉鸡”方式来秘密挖掘比特币。这会消耗电脑计算周期,消耗更多的电量以及使得计算机温度升高。不到三个月内,发现了专门感染MacOSX操作系统的比特币“挖掘”木马。 5 ~7 U' c$ b3 @: H3 C8 u# c- s记者同时在《比特币沉浮录》一文中看到,美国参议员查尔斯 舒默曾专门举行记者招待会,呼吁毒品管理局和司法部关闭“丝绸之路”,他称其为“我们所见过最明目张胆的网上贩毒行为”,并形容比特币是“一种网上洗钱形式”。) Q: x, }, }2 D
“比特币已经疯了,我们正在见证一个巨型泡沫的诞生。比特币泡沫将是唯一一个具有全球性质、全世界的人一起参与的泡沫,未来将涨到让所有人震惊的地步,等到它崩盘,将会套死一大群人。”段宏斌不久前说。- j7 p+ b. I8 h4 a/ m* ]$ u+ Q
IT律师赵占领分析称,比特币投资目前主要有两大风险。第一来自监管层面,随着比特币的功能范围扩展到支付手段、涉及金额逐步增加、影响范围逐渐扩大,最终必将引起各国ZF监管。没有哪个国家会允许这种不由中央银行发行、不受监管、却又冲击法定货币的虚拟货币的存在,直接涉及到一国的金融主权和金融秩序。, i& P+ l0 u7 m! p/ b# e
“而且,这种比特币不同于之前已有的网络运营商发行的虚拟货币。网络运营商发行的虚拟货币总是中心化的,对于ZF而言是可控的,目前ZGZF的主要控制思路是两点:第一,使用范围仅仅限于发行商自己提供的虚拟产品或者服务;第二,不能反向回兑,以免虚拟货币具有流通的职能。”赵占领说。7 ^: S. Y( `% ~6 y @$ z
第二重风险来自安全层面。赵占领告诉记者,比特币虽然由于技术和算法设置可以避免被伪造、避免通货膨胀,但是却存在重大的安全隐患,一旦被黑客攻击,仍可能会给持有者造成损失,甚至给比特币本身带来信用危机。 ! ~2 H* `/ L/ I9 o9 f# }3 z- b* H; E0 j$ {) b8 x0 q. f6 w

(MoneyWatch) Until last week, plenty of news stories were talking up the digital currency Bitcoin, created by anonymous engineers. It has been touted as the brave new world of Internet money, a pure "mathematical" medium of exchange with a barely changing supply, untouched by the corrupt hands of central bankers and the inevitable inflation they cause. You could use Bitcoins to buy lunch. Or a house. % L3 v9 d+ S5 e 0 j9 p" d7 [5 \ a0 zWell, if you did want to buy a house using Bitcoins as your medium of exchange, it would have been best to arrange for a closing no later than Wednesday morning. Because later that day, when the value of one Bitcoin reached an all-time high of $266 to a U.S. dollar, the digital money took a swan-dive. By late Wednesday, if you were still committed to the transaction, your house would have cost you twice as much -- and even more if you had waited until the following day, because Bitcoins just kept losing value. , M, G! q6 v* S( B, \ $ D- k' @+ `1 p1 jIt's not exactly a case study in how to conduct a real estate transaction. Or even the purchase of a falafel sandwich. Bitcoin's sharp rise and fall, coming after stories about unwitting people pouring their life savings into the fledgling currency, has called its future prospects into question. And amid all the hype about a new type of alternative money, the Bitcoin story raises questions about what a currency is and why people do or don't trust it.# p4 j; i! x/ H+ J1 B( ?( j6 g

"There has been a lot of confusion about what money is," said Steve Hanke, a professor of applied economics at The Johns Hopkins University in Baltimore who has advised many countries on currency questions. Bitcoin "is a very speculative asset. One of the functions of money is a unit of account for future payments, like a mortgage payment, so if you've got a lot of instability it's a big problem." # C; k$ j1 ~4 |6 h0 b& J# i$ W0 g 2 S0 i8 L( D0 V1 m" QInstability is putting it mildly. Owners of Bitcoins had already seen booms and crashes, but the rise last week was the big daddy of the new money's young life. Within 26 days, the value of one Bitcoin soared from a little over $40 to over $266, before turning tail and crashing to as low as $40 the next day. The move up was said to be tied to hot money getting out of Cyprus after the island nation last month clamped down on banks and confiscated deposits. " k0 q. s4 Y% b7 C$ c% b2 _) G. x7 h, D3 q* c

The price of a Bitcoin had been rising more or less steadily in recent months, but the Matterhorn of price surges came as economic troubles in Cyprus reached a boiling point in mid-March, when regulators put out the word that they would be confiscating a percentage of people's bank accounts.& L9 p; ~4 P9 c. h# C; _2 ~

