How long can the home bitcoin digger graphics card last

1.

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

Why use graphics card to mine

compared with CPU, GPU is used for general purpose calculation. So it can stack hundreds of stream processors awesome. Each stream processor is like a small CPU. Although its ability to run complex programs is far from the power of CPU, it can not support many processors, so the actual performance, especially the single precision floating point performance is much stronger than that of CPU. p> However, as we have mentioned before, a card is very suitable for general computing such as virtual currency because it has many stream processors, and the speed of obtaining specific solutions is much higher than that of N card. Therefore, many miners rush to buy a card to calculate virtual currency for profit

of course, with NVIDIA's Pascal graphics card, n card's ability in mining virtual currency is not as different as a card before. So in the current situation that a card is generally out of stock, those mid-range N cards have become the second choice for miners

What are the disadvantages of mine card

finally, I want to talk about why we can't choose mine card when we are shopping for second-hand cards. Because the miners are mining bitcoin, the most important thing is to seek profits. Therefore, the graphics card they use is running and calculating all the time, and its strength is far greater than that of daily game applications. In other words, running such a calculation for one day is equivalent to running a graphics card for one month

in addition, the places where virtual currency is mined are mostly the places where multiple graphics cards gather. Thousands of graphics cards are constantly calculating in a room, and their heat is also quite huge. Miners can not choose the chassis with good heat dissipation conditions like ordinary consumers, so that the heat can be released smoothly. In this way, the graphics cards can still operate for 7 * 24 hours under high temperature conditions, It also deepens its aging degree

the result of doing so is that the graphics cards used for mining are lost prematurely. If you buy these graphics cards, the result will be unstable operation, restart and other things will continue to happen

moreover, at present, manufacturers also have strict requirements on mine cards, such as banning second-hand sales and shortening the shelf life. If users buy these mine card graphics cards, future maintenance will also be a big challenge

3. If you are poisoned or your hardware is damaged, I advise you not to use your home computer to mine. My gtx780 is afraid to mine. If you set up an ordinary graphics card with a computing power of 200mh / s and a full load computing power of 150W, you will lose 1.49 yuan in 24 hours and 44.79 yuan in a month. If you add in the cost of a graphics card of thousands of yuan, it's even worse.

4. As long as it is a regular digital currency, there is an electronic wallet to download

for example, bitcoin, lightcoin, gold card, reborn coin, doggy coin, lightcoin, Ruitai coin, bitstock and other digital currencies can be downloaded from rich packages
but there is no wallet to download MLM or some direct selling coins
for example: Baichuan coin, Morgan coin, treasure coin, etc.

5. The actions in bitcoin can be regarded as the use of graphics card to do continuous general computing, and the computational complexity is relatively low and quite repetitive. The stream processor used by graphics card is just suitable for such an algorithm. It's like constantly solving equations. The graphics card is 2000 middle school students, while the CPU is 8 math doctors. Although the mathematical knowledge of the doctor of mathematics is far more than that of the middle school students, the speed of solving medium-sized equations such as virtual currency is certainly not as fast as that of 2000 middle school students. Therefore, the more graphics cards, the more operations.

6. If you mean that the motherboard integrates graphics cards to dig bitcoin, first of all, you can theoretically dig bitcoin. Second, considering comprehensively, your input and output are negative. That is to say, if you invest 2000 yuan (motherboard, CPU, electricity), you get 10 yuan bitcoin
if you just want to practice the use of mining software, you can. If you want to make a profit, you can't.

7. Hello, you can't find bitcoin. Maybe two years ago, but now you get nothing but waste electricity. Mining has become a very professional thing, ordinary computer mining, graphics card mining has long been eliminated. Now mining needs professional ASIC mining machine, even so, the profit margin of mining is very small. At present, retail investors have graally launched the historical stage of mining. Now mining relies on low electricity price and low energy consumption mining machine.

Speaking of the bitcoin market, it seems that it has fallen into a crazy state. We know that the rarity of things is the most expensive. Now there are only 21 million bitcoins in the world, and even one bitcoin has been fried to 150000. It's incredible. In the early days, bitcoin was also regarded as a fraud, and economists were critical of bitcoin. Some economists believe that we should regulate the market economy and use relevant monetary policies, which requires us to have enough flexible money to control the stability of the market. Another part of economists think that the total amount of money should be fixed, recing government intervention in the market, whether it is market expansion or contraction, is a sign of social progress

in fact, for bitcoin, the biggest technology content is blockchain technology, which is also a very important technology, but this importance has not been highlighted yet. In fact, blockchain technology is a set of technology that must be used in every country and instry to realize intelligent and efficient management. However, bitcoin also has some hidden dangers, that is, it challenges the function of the world's major central banks to issue currency. If bitcoin becomes the mainstream currency, it will directly challenge the mainstream currency. Of course, because of this, both the western world and China are opposed to bitcoin. After all, if bitcoin really overflows, it will have a certain impact on society, and even it will be used by criminals

After surpassing the peak in 2017 and breaking the $20000 mark, bitcoin has not stopped soaring. Bitstamp market shows that bitcoin has broken through the $34000 mark, a new record high

you know, as early as 2010, a programmer in the United States exchanged 10000 bitcoins for a $25 pizza. Now, a bitcoin has risen to a high price of 220000 yuan

Therefore, the author suggests that ordinary people who want to take the opportunity to invest should not invest too much. After all, bitcoin's sharp rise and fall is normal, so the investment risk is high, so we need to be cautious when entering the market
