3080it computing power
21.5 * 3600 seconds * 24 hours = 1857600 M / day
1857600 / 1024 / 1024 = 1.7715 T / day
a t of computing power / day can dig bitcoin worth 4.03 yuan
1.7715 * 4.03 = 7.14 yuan / day
since 2017, bitcoin has reached new heights. Yesterday (May 23), the value of bitcoin broke through the ￥ 16000 mark, hyping virtual currency, becoming a matter that the general public can participate in, And a little bit of technical level, both fried money, but also began to have the technical content of mining
as we all know, virtual currency has a numerical peak, the more difficult it is to dig. In fact, it's hard to judge whether to lose money or not if we continue to dig. Therefore, in the end how to dig, dig what can be the fastest back to this, this paper studies the above two core issues based on the current market situation
The most advanced bitcoin mining machine, one to two years to dig out a bitcoin, bitcoin mining is now too difficult. If you want to dig, you can dig ether currency. Now it is steadily appreciating every day. According to the current development trend, it will be able to recover its capital in about seven months, and then it will be profitable< br />
Bitcoin is a kind of network virtual currency. Bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system. Assuming that the mining computing power is 100 mhash / s and the total computing power is 4000 ghash / s per day, 3600 bitcoins can be g out every 24 hours
China's computing power has accounted for more than 75% of the world, that is to say, 75% of bitcoin in the world is made in China. How long does it take to dig a bitcoin
bitcoin used to be very good at "digging", which can be done by ordinary computer CPU, and it can automatically "solve problems" by downloading software. But with the rise of currency price, more and more people want to "solve the problem", and the difficulty of mining is also increasing. Now, the amount of computation needed to dig a bitcoin is beyond the reach of ordinary people. Ordinary computers can't afford it
instry insiders said that in 2014, 100 bitcoins were generated from 500000 yuan of electricity charge per day, and the cost of electricity charge alone was 5000 yuan per coin. But now, the same cost has more than doubled, and the electricity cost of each bitcoin is as high as 10000 yuan
in the generation mechanism of bitcoin, mining reward is decreasing. At the beginning of the birth of bitcoin, the miners could get 50 bitcoins for each page of the ledger, and then 25 bitcoins for each page of the ledger, decreasing in turn. It's like digging gold. At first, it's more and less. The time point at which each new reward is reced by half is called half bitcoin proction
assuming that the mining computing power is 100 mhash / s, the total computing power is 4000 ghash / s per day in 2014, and 3600 bitcoins are g out every 24 hours
now, we can understand the difficulty of bitcoin digging in this way, which is equivalent to 100 million dice throwing numbers less than 100 million and 50 million. Whoever throws them first will get the bookkeeping right. At this point, 1050 million is a hash value. The process of throwing dice is called hash collision. The unit of mining power is the number of hash collisions per second
at present, the computing power of bitcoin in the whole network has reached 2.36 billion hash collisions per second, which is equivalent to the number of water droplets in more than 200000 50 meter long standard swimming pools. But even with such a large amount of computing power, it will take about 10 minutes to hit a hash value that meets the requirements
in 2012, bitcoin's output was halved for the first time, and in July 2016, bitcoin's output was halved for the second time. At present, 12.5 bitcoins are awarded for recording one page of account book. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, with a total of 21 million

According to the current computing power of the whole network, it takes 54436.5t of computing power to dig a bitcoin 24 hours, that is, one bitcoin a day< it requires 746 mining machines with the latest 73t capacity on the market to work together for 24 hours
the cost of mining mainly includes (mining machine cost / power cost). Now the latest miner is 22650 yuan, a miner consumes 77 kwh per day. At present, the price of mining machinery on the market is about 0.36 yuan, 28 yuan per day. The cost of mining bitcoin = mining machine price (22650)
mining bitcoin requires a professional site "mine" to place mining machines. The construction cost of placing about 3000 mining machines in a small professional mine is about 300 watts

unable to mine at home
the noise of 60-80 decibels will be proced by the mining machine in the working process. Mining at home is not feasible, the miner needs 24 hours of endless operation, so the temperature of the miner will be very high, the maximum temperature can reach 80 degrees. Therefore, mining needs a good environment to rece the temperature. Household electricity and electricity charges are high, and the cost is higher than the income. In addition, mining has a certain degree of professionalism, professionals need to carry out certain operation and maintenance to ensure the normal operation of the mining machine
