【明報專訊】一年升值78倍的網絡虛擬貨幣Bitcoin(比特幣),近日遭內地打壓。繼
人民銀行在周四(12月5日)表明,Bitcoin非真正貨幣,更禁止金融機構使用後,內地
科網巨頭百度昨晨亦發聲明指出,拒絕收取Bitcoin。結果,其價格在兩日內跌逾30%,

Bitcoin作为网上转钱的工具,具有快速,费用低,不会被追踪的优点。
我不知道为什么现在网上扑克室没有普遍采用这个方式存取钱。但是将来是有可能的。
现在有少部分网上扑克室用这种方式存取钱。从提交提钱申请,到钱提到自己的
Bitcoin户头,大概在两小时之内。而从自己的Bitcoin户头,转钱到自己的银行,需要
2-4天。
用Bitcoin存钱取钱,需要开两个Bitcoin有关户头(都是免费)。
第一个是www.circle.com。这个户头的功能,是把钱从自己的银行,转出来并换成
Bitcoin,或是相反。(同样功能的网站,还有www.coinbase.com。但是coinbase把$转
换成Bitcoin要收取1%手续费)
如果美国法律不禁止网上赌博,就可以直接用circle.com转bitcoin到网上扑克室。但
是现在circle.com禁止和网上赌博发生关系。所以需要开另一个Bitcoin“钱包”。这

来自主题: Stock版 - BitCoin 跌到70了
优点
1、无需信托中间人,能够方便地进行互联网上的汇款。
[1]第三方不能够控制或者阻止您的交易。
2、 Bitcoin 交易几乎免费,而信用卡的网上在线支付系统通常收取 1-5% 的交易费用
,加上其他各种费用高达数百美元。
3、避免了中央储备银行的不良政策和不稳定性所造成的安全隐患。Bitcoin 系统的有
限货币通胀是均匀分布(由CPU决定)于整个网络,而不是由银行垄断。
缺点
1、Bitcoin 可能被用来从事非法活动,包括销售盗版和伪劣商品,偷盗信用卡甚至儿
童色情,并且还有个灰色领域,Bitcoin 可以让美国的成年人在英国合法的博彩网站下
注而不用担心交易受到限制。
2、易被封杀。目前 Paypal 和信用卡公司都宣布销售Bitcoin 非法。CoinPal 已经冻
结了Bitcoin 的交易。也有分析人士认为政府在未来12-18个月内会封杀 Bitcoin。
3、按照设计,Bitcoin的世界很可能将有持续不断的通货紧缩,原因是货币供应在
Bitcoin的世界里将会渐进到一个指定的水平,而一旦使用Bitcoin的人越来越多,进行

bitcoin总量固定,但是人类GDP一直在增长,也就是说财富一直在增长
这造成bitcoin币值必须随着GDP增长而增长,
由于这个原因,N年前一块钱买下的一个bitcoin,N年后价值就会增长成为(1+N)^a,
所以,先拥有bitcoin的人,可以自动掠夺后拥有bitcoin的人的财富,这种掠夺,
根本不用枪炮,只要你买了bitcoin,就自动给已经拥有bitcoin的人自己的财富了。
所以,bitcoin必须禁止,这种货币,是违反基本金融规则的

来自主题: Hardware版 - 分析:BitCoin的软肋
BitCoin的确有软肋。
不过这些软肋,别看回复中叽叽喳喳,但其中没有几个说到点子上
BitCoin的软肋:
1,有其它crypto currency可替代。
如果bitcoin的币值过高(或者过低),人们,尤其是新来的,会选择其它货币
另外,其它crypto currency可能在技术上有更先进之处,比如发送更快,更匿名等。
只要可替代货币得到一定数量人们的认可,就OK。
2,价格涨得过快,失去货币的值能。
货币的一个特性就是稳定,既不能过涨,也不能过跌。
按照目前bitcoin这个涨法,前一天商议好的价格,第二天就能涨30%,
这对于买家是一个沉重的负担。
这样一来,虽然卖家希望收bitcoin,但买家不愿意付。一个巴掌拍不响,交易无法进行
所以,要bitcoin回归“货币”本职,就必须保证有比较低的volatility
目前这么涨法,volatility过高,市场的参与者只能投机
3. 价格越高,越不安全。
想想吧 ,如果你有100个bitcoin放在交易所,如果每个值2000美元,
你怎么才保证这些coin都是安全的?你能相信交易所吗?你能相信天下无hacker吗

乱说,你怎么不说佛罗里达的一个墨哥当初用上万bitcoin买了个pizza呢? bitcoin开
始时大家都不当回事,有过的几乎全卖了。能留到现在的没有几个。
取得bitcoin的方式事实上有两个:
一个是和股票一样从市场上买入;
另外一个是挖矿,就是根据运算方法,依据挖矿人矿工多少也就是挖矿机输出的算法比
值,构建矿区block,在里面寻找待发行的新bitcoin。当然,现在发行量是倍数级别减
少的,也就是矿会越挖越少。
但是,中国某个有5800台矿机的某家矿主,年度输出的算法总合大约占全球算法总数
的6%, 一年能挖上千个bitcoin呢。

