BCD coin mining graphics card computing power

1.

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

2.

You can't dig in a day. It takes 2000 years

the global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin

in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned

extended data:

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

bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer

when bitcoin was born in 2009, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25

when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million

3. Now bitcoin's listing is blocked!!! You still dig, you go to the internet post bar, bitcoin bar, take a look

4. The use of high-end amd graphics card, but the era of graphics card mining has come to an end, has entered the era of ASIC mining. Now, bitcoin can't be found with graphics card, because the computing power is growing too fast, and the difficulty of mining has exceeded 40p. At present, even the professional ASIC mining machine is difficult to profit, because the chip update speed is too fast. The first generation ASIC miner's chip basically adopts 130nm process, the second generation adopts 55nm process, and the third generation adopts 28nm process. But at present, there are not many 28nm mining machines, and most manufacturers just regard it as a slogan, and the high performance of the chip does not represent the overall high performance of the mining machine. Avalon delivered the world's first ASIC miner. The computing power of the second generation chips once accounted for one third of the total network computing power. At present, the third generation chips have been released.

5. There's a mistake upstairs. Bitcoin came out in 2009. How could bitcoin mining machine be 7 or 8 years old

now, of course, there are still people mining. There are about 21 million bitcoins in total. At present, there are about 13 million bitcoins in the world, and there are 8 million left. However, now mining is basically large-scale integrated mining machine, and the era of graphics card mining ended at the end of last year, because with more and more bitcoin being g out, the difficulty of mining is increasing automatically, and large-scale mining equipment is manufactured in batches, resulting in that the computing power of graphics card can no longer generate positive benefits
for example, the current mining difficulty is 16818461371, and the computing power of a better graphics card such as ati5970 is 800mhash / s. It takes 2863 years to dig out a bitcoin. The computing power of the large-scale integrated miner can reach 2tash / s, and it will take more than a year to dig out a bitcoin. There are many manufacturers procing this kind of large mining machine all over the world, and the computing power is still improving. Only this kind of equipment has been put into use for more than 100000.

6.

Mining, in fact, is to use graphics card to dig bitcoin. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million

bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items

7. Pro, are you going to get rich or interested in mining? If I'm interested, I won't say anything. If I want to get rich, I'll advise you. Forget it. It's not worth it. Now mining is a loss business

8. Any computer can operate, just a professional miner, a day may top your computer work for a month or even longer

9. See funny pictures can go to Jun Bujian to see there are a lot of funny pictures funny jokes, hope to help you
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
the source is not cheap
