If mining is really that simple, then many mines will not be located in the deep mountains and forests near the power plant. Every mining machine with amazing computing power and high value in the mine consumes a lot of electricity, which can be described as a tiger eating electricity.
At present, the computing power of a professional mining machine has reached an astonishing 1 10TH/s, with a power of 3250w, which means that it consumes 3.25 kWh per hour.
Such a mining machine with computing power of 1 10TH/s can produce 0.2 158 bitcoins a year and consume 284,700 kWh of electricity a year. If the electricity charge is calculated at 30 cents, it will be 854 10 yuan/year. If you mine for one year according to the normal commercial electricity price, you really can't get your money back.
What is the concept of computing power of 1 10TH/s?
1H/s is one hash collision per second, and 1TH/s is 1000G hash collision per second (1 trillion times), so the computing power of1kloc-0/0th/s is/kloc-0.
Get a colorful GTX 1080Ti Neptune water-cooled graphics card. This graphics card is very explosive for an ordinary computer. After overclocking, the computing power is about 1.8 ghh/s, which is 0.00 18th/s, and digging a bitcoin at this speed can be described as year, month and day. It is better to wash and sleep, not to mention using an ordinary home computer to dig bitcoin.
It is still possible to mine with a home computer before 20 10. 20 10 it takes 7.3 million hash collisions to dig a bitcoin, which is 7.3 million hash collisions. At that time, if you knew how to mine, it was still possible to dig out bitcoin with an ordinary computer. However, at that time, the price of bitcoin was not attractive enough for ordinary people, just as everyone regretted why they didn't buy a house earlier.
Since 20 16, the price of bitcoin has been rising with the difficulty coefficient of mining, giving people the illusion that the price of bitcoin has increased with the improvement of computing power. In fact, if we carefully observe the calculation curve and the price curve, we will find that the price is not directly proportional to the calculation power, and both the price and the calculation power rise and fall with the passage of time. At this time, we will find that it has the market attributes of stocks, bonds and futures, can be hyped, and will also be affected by factors such as markets and policies.
According to Satoshi Nakamoto's algorithm, the total number of bitcoins is about 265,438+0 million. At the beginning, 50 bitcoins will be rewarded for each bookkeeping, but the reward will be halved every four years. It is estimated that the 2 140 reward will become zero, so the harder it is to dig bitcoin.
So it seems that Bitcoin is a scarce resource, but it has no monetary attribute, just a string of useless strings. It's just that these people in the currency circle are pushing it up, and a rising tide lifts all boats. If one day this huge bubble bursts, bitcoin is a string of characters, and the person who takes it is the one who can't take it out.
What the hell is Bitcoin? Bitcoin is an incentive mechanism to maintain the blockchain accounting system. For the whole blockchain accounting system, the more people involved in mining, the more people involved in confirming the general ledger data, and the safer the block data. If there is no such incentive mechanism, the blockchain accounting system will not play a role.
Every node in the blockchain has bookkeeping rights, but the bookkeeping rights of each bill are obtained by connecting a math problem, but this math problem is very difficult and more and more difficult. Whoever works out the value within the difficulty coefficient first has the priority of bookkeeping. After the calculated value is verified, it is packaged with the account book and broadcast to the blockchain, so as to complete the accounting process and then receive the corresponding bitcoin reward.
Come to think of it, it's really lonely to dig bitcoin. The mining machines in so many mines consume so much electricity every year, just to understand one math problem after another and get the bookkeeping right of bitcoin transactions. Is this electricity used as a factory to produce incense? Even if it is used to blow air conditioning, it is worth it.
Bitcoin is surrounded by capital, and then when the high level is close to collapse, the capital will be withdrawn. Will it be another chicken feather and a mourning? Therefore, ordinary people should not use their notebooks to dig bitcoin.
How many notebooks do you dig a day? Are you here to be funny? Bitcoin mining machine is also called high frequency computer. Why is it called a high-frequency computer? Because its computing speed is measured in t, it took a year for a 1 1.5T mining machine to dig a bitcoin three years ago. 1T= 1024G, the period of bitcoin digging madness is decreasing, that is, the longer it takes to dig a bitcoin with the same computing power.
How many bitcoins do you have to dig in a day? Maybe you can imagine whether you can dig up 0. 1 bitcoin a year.
According to the popular saying, ordinary computers generally can't get their electricity bills back. Although the notebook belongs to the company, you can pay the electricity bill at home by yourself. Therefore, mining with a notebook with reduced performance will definitely make you very happy on the electricity bill.
