在比特币中，1 sat 是多少美元？

普通人绝对想不到，比特币能在2024年达到这个价值，早知道的话，我当初就是破釜沉舟也得买一个啊。

No ordinary man could have expected #xff0c; Bitcoin could have reached that value by 2024; if I had known, #xff0c; I had to buy one, too.

而在4月19号，也将迎来比特币再次减半。减半并不是说玩家手中的比特币要被突然减去一半，而是在后续的挖矿过程中，奖励减半。他的机制就是每开采210000个区块后，奖励减半。比如以前的旷工算出来1 + 1 = 2；后，可以得到10块钱奖励，那么4月19号以后，你费电，费机器，通过算出1 + 1 = 2；后，只能得到5块钱奖励了。

And on April 19 xff0c; it will also halve Bitcoin again. Half by half does not mean that the player's bitcoin is suddenly reduced by half xff0c; half by half in the follow-up mining process xff0c; half by half. His mechanism is xff0c; half by half. For example, one & #43; 1 #61; 2xff1b; xff0c; after xff0c; after April 19; your electricity #xff0c; your machine #xff0c; by counting 1 & #43; 1 & #61; 2ff1b; ff0c; after 5 dollars.

很多人欣喜若狂，哎呀，数量要减少啦，价格又要飙升啦，赶紧入手吧。我倒觉得大可不必，他涨他的，减少啥呀减少，后续的增长减半，又不是后续从玩家手中缩减，至于价格，你信不信，你不买他就飙升，你一买那个价格曲线就调过来。我反正不买。去年有个人玩数藏被坑了50W，据说有工资，有父母的钱，还有借的，你说这不是瞎闹嘛。更糟糕的是，这小伙儿，是个程序员。

A lot of people are excited about xff0c; xff0c; quantity is going down; prices are going up again xff0c; prices are going up xff0c; let's get started. I don't think he's going to have to xff0c; he's going up his xff0c; what's going down xff0c; what's going on xff0c; what's going on xff0c; what's going on xff0c; what's going on xff0c; what's going on xff0c; what's going on xff0c; what's going on xff0c; what's going on is not going on.

1 sat

sat ，可以喊它为“聪”，当然不是他很聪明，而是有个叫“中本聪”的玩意，他是比特币的创始人，所以人们为了纪念这个“人”，将费率命名为“聪”。

Sat & #xff0c; it can be called "Hear" & #xff0c; it is certainly not he who is smart #xff0c; it is a thing called "Middle-Hear" & #xff0c; he is the founder of Bitcoin & #xff0c; so people remember this person & #xff0c; and the rate is named "Hear".

比如你这次交易需要给旷工多少钱，人们就说需要多少聪。比特币的最小单位是聪，一亿聪就等于一个比特币啦。如果你有空余时间，很感兴趣，可以来一聪试试水。所以每聪表示0.00000001BTC。

For example, how much you're going to pay for truancy xff0c; people say how much. The smallest unit of bitcoin is xff0c; 100 million is a bitcoin. If you have time left, xff0c; xff0c; you can try water. So every hearing is 0.000001 BTC.

2 获取当前比特币的价格

如果你在开发web3网站，那么肯定会涉及到获取当前比特币价格的需求。但这个价格变化非常快，几乎每秒都在波动，所以要不要频繁获取，你看自己需求而定，有时候产品会要求一分钟，十分钟这样。

If you're developing web3 & #xff0c; then there's certainly a demand for the current bitcoin price. But this price changes very quickly xff0c; it fluctuates almost every second xff0c; so you want to get xff0c more frequently; you see your needs xff0c; sometimes the product requires a minute xff0c; 10 minutes.

获取代码如下：

The following codes are obtained: xff1a;

这个price 字段就是需要获取的价格

This price

3 封装获取价格方法?

因为这个方法是异步的，肯定会有很多地方需要使用，所以需要将方法封装起来，返回一个promise这样，当其他地方需要的时候，通过async / await 的方式获取价格，代码如下：

Because it's a step-by-step xff0c; there's bound to be a lot of places to use xff0c; there's a need to encapsulate the method xff0c; to return a promise like xff0c; xff0c when needed elsewhere; to get prices xff0c through async/await; code xff1a;

4 根据聪和比特币价格，换算美元价格

比如某一笔服务费是2000聪，那么根据聪和比特币的比例换算，看代码：

For example, a service fee of 2,000 deaf #xff0c; conversion of xff0c based on the ratio of deaf and bitcoin; look at code xff1a;

但是需要注意的是，这样换算下来，必定是一个长小数，所以需要前端用toFixed(2)来转换一下用于展示。

But what needs to be noted is xff0c; this translates xff0c; it must be a long decimal xff0c; so the front end needs to convert to match(2) for presentation.

但如果得到的这个数值还要用于计算，就需要用foFixed(2)以前的数值来计算，更精确一些。?

But this value is also used to calculate & #xff0c; a previous value infoFixed(2) is needed to calculate & #xff0c; is it more accurate?
