说到以太坊挖矿相信大家除了成本最关心的就是利润，以太坊挖矿的原理其实不难理解，以太坊是一本大账本，每发生一次交易，需要有人来记账，而参与记账的过程就会获得报酬，报酬就是以太坊。所以记账的权利是需要大家来抢的，而我们所说的以太坊挖矿就是抢夺记账权，谁的算力大，记账速度快，谁就更有可能抢到这个记账权，所以说能否挖到更多的以太坊，就需要你的挖矿机为这个全网记账能提供多少算力。
Speaking of Ether's mining, which is believed to be about profits in addition to the cost, it is easy to understand that Ether's mining rationale is that it is a big book of accounts, that for every transaction, someone needs to be taken into account, and that it is Ether that will be paid to participate in the accounting process. So the right to account is to be taken by everyone, and what we call Ether's mining is to rob the account, and who has the power and the speed of accounting, is more likely to get the account, so if you can dig more, you need your miner to give the whole net the credit.
为了正确地回答这个问题，让我们从头说起：先假设一台挖矿设备，然后使用合理的数据，再经过实际分析，看看以太坊挖矿可以赚到多少钱。
In order to answer that question correctly, let us start from the beginning: to assume a mining facility, then to use reasonable data and then to actually analyse how much money Ether's mine can make.

1.挖矿成本的假设
1. Assumptions of mining costs
你可以看到，这个虚拟的挖矿设备比市面上现有的较好的挖矿设备更高效，更赚钱。我们假设有4个GPU，每个的挖矿能力为40MH/s。硬件的规格为：4个GPU、1个处理器、1个主板和1个1000瓦的电源。这个挖矿设备的成本大约是3千美元。
As you can see, this virtual mining facility is more efficient and more profitable than the better mining equipment available on the market. We assume that there are four GPUs, each with a capacity of 40 MHz/s. The hardware specifications are four GPUs, one processor, one main board and one 1,000-watt power source. The cost of this mining facility is about $3,000.

一般电费大约是每千瓦时10美分，这个数据来源于美国国家平均电费价格。为了运行挖矿设备，每小时至少需要为每千瓦支付10美分。这意味着每天挖矿所需的电费是2.4美元。
General electricity costs are about 10 cents per kilowatt hour, a figure derived from average electricity prices in the United States. In order to operate mining equipment, a minimum of 10 cents per kilowatt per hour is required.
我们还需要在这基础上加上2020年1月的区块奖励和区块难度。我们假设在矿池工作的时候仅可使用一台设备。有些矿池征收10%的费用，好点的只收1%。所以我们取中间值1.5%。
We also need to add on this basis block
我们从Etherescan的历史图表上截取几个点作为难度系数，然后运行一次指数回归，就可以得到指数增长系数，它反映了以太坊挖矿的难度增长情况。 We take a few points from Etheescan's historical chart as a difficulty factor, and then run an index regression, and we get an exponential growth factor, which reflects an increase in the difficulty of digging mines in the Taikus. 2.区块

