How often does local prospecting and mining take place
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. In other words, the difficulty of digging bitcoin is increasing, while the time required is increasing
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

Recently, the price of bitcoin continued to rise, reaching a maximum of US $41000. According to Mr. Liu, the manager of the mine, recently some customers have asked for additional orders, but the output of the mining machinery manufacturers is insufficient and they can't get a large number of mining machinery. Now they have to wait five months or more. Most of his customers have increased their positions in the middle of this year. At present, the prices of mainstream mining machines vary from 30000 to 60000, Mining takes about 12 months to recover the cost
therefore, if people really have mining ideas, they should not be dazzled by the impulse of the moment, and they should try to do it slowly. Today, the price of bitcoin continues to rise, largely because many mainstream investment institutions or investors begin to be interested in digital assets and begin to hoard bitcoin
bitcoin investment has great risks, the phenomenon of sharp rise and fall is not uncommon, and there are not a few people who have lost all their money. Therefore, it is not advisable to follow blindly and keep calm in investment

bitcoin plummeted by more than 10%:
earlier on January 11, bitcoin once fell to $37000 / piece, the lowest to $35141, and the biggest drop in the day was more than 10%. According to the data of bitcoin home.com, the amount of burst positions in the past 24 hours reached US $1.165 billion (about RMB 7.530 billion), and a total of 115138 people burst positions within 24 hours
for the sudden drop, some netizens said: "what should come will come.". Cautious investors said that such a high position, I first clearance, short about
a total of 2100W bitcoins are issued, and each block is generated for 10 minutes, and a block rewards a certain number of bitcoins. In the beginning, 50 bitcoins were awarded for each block of mining. In the future, the reward was halved for every 21000 blocks (about once every four years). Now, 12.5 bitcoins are awarded for each block generated. The generation time of each block is 10 minutes, but with the development of computer technology, now the mining calculation power is increasing, so the generation time of a block must be less than 10 minutes, which requires certain control measures to ensure this time. This measure is the difficulty of mining. If the output time of each block is less than 10 minutes, the difficulty of mining will be increased. If the output time is more than 10 minutes, the difficulty of mining will be reced. The difficulty adjustment time is 2016 blocks, that is, 2 weeks
after every 2016 blocks, all nodes will automatically adjust the mining difficulty according to a certain formula. This formula is obtained by comparing the latest time spent in 2016 blocks in this cycle with the expected time (20160 minutes, i.e. two weeks)
new difficulty = old difficulty * (time spent in the past 2016 blocks / 20160 minutes)
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

Chapter 5: kuangshen is out of the mountain
in the past month, apart from being disturbed by several people who have come to discuss the sharing issue, I've been hanging in the game To put it in here, it's really like eating the same rice and raising a hundred kinds of people. There are all kinds of people. They are either addicted to cleanliness or superior. They tell me before they rent together. Finally, none of them have been discussed. Fortunately, the mining business is going well now, so I'm not in a hurry if there are no suitable people)
"Ding Dong", the pleasant hint of the system rings in my ear again, "Congratulations, the player's" depth "expert level proficiency is full, and all upgrade experience is skill experience, which meets the conditions of upgrading to" mine God ". If you choose to upgrade, the character's attribute points will be adjusted. Do you want to upgrade, please choose?"
dizzy, what's going on? I haven't mentioned it on the home page or the forum. The "miner God" sounds great. It's not bad, but I don't know what's going on with the adjustment of character attribute points. I'm not sure. But forget it. I'm going to this one. I'm sure I'll choose "yes" and get promoted
"Ding", the system prompts "player's" depth "is promoted to the first" mine God ", reputation is + 500, level is promoted to level 16 (explain, I have already practiced to level 15, I could have left the novice village to a better mining area near Xuanyuan City, but the main consideration is efficiency...
it should be what you need
The exploration right is generally three years, and can be extended before the expiration; The term of mining right: the longest term for small, medium and large mines is 10 years, 20 years and 30 years respectively. If there are still minable resources before the expiration of mining right, it can apply for extension. The extension term is determined by dividing the retained resources by the annual mining scale, but the longest term can not exceed the corresponding longest term for small, medium and large mines
