How long can the ether coin mine last
The most advanced bitcoin mining machine, one to two years to dig out a bitcoin, bitcoin mining is now too difficult. If you want to dig, you can dig ether currency. Now it is steadily appreciating every day. According to the current development trend, it will be able to recover its capital in about seven months, and then it will be profitable< br />
the answer is yes. Bitcoin does not have a centralized issuer, but is generated by the calculation of network nodes. Anyone may participate in the proction of bitcoin. But bitcoin is not issued in unlimited quantity. According to calculation, by 2140, the total amount of bitcoin will reach the upper limit - 21 million. Recently, according to the data from blockchain.info, unless there is an accident, the 17 millionth bitcoin is likely to be g up in the future
it needs to be clear that each newly g out bitcoin block will generate 12.5 new bitcoins, and a new block will appear in the bitcoin blockchain every 10 minutes, so about 1800 new bitcoins will be generated every day. As the reward is reced by half for every 210000 blocks generated, mining becomes more and more difficult, but this does not mean that bitcoin mining machines can no longer dig bitcoin. In addition, it needs to be made clear that bitcoin will not stop running when it proces 21 million bitcoins, so even if the 1700th bitcoin will be g out, there are still 4 million bitcoins waiting to be g out. Even if it is more and more difficult to dig out bitcoin, it is not impossible. It is said that the new routing machine that originally g out digital gold will also launch the function of digging bitcoin in the near future. Compared with thousands of professional bitcoin mining machines, the new routing machine is more user-friendly in price and less difficult in mining
in the future, we believe that although bitcoin has gone a long way, bitcoin still has a long way to go.
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
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

politics and English: 50 points. Last year, the first and second districts of the country began to merge, and the score line of these two subjects is unlikely to rise this year. English line is the most concerned problem of many economic examinees. The highest score of this subject in history is 55 points, which appeared in the 11 year postgraate entrance examination. It is very difficult for the line of District 1 to exceed the peak. After all, we have to consider the students of the former District 2. If the national line is set too high, there will be a problem: fewer people can cross the line, which will make many schools dissatisfied with the enrollment. Therefore, I estimate that the score of these two subjects is still 50
Mathematics (professional course 1) + professional course 2:90. In fact, it is not necessary to estimate these two. Basically, these two subjects can't pass the national line or their scores are low, so it's very sad to be in the national line
total score: 335-345. 2011 is a historical peak, 350 points. Last year (2012) was 340. This score is the score line of District 2 in 2011. Therefore, the score may rise this year. We are still considering the situation of the former two districts. Even if the score rises this year, it will not be too high. So the upper limit of 345 comes from this. The lower limit? Because there is a high score base of the original district (i.e. Beijing, Shanghai, Guangzhou, etc.), the decline will not be too much
the above are my predicted scores and predicted results
P.S. I am now a graate student and took the exam last year
it's OK in the first two seasons, but not in the third
the second season is as shown in the picture. It's a 1080p version. I wonder if you can save it
There are only 8 episodes in the third season, which can be cached for you if you want. But you have to keep it in time< br />2. You can enter the safe mode of the computer, that is, restart the computer and press F8 to enter
3. In the safe mode, you can use the virus of the computer manager to check and kill the computer virus.
