Calculation period

1. How many metal lock sharing procts are there? If you are in a hurry, you usually have to see how many cycles it operates. Can't the deposit be refunded?

2. The reason for computing power contract is that bitcoin mining has become more and more professional, and mining has higher and higher requirements on site and technology. Personal mining has become no longer relaxed and pleasant
therefore, computing power trading platforms like 58hash emerge as the times require. Users only need to purchase computing power, trust computing power to the computing power trading platform, pay a certain maintenance fee, and the computing power hosting platform will uniformly maintain the mining machines, and issue the extracted bitcoin to users on time.

3. The computing power contracts of FTX exchange are futures contracts settled according to the average mining difficulty of bitcoin in a certain period of time. These futures contracts also roughly reflect the whole network computing power of BTC in that period. Of course, every calculation contract on FTX exchange also has a start date and a maturity date, which usually starts on the first day of each quarter and ends on the last day of each quarter.

4. Now, if we are mining in the computing power bee, the income is still OK. There are two parts of income. In addition to hoarding the bitcoin g by the current computing power, there can also be HBT's reward income, which can be used to re invest the computing power contract and add the computing power. The way of re investment can make the computing power grow faster and faster, and dig more and more coins
as long as the HBT reward is always there, it is equivalent to re investment, and mining can be carried out permanently in theory. The purchasing power is calculated in a three-year cycle, but in fact, the income from mining is far greater than the three-year cycle.

5. It's hard to say. If the currency price continues to fall, the miners generally lose confidence in bitcoin, and the mining income is seriously lower than the mining cost, then a large number of miners will stop mining, and the computing power will drop sharply. In addition, because the major countries in the world adopt a more stringent attitude towards bitcoin, such as China and the United States, bitcoin's computing power may also drop sharply, or even disappear

but bitcoin mining as an infrastructure, if bitcoin can continue to exist, although the income of mining is reced, for the security of the whole bitcoin network system, some big bitcoin companies may invest in mining to maintain the security of bitcoin network system. In addition, the future of bitcoin will become more clear and bright. Bitcoin's computing power will not decrease, but will increase.

6. Generally speaking, this kind of power contract is permanent, and 58coin should be the same. You don't have to make your own choice. Unless the income you have g up for ten consecutive days is less than the electricity charge, the contract will be terminated. But this kind of continuous excavation is impossible.

7. How many cycles does the computing power of the mine help the proct? Is the rent refundable? This is not very good.

8. There are three biological rhythms in human body: physical strength, emotion and intelligence; Emotion has a cycle of 28 days; Intelligence has a cycle of ups and downs in 33 days, and each
goes back and forth like a clock. From the date of birth, it is estimated that each rhythm passes through 1 / 4 of the cycle time as the peak day, and the 2-3 days before and after the peak day is the "climax area". After the peak day, it begins to pass the
degree to the low tide period, and reaches 1 / 2 of the cycle time as the alternating day of high and low periods, which is called the "critical day of decline", and then enters the
low tide period. The day that reaches 3 / 4 cycle is the low tide day, and the 2-3 days before and after it is the "lowest tide period",
after the low tide day, it begins to rise, and when it reaches the end of the whole cycle, it is called the "rising critical day" and then enters the next
cycle. One or two days before and after the two critical days are called critical danger period
if you master these three rhythms, you can predict the tendency of your physical strength, emotion and intelligence in a certain period of time, reasonably arrange your various activities, and seize the golden time to work, study and innovate in the climax; When you are in a low tide or critical period, you should pay attention to going out and doing things, especially when you are in a "double critical day".

Firstly, the electron is negatively charged. When the electron moves in the magnetic field, it will be affected by the Lorentz force perpendicular to the velocity direction:

fro = QVB... ①

under the action of Lorentz force, the electron moves in a uniform circular motion

F direction = fro... ②

and f direction = MV & #/ R... ③

simultaneous solution ①, ②, ③ the radius of electron motion r = MV / QB...... ④

v= ω R... ⑤

simultaneous ④ and ⑤ get:

1 ω= QB / M...... ⑥

so t = 2 π/ω= two π M / QB...... ⑦

because the magnetism of the magnet comes from the current, the current is the movement of the charge, so generally speaking, the magnetic field is generated by the change of the moving charge or electric field

from the point of view of modern physics, the ultimate components of charge in matter are only electrons (with unit negative charge) and protons (with unit positive charge), so negative charge is a point object with excess electrons, and positive charge is a point object with excess protons

extended data:

the relativity of the motion of the magnetic field is the same as that of the field source. The observer and his detection instrument can not measure the magnetic field proced by the moving field source, but can measure the magnetic field of the field source when the velocity is different from that of the field source

for example, in the reference system of the earth's surface, we determine that the electron at rest on the earth's surface does not proce a magnetic field, but the electron at rest on the earth's surface is constantly rotating with the earth's surface and around the sun

For another example, the current that causes the wire to generate an external magnetic field is the result of the directional movement of a large number of electrons. When the current carrying wire generates a magnetic field, each moving electron is not disturbed by the magnetic field of other electrons, because all electrons in the same row have the same magnetization and can not feel the existence of other electron magnetic fields