根据这个函数，我们得出了下列值，用于描述难度函数未来值的预测曲线。 Based on this function, the following values have been derived to describe the forecast curve for the future value of the difficulty function. 3.以太生态
利用区块难度的增长，我们可以算出一年后，难度系数将从2,280,210,891,539,710增长到11,880,071,363,893,300。此难度系数是根据上面拟合的难度函数计算的，并假定这个函数也适用于未来的难度系数。
Using the difficult growth of , we can calculate that, after a year, the difficulty factor will grow from 2,280,210,891,539,710 to 11,880,071,363,893,300. The difficulty factor is calculated on the basis of the difficulty function proposed above and is assumed to apply also to future difficulties.
区块难度与以太坊挖矿的设备产生的利润成反比。这意味着，随着每天难度的增加，设备的利润会下降。
最终，设备赚的钱不够支付运行所需的电费。到时就必须关掉设备了，因为你会赔钱。 Eventually, the equipment doesn't make enough money to pay for the electricity needed to run. 借用CoinWarz的挖矿利润计算器，输入一个不断增长的区块难度，我们发现仅需要一年的时间每天的利润就从18.24美元降到1.60美元。这个计算器使用的输入信息有：hash速率(MH/s)、功率(瓦)、电费单价(美元/千瓦时)、难度、区块奖励、矿池收费、ETH到BTC的兑换率、BTC到美元的兑换率，以及硬件成本。对于利润预测函数，我们用这个计算器每个月计算一个点，并假定每两个点之间是线性的。 Using CoinWarz's mining profit calculator to enter a growing block, we find that the daily profit will fall from $18.24 to $1.60 in just one year. The calculator uses input information such as: hash speed (MH/s), power (watt), unit price of electricity (US$/kWh), difficulty, block incentive, pit charge, ETH-BTC exchange rate, BTC-US$ exchange rate, and hardware cost. For a profit projection function, we use this calculator to calculate a point per month, assuming that it is linear between two points. 根据这个计算器，如果从2020年1月开始，1年半(476天)后以太坊挖矿设备的运行费用将超过产生的利润(假设以太坊的价格是固定的)，然后就会开始赔钱。 According to this calculator, a year and a half (476 days) after January 2020, the operating costs of the mine-mining equipment at the Taiyet will exceed the profits generated (assuming that the price at Taiyem is fixed) and then begin to pay for it. 最后到挖矿设备关闭为止，总计获得的利润为2,916.59美元。但是，回顾一下本文开头，我们计算过投入的成本大约为3000美元，所以不难发现实际上是有点赔钱的。当然你可以把GPU卖掉收回一些成本，但是二手设备会大幅降价，而且随着新挖矿设备以惊人的速度更新换代，旧设备的降价只会加剧，一年半前购买的GPU基本已丧失了大部分价值。最终GPU的出手价格将决定此次挖矿整体的投资回报。 Finally, until the mining facility was shut down, the total profit was US$ 2,916.59. But, looking back at the beginning of this paper, we calculated that the cost of the input was about US$ 3,000, so it is easy to find that there is actually a price to pay for it. Of course, you can sell the GPU, but second-hand equipment will be significantly reduced, and the price of the old equipment will only increase, with the new mining equipment being replaced at an alarming rate, and the GPU purchased a year and a half ago will lose much of its value. 想想看，一个600美元的GPU，一年50%的折旧率已经算相当不错了。如果你以每个300美元的价格卖掉GPU，那么总共可以获得1200美元，于是总计收入为4,116.59美元，这意味着利润为1,116.59美元，大约是37%的回报率。 Just think of a $600 GPU, 50% depreciation per year is pretty good. If you sell GPU at $300 a year, you get a total of $1,200 and a total income of $4,116.59, which means a profit of $1,116.59, which is about 37% return. 看看亚马逊你就会明白GPU的价格很容易就会贬值到100美元以下。即便按照100美元计算，总共可以收回400美元，那么整体的收入为3,316.59美元，利润为316.59美元，回报率大约为10.5%。 When you look at the Amazon, you realize that GPU prices easily depreciate below $100. Even if a total of $400 can be recovered at $100, the overall income is $3,316.59, profit is $316.59 and returns about 10.5%. 在计算过程中，我们所用的电费成本虽然比较实惠，但不算太理想。看看下列3个例子，其中一位矿工来自康涅狄格州，一位来自华盛顿，再加上我们的假设挖矿设备： In calculating the cost of electricity that we use, though more economical, it is not ideal. Look at the following three examples: one miner from Connecticut, one from Washington, plus our hypothetical mining equipment: 一、准备工作 I. PREPARATIONS ETH挖矿主要是使用显卡来挖矿。需要配置一台PC来运行挖矿程序，主要硬件包含：显卡，主板，电源，CPU,内存，硬盘(推荐60G以上SSD)，延长线、转接线等。其中显卡决定了挖矿的速度，主板、电源很大程度上决定矿机运行的稳定程度。 ETH digs mostly with a visible card. The main hardware is: a visible card, a master plate, a power source, a CPU, a memory, a hard disk (recommends 60 G above SSD), an extension line, a switch, and so on. The card determines the pace of mining, and the main plate, the power source and, to a large extent, the stability of the mine machine. 二、硬件准备 II. Hardware preparation 主板建议：显卡挖矿不需要很大的PCIE带宽，主板上具备PCI-E 1X即可满足带宽要求。一般主板上具有3-5个PCI-E 1X接口，1个PCI-E16X接口，此外主板上具有大4PIN供电接口对稳定性有一定的提升。PCI-E1X需要淘宝购买1X转16X延长线。 The master board recommends that a large PCIE bandwidth is not required for card mining, and that PCI-E 1X is available on the main board to meet bandwidth requirements. There are three to five PCI-E 1X interfaces on the general board, one PCI-E16X interface on the main board, and the large 4PIN power supply interface on the main board has a certain increase in stability. 推荐型号： Recommended model: 三、钱包

The system is the best of win764 places to build the use of the official original system. The latest version is driven by mining
2、挖矿软件
2. Mining
挖矿软件
Mining software //a> contains ethminer and Stratum Proxy. Ethminer obtains assignments and digs in the form of getwork. Stratum Proxy converts the getwork agreements into Stratium agreements, connecting the mine pool and providing stable and rapid getwork connections for LAN miners.
使用Stratum Proxy会减少丢包和延时，并提供矿池备份设置，提升收益10-20%。由于ETH每16秒一个区块，挖矿软件也不完善，目前通过Stratum Proxy的拒绝率在4-5%，getwork协议在10%以上。
The use of Stratum Proxy will reduce the drop and delay and provide back-up settings for the pits, raising the returns by 10-20%. Since ETH has software is also incomplete, with a current rejection rate of 4 to 5 per cent through StratumProxy and a rate of over 10 per cent through the Getwork agreement.
首先修改eth-proxy.conf中的收款地址和掉线报警邮箱，矿池地址等;运行eth-proxy.exe;
