金融危机导致各国央行和金融机构的威信扫地，这成为人们开发替代货币的动力，他们的想法是创造一种被广泛接受的新货币，相对稳定，通过控制货币供应量来使其不受通胀的影响。比特币就是这样一种尝试。
The financial crisis has led to discrediting central banks and financial institutions, which has become the driving force behind the development of alternative currencies. Their idea is to create a new currency that is widely accepted, relatively stable, free of inflation by controlling the supply of money. bitcoin such an attempt.
比特币最迷人的地方就是挖矿了。为什么挖矿这么迷人？因为挖矿能获得比特币呗。我写这篇文章的时候比特币的价格是3900美元，如果能挖到一个区块，就能获得48750美元的挖矿收入和约6000美元的交易手续费收入，这不是非常迷人吗？
The most fascinating part of Bitcoin is mining. Why is mining so charming? Because mining can get bitcoin. When I wrote this article, bitcoin was worth $3,900. If I could dig a block, I could get $48,750 in mining revenue and about $6,000 in transaction fees. Isn't that fascinating?
答案很简单，随便捡块石头，然后说服大家这可以用来换东西，再激励更多人加入进来一起用。但这个过程中要让大家都认可不是简单的事情，黄金一开始也只是块石头，它最终被大家当成钱经过了成百上千年的时间。
The answer is simple, pick up a stone, then convince everyone that it can be used to change things, and then inspire more people to join in. But in doing so, let everyone agree that it is not a simple thing, that gold is just a rock at first, and that it has been seen as money for hundreds of years.
比特币产生于2008年--一个幸运的时间，因为那刚好是金融危机的元年，传统的货币信誉受损。它由中本聪设计，这是个笔名，很可能还有一群其它的设计者。他们设计了一个复杂的算法，你用电脑去破解它就会产生比特币（也就是所谓的挖矿），当你的电脑完成了一定的任务后，一枚新比特币就会被创造出来。最初这些工作很容易完成，只要用你的笔记本就能很快生产一堆的比特币。但是他们很聪明，不能让货币被无限量地创造出来，因为如果这么做就成了无限的通胀。随着越来越多的比特币被创造出来，你的电脑就需要做更多的工作才能创造出新的比特币，最终大约到2040年，比特币的总量会永远限制在2100万枚。
Bitcoin originated in 2008 -- a lucky time, because it coincides with the financial crisis, and the traditional currency reputation is damaged. It was designed by China-Hear, a pen name, and probably by a group of other designers. They designed a complex algorithm . When your computer has done a certain task, a new bit of bitcoins is created, and you can produce a pile of bitcoins very quickly with your notebook. But they're smart, they can't make an unlimited amount of money >blank'/u' < > < > >, because if they do this, they're going to create a lot more than two million pieces of coins in 20 years, and if they do it, they're going to create a lot more than two hundred dollars in every year.
所以一开始拥有比特币的人很幸运，他们很容易就能得到比特币，当越来越多的人想要，比特币价格上涨，他们就发了。
So the people who had bitcoin at first were lucky that they could easily get bitcoin, and when more and more people wanted it, the bitcoin went up, they did.
为了保护和运行一个支付系统而消耗能源并不是一种浪费。和其它任何支付服务一样，使用比特币会产生处理成本。运行目前流行的金融系统必需的服务，比如银行，信用卡和运钞车，也消耗大量能源，虽然它们消耗的能源总量不像比特币那样是透明，也不易度量。
As with any other payment service, the use of bitcoin can generate processing costs. Services necessary to run the current popular financial system, such as banks, credit cards, and money-cars, also consume large amounts of energy, although the total amount of energy they consume is not as transparent as bitcoin and is not easy to measure.
比特币挖矿原理的设计使其可以通过使用专门的硬件随着时间推移优化挖矿过程，从而消耗较少的能源。而挖矿的运行成本依然与需求成正比。当比特币挖矿竞争变得过于激烈且收益减少时，一些矿工会选择停止活动。此外，所有挖矿消耗的能源最终都转化为热能，而利润最多的矿工正是那些可以很好利用热能的人。一个*3的高效挖矿网络不会消耗任何额外能源。尽管这是一种理想情况，挖矿的经济原则就是个体矿工都朝着这一理想状况而努力。
Bitcoin mining principles can be designed to consume less energy over time by using a special hardware /a>. The operational costs of mining are still proportional to demand. When Bitcoin mining competition becomes too intense and yields are reduced, some mining unions choose to stop their activities. Moreover, all mining energy consumed is ultimately turned into heat energy, and the most profitable miners are those who can make good use of it.
在比特币的早期，任何人都可以利用他们计算机的中央处理器寻找新的区块。随着越来越多的人开始挖矿，寻找新区块的难度大幅提高，以至于目前*10有成本效益的方法就是使用专门的硬件。你可以访问比特币官方网站获得更多信息。
In the early days of Bitcoin, anyone can use the center of their computer processor >/a> to find new blocks. As more and more people begin to dig, the difficulty of finding new blocks has increased considerably, so that the cost-effective way to do *10 is to use specialized hardware.

用户可以购买比特币，同时还可以使用计算机依照算法进行大量的运算来“开采”比特币。那么需要如何开采呢？在最初时，比特币是通过计算机的CPU来进行开采的，当你的CPU挖出了一个区块，你就获得了一定量的比特币。目前，开采的方式基本已经由CPU转为了GPU，因为对于GPU来说其计算方式更适合用来挖矿，速度也要比CPU快十倍或更多。
Users can buy bitcoins, and use computers to do a lot of maths to “exploit” bitcoins. So how does it need to be mined? Initially, bitcoins were moved from CPU to CPU CPU for mining purposes. Currently, the method of mining has been shifted from CPU to GPU, because it is much more appropriate for GPU to dig mines and is also ten times faster or more faster than the CPU.