"There was a very high correlation between the trouble in Cyprus and the Bitcoin's surge," Hanke said. "The crisis starts developing, then you get a few stories arguing that if capital controls are put in place in Cyprus, people would move into Bitcoin -- that it would be a natural escape route."1 A6 k. l5 A' Z& Z
7 \- B' H( T4 t1 P7 `7 e4 HThose predictions, Hanke noted, were not so accurate. "No one bothered to look at the where the money was coming from," he said. "It was all money from the United States and none from Cyprus. The expectation was that Bitcoin would be used, so people started buying capacity. And if the supply is fixed in stone, then it's a perfect storm for a huge price rise."8 ^$ Q; W+ O! Y% L& E: V/ Q

For devotees of Bitcoin, its finite supply is a key draw. The number of Bitcoins is growing slowly through so-called "mining," in which geeks with powerful computers can earn extra coins by answering challenging mathematical questions about Bitcoin's supply and demand. The supply of Bitcoin will stop growing entirely in 2040. * k; N1 A$ B4 g S: t, Y7 T, t ( x: b5 _+ u( p5 I. h/ [But that feature, as Hanke notes, becomes a liability when demand surges and sends the price of Bitcoin precipitously higher. Even without such a spike, a currency that grows ever more valuable will not be suitable for a medium of exchange. People then hoard the currency, rather than spend it, as they anticipate they will be able to buy more with their money in the future. ; ]( X( `' `6 h2 Y3 W* w/ G

/ y4 T0 C& @9 A( |5 N* YDislike of the Federal Reserve's easy monetary policy has prompted investors and analysts in both camps to predict rampant inflation. While so far that hasn't materialized, those beliefs have helped fuel a dramatic rise in the price of gold, a traditional hedge against inflation. Perhaps coincidentally, gold prices had been falling for months, but suffered their own monumental plunge on Monday. Sites such as Zerohedge quickly claimed that the government had sabotaged the price of gold just as they had the price of Bitcoin., y. V1 W8 [+ g
( k0 H( d! D$ b D
"A core group of Bitcoin users are extreme libertarians who are similar to goldbugs," said Reuben Grinberg, a lawyer at Davis Polk & Wardwell who began writing about the legal and economic underpinnings of Bitcoin while he was in law school."They don't like government regulation and prefer anonymity, privacy and autonomy. They want to abolish the Federal Reserve and think central banks in general hurt the economy, and they also distrust the established financial system, including well-known financial intermediaries such as banks. For them, Bitcoin is a perfect embodiment of their ideals: no central government control over its supply and apparent anonymity, privacy and autonomy. Owning Bitcoins is a way of life for some of them."+ }0 d# B( |) F

Take for example, the libertarian Mercatus institute at George Mason University. Jerry Brito, a senior research fellow and head of the technology program there, said in a recent video on the center's site that "people who like liberty are going to be excited about" Bitcoin. One of the concept's main benefits, he said, "is this idea that the central authority doesn't control the money supply, so they can't just print more money, so your money is going to be more stable and your money is going to retain its value." 5 f& [2 {. r# p6 v& z- j0 v - O- a* v& d L8 hIn an interview the day Bitcoin's price was collapsing, Brito backed off from the notion that it can serve as a stable store of value, but argued that there is a future for either Bitcoin or perhaps some other virtual currency that comes along to replace it. "It's revolutionary for lots of reasons," he said in an interview. "Among them is its anonymity, the difficulty of governments to control it and the absence of a central banker." $ ]& ?9 h8 j- w$ K M3 T7 u6 Z) }- l; y
Brito and others cite the case of Wikileaks, which saw banks and other financial institutions launch a financial blockade to stop supporters from sending payments to the hacker organization.0 X' c# ^2 ]7 m7 y( \
8 l! B) D" E- TBut one man's liberty is another man's virtual corner drug deal, a fact which, like Bitcoin's price volatility, raises questions about its future. Experts agree that a large chunk of transactions using Bitcoin is illicit, involving the purchase of either drugs such as marijuana or psilocybin ordered over the Internet, and gambling. One possible response could come from governments that might seek to regulate the newfangled unit out of existence.( ^* `( X9 J. ^; s; g

6 _7 x b$ F3 u5 u0 p$ NGrinberg, who attributes the dramatic rise and fall of Bitcoin's price to media attention that drew in a lot of unfortunate speculators, said he hopes its price stabilizes and that the new currency becomes entrenched and used for legal purposes. "There is inherent value, but there are a lot of hiccups and there is a lot of risk," he said. "I would never encourage an average investor to get into it. But I'm cautiously optimistic.", d5 o" g4 i$ I3 w }
% W) d: G1 l- n# Q7 Y6 j) r: u! xHanke, who has advised governments from Argentina to Estonia on currency matters, has his doubts. "This industry is in its infancy with very few barriers to entry," he said. "The costs are low to produce something like a Bitcoin, and once that comes into the picture then you could get an alternative supply, and then the finite resource isn't so finite. But if it appears to be a viable challenger to state money, the governments will try to eliminate the challenger. It's very profitable for states to print money." ; h+ ^; X* T }% } 4 H4 P5 A9 i+ H; B"The other alternative," Hanke added, "is it goes no place and becomes an interesting footnote in money and banking books." 5 [* X+ D4 A1 |1 f 8 `, [% Q$ H3 b9 y4 O- Shttp://www.cbsnews.com/8301-5051 ... in-we-cannot-trust/作者: admin 时间: 2013-4-26 12:42
