27万一枚的比特币，家用电脑24小时挖矿，需要多久才能挖到一枚？

　　当前国际形势紧张，在各方经济制裁下卢布暴跌，国际油价暴涨了7%左右，避险资产一时成为许多投资者的目标。要说传统避险资产，非黄金莫属，如今黄金、谷物、原油等一路飙升。实际上，还有一种对冲风险资产，被称为“数字黄金”，它就是比特币。

The current state of international tension is characterized by a sharp fall in rubles under economic sanctions on all sides, a sharp rise in international oil prices of around 7%, and the targeting of risk-free assets for many investors at a time. To speak of traditional hedge assets, other than gold, gold, grain, crude oil, etc., is now on the rise.

　　2008年，一位自称是中本聪的日裔美国人创造了电子货币——比特币，没有人见过他，也没人知道他到底是谁，但他创造的比特币引起了资本市场的高度关注。比特币也成为了近年来最为火爆的投资之一，缔造了无数财富神话。一枚比特币的巅峰时价值5.8万美元，而比特币的总市值超过了1万亿美元，比世界上很多公司的市值还要高。

In 2008, a Japanese-American who claims to be a Chinese-blind American created electronic money — bitcoin, no one has seen him or knows who he really is — but the bitcoin that he created has attracted high interest in the capital market. Bitcoin has also become one of the hottest investments in recent years, creating countless myths of wealth. A bitcoin is worth $58,000 at its peak, while the total market value of bitcoin is over $1 trillion, higher than that of many companies around the world.

　　进入3月以来，国际经济形势处于紧张状态，使比特币的价格在来回震荡，3月5日，比特币最高交易价为4.2590万美元，最低为3.9293万美元。也就是说，比特币价格虽有下跌，但仍处于高位，以当日最高交易价来说，一枚比特币折合人民币约27万元。

Since March, the international economic situation has been tense, causing the price of Bitcoin to reshuffle, with a high transaction price of $425.9 million on 5 March, at a minimum of $392.93 million. That is to say, the price of Bitcoin, although falling, remains high, and a bitcoin is equivalent to about 270,000 yuan at the highest trade price on the day.

　　这意味着，一枚比特币就能卖到27万元，很难不令人心动。早在2017年，中国人民银行就宣布比特币是一种特定的虚拟商品，不具有法偿性、强制性等货币财产，不具有与货币相同的法律地位，并且我国也禁止比特币作为货币在市场上流通，尽管如此，还是有很多投资者想要借此机会一夜暴富。

This means that a bitcoin can be sold at $270,000, and it is hard to be unimpressive. As early as 2017, the People’s Bank of China declared Bitcoin to be a specific virtual commodity, with no legal compensation, no mandatory monetary assets, no legal status similar to that of a currency, and our country also prohibited the circulation of bitcoin as a currency on the market, although many investors wanted to take the opportunity to be rich overnight.

　　实际上，在比特币刚被创造出来的时候，它的价值还不如一个披萨。但当时仍有许多人看到了它未来的价值，李笑来就是其中一个，他在比特币诞生不久后买下了2000多枚比特币。从那以后，比特币的价值飙升，李笑来又购买了许多比特币。2017年时，他手中的比特币数量达到了10万枚，也因此被称为中国比特币第一人。

Indeed, when Bitcoin was first created, it was worth less than a pizza. But there was still a lot of people who saw its future value, one of them Li laughter, who bought more than 2,000 bitcoins shortly after Bitcoin was born. Since then, Bitcoin’s value has soared, Li laughter has bought a lot of bitcoins.

　　2017年，比特币的价值达到了1.8万美元一枚，这是它的第一个巅峰。当时，人们都以为李笑来会继续购入的时候，他却做了完全相反的选择，李笑来宣布退出币圈，并以135亿元的价格出售了所有的比特币。靠比特币发家致富的李笑来，却留下了这样一句话：“比特币完全是一个骗局”。

In 2017, Bitcoin had a value of $18,000, which was its first peak. When people thought that Li would continue buying, he made the opposite choice, and Li laughed to announce his withdrawal from the circle and sold all the bitcoins at a price of $13.5 billion. The Lee who made the fortune by bitcoin left a saying that “bitcoin is a total scam”.

　　当时很多人对李笑来说的话不理解，但比特币接下来的走势说明了一切。没有人想到，2017年一路飙升的比特币会在2018年急转直下，直线下跌80%，让无数人血本无归。2020年11月13日，比特币价格突破16000美元，这是比特币继2017年之后第二次突破一万美元，意味着比特币终于重新回到了三年前的峰值。

At the time, many people didn't understand Lee’s laughter, but the next movement of Bitcoin made it all clear. No one thought that the fast-rising bitcoin in 2017 would have fallen by 80% in 2018, leaving millions of people without blood. On November 13, 2020, Bitcoin passed $16,000, the second time after 2017, and that meant that bitcoin had finally returned to its peak of three years ago.

　　经历了一轮暴涨后，2021年年初，比特币价格又跌到了3.5万美元左右，但到了2月份又迎来了新一轮上涨，最高达到了5.8万美元的峰值。一枚比特币折合人民币约36.6万元，这意味着，只需要几枚比特币，就能够全款拿下二线城市的一套房。

After a round of surges, Bitcoin prices fell again to around $35,000 in early 2021, but a new round of rises reached a peak of $580 million in February. One bitcoin is equivalent to about $366,000, which means that only a few bitcoins are needed to take down a second-line house.

