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

Just into the mining area, it is recommended not to look for mining software, because most of the mining software, after all, is still more pit, such as pumping problems or more. Ordinary mining software is mainly to configure some of the pool and wallet address, once the configuration error on the white mining, a great risk
I tried all the mining software on the market, and then I chose the mining mode of ha Yu miner + video card miner to mine, and the effect was good! The cost of learning is also very low
3. Power generation is the use of electricity. There is always a distance from the power station to the electrical equipment, whether long or short
AC can be easily increased or decreased by transformer, so as to realize long-distance transmission, and the rated voltage of electrical equipment with different power can be adjusted. This is an advantage of AC. power line can be connected with electrical equipment to realize power transmission. But wire resistance, current through heating, this heat is useless, nothing is wasted. In the transmission of electric energy, how to rece the energy loss is studied, so as to effectively use the power resistance
line, now it's me, so the power line loss is p = the total length of I2R line. Design L, the cross-sectional area s of the conctor, knowing that the starting resistance R = P L / s
the actual transmission power method, considering various factors, selects cross transmission voltage and conctor cross-sectional area according to different situations. Large generators proce voltages of 1500 V, 13800 V, 15750 V and 18000 V, which cannot be transmitted directly. In the power station, step-up transformer is needed to boost the power supply, and then it is transmitted to the remote. China's long-distance transmission uses voltage of 110000V, 220000v and 33000v, and voltage supply of 500000 V has been adopted in some areas. The highest test transmission voltage in the world is now 1.15 million volts. Voltage
long distance transmission is very high, and the direct application of electrical equipment, so the power area, as you said, according to different users, establish county-level substation, such as 220kV, 110KV, 35kV, 10kV substation, rece the voltage step by step, and the voltage drops to 10000 V, and send it to the power station that needs high voltage, and the voltage drops to low voltage of 220 / 380 V, for general users, such as families Schools, shops, organs, enterprises and institutions
with the construction and development of urban and rural areas, the distribution network for China's power consumption is increasing rapidly, and the task of 10kV power supply is becoming more and more important. In order to ensure 10kV power supply and distribution network with increased safety, economic and reliable operation, China has launched a matching power planning and practical design experience, For example, the design code of power supply system and technical specification for design of 10kV substation and 66kV and below overhead power lines, design specification for overhead distribution lines, design specification for insulation on overhead distribution lines, design specification for power engineering, 3 ~ 110kV High voltage cables, are included in the design code for rural power network planning and design as urban power grid planning and design guide and urban planning standard Code for design of power distribution devices "code for design of relay protection and automatic devices", "code for design of electrical measurement and energy metering devices" and "Atlas 10kV and below power distribution line project" Atlas 10kV and below power distribution equipment project "of" 10kV and below atlas ". Friends who are interested in consulting county power professionals can also borrow books from them.

With the development of society, our life is getting better and better, and our way of life has changed a lot. Now we have digital RMB. What is the significance of accelerating digital RMB? In my opinion, first, it can facilitate people's lives. Second, it can rece some unnecessary economic losses. In addition, it can track the flow of funds and prevent some crimes. Next, I'll give you a specific explanation
Digital RMB can also stop crime. Although our society is very harmonious now, there are some criminal acts behind it, such as swindlers or other criminal acts. However, with digital RMB, we can track the whereabouts of the money, so as to catch these criminals and compensate for our money losses. In addition, in the era of digital RMB, some economic crimes, such as manipulating a large number of currencies and manipulating the market, can be found and stopped quickly. To sum up, with the development of society, our life is more and more convenient. By implementing digital RMB, we can make our life more convenient, make our travel more convenient and avoid some losses. In addition, we can also rece unnecessary economic losses, such as some economic crimes, and find and stop them in time through digital RMB, so as to maintain social harmony and avoid major economic losses5.
