Fil coin mining speed chain Xingjia mine pool

2. I also saw the news of DF's first round of mine pool quota in several communities. Many people should grab it. You said that they would definitely get the quota. Yesterday, a friend of my community said that their community seems to have won the node. Welfare means that they can get a certain quota 100%. You should be talking about this node activity. The first round is definitely the best. If you can't get 2 or 3 rounds, the quota will be improved. If you try hard, you will get it
there should be no problem with the calculation power of fil. After all, IPFs is quite influential, both in technology and overall planning.

3. It is not recommended to buy cloud computing power. There are too many uncertainties and risks.

The building owner mentioned three problems: how to mine, how to earn more, which mining machine is strong. Here is a brief answer

1. how to mine. The way for ordinary investors to participate in mining is to buy mining machines. After the main network line is connected to the main network, they can mine. Generally, mining machine manufacturers will provide hosting services. Mining machines are put in their computer room, and professional personnel will take care of them for you. You don't need to spend much energy on it

2. how to make more money. The first point is to dig the head mine, that is, to participate in the mining within 3-6 months after the main network goes online. Because the number of filecoin is fixed, but the number of miners participating in the mining will be more and more, so the earlier you participate in the mining, the more you get. This can be referred to bitcoin mining. The second point is to choose the right miner. The mining efficiency of different miner is certainly not exactly the same. For companies with strong technology and strength, their miner can dig more in unit time

3. which mining machine is better. This should remind the owner that he should have his own judgment and don't easily believe any miner's words, because now the miner's market is full of fish and dragons, and everyone will say that his family is good, and there are more and more people playing with money to cut leeks. When choosing a miner, directly ask the miner these questions:
   

   1, what's the miner number

   2, what is the total storage capacity

   3, what is the block rate

   4, what is the total yield

   5, what is the average yield per T

   the real data proves the efficiency of the miner. If the miner can't show the data, it's useless to give you a scrap iron. Identify these five data, which is directly related to your investment and rate of return

< / OL >

that's about it. The second official large-scale developer test is about to start. The owner can pay attention to it. The miner who can get a good place in the test and keep the ranking stable is the miner with real strength and technology. If conditions permit, it's better to visit the company's technical team, computer room, etc

5. First, the most common mining method: Hardware mining
Second, the mining method of sin in music: mobile phone software mining
Third, the latest mining method, trading is mining, lock is mining.

Zhang Jian of cloud data trade took out 5000 tons of gold to make 500 million gold coins. It's not necessary to use his head to know that it's fake. It's a bit ridiculous if someone really believes it. Let's not talk about anything else. 5000 tons of gold alone can't be taken out by ordinary countries, let alone indivials. It is understood that the earth has only mined about 170000 tons of gold, most of which are used in jewelry, instry, private investment and other fields. The total gold reserves of various countries are about 33259.2 tons

the real name of Zhang Jian, the founder of cloud data trade, is song miqiu. Many legendary experiences about her from Wuchang City, Heilongjiang Province and her graation from Renmin University are fabricated. In 2013, the eighth case listed in the top ten pyramid selling cases by the State Administration for Instry and Commerce and the Ministry of public security is the pyramid selling case of Cloud Data Trade Alliance. The so-called 5000 ton gold is 500 million gold coins, which is a gimmick of his pyramid selling. In 2017, with the support of Indonesia police and China Embassy in Indonesia, Song Miqiu, a leader of pyramid selling of Cloud Trading MLM and a major criminal suspect, were arrested from Indonesia. p>

6 A project can be completed by Party A in 63 days and then by Party B in 28 days. If Party A and Party B cooperate, it will take 48 days to complete. Now it's going to take 42 days for a, and then it's going to take B. how many more days
63 A + 28 B = 48 (a + b) 3A = 4 B a daily workload of 1-92; In a village, m ha of corn was planted, and the total yield was n kg; The planting area of rice is p ha more than that of corn; The total yield of rice is more than twice that of corn. Write the formula for the yield per unit area of corn and rice. If the denominators of the two expressions are different, divide them together
corn: the total yield is n kg, m ha,
then: n / M kg per ha.
rice: the total yield is more than 2 times of corn, Q kg, that is, 2n + Q kg
the planting area is p ha more than that of corn, which is m + P kg
then: 2n + Q / M + P kg per hectare
n / M kg per hectare for corn, 2n + Q / M + P kg per hectare for rice, and then divide into two parts
n (M + P) / M (M + P) kg per hectare for corn,
m (2n + Q) / M (M + P) kg per hectare for rice
9, How much is the scholarship for each of them
Zhang San's number of winners * 2 / 9 = Li Si's number of winners * 1 / 4
it can be set as follows:

Zhang San's number of winners = 1 / 4
Li Si's number of winners = 2 / 9
then:
Zhang San's number of winners * 2 / 9 = Li Si's number of winners * 1 / 4
1 / 4 * 2 / 9 = 2 / 9 * 1 / 4
the ratio of Zhang San's number of winners to Li Si's number of winners is 1 / 4:2 / 9 = 9:8
then it is distributed in proportion,
170 * 9 / 9 + 8 = 90 yuan, Zhang San won the prize
170 * 8 / 9 + 8 = 80 yuan, Li Si won the prize

let an X and a Y
greatest common divisor 4,
least common multiple:
4 | x y
| -
A B
least common multiple = 4 * a * b = 120
A * b = 30, AB is reciprocal, so a = 2, B = 15
x = 2 * 4 = 8, y = 15 * 4 = 60
so, these two numbers are 8 and 60.
11. In the model airplane competition, the ratio of people divided into group A and group B is 7:8. If eight people are transferred from group B to group A, the number of people in group B is four fifths of that in group A. how many people are there in total< A bucket of salt water weighs 200 kg and the salt content is 10%. How many kg of water should be evaporated to make the salt content reach 16%

the weight of salt is the same, the salt is: 200 * 10% = 20kg

when the salt content is 16%, the total amount is: 20 / 16% = 125kg

then evaporate water: 200-125 = 75kg

13. A bottle of drink, after drinking 25%, weighs 950g. When drinking 50%, weighs 700g, how many kg are the drinks and bottles

drink water: 50% - 25% = 25% weight: 950-700 = 250g

total weight of water: 250 / 25% = 1000g = 1kg

bottle weight: 950-1000 * 75% = 200g = 0. 2kg

14. There are two scoring methods for a certain mathematics competition: the first is to get 5 points for answering a right question, 2 points for not answering, and no points for wrong answers; In the second way, 40 points will be given first, 3 points will be given if the answer is right, 1 point will be dected if the answer is wrong, and 81 points will be given to a student in both ways. How many questions are there in this competition

answer question x correctly and question y not correctly, Wrong answer to Z
5x + 2Y = 81
40 + 3x-z = 81 leads to 3x-z = 41

from 5x + 2Y = 81, we can see that x must be singular
from 3x-z = 41, we can see that 41 + Z must be divided by 3

when z = 1, x = 14, y = 3
when z = 4, x = 15, y = 3
when z = 7, x = 16, y = - 2, y = - 2 The project team needs to build a canal: if it needs to build 8 meters more every day, it can be completed 4 days in advance; If the construction is less than 8 meters per day, the completion will be delayed by 4 days. What is the length of this canal<

suppose the specified time is x days
according to the meaning of the question, the workload of 4 days is 8 [x-4], then it can be repaired in one day: 2 [x-4]

[2 (x-4) - 8] [x + 8] = x * 2 [x-4]

[2x-16] [x + 8] = 2x ^ 2-8x

2x ^ 2 + 16x-128 = 2x ^ 2-8x


8x = 128


x = 16

that is, the specified time is 16 days, It can be repaired in one day: 2 * [16-4] = 24

