Compared with the original currency graphics card mining

1.

The miner is better

1. the electricity charge for mining with graphics card is very high, and the performance is not high, so it can't even earn the electricity charge

2. mining is an investment more than time and speed. We should try to dig more money in the shortest time. Therefore, the professional mining machines of BTC now stress the characteristics of simple operation, small footprint and low power consumption. For example, Yingtai has developed a professional mining motherboard with a computing power of 23.488g/hash, and the proct model is btc-24gh< br />

2. Before the appearance of mining machine in 2012, the era of mining with graphics card used a card, because mining is to split hash operation into multiple sub operations. At that time, a card can complete one operation with one instruction set, while n card needs three instruction sets to complete one operation. Therefore, the actual operation efficiency of a card is more than twice that of N card, which is close to three times

in fact, n card has greatly enhanced the mining efficiency in the Maxwell architecture, not inferior to a card. But the Maxwell architecture came out too late. When the earliest Maxwell architecture graphics card, such as gtx750ti / 750, came into the market (early 2014), the mainstream currencies could not dig out anything with graphics cards (all mining machines). Therefore, few people use n-card mining.

3. bitcoin is a member of the virtual currency. The data is calculated by a specific algorithm, and the total number of data is fixed. Therefore, bitcoin is less and less g, and it is more and more difficult to dig. Recently, bitcoin's rise is quite high, which has spawned a group of new miners to enter the pit. It can only be said that they are waiting for the mine disaster. Amd graphics card is generally preferred in mining, because in recent generations, n card tends to simplify the basic floating-point operation and improve the utilization rate of the architecture to the core, while a card has always liked the heap stream processor with crazy heap parameters, just what mining needs is the basic double precision floating-point operation ability, so a card is generally preferred in mining.

4. Our country is against digital currency.

5. Bitcoin is a distributed virtual currency without a central bank. The real value of this kind of currency depends on people's degree of speculation. If there are more speculators, it is very valuable. If there are fewer speculators, it can be said that it is penniless
brother, have you fried the futures trading category, how is it going? If you haven't even fired the futures, it's best not to mention it. To tell the truth, this is a virtual bubble. It's hot now, but once it is gone, it will be penniless.

6. Guiminer software needs graphics card to support OpenCL. You can use gpu-z detection software to check whether your graphics card supports OpenCL. If it supports OpenCL, you will check the small box in front of OpenCL at the bottom of the detection page. If it doesn't, it won't be supported. There is also a newer version of the graphics driver. I don't know if that's the reason. I hope I can help you.

7. The so-called "mine" is virtual currency. There are many kinds of virtual currencies, among which bitcoin is the most famous. The concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. Point to point transmission means a decentralized payment system. Unlike most currencies, bitcoin does not rely on a specific monetary institution to issue, it is based on a specific algorithm, through a large number of calculations. 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 money circulation
GPU is used for general purpose computing. 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. 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.

9. How to break the inherent defect mode when opening a nutritious breakfast shop? This requires operators to improve their procts, methods and environment. The following winning skills can be used for reference< According to statistics, of the 21000 catering outlets in the city, there are only about 3000 outlets operating breakfast, with few truly reassuring and distinctive breakfast outlets. Since some low-end restaurants and street market stalls are the main force in providing breakfast in our city, we should give priority to the hygienic conditions and dining environment that consumers attach most importance to
therefore, if the economic capacity permits, the facilities should not be simple and crude, and should meet the food hygiene standards. Convenient, fast, healthy and high-quality breakfast is the most expected< Second, pay attention to the diversification of characteristics
according to the reporter's investigation and interview, there are few varieties and colors of breakfast in our city, so it is difficult for diners to choose according to their own taste. Almost all kinds of "juice, fruit, bean curd, steamed stuffed bun, porridge, fried cake" have remained unchanged for decades. Due to monotonous operation, lack of innovation and proper variety adjustment, it can not meet the public's requirements for diversified breakfast varieties and different tastes. Therefore, it is the most important task for operators to develop new breakfast varieties with health, nutrition and hygiene< Some famous traditional breakfast shops can be renovated in time, and the dining environment can be comprehensively transformed to absorb the operation mode of Western fast food. After the transformation, the shops have advanced facilities and will attract more customers with a new look. In addition, we should constantly innovate in business varieties and service opportunities. Only with standardized operation and management, comfortable environment, reasonable price and considerate service can we win the favor of the public< Fourthly, chain operation should give full play to its advantages.
it is very beneficial to actively introce advanced new business forms and promote chain operation of breakfast market for expanding the scale of breakfast market, improving the organization degree of breakfast market, recing proction costs, forming scale effect and improving the circulation speed of breakfast food. It can give full play to the advantages of chain operation in organization mode and management, widely use advanced proction equipment and technology, actively develop new varieties of modern breakfast, improve service level, and speed up the construction of modern breakfast supply system< Five, the use of modern network technology
conditional breakfast business enterprises should make full use of modern technology, through the efficient and smooth information network, release the information of variety, service price and service mode, and carry out the service of telephone ordering and home delivery to meet the personalized consumption demand
comments: To sum up the skills of operating breakfast shop mentioned above is a close-up of my friends' experience in opening breakfast shop for many years. I hope it will be helpful to you