1,有其它crypto currency可替代。
这是有可能的,但是在可预见的将来还没有看到有替代品。
2,价格涨得过快,失去货币的值能。
涨这么快是暂时的,因为谁也不了解bitcoin和现实货币的兑换率到底应该是多少
但是bitcoin的机制就是确保了bitcoin本身不会过快地贬值,所以当兑换率稳定
以后,bitcoin是一个很稳定的货币。
3. 价格越高,越不安全。
确实已经发生了多起hacker偷钱的事情,而且能确认的只有这些钱确实不见了,
是谁干的,这些钱现在在谁手里都不知道。每偷一个,比特币就跌一次。
这个是比特币的一个很大的弱点,信用卡被盗用了可以到信用卡公司去退钱,

首先,看不懂中本聪原来论文的就别发言了。
中本聪的文章全面enginneering了戴伟等先驱的想法。达到了最后这个
看上去很简练,但实际上规避了大量风险和漏洞的成品 。这不是偶然或者运气。
他的每一步设计都是有很深的工程技术上的tradeoff在内的。
很多东西如果不追溯密码朋克那一卦人之前反复讨论过的各种陷阱,
你压根看不懂。
第二,Bitpay每天 7M交易量,这足够说明了需求和这个设计的强壮。
这还只是次要的需求。
第三,Bitcoin值多少现美金,根本无关紧要。你琢磨下中国有多少贪官
需要把人民币洗到美国吧。考虑进出的延迟,比特币洗钱的时间假设为T.
如果T时间内比特币的波动造成的潜在损失不大,那就是及其优良的洗钱手段。
而且这里有个正循环。洗钱的人越多,越稳定的利于洗钱。
一边有coinbase,另一边有... 阅读全帖

你还是看看纽约时报怎么说的吧:
One striking thing about the map: Bitcoin is increasingly a Chinese craze.
Even at the height of the American and European trading days, when it’s 3 a
.m. in China, Chinese transactions far outstrip activity in euros. The
United States dollar transactions are still more popular than Chinese at
that time, with about twice as many transactions. China was barely involved
in bitcoin a year ago, however. The Chinese presence can also strengthen
when it is daytime in China and night in... 阅读全帖

That doesn't mean it's a legal currency. Trades conducted with bitcoin in
legal definition is probably close to barter trades. Barter trades are very
hard to tax because the value of trade is hard to define. Now that bitcoin
has an exchange rate with real money, its value is determinable, and thus
taxable. But tax will still be paid in domestic currency, not bitcoin.

美元事实上让全世界尤其是中国成为美国人的奴隶,全世界范围插管吸血,窃取劳动人
民的劳动果实来养美国黑墨穆(公平的说,三是不包含在内的)。人民币挑战美元对中
国来说是路线没错,但危险系数高(欧洲和老毛子的下场我们也看见了),而且即使成
功也逃不过历史的循环。即使成功了,几十几百年后也难免循环走。折腾来去,都是短
期利益。总归还是没有促进人类整体进步,只不过是天平一会倾斜东方,一会倾斜西方
,如此往复,日久不息罢了。
我提出个想法,让bitcoin成为世界货币,可以保持公平,谁也没义务给别人当奴隶。
每个人都只能给自己当奴隶。
bitcoin本质是个货币实验,他的理论基础可以确保其天生的公平性。分布式系统,谁
也没有控制权,任谁也别想插管吸血。等于是回到以物易物的基本模式结构,以物易物
是商贸的本质,货币回到其原本的功能:仅仅为了携带方便而已。
bitcoin和美元 人民币的根本区别在于其本质不是政府或任何金融机构发行的货币,他
的decentralized本性是其革命性所在。他的出生源于其创造者对于政府或任何机构的
不信任

按说,他们收了BITCOIN,但是他们的顾客或供货商需要美金,它就得把BITCOIN卖出去
。BITCOIN对美元比率稳定的话不会成问题,但是这种每天每小时都波动可咋整?难不
成他们知道这东西肯定长,今天早上买的,晚上肯定能卖高?或者屯着?他们有那么多
现金储备马?谁告诉他们100%只涨不跌?零售商TIGERDIRECT屯货可以理解,但是屯现
金好像就走火入魔了,不理解,困惑求解。

I just read a little about it. It's definitely a brilliant invention and
worth some discussion.
I don't think it will eventually prevail as a currency since:
1) Security is always an issue. Even though the algorithm and transaction
sequence are kept in every node and cross-checked at any moment, as long as
they can be updated, it's certainly possible and eventually inevitable that
a malicious version will take over the entire network.
2) I don't see the proof that this "bitcoin" system is unique... 阅读全帖

No, you don't get it. This is fundamentally different.
We are talking about a currency that is expected to mimic gold. Gold is a
store of value because it's not reproducible. Not only can't you produce
gold out of air, the number of similar alternatives are also limited (silver
, platinum, etc...), and they settle at a relatively stable exchange rate
with gold.
When (if) the bitcoin economy grows and its value appreciates, you will find
the early users commands an amount of bitcoin currency vast... 阅读全帖
