The mine has been recovered due to an unexpected system failure

1. Thank you
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.

Yottachain: blockchain storage has an overwhelming advantage over the existing centralized storage (AWS / alicloud / EMC / Huawei) in the persistent storage market. The data reliability has been improved exponentially. It has excellent anti DDoS and disaster recovery characteristics, and the cost has been reced several times. Taking yottachain as an example, the details are as follows:

(4) when reconstructing the data of a failed node, it will be divided into many nodes to reconstruct at the same time to speed up the reconstruction speed. For example, if a fragment of 10000 files is stored on a failed node, it takes 0.5 seconds on average to rebuild a fragment (mainly for network transmission). 100 nodes are selected to participate in the reconstruction, and each node only needs to rebuild 100 fragments, with an average of 50 seconds to complete the reconstruction. As long as the other 30 nodes of the same file will not fail at the same time within 50 seconds, the file data will not be lost

(5) e to good rendancy and scattered geographical location, there is no need to worry about hard disk damage, operation and maintenance failure of indivial nodes (Tencent cloud lost user data e to operation and maintenance failure in August 2018), lightning weather (in September 2018, Microsoft's azure service in some areas was shut down for more than 20 hours e to lightning), power failure, optical fiber being cut off Data failure is caused by earthquake, fire and other reasons

(6) because the nodes are scattered and rendant, they are not afraid of DDoS attacks

3. Level 10 is about 3-8 minutes in North County! After level 10, go to chaogeshan to form a team and brush to level 20 for 1-2 hours! After level 20, go to Nanjun or Congyu and form a team to make a ghost . Once you open a pair, you can upgrade to level 1-2, 1-2 hours to level 25! After level 25, you can get 2 white jades and 2 green jades by applying for character code, and you can get a white jade for millions of money! 3 white jade can be about 31-32! After 30 can do Nu Wa, Qingyuan mission only do 4 or 5 stars! Receive reward task, send jade or eat Dan! 42-47. At this time, you have learned to fight. At this time, you have been really liberated. The news line of brush autumn maple. Because of the strange meeting, people will run. 47-55. Ninghai's left behind is a golden point. But there are many people, It's a waste of time. Brush when nobody's around. Brush the Jingwei of autumn wind when someone's around. When it's 55, we'll start receiving announcements. We can't miss 5 hours a day. It's very cool. 55-60. Go to Huangsha. It's a golden point. Follow the previous method, At this time, you must be one of the top 5 fighters. Huangsha is the world of dark teams. Heroes don't suffer losses. Let's go into the cave and brush. 60-67 days. (plus three Nuwa) 60-67. Fu upper layer. 2 days to 67.67-73 (the first spring). General platform, super golden point, there are 66,67 monsters. Brush to 70 to save experience. Time 1 day 2 nights. 73-76, Time is one day. 76-83 (the second spring) practice 3. The same golden point. Time is two days. After level 80, you can get five quick acting topaz by binding your character with a computer. Plus one million yuan, you can get six Topaz experience of 6 million yuan! 83-91 (the third spring) Chishui City. The land of kings. All the kings of China made their fortune here. The most advanced team in Chishui is No.1. I have calculated that the average time in Chishui is 4 hours. It takes 5 days to stay in Chishui. 91-94. Tianzun cave. A place of high experience. 2 days. 94-97. 2 hours FM every day, and then go back to Tianzun cave to brush. 2 days. 97-100. You can go to the sea to brush. You can also brush in Chishui. 2 days. 101-120, Every day to do Kunlun 2 million or so experience, Qingyuan 4-5 mission 3 million or so experience, Nvwa more than 40 clearance! 3 times 4-5 million experience! This is about 10 million experience per day on average!!!! The system will send you a statue at the first level of a new born person. You can directly click to answer the questions (select all C). When you have answered all the questions, it will be level 2, and then go to pick up & lt; Meet the mayor & gt& lt; Recruits report & gt& lt; Refiners & gt; After the completion of these three tasks, you will reach level 4, and then go to the quartermaster to take over the task, the alchemist to take over the task, and the blacksmith to take over the task. After the completion of these three tasks, you will reach level 6 or more. Now you can finish all the single line tasks according to the system, It took less than 20 minutes... Now you don't have to do those trivial tasks at level 10. Go straight to level 1 of the pilgrimage song of tianshengyuan to kill monsters. As soon as you walk in the door, you will have a green suit. You can brush the task infinitely if you click it. Start to accumulate experience at level 18. (if no one grabs monsters, 40 minutes is enough) when you save it, go directly to the inside to brush the ritual corner. It's jingyingguai, It's a little hard to play, but the experience is good. You can practice all the way to level 25 and accumulate experience to level 25. Ha ha, at that time, your spring is coming again. If you have QD friends who buy 5 white jade hair and finish it directly at level 31, those who don't have money go to pick up the white jade task and complete more than 2W experience at a time, remember to accumulate experience at each stage, because different levels play strange, If you want to upgrade quickly, you have to praise your experience. 25 and 28 are two stages. It's easy to play a strange game. When you save 31, it's time for you to make money. At this time, you can go to brush 2 tasks with both money and experience until 34, and then pick up the token task until 37. If there is no accident, this stage should be all in Xuanyuan, A few friends on the group upgrade that speed basically did not say

