比特币价格涨到9万，用家庭电脑挖矿，一天能赚多少钱？

虽然受到疫情影响，比特币价格持续低迷，但随着比特币产量的第三次减半，比特币的价格一路高涨，迎来了一个新的起点。

Although affected by the epidemic, bitcoin prices continued to fall, with the third halving of Bitcoin production, the price of bitcoin rose all the way to a new starting point.

截止到10月31日，比特币的价格已经从3月份最低的5331美元，涨到了如今的13701美元，折合人民币约91700元，未来突破10万大关也不是没有可能。

As of 31 October, the price of Bitcoin had risen from a low of $5331 in March to $13001 today, equivalent to approximately $91,700, and it was not impossible to break the 100,000 mark in the future.

值得一提的是，“产量减半”是中本聪写比特币代码时所规定的必然事件，在比特币协议中规定，全世界比特币总量为2100万枚，而每产生21万个区块后，出块奖励的比特币数量将减少一半。

It is worth mentioning that “50 per cent of production” is a necessary event when China is writing the bitcoin code, which in the Bitcoin agreement provides for a total of 21 million bitcoins worldwide, while the number of bitcoins awarded will be halved for every 210,000 blocks generated.

说白了就是现在的比特币获取难度加大了，导致比特币变得更为稀有，所以在今年5月12日的“产量减半”之后，比特币开始逐渐升值。虽然其价格上涨幅度没有第一次和第二次“产量减半”的变化高，但可以肯定的是，比特币确实比原来更加值钱了，而且现在正在往好的方向发展。

To be sure, Bitcoin is indeed more valuable than it was before, and is now moving in the right direction, as Bitcoin began to appreciate gradually after the “half of its production” on May 12th of this year. Although the price increases were not as high as the first and second “half of its output.”

产量减半之后，挖矿生意有点难

It's a bit difficult to dig after half the production.

众所周知，比特币是一种p2p形式的网络虚拟货币，具有“去中心化”的特性，而且由于他总量有限，获取难度高，所以一枚比特币的价值堪比“黄金”。而我们常说的“挖矿”其实就是比特币挖矿，也就是利用电脑硬件计算出比特币的位置并获取它的过程。

It is well known that Bitcoin is a virtual Internet currency in the form of p2p, with a “decentralized” character, and that because of his limited volume and difficulty of acquiring it, a bitcoin is worth more than “gold.” And what we often say is that bitcoin digs, which is the process of using computer hardware to calculate the location of bitcoin and acquire it.

所谓有钱就有生意，在比特币高价值的诱惑下，也带动了“挖矿”行业的发展，一大批矿工由此诞生。不过比特币现在虽然更值钱了，但随着比特币奖励减半，矿工们的收入似乎要“大打折扣”。

The so-called rich have a business, which, under the temptation of the high value of Bitcoin, has also led to the development of the “mining” industry, which has led to the birth of a large number of miners. But, while Bitcoin is now more valuable, as the Bitcoin reward is reduced by half, it seems that the miners’ income is “highly reduced”.

今年10月19日，区块链数据追踪分析平台Glassnode显示，比特币矿工收入急剧下降，达5个月低点，日平均值达29.956 BTC（约30枚比特币），较9月中旬缩水超90%。

On 19 October of this year, Glasnode, the block chain data tracking and analysis platform, showed that the income of Bitcoin miners had fallen sharply to a low of five months, with a daily average of 29.956 BTC (approximately 30 bitcoins), which was more than 90 per cent smaller than in mid-September.

据了解，自从比特币产量减半之后，比特币矿工收入与过去相比降了大概30%。甚至有媒体分析称，由于利润降低，近三分之一的比特币采矿场可能关闭采矿机。

It is known that after halving Bitcoin production, Bitcoin miners’ revenues have fallen by about 30 per cent compared to the past. Even media analysis suggests that nearly one-third of the Bitcoin mines may close down because of lower profits.

不管其消息是否真实，但比特币矿工现在的日子确实不如以往了。

Whether the news is true or not, it is true that Bitcoin miners are living in worse times than ever before.