　　比特币的这一系列疯狂行为，向全世界展现了虚拟货币的高度不稳定性。据统计，短短6个月时间，比特币价值涨幅已经超过了350%，投资回报率可以说是非常高了。币圈专家认为，比特币在历史上的涨涨跌跌太正常，不过整体价值还是上涨的。

This series of crazy actions by Bitcoin shows the world a high degree of uncertainty about virtual currency. According to statistics, in just six months, the value of Bitcoin has increased by more than 350%, and the return on investment can be described as very high.

　　这么大的诱惑力，吸引着越来越多的人想要分一杯羹。但对普通人来说，一枚比特币就要数十万，门槛太高了，早已超出了普通人的承受范围，于是他们就选择了另一种获取比特币的方式——“挖矿”。那么对于普通人而言，如果用家用电脑24小时不停的挖矿，多久才能挖到一枚？

But for ordinary people, a bitcoin is hundreds of thousands, and the threshold is too high for ordinary people, so they choose another way to get bitcoin – the “mining of mines.” So, for ordinary people, how long does it take to dig a mine 24 hours a day with a home computer?

　　比特币本质上是一种具有加密属性的虚拟货币，而“挖矿”就是用电脑不停计算，解决基于加密哈希算法的数学难题，通过创建新的区块来获取交易费用，也就是比特币。原理很简单，但实际操作起来很难，因为需要电脑进行大量数据计算。随着参与人数增加，运算也会更复杂，庞大的数据也会令电脑高负荷运转，因此用来挖矿的电脑必须要具备超强算力。

Bitcoin is essentially a virtual currency with encryption properties, and “mining” is a computer-based, non-stop calculation that solves the mathematical problems based on crypto-Hashi algorithms by creating new blocks to capture transaction costs, i.e. bitcoin. The rationale is simple, but it is difficult to actually do it, because it requires a lot of data to calculate. As the number of people involved increases, it will be more complicated to do so, and huge data will run high on computers, so computers used to dig mines will have to be super-calculatory.

　　据了解，目前市面上的专业矿机算力几乎都在50TH/S以上，功率高达3250W，

It is known that almost all of the specialized mining machines currently on the market are more than 50 TH/S, with a power of 3250 W,

　　大都由显卡阵列组成，显卡数量多达上百个。而普通的家用电脑，算力大概在1000H/S，目前，比特币的计算难度已经达到21434亿，这么庞大的高负荷数据计算，普通电脑根本承受不了。

Most are made up of visible card arrays, with hundreds of cards. And the average home computer, with about 1,000 H/S computing power, is currently 214.3.4 billion dollars in difficulty in calculating that huge load of data, and the average computer can't afford it.

　　即便能够承受，但挖矿速度肯定会慢上许多。假如一台家用电脑能够在高负荷的情况下持续运转，一天时间能挖到0.0018个比特币，而想要获得一枚比特币，则需要24小时不停运转556天，并且这500多天里不能出任何问题。但实际上，一台家用电脑在不停工作之下，恐怕几天的时间便要报废，能不能坚持500多天还得另说。

If a home computer can continue to operate at a heavy load, and can dig 0.0018 bitcoins in one day, it will take 24 hours to get a bitcoin, 556 days, and there will be no problems for more than 500 days. But, in fact, a home computer will have to be scrapped in a few days, and it will have to be more than 500 days.

　　即便是对于专业矿机来说，想要回本，也需要大约1年时间左右，并且专业矿工使用的是专门的设备来挖比特币，这些机构设备的计算能力更强，效率也远高于家用电脑。因此，想要通过家用电脑挖比特币是不切实际的。

Even for specialized miners, it takes about a year to get back, and professional miners use specialized equipment to dig bitcoins, which are much more computing power and more efficient than home computers. It is therefore unrealistic to want to dig bitcoins through a home computer.

　　因为比特币的数量并不是无底洞，随着参与挖掘的人数增多，运算也会越来越复杂，全网算力自然会增加，而挖到比特币的难度也大大提升。为了控制比特币的总量，其发行量固定在2100万枚，每过四年，能挖出的比特币数量就会减少。并且在挖矿过程中，高额的电费就让很多人吃不消了。

Because the number of bitcoins is not a bottomless hole, and as the number of people involved in digging increases, it becomes more complex to calculate, and the ability to dig for bitcoins increases naturally. To control the amount of bitcoins, their circulation is fixed at 21 million, and the number of bitcoins that can be dug is reduced every four years.

　　其实在比特币还没有爆火之前，的确有人使用家用电脑挖到了大量比特币，毕竟当年全网算力很低，一般的台式电脑都能挖矿。但随着比特币价值增加，挖矿难度自然也增长了无数倍，所以现在再想用家用电脑挖矿完全是天方夜谭。因此，想要凭借比特币实现一夜暴富的想法，并不现实。对于比特币，大家又有什么看法呢？

Indeed, before Bitcoin started to explode, a large amount of bitcoin had been dug up using a home computer, after all, with a low net capacity and a normal desktop. But, as Bitcoin’s value increases, the difficulty of mining increases exponentially, so now that it is entirely natural to try to dig a mine with a home computer. So it is not realistic to want to use bitcoin to make one night rich. What do you think about bitcoin?
