比特币有什么价值？ 6 v1 R+ o, J- J, n7 A: P2 L8 r
8 L9 V/ J1 C. y1 F4 f
. l7 M( h* J% L4 }* C3 J 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）。 # k, [$ W. M. j L2 v5 p$ @
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。
& f% I: b# i" |& D: V7 O1 y9 j 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：7 F& y0 U6 d4 s" k
9 n: Z) \4 G: x一，人对人直接转账，没有中介机构参与1 f& s j& N4 ^% B) u9 O
' b/ g& [- V( y7 P% Z9 L 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。+ O3 J/ L& Y* T, n
5 C; d* W( p$ w0 E* r$ l8 H二，费用近似于零$ u3 D8 D: {: e! d
- R( ? p# C+ a1 q$ l& H v3 p: } 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！+ m; \* I( U% J: L" w
; k8 w8 ^: f' e% w% o
三，没有任何第三方监督或设定限制) Q) z! \+ g2 i: d; a% q( i) N
2 o" P( y# u5 b& F6 a" Y
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。/ A5 V( E# R: d! p' s8 @ G
+ f& c# y8 L8 f 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 p. x6 J }# B4 D* k( k. s) \1 n8 X7 Z6 U' r6 @
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”。