家用电脑能挖矿赚钱吗？

当然，做任何生意都是有风险的，对于专业的挖矿企业来说，比特币虽然产量降低了，但由于比特币价格上涨，此消彼长下，他们还是有利可图的，只不过稳定性较差。因为受到运营成本、电费和比特币价格的影响，这些“矿企”的收入也是随时都会变的。

Of course, doing any business is risky. For professional mining companies, even though their output is lower, they are profitable and less stable because of the price of bitcoin. The revenues of these “miners” will change at any time because of operating costs, electricity costs, and bitcoin prices.

相比之下，个人挖矿似乎是个不错的选择，因为我们不用像企业那样，投入那么多的成本，风险非常低。那么个人挖矿这件事情真的靠谱吗，我们能靠“挖矿”赚钱吗？

Personal mining, by contrast, seems a good option, because we don't have to put so much money into it like business, and the risks are very low. Is it really true that we can make money from mining?

在我们挖矿之前，需要注意的是，“挖矿”方法听起来虽然很简单，只需要有一台电脑下载挖矿软件，然后去运行特定算法就行了。不过“比特币挖矿机”有专业的挖矿芯片，多采用安装大量显卡的方式工作，其算力不是我们常用的普通电脑可以比拟的。

Before we dig, it is important to note that the “mining” method, though simple, only needs a computer to download the mining software and run a particular algorithm. But the “bitcoin mining machine” has a professional mining chip that works more with a large number of visible cards, and the calculus is not comparable to the normal computers we usually use.

我们常说的算力，其实就是每秒可以计算多少个哈希（hash）值，算力越高，每秒计算的哈希值就越大。

What we're talking about is the number of Hash values that can be calculated per second, and the more they can be calculated, the bigger they can be.

根据巴比特今年7月份的数据，目前比特币全网算力约为127.72EH/s。一台芯动矿机T3T，每秒能计算5.7*10的13次方的哈希碰撞；而一台普通的电脑最多也就是每秒1000次，其算力与专业的比特币挖矿机有着天壤之别。

According to Babbitt's data for July of this year, the full net capacity of Bitcoin is currently around 127.72EH/s. A core miner T3T, which calculates the 13-dimensional Hashi collisions of 5.7*10 per second, while a normal computer, at most 1,000 times per second, is very different from a professional bitcoin miner.

据了解，一台芯动矿机T3T一天大概能获得0.001126枚比特币，假设一切顺利，抛开外在条件影响的话，它大概需要888天才能挖到一枚比特币。

It is understood that a core miner, T3T, would be able to get about 0.0001126 bitcoins a day, and it would take about 888 days to dig up a bitcoin if everything went well and if external conditions were to be removed.

那么可想而知，与专业挖矿机算力相去甚远的家用电脑，其能挖到比特币的几率非常渺茫。而且目前总量仅为2100万个的比特币，已经被开采了80%以上，剩下可挖的比特币越来越少，这意味着挖矿难度也越来越高。所以综合来看，想用家用电脑挖比特币的话，一天甚至一年的收入都将极大概率为零。

So, as you can imagine, the odds of digging into bitcoin are very slim for a computer that is so far out of hand with a specialized miner. And now, with a total of only 21 million bitcoins, more than 80% of the bitcoins have been mined, leaving fewer and fewer bitcoins, which means that mining is more and more difficult.

而且值得一提的是，用家中的电脑挖矿有一定的危险性，因为挖矿需要电脑日夜不停地运转，对电脑硬件有着非常大的伤害，很容易出现问题，所以建议大家还是放弃用家用电脑挖矿的想法，如果显卡“爆炸”的话可就得不偿失了。

It is also worth mentioning that mining with a home computer is dangerous, because mining requires that the computer operate day and night, that it is very damaging to computer hardware and that it is easy to come up with problems, so it is suggested that we abandon the idea of mining with a home computer, and that if the card is “exploitated”, it would be worth it.

总的来说，比特币虽然价格一路高涨，隐隐有突破10万元的意味，现在挖矿囤币是最便捷快捷的方式，挖矿是从一级市场上去获得比特币！

In general, even though the price of Bitcoin has risen all the way, implying a breakthrough of $100,000, mining is now the easiest way to hoard it, and mining to get bitcoin from the first level of the market!
