购买以太坊挖矿机划算吗？以太坊矿机挖矿真实收益

购买以太坊挖矿机划算吗？在回答这个问题之前，币圈子小编先跟大家聊聊以太坊挖矿，挖矿是指通过专用的矿机,耗费电量进行大量计算得出符合一定条件的数字代码,而这串数字代码就是我们大家所熟知的数字货币，而以太坊挖矿是指矿机计算出来的数字代码就是以太坊，了解完以太坊挖矿之后回归正题。

Does it cost to buy a pit miner? Before answering this question, the coin ring editor first talks to you about the pit mine, which is a code for numbers that meets certain conditions, which we all know as a digital currency, which is a code calculated by a miner, that is, that is, that is, that is, that we get back to business when we're done with a dedicated miner.

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 to this the block incentive and block difficulty of January 2020. We assume that only one device can be used while working in a pond. Some ponds charge 10 per cent, while the good ones charge only 1 per cent. So we take the median of 1.5 per cent.

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.区块难度增长函数

2. Block Difficulty Growth Functions

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.以太生态系统的假设

3. Assumptions of too-ecosystems

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。

Taking advantage of the difficulty of blocks, we can calculate that the difficulty factor will increase from 2,280,210,891,539,710 to 11,880,071,363,893,300 a year later. The difficulty factor is calculated on the basis of the difficulty function to be combined above, assuming that the difficulty factor will also apply to the future.

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。

The difficulty of blocks is inversely proportional to the profits generated by equipment used to dig mines in the underworld. This means that the profitability of the equipment will decline as it becomes more difficult every day.

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:

以太坊的一个区块大概时间是13秒，会根据区块的运算速度进行调节，所以导致一个区块一个难度一个产出，以太坊的产出是动态的需要实时查询，平台会根据每日矿池分配按照持有的算力进行分配!

One block of the Ether chamber, approximately 13 seconds in time, will be adjusted according to the speed of calculation of the block, which leads to a difficult output, a real-time search with a dynamic output of the ether chamber, and the platform will be distributed according to the daily mineral pool distribution according to the capacity held!

1.产出：0.0001ETH/Mhs(每个区块产出各不相同);

Outputs: 0.0001ETH/Mhs (with different outputs per block);

2.管理费：0.0249usdt-(0.0249usdt*6%*0)不收取管理费;

2. Management fee: 0.0249usdt-(0.0249usdt*6 per cent*0) does not charge a management fee;

3.电费;0.008usdt/Mhs/天*6折=0.0048usdt/Mhs/天(电费6折);

3. Electricity charge; 0.008 USdt/Mhs/day = 0.0048USdt/Mhs/day (or 6 per cent);

4.产出收益：0.1ETH-0.0048usdt=0.0201usdt(统一产出减去电费=每天收益);

Output gains: 0.1 ETH-0.0048usdt = 0.0201usdt (harmonized output minus electricity costs = daily benefits);

币圈子小编提醒投资者，在购买以太坊挖矿机的时候，一定注意防骗，尤其是那种能从各种渠道看到一些前所未闻的矿机品牌，但始终找不到任何购买渠道，又或者开售时间模棱两可，遥遥无期，其实这样的情况大多数都是矿机未实现量产，甚至根本就没有研发出来，甚至有的矿机商家还要求投资者提前交订金若是遇到这样的矿机品牌，币圈子小编建议投资者不要购买，因为这样的情况多半是骗局。

The small editor of the ring reminds investors that when buying Ether machines, they must be wary of fraud, especially when they can see some of the previously unknown mine brands from a variety of sources, but never find any procurement channels, or when they are sold ambiguously and for a long time. In fact, the majority of such cases are cases in which the mine machine has not been produced and has not even been developed at all, and even some of the miners ask investors to make advance deposits in the event that they meet such machine brands, the small editor of the ring advises investors not to purchase them, because most of the cases are fraudulent.
