1060 bitcoin 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

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

3. Using gtx1060 graphics card to run specific software to get bitcoin is called mining.

4. There are two models of gtx1060. Take the fine gtx1060 as an example, there are two kinds of graphics cards: gtx1060 3G and gtx1060 6G. The core codes of these two kinds of graphics cards are not the same except for the video memory. So the performance and computing power are also very different. Other brands, such as Qicaihong, have broken down many models and given several names e to different video memory, frequency or appearance. However, the biggest difference is only one 3G and one 6G
because this gtx1060 has good computing power, many players use it to dig virtual currency. It's hard to say how many days to return to the original. For example, when a six piece gtx1060 3G machine was at the top of bitcoin, someone calculated that it could earn about 500 yuan a day, but the price was fluctuating at any time, so it was impossible to predict accurately
in a word, mining is risky and investment needs to be cautious.

5. It can be
but the efficiency is not high. Mining is using a card, such as rx480
rx580 graphics card. Because there are thousands of stream processors in this kind of graphics card. The efficiency is also relatively high

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

7. Such a set of mainframe is about 5000 yuan. The main board with 8g memory is 128G solid state and 1t mechanical hard disk
the performance of these two CPUs is almost the same. If the price difference is more than 200 yuan, choose 6500; if it is less than 7500, choose 7500.

8. Bitcoin is very slow and has a certain amount. Generally, it's a professional miner's fee, electricity fee and computer fee. It's better to dream when you are young

"Negative interest rate era" refers to the period when the price index (CPI) rises rapidly, resulting in the negative interest rate of bank deposits. Since the CPI reached 2.7% in February 2010, China has entered the era of negative interest rate. In March 2012, the National Bureau of Statistics said that China's CPI rose 3.2% year on year in February, ending the "era of negative interest rates" that lasted for two years

the so-called negative interest rate means that in some economic situations, the deposit interest rate (usually the interest rate of one-year fixed deposit) is less than the rise of CPI in the same period. At this time, as time goes on, the purchasing power of residents' bank deposits graally decreases, which seems to be "shrinking", so it is called negative interest rate

countermeasures:

first, actively allocate hedging assets“ Golden age usually refers to economic prosperity, rapid growth of residents' wealth, and large space for antique speculation. In the period of economic depression, all walks of life are deleveraging, and gold is undoubtedly the preferred target of residents' risk aversion assets. At the same time, treasury bond assets of safe haven currencies such as US dollar and Swiss Franc can also become the choice of ordinary families. Residents can indirectly hold overseas safe haven assets by investing in QDII, which is the target of low-risk assets of diversified currencies abroad

secondly, leverage should be appropriately increased to increase the real estate holdings in the core areas of second tier cities. At present, the threshold of real estate investment in the first tier cities is too high, and in some core areas of second tier cities with convenient transportation, net inflow of population, complete infrastructure and rent to sell ratio of 1 / 300-1 / 500, the real estate, as the security risk of residents' asset allocation, can also be guaranteed, and the liquidity is also good e to the active transactions in the secondary market. Therefore, the residents can increase the leverage of these areas to effectively resist the erosion of their wealth caused by negative interest rates

finally, we should increase the allocation of insurance assets for our own health, professional ability improvement and children's ecation. At present, major insurance companies have developed insurance procts suitable for middle-income families, such as endowment insurance, serious illness insurance and children's ecation. In the era of negative interest rate, on the premise of ensuring daily expenses, people should hold these insurance procts properly and increase their investment in their own health and children's ecation in case of emergency