so the total length is: 16 * 24 = 384m

16. What is the minimum number when a number is divided by 3 to 1, by 4 to 2, and by 5 to 4

the three numbers 3, 4 and 5 in the question are reciprocal

then [4,5] = 20; [ 3，5〕=15〔 3，4〕=12〔 3，4，5〕=60

in order to divide 20 by 3 to 1, use 20 × 2=40

make 15 be divided by 4 to make 1, use 15 × 3=45

make 12 be divided by 5 to make 1, use 12 × 3=36

then, 40 × 1＋45 × 2＋36 × 4 = 274,

because, 274 & gt; 60, so 274-60 × 4 = 34 is the number

17. A number is divided by 3 to 2, by 7 to 4, and by 8 to 5. What is the minimum number

the three numbers in question 3, 7 and 8 are reciprocal

then [7,8] = 56; [ 3，8〕=24〔 3，7〕=21〔 3，7，8〕=168

in order to divide 56 into 3 and 1, 56 is used × 2=112

make 24 be divided by 7, and 1 is left, then 24 is used × 5=120

make 21 be divided by 8, and 1 is left by 21 × 5=105

then, 112 × 2＋120 × 4＋105 × 5 = 1229,

because, 1229 & gt; 168, so, 1229-168 × 7 = 53, that's the number

18. A number divided by 5 to 4, divided by 8 to 3, divided by 11 to 2, to find the minimum natural number satisfying the condition

the numbers 5, 8 and 11 in the question are reciprocal

then [8,11] = 88; [ 5，11〕=55〔 5，8〕=40〔 5，8，11〕=440

in order to divide 88 by 5 to 1, 88 is used × 2=176

divide 55 by 8, and then divide 1 by 55 × 7=385

make 40 be divided by 11, and the remaining one is divided by 40 × 8=320

then, 176 × 4＋385 × 3＋320 × 2 = 2499,

because 2499 & gt; 440, so 2499-440 × 5 = 299, that's the number

19. There are six students in a row for every nine students, two students in a row for every seven students, and three students in a row for every five students. How many students are there at least in this grade Teacher Zelin's question)

in the question, the numbers 9, 7 and 5 are reciprocal

then [7,5] = 35; [ 9，5〕=45〔 9，7〕=63〔 9，7，5〕=315

in order to divide 35 by 9 and 1, 35 is used × 8=280

make 45 be divided by 7 and 1, use 45 × 5=225

make 63 be divided by 5 and 1, then use 63 × 2=126

then, 280 × 6＋225 × 2＋126 × 3 = 2508,

because, 2508 & gt; 315, so 2508-315 × 7 = 303, that's the number

20. There are five students in a row of nine, one in a row of seven and two in a row of five. How many students are there in this grade Happiness 123 teacher asked the question)

in the question, 9, 7 and 5 are reciprocal

then [7,5] = 35; [ 9，5〕=45〔 9，7〕=63〔 9，7，5〕=315

in order to divide 35 by 9 and 1, 35 is used × 8=280

make 45 be divided by 7 and 1, use 45 × 5=225

make 63 be divided by 5 and 1, then use 63 × 2=126

then, 280 × 5＋225 × 1＋126 × 2 = 1877,

because 1877 & gt; 315, so 1877-315 × 5 = 302, that's the number

the story of a scientist

Boyle, a skeptical chemist, was born in an aristocratic family in Ireland on January 25, 1627. His father was a count and his family was rich. He is the youngest of fourteen brothers. Boyle was not very smart when he was a child. He stuttered and didn't like lively games, but he was very studious and liked to read and think quietly. From 1639 to 1644, he traveled to Europe. During this period, he read a lot of natural science books, including the famous book dialogue about two world systems by Galileo, an astronomer and physicist. The book left a deep impression on him. His later famous work skeptic chemist imitated this book
e to the chaos of war, the death of his father and the decline of his family, he came back to live in London with his sister in 1644. He began to study medicine and agriculture there. He came into contact with a lot of chemical knowledge and experiments, and soon became a well-trained chemical experimenter and a creative theorist. During this period, he, together with many scholars, organized a scientific society to hold weekly seminars, mainly discussing the latest development of natural science and the problems encountered in the laboratory. Boyle called the organization "invisible University.". This society is the predecessor of the famous "Royal Society" whose purpose is to promote the development of natural science. Boyle is an important member of the society. As the branch of the society was located in Oxford, Boyle moved to Oxford in 1654. In Oxford, he established a well-equipped laboratory and employed some talented scholars as assistants to lead them in various scientific researches. Many of his scientific research achievements were made here. That epoch-making masterpiece