the key to rece the mining cost is to purchase mining machines in batches and low electricity charges. Professional mine is built to ensure the operation of mining machinery. At present, the mainstream mining machinery manufacturers are bitcontinental Technology Co., Ltd. in Beijing and Jianan Yun Technology Co., Ltd. in Hangzhou. Mining machinery is proced in the form of appointment in futures. It is difficult for indivials to buy Mining machinery in small quantities on the official website. After years of development, the mining machinery market has formed a complete instrial chain. The price of mining machinery fluctuates with the price of money, and the power resources are basically distributed in the cheap western region. Getting cheap electricity prices requires personal resource advantages
the budget of this set is almost 8000, which is likely to be won. Now we mainly wait for 3080 to be officially put on sale, otherwise the price can not be estimated, because there will be differences in the prices of different brands at that time. If the budget is insufficient, then we have to choose the second and third tier brands. I've written so much about this problem, please don't forget to praise and pay attention to it. Thank you
next, I recommend a more balanced configuration with 3080. In terms of positioning, 3080's performance is more than 2080ti, so it should be a flagship graphics card, and other accessories should not be too bad. If it's too bad, I'm sorry for such a good graphics card. As for the budget, I can't estimate it. As for 8000, it's impossible to meet it. The price trend can only be seen later, I dare not promise you now
the budget of this set is almost 8000, which is likely to be won. Now we mainly wait for 3080 to be officially put on sale, otherwise the price can't be estimated, because the price of different brands will certainly be different at that time. If the budget is insufficient, then we have to choose the second and third tier brands. I've written so much about this issue, please don't forget to praise and pay attention to it. Thank you
the energetic young sailor Edmond Dants is an honest young man. He originally had a peaceful life and a beautiful fiancee, Merc è s, but it was crushed by others' jealousy - just when they were about to hold a wedding, Edmond's good friend, fernander, framed him in order to win Mercedes. His innocent self is in prison, and his fiancee is in the arms of his enemies. All these completely subvert Edmond's values and right and wrong concepts, and change his view of the world. Fortunately, thirteen years of nightmare like prison life did not destroy Edmond's body and mind. On the contrary, it strengthened his determination to revenge. Under the guidance of a fellow prisoner who was also falsely accused of imprisonment, Edmond carefully planned his escape and left the infamous Monte Cristo Castle forever. After that, Edmond turned into a mysterious and rich count of Monte Cristo. With his charm, cunning and ruthlessness, he graally mixed into the circle of French nobles and implemented a cruel revenge plan against the guy who once betrayed him step by step http://ke..com/view/440996.htm
the new version of RMB has been issued for some time. Have you ever used it? Anyway, my family went to the bank for a lot of money. They prepared to send red envelopes ring the Spring Festival. The new version of RMB is very suitable for the new year< br />
\<
however, Hao Mingjian, editor in chief of yaowenchuizi, recently pointed out that there are some typos on the new version of RMB at the release site of "2015 top ten catchwords" in yaowenchuizi! Xiaobian, when I heard the news, I quickly took out the new version of RMB and had a look, right< br />
\< According to Hao Mingjian, editor in chief of biting words, the word "Yuan" in the "one hundred yuan" in the new version of RMB is wrong! Although there was "silver dollar" in the past, we only wrote it in RMB, but now it is stipulated that the unit of RMB is "Yuan". It is obviously wrong to write it again< br />
\
I understand all the reasons, but I really want to know why the old version of RMB has been written like this all the time. Why did it start to discuss this issue in the new version? Besides, it's also the "Yuan" on the ten or twenty yuan. It's obvious that holding on to the new version of RMB is to attract people's attention
he is worthy of being the editor in chief of "biting words". He has really "biting words". Not only this time, he pointed out seven grammatical errors on his ID card: "name", "gender" and "address" are juxtaposed with "birth", but "birth" is a verb and should not be used in juxtaposition with three nouns< br />
\
this kind of diction reminds me of the Chinese examination questions in high school. We also work hard every day to pick out language diseases and wrong words, and we will become neurotic. However, when we graate from high school, the wrong usage will be used repeatedly< br />
\
however, with the development of the Internet, there are more and more popular words on the Internet, and most of them have no grammar to speak of. If we all speak according to the rules, the world will become very boring ~
& # 92
it's necessary to pay attention to grammatical errors and typos, but it's also unnecessary to find fault. For example, the new version of RMB can be written as the country likes. Anyway, we have been used to the "one hundred yuan" for a long time< br />
\
however, if anyone dislikes his wrong words in RMB, please send them to me by mail, 10 yuan per kilogram, and collect them at a high price