4. This is a common driver drop, which is related to the quality of the graphics card itself and the newer driver.
at present, what you can do is to get an old driver, unload the new driver and install the old one.

5. If it occurs frequently, the graphics card driver is generally incompatible with the system,

the computer graphics card driver must use the driver provided by the computer official website, and must not install the driver downloaded from other places

The harm of computer not shutting down for a long time is as follows:

1. The service life of computer hardware is reced

computer hardware has a service life. The higher the frequency of use, the greater the probability of failure. Generally, the probability of CPU and memory failure is small, but the probability of failure of motherboard and hard disk is large

2. Long time high temperature has great damage to the computer

keeping the computer on for 24 hours and being in a high temperature state for a long time has great damage to the computer hardware, related components and components. High temperature can be said to be the biggest killer of computers. Many failures are related to high temperature, so we must deal with the heat dissipation problem after long-term use

3, waste of electricity

even if the computer is on standby, it will also consume electricity. If it is not turned off for a long time, it will waste a lot of electricity, and turning off is concive to saving electricity

< H2 > extended data:

the harm of frequent switch on and off:

frequent switch on and off will damage the life of the computer, and the hard disk and display will suffer

when the hard disk is out of service, the read-write head is next to the disk surface. The buoyancy generated by high-speed operation after power on makes the head float above the disk to work. After power off, the read-write head returns to its original position, which naturally increases the wear of the disk

when the monitor works normally, its current is relatively stable. When the monitor is switched on and off, the sudden increase and decrease of current will cause a certain impact on the monitor, so frequent switching on and off is naturally unfavorable to it

many components in personal computers are not designed to run for a long time. Long term startup not only costs electricity, but also consumes the life of computer hardware. For example, if the hard disk is not shut down for a long time, the service life of the hard disk will be dramatically reced. If you don't turn off the computer for a long time, the st in the computer will accumulate quickly. Too much st will adhere to the surface of CPU, chip and fan, which will lead to poor heat dissipation or poor contact, and rece the service life

computers running for a long time are easy to accumulate all kinds of junk files, which will also affect the efficiency of computers. Therefore, experts suggest that if the computer is not used for more than 3 hours, it is best to turn it off

In addition, the PS / 2 interface mouse, keyboard and various serial and parallel port devices can be plugged in and out without power off. These are seemingly common, but very dangerous operations, which may cause abnormal operation of the system or hardware, or damage of the hardware interface or motherboard

in addition to USB, IEEE1394 interface and serial port hard disk, all kinds of peripherals of ordinary desktop can't be hot swapped, so don't be afraid of trouble when doing other hardware operation, be sure to do the correct operation in the case of power off to avoid unnecessary loss
