火币网USDT的作用如下：
The role of the Signal Network USDT is as follows:
1、规避整体下跌风险
1. Avoiding the risk of overall decline
币币交易中，常见3种情况，以LTC/BTC交易为例：
In currency transactions, three cases are common, for example, LTC/BTC transactions:
用BTC买入LTC后，BTC和LTC都在涨，你享受两份收益;
After buying LTC with BTC, BTC and LTC are on the rise and you enjoy two benefits;
用BTC买入LTC后，BTC和LTC一个涨一个跌，你的收益取决于两个币种的涨跌幅，那个更大。只有任何一个的涨幅大于另一个的跌幅，就赚。反正，就亏。涨跌幅相等，则不赚不赔;
When BTC buys LTC, BTC and LTC go up and down one by one, depending on the increase and drop in two currencies, which is larger. Only one increase is greater than the other, and the profit is greater. On the contrary, the loss is the loss. The increase and fall is equal, and the gain is no loss.
用BTC买入LTC后，极端行情，两个币种都在跌，你需要承受两份亏损。这往往是最让人糟心的。
When you buy LTC in BTC, you fall in both currencies, and you have to suffer two losses. That's often the worst.
但是有了 USDT，是当币价下跌时，可以立刻把币换成 USDT，从而保证你的资产不缩水。
But with the USDT, when the currency falls, it can be replaced with the USDT immediately, thus ensuring that your assets do not shrink.
2、反向操作 数字货币提现
2. Reverse operations
充值很简单，USDT公司称投资者可以通过SWIFT电汇美元至Tether公司的银行帐户，或通过Bitfinex交易所换取USDT。
The charging value was simple, and USDT stated that investors could wire the United States dollar through SWIFT to Tether's bank account or exchange USDT through the Bitfinex exchange.
如果你获利颇丰，想要提现，可以先把手中的币兑换为USDT，然后通过 Tether 公司或其它平台，兑换为美元。这里你可以发现，如果你完成USDT公司的认证，在其它不需要认证的币币交易平台就可以直接进行交易了，不需要再次认证其它平台。
If you are profitable and want to cash it, you can exchange the currency in your hand to USDT and then to the dollar through Tether or other platforms. Here you can see that if you complete the USDT certification, you can deal directly with other currency trading platforms that do not require certification, and no other platforms need to be certified again.
