computing power refers to computing power, refers to that in the process of getting bitcoin through "mining", we need to find its corresponding solution M. for any 64 bit hash value, there is no fixed algorithm to find its solution M. we can only rely on computer random hash collisions. How many hash collisions can a mining machine do per second, is the representative of its "computing power". The unit is written as hash / s, which is the so-called proof of work mechanism (POW)
2. At present (2017 / 03 / 23), 1t computing power can dig about 0.00055 bitcoins a day. According to the current currency price, a 1t computing power miner can dig about 4 bitcoins a day. About 0.002 bitcoins can be g in 3.65t1 days, which is about 15 yuan in RMB. However, it is not fixed how much bitcoin can be g every day. Generally speaking, with the continuous upgrading of mining machinery, mining machinery developed by mining machinery manufacturers will continue to be put into the market, and the computing power of the whole network will continue to grow over time. The proportion of your computing power in the computing power of the whole network will graally decrease, and the bitcoin g by the corresponding computing power will also continue to decrease. In addition to purchasing mining machines to build and deploy mines, you can also purchase computing power on computing power platforms such as suanlibao, which can be used as an entrance to understand bitcoin, mining and blockchain. At the same time, you can also have considerable benefits under the condition of accepting risks.
3. Don't believe that there are still things like pie in the sky. If you join in the form of membership, you have to pay es or buy high priced procts. It is in line with the characteristics of pyramid selling to draw high profits from it by pulling people's hair off the line.

5. How to say, I'm just an outsider. I can't say anything. Normally speaking, couples have to face all kinds of difficulties together. It's better to advance and retreat together and resist this difficulty. Of course, if you don't love him that much, it depends on your choice. If you choose to spend time together, you can go to your best ability. Selling houses and cars. And now there's water. It's just my personal suggestion. It depends on you. I wish you happy every day, everything goes well, thank you.

Introction and comparison of proct hardware advantages
1. Quality: from Israel's defense technology, military quality, reliable< 2. Touch technology, simple and fashionable appearance:
(1) touch screen: high strength wear-resistant diamond glass touch sensitive screen, never worn, safe and guaranteed; The common ones are made of acrylic plastic or ordinary fragile glass, with rough appearance, poor handle and poor light transmission performance
(2) sliding cover: independent modeling (not one size fits all) and four axis ball self balancing sliding cover design, comfortable and smooth handle, strong aesthetic feeling. Common is all adopt one size fits all sliding cover design, no ball guide, feel loose, shake or very tight, use up very troublesome
(3) touch keyboard: full screen independent light source, touch sensitive key design, fashionable and gorgeous technology, not rigid. In other brands, all the key lights share a common light source. When they are off, they are all off. There is no aesthetic feeling to speak of
(4) display screen: the first 1.6-inch OLED eye moistening display screen, with humanized configuration design, is simple and clear to operate, and there is no need to worry about not seeing the text on the display screen (especially for the elderly and children). Other brands are not as complicated and inhumane as the display screen, or use 0.9-inch ordinary display screen, the font is very small, the eyes need to be close to the door lock to see, so it is not very convenient to use, especially for the elderly, even if the font is so small near the door lock, it is difficult to see. Moreover, it is even more troublesome to query the door opening record. It takes several screens to display a record, which is really cumbersome
3. System: the main and auxiliary al circuit board al circuit control system, the information verification system and the operation control system are separated, the verification system is outside the door, and the control system is inside the door, so as to ensure the absolute safety of the door lock. Even if the front panel is completely removed, the door can not be opened by connecting the electrical and mechanical source. The ordinary fingerprint lock uses a single system outside the door, it can not guarantee the safety of the door lock
4. Circuit board: IP55 three proofing design: waterproof, moisture-proof, st-proof, installed in the villa, rain is still open, and like in the northern sauna days and the southern return days, as well as the humid environment of coastal cities, there are no problems. And many other ordinary locks do not do this three proofing process will certainly have problems
5. Chip: it adopts the top processing chip of Ti in the United States, with fast and sensitive response speed. In order to carry out wechat networking, it must have very high requirements on the chip, otherwise it will not be able to pass in terms of speed and power consumption. The others are domestic or imported chips, because they are ordinary stand-alone fingerprint lock
6. Fingerprint head: it adopts the latest technology of dark background fingerprint reader, with fast response and verification speed; 0.5 seconds, to eliminate dry and wet fingers, cold winter in the north also use, adaptability is very strong. As well as the use of imported Swedish living biological semiconctor electrostatic inction fingerprint reader, to eliminate false fingers. Others, especially the low-end ones, also use relatively primitive bright background acquisition heads, including Samsung. However, it is very difficult to open the door in cold winter or the fingerprints of the elderly
7. Mechanical key and lock bladder: Super B emergency mechanical key with four side blades, true insert lock bladder, anti technology and tin foil opening, safe and reliable. Ordinary fingerprint lock with a lot of B-class false core lock, technology and tin open door can not prevent, not very safe
8. Panel handle: it is made of Australian No.5 zinc magnesium alloy by 300 ton die casting, never recycled material, no sand hole, no impurity, no water mark, etc., so it is firm and rable. Ordinary locks are made of ordinary zinc alloy materials, and some of them are recycled materials, which will cause rough surface and sand holes, directly affect the surface treatment such as electroplating or oil spraying, as well as easy internal fracture and dim color
9. Lock body: 800000 times of trouble free operation, 120 minutes fire test, national g3-94 mechanical lock class B anti-theft standard
① clutch driver: it comes from Israel's electromechanical conversion technology, adopts Japanese mabuqi imported motor with military quality, and the clutch is made of 304 precision casting. The process is complex and difficult to process, but it has rapid response, low failure rate and good safety performance. The common motor is made in China, so its life is very short, or the clutch is made of alloy material, so it is easy to wear and cannot open the door. The main reason is that the process is simple, the cost is low, but the failure rate is high
② large tongue: the whole piece is made of 304 precision casting, which is strong and impact resistant, and can withstand the static pressure of 9800 Newton. Generally speaking, the protruding part of the tongue is made of stainless steel (or even alloy), and then welded or riveted with the internal parts of the lock body, which is not strong enough and resistant to impact. For example, the high-end copper doors and stainless steel doors are more than 60-80 kg, and the cast aluminum explosion-proof doors are more than 120 kg, Therefore, 304 stainless steel is not used for investment casting, which is easy to be broken (such as loosening, deformation, fracture, etc.)
10. Surface treatment: adopt the international leading six layer nano process electroplating, plus electrophoretic sealing paint treatment, pass 220 hours neutral salt spray test, rable, lasting for 6-10 years. Other ordinary fingerprint locks are made of low-cost ordinary electroplating or oil spraying. Material manufacturers use ordinary zinc or even recycled materials. After electroplating or oil spraying, it seems that there is no big problem. Once more than one year, there will be shift, discoloration or peeling, which is very terrible, This is why many ordinary low-cost fingerprint locks use oil injection instead of electroplating
11. Installation: one second reversing, handle never drooping structure, the whole lock does not need to be left or right, do not fear that customers do not know the direction, refit does not need more holes (quick installation method), installation is fast and simple. When changing the direction, it is necessary to remove both the handle and the lock body, which is troublesome, complex and time-consuming
proct function introction and comparison
1. Magic password function: high security, anti peeping, safe and worry free, even if the thief is behind, because the thief does not know what your real password is. Many brands don't have this function, especially the cheap fingerprint lock, which is not safe when you use the password
2. Anti interference function: the acquisition head can resist light interference, even strong light, so it can be opened smoothly. Ordinary fingerprint lock as long as the sun is illegal to read fingerprints, can not open the door
3. Security anti lock function: the door is locked inside, the door can't be opened outside, even the mechanical key can't be opened, so it's safe inside. Many ordinary people don't have this function
4. Wechat networking door opening control function: there is no need to install another app to realize the real-time control of mobile phone wechat remote (as long as the mobile phone can be connected to the network, no matter where it is).