Pies don't suddenly fall from the sky.
Bitcoin broke through $56,000 on the morning of February 20th. By 13:30, the price of bitcoin was about $55,624, rising by 8.29% within 24 hours. Within 24 hours, the turnover was $753.9, with a market value of 1.04 trillion, and it entered the "trillion club".
The above data certainly looks attractive. A bitcoin is worth nearly 400,000 RMB, which is the salary of many ordinary office workers who have worked for six or seven years without eating or drinking. If they want to use their laptops to mine at home, it is estimated that they can't even earn electricity.
Get rich overnight, just think about it and keep your feet on the ground.
Bitcoin's current computing power is difficult to remain unchanged. Even if you use the current 3060 graphics card to dig bitcoin, it will take 1400 years to dig a bitcoin. So don't have any substantive illusions. Your contact time with Bitcoin is now 202 1 year, not that time node in 2009.
Bitcoin has risen from the initial few cents to the current maximum of $58,000. In other words, the price of Bitcoin was only a few yuan around 2009, but it has now risen to 300,000 yuan. Coupled with the borderless and decentralized nature of Bitcoin, the computing power of Bitcoin has increased exponentially in the past 1 1 year, and there are professional mines of Bitcoin in areas with rich and stable electricity all over the world.
So at present, any of our more advanced home computers can't directly mine bitcoin. Otherwise, why can you hear professional bitcoin mines and corresponding mining machines? At present, hundreds of professional mining machines consisting of thousands of graphics cards are concentrated, contributing computing power to Bitcoin. Whoever packages the corresponding box first will get a 6.25 bitcoin reward.
The times have developed to this stage. If it is now the time node of 2009 or even 20 10, then the home computer can really support bitcoin mining, and the computing power of the whole network is not high, and the participation is very small, because many people didn't understand Bitcoin at that time, and Bitcoin at that time was worthless.
So we can see that in the first half of 20 10, some miners sold the corresponding bitcoins on Taobao, and the prices at that time ranged from 5 yuan RMB to 10 RMB. Even in the second half of 20 1 1, the price of bitcoin at that time was only about 60 yuan RMB.
However, since the second half of 20 12, the development stage of Bitcoin has basically passed the era of calling computers to contribute computing power and began to enter the era of professional mining machines. Of course, the current price of Bitcoin has a rich profit return rate for the corresponding mining, but in the bear market of Bitcoin, mining is basically at a loss. At that time, only by saving money and waiting for the bull market cycle can we get the total profit.
So don't easily participate in the professional bitcoin mining industry now. The entry threshold of this industry is extremely high, which requires professional personnel and great capital chain support, and the risks are relatively high.
How many do you dig a day? At present, the price of bitcoin is nearly 50,000 US dollars. Others put dozens or hundreds of graphics cards in the room and use shelves to mine. At the speed of laptop mining and decoding, it is estimated that no one has been there for several years. If you want to mine, you must have at least 1050ti graphics card. Moreover, the more graphics cards, the faster decoding, and the life consumption of electricity and graphics cards is not small. As an ordinary person, it is best not to play bitcoin.
Do you believe that pies will fall from the sky? Even if you can dig it, you need a strong server lineup, not a small computer of yours. Moreover, digging one is not calculated by day, but by year. Do the math, can you dig one a year?
Wake up, big brother. Your idea is easily deceived.
The psychology of getting something for nothing is too heavy, and the behavior of blindly following the trend is also heavy. At best, it is unrealistic.
Let's keep our feet on the ground.
4000 3kW mining machines can dig out a BTC 24 hours a day, and your 20 notebooks are not as powerful as a mining machine. According to this calculation, it takes 80,000 days for a notebook to dig out a coin, and an average of 80,000 bitcoins can be dug up in 24 hours.
However, even if you dig a notebook for 80,000 /365=220 years, you will never dig a bitcoin, because every two years or so, the number of coins hidden in the blockchain will be halved. According to this logic, even if you dig this notebook for ten thousand years, you can't dig a bitcoin [covering your face] [covering your face].
Dude, you think too much. I don't know if you have watched the news. During the epidemic, many Internet cafes in South Korea were closed for mining, and computers in the whole Internet cafe could not be dug much in a day, let alone notebooks. I have a friend who specializes in mining. He built a mine on the border between China and Myanmar in Yunnan. Because the electricity bill there is cheap. In the past, many people in Inner Mongolia built mines because they were all stolen, and they were later arrested and sentenced. So we are not people who can't operate basically in the circle. It is better to send more articles to earn some pocket money!
