USDT作为稳定币能够稳定的原因 ) F/ ~. @/ V" {) W9 I! d) F) N8 K
+ E2 F) y i U. h
) h3 p6 A9 D# }8 w) H2 H: U 作为法币与加密货币的桥梁，USDT一直有两个大类的市场，其一是各种加密货币兑换USDT的市场，包括中心化交易所和Defi上的市场；其二则是USDT1:1兑换美元的市场，这个市场主要由USDT官方兑换、大宗场外交易商和一些合规交易所的USDT/USD交易对所组成。
' `, C: U/ w3 I1 ~5 z USDT兑换各种加密货币的价格由市场决定，Tether公司无法干预。但USDT兑换美元的价格，Tether则必须确保为1:1，否则USDT就无法发挥稳定币的作用。所以，Tether官方承诺USDT和USD1:1的兑换，对于一些大宗的美元场外交易商，同样依赖于Tether的官方兑换。 : |- f+ [9 e8 R8 Q
但是查阅Tether官网可以得知，官方兑换美元的门槛为至少10万美金，手续费则为1000美金或是兑换金额*0.001之间的更高者，由此可见，对于散户来说，去Tether官方并非最优选择。 8 }$ J* N- T. Q0 `* o
而在Tether的【用户条款】中，则有这么一段话： 0 _+ x9 Z- \. n
“Tether保留在Tether的储备资产发生流动性问题或是产生损失时，延迟兑换给用户美元的的权利，同时Tether保留兑换给用户证券或是其他Tether持有的储备资产的权利。”
4 N: k( e1 X! O! x$ C9 a 也就是说，当用户拿着USDT去找Tether兑换美元的时候，Tether有可能没钱可兑，也可能只能给用户一些它所持有的等价物。
! e$ p L `6 j2 ^6 W5 F, P 众所周知，Tether并不持有相当于其usdt发行总量的美元，而是持有同等数量的资产，这些资产由哪些东西构成，目前Tether尚未向外界公布。 ) z2 h+ e" e, {' P' s- E
因而，Tether保持USDT稳定币汇率的主要做法，则是通过在USDT/USD交易对做市来保持1:1的汇率。目前有USDT/USD的交易所主要有三个，分别是Bitfinex（24小时交易量7000多万美元），Kraken（24小时交易量4000多万美元）和FTX（3000多万美元），三者24小时交易量总和为1.5亿美元，对于拥有400多亿资产的Tether来说，通过做市维持汇率轻而易举。 |