If you can't connect to the Internet, there's no difference between ordinary fingerprint lock and ordinary mechanical lock. It's just easier to open the door, but it still can't solve the problem you worry about your family
③ anti thief, lock cylinder alarm: the thief uses tools to open the door lock, such as master key unlock, tin foil unlock, single purchase unlock, violent unlock and forced unlock (need to be expanded), and the door lock immediately alarms for 5 minutes. At the same time, the alarm information is sent to the mobile phone wechat. No matter where you are, you can quickly know the status of the door lock and catch the thief to relieve the crisis, Protect your property. If it's an ordinary fingerprint lock that can't be connected to the Internet and there's no alarm notice, then your home will be looted
4. Anti gangster, threatening fingerprint alarm: as long as the gangster forces you to open the door, you just press the threatening fingerprint, and the alarm information is immediately sent to your family's mobile phone wechat when the door is opened normally. The gangster does not know that you have sent the alarm information, so your family can immediately take the alarm to easily solve the danger, so as to protect your personal and property safety. If it's an ordinary fingerprint lock that can't be connected to the Internet, you or your family can't do anything when they really encounter this kind of danger. If you resist, your life will be hurt. If you don't resist, your property will be looted
⑤ record reading: you can read the door opening record of the door lock on wechat at any time, and you can query the unlocking record without at home< (6) security smart home expansion: through mobile wechat, you can monitor infrared sensor, smoke alarm, door (window) magnetic alarm, gas leakage alarm, wireless cat's eye, webcam and other home security devices, so that you can know whether there are strangers, fire alarm, thief, etc Whether the gas leakage at home and real-time view of the scene at home, convenient and efficient all-weather protection of your home safety. If it's an ordinary fingerprint lock that can't be connected to the Internet, you don't know all the dangers that happen at home. When you know it, it's estimated that it's too late and everything can't be retrieved
5. Password trial unlocking function: the lock will be locked automatically for 5 minutes if the lock is unlawfully opened for 3 consecutive times. Ordinary people don't have this function, which increases the chance for the thief to crack the password
6. Emergency power function: emergency power supply, convenient and fast. Ordinary are using 9V external power supply, to the real use may be closed supermarket or to run a long distance to buy, very inconvenient
7. Normally open function: after opening this function, you can press the handle to open the door without passing any verification, such as meeting room, office and other special situations. Some brands do not have this function
8. Anti prying function (optional): as long as you forcibly pry open the panel, the door lock will sound an alarm
9. Anti technology opening function: This is the same as wechat networking, which can be set on wechat or on the door lock
