比特币有什么价值？ * S. u! T0 m. y8 @" b6 ^
4 f4 c" H/ M- b. ], ]9 l* u7 S
# F7 {' _0 p$ K, @4 [+ ~; G 比特币具有货币的数学特性（持久性，可携带性，可互换性，稀缺性，可分割性和易识别性），但实现这些依赖的并不是物理特性（比如黄金和白银）或中央权力机构的信任（比如法定货币）。 5 I4 M- ]# F" j$ V5 ?" i
简而言之，比特币是由数学支持的。一种货币形式要具有价值所需要的就是信任和使用。有了这些特性，对比特币而言，这可以从它日益增长的用户，商家和初创企业基数上得到体现。同所有货币一样，比特币的价值直接来自于愿意接受它作为支付方式的人们，这也是唯一的来源。 - d* Q9 u. O* a* b2 ~7 E/ G- _
没有银行或ZF参与该过程，因此比特币是执行某些活动（例如转账）的绝佳方式，下面介绍了其中一些理由：2 U& A' M7 Q* p( e3 h2 c- I
5 m Q8 M! f! l" d; S( _一，人对人直接转账，没有中介机构参与/ ]* L& W" S- m2 f4 {
# O. Y$ S: W% I, }& o# B* q+ d1 |
通常来说，转账给不在你附近的人需要使用银行或其他汇款服务用于加快转帐。er使用比特币发送资金相当于从自己的钱包里拿现金给某个人。
9 L# ~8 X# ^6 n# W' D( `: U3 z/ z4 u
二，费用近似于零
8 Q2 n% m6 j# n* q7 w! C9 y
( ~' d2 d; N& M9 Z6 |: y 比特币没有中间商。这意味着为收发比特币资金而支付的费用基本上近似于零，或非常低。这是比特币的一个重要优势，对于小额付款来说尤其如此。银行转账和信用卡付款需支付大笔费用，令发送小额资金变得十分困难。比特币的结构巧妙而有利，结算费接近于零对比特币而言是轻而易举的事情！* ^/ U9 R. Y* U( ~7 Z/ j7 A7 y6 C
; s, n9 ]! ^) m, T9 K* h- K+ [三，没有任何第三方监督或设定限制
4 o4 w% u% A8 J9 ?( [1 b# T* Z
8 Y% l$ G! K) N/ E& A4 _ 比特币不要求银行或第三方结算，因此过程更加快速，资金能够自由流动。比特币是全球性的，国与国之间没有货币单位差异。全世界目前已经有很多店铺和网站接受比特币。+ \0 R& s g+ `: v" L( U7 {4 z; [
6 E. T+ f1 m6 S c2 _
此外，比特币的总量也是有限的。比特币数量被设计为上限2100万个，以避免通货膨胀问题。全世界仅有2100万枚，它的产出经过精心设计，由代码来控制产出。一枚比特币最多可以被细分到小数点后8位，而且每4年，比特币的挖矿产出就减半一次，并将在2140年发行总量达到2100万枚时停止产出新比特币。4 l7 A, R5 b9 a! e2 ]- W
9 C6 e8 w9 E- x, `1 Y, G 所以它有一定的稀缺性，不会像纸币一样可能因为滥发而导致贬值，又很容易被分割，获得它的获得过程跟挖黄金也很像，因此它被人们誉为“数字黄金”。
