 比特币是个啥?


  洋名Bitcoin,国际代码BTC,你可以把比特币理解成网络中的‘虚拟黄金’。四年前,有个神奇的哥们儿(据说是个叫中本聪的日本人)研究出了一种计算机算法用来模拟现实中的‘掘金’过程。 如果你完成了这个算法所设定的任务,就能获得25枚比特币(就跟19世纪淘金热中,‘你挖出了金子,这金子就归你了’,有点类似)。这种算法最终只会创造2100万枚比特币(这就好比‘地球上黄金的数量是有限的’)。因为比特币的‘供给’是有限的(人民银行也没法像印人民币一样复制出更多的比特币),它幸而免受‘通胀’影响;换句话说,随着时间推移,咱手里拿的普通货币只会愈发不值钱,而比特币的价值却会只升不降。

  比特币vs. 物理现金


  1)共同点:

  · 不需要第三方的核实,就能在甲乙两方之间安全地流通。

  · 有防伪措施,造假不容易。

  · 内在价值是零;它的价值只取决于人们愿意拿它去交换什么。

  · 如果被偷就找不回来了,别人拿到了也可以随便花。

  2)比特币的专属优点:

  ·它是数字(虚拟)的,而不是物理的,可以通过互联网进行流通。

  ·它的‘供给’有限,不能被人为再造(财政政策或者央行印钱那招都不好使)

  3)比特币的专属缺点:

  ·没人有义务一定接受这种支付方式;你不能用它付债,也不能拿它交税。

  ·不像其他货币一样具有‘区域性垄断’(比如中国有了人民币,就不会出现农民币);比特币的竞争者(Litecoin,Devcoin…甚至航空里程)可以源源不断地跑出来跟它争宠。

  如何获取比特币?(两种方式)

  · 通过‘挖矿’(完成那个人工算法所规定的任务),这只会越来越难,因为‘待挖’的比特币越来越少。

  · 通过类似Mt.Gox 这种线上交易平台,用普通货币(美金、欧元、人民币…)来兑换。目前,一枚比特币值130美金(这个汇率可以在Preev.com随时查询)。

  为毛投资比特币?

  它是互联网黄金,数量稀缺,价值会只升不降。在一些金融濒临瘫痪的经济体(如塞浦路斯、希腊etc.), 人们对传统货币(如欧元、美金)已经失去信心。如果一个国家遭遇像希腊这样严重的国债危机,政府其实可以分分钟掌控你存在银行里的所有财产;也可以大肆印钱,让你手里的票子一文不值。当然,如果你的财富形式是比特币,Big Brother就没招儿了;这时候,你硬盘里的比特币就像你的银行,他们没办法进入你的地盘。这就好比人们将大把钞票塞到床垫底下,只不过比特币比那个划算多了,也方便多了。
