Refueling draft of mining machine

1. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system
unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity
on December 17, 2017, bitcoin reached an all-time high of $19850. On July 27, 2020, bitcoin broke through the $10000 mark again [2]<

from the transaction of things In 2008, the global financial crisis broke out. On November 1 of the same year, a person who called himself Satoshi Nakamoto published the white paper bitcoin: a peer-to-peer e-cash system [6] on the P2P foundation website, stating his new idea of e-money bitcoin came out. On January 3, 2009, bitcoin Genesis block was born
there are three bitcoins in total
compared with legal tender, bitcoin does not have a centralized issuer, but is generated by the calculation of network nodes. Anyone can participate in the manufacture of bitcoin, and it can circulate all over the world. It can be bought and sold on any computer connected to the Internet. No matter where they are, anyone can dig, buy, sell or receive bitcoin, And in the transaction process, foreigners can not identify the user's identity information. On January 5, 2009, bitcoin, which is not controlled by the central bank and any financial institutions, was born. Bitcoin is a kind of digital currency, which is composed of a series of complex codes generated by computer. The new bitcoin is made by preset program
whenever bitcoin comes into the view of mainstream media, mainstream media always ask some mainstream economists to analyze bitcoin. Earlier, these analyses always focused on whether bitcoin was a scam. Now the analysis is always focused on whether bitcoin can become the mainstream currency in the future. The focus of the debate is often on the deflationary nature of bitcoin[ 7]
many bitcoin players are attracted by the fact that bitcoin can not be added at will. Contrary to the attitude of bitcoin players, economists have a polarized attitude towards the fixed amount of 21 million bitcoin
Keynesian economists believe that the government should actively regulate the total amount of money, and use the tightness of monetary policy to timely fuel or brake the economy. As a result, they believe that bitcoin's fixed aggregate currency sacrifices its adjustability, and worse still, it will inevitably lead to deflation, thereby harming the overall economy. Austrian economists hold the opposite view. They think that the less the government intervenes in money, the better. The deflation caused by the fixed amount of money is not a big deal, even a sign of social progress
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. Bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network will get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer[ 6]
in 2009, when bitcoin was born, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25. When the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million[ 3]
bitcoin is a virtual currency with limited quantity, but it can be used to cash out: it can be converted into the currency of most countries. You can use bitcoin to buy some virtual items, such as clothes, hats, equipment, etc. in online games. As long as someone accepts it, you can also use bitcoin to buy real-life items
on February 25, 2014, the opening price of "bitcoin China" was 3562.41 yuan. By 4:40 p.m., the price had dropped to 3185 yuan, down more than 10%. According to the historical market data of the platform, on January 27, 2014, 1 bitcoin could be exchanged for 5032 yuan. This means that in less than a month on the platform, the price of bitcoin has dropped by 36.7%
on September 9 of the same year, the US e-commerce giant eBay announced that Braintree, its payment processing subsidiary, would start accepting bitcoin payments. The company has entered into a partnership with coinbase, a bitcoin trading platform, to begin to accept this relatively new means of payment
although the eBay market trading platform and paypal business do not accept bitcoin payment, Braintree customers such as airbnb, a travel house rental community, and Uber, a car rental service, will be able to start accepting this virtual currency. Braintree, whose main business is to provide payment processing software to enterprises, was acquired by eBay in 2013 for about $800 million
on the evening of January 22, 2017, fire coin, bitcoin China and okcoin announced on their respective official websites that in order to further curb speculation and prevent drastic price fluctuations, all platforms will start to collect transaction service fees from 12:00 noon on January 24, and the service fees will be charged at a fixed rate of 0.2% of the transaction amount, and the active transaction and passive transaction rates are the same[ 8] On May 5, according to the latest data of okcoin, the price of bitcoin has just set a new record, reaching a high of 9222 yuan by the time of publication. From 12:00 noon on January 24, China's three major bitcoin platforms officially began to collect transaction fees. On September 4, the central bank and other seven ministries and commissions announced that China banned virtual currency trading
on December 17 of the same year, bitcoin reached an all-time high of $19850
on November 25, 2018, bitcoin broke the $4000 mark and then stabilized at more than $3000[ 9] On November 19, cryptocurrency resumed its decline, and bitcoin fell to the $5000 mark for the first time since October 2017, e to BCH's hard bifurcations and the regulatory authorities' enhanced scrutiny of the initial token issue (ICO)[ 9] At 4:30 a.m. on November 21, the offer of bitcoin on the coinbase platform fell below $4100, a 13 month low
in April 2019, bitcoin broke the $5000 mark again, reaching a new high in the year[ 10] On May 12, bitcoin broke through $7000 for the first time in nearly eight months[ 11] On May 14, according to the offer of coin market cap, bitcoin stood at $8000, up 14.68% in 24 hours[ 12]

overseas mining rise: batch construction of us factories, On November 1, 2008, a self styled Satoshi Nakamoto published a bitcoin white paper, bitcoin: a peer-to-peer electronic cash system, on the P2P foundation website, stating his new idea of electronic money bitcoin came out
Wang yuexinyi, Professor of mathematics at Kyoto University, was born on January 3, 2009. Bitcoin uses distributed ledger to get rid of the constraints of third-party institutions, which Nakamoto calls "blockchain". Users are willing to dedicate the computing power of CPU and run a special software to be a "digger", which will form a network to maintain the "regional chain". In the process, they also generate new money. Business is also extended on this network. Computers running this software are scrambling to solve the problem of irreversible code, which contains several business data. The first miner to deal with the problem will get a 50 bitcoin reward, and the relevant trading area will join the chain. As the number of "miners" increases, the difficulty of each puzzle also increases, which keeps the proctivity of bitcoin in each trading area at about 10 minutes
in 2009, Nakamoto designed a digital currency, namely bitcoin. The booming bitcoin market has gone up and down, and the identity of its founder "Nakamoto" has always been a mystery. Rumors about "the father of bitcoin" involve from the US National Security Agency to financial experts, and also give bitcoin a mysterious aura
according to foreign media reports, computer scientist Ted Nelson released a video on the Internet on Sunday, saying that he has determined that the founder of bitcoin is Shinichi Mochizuki, a professor of mathematics at Kyoto University. The founders of bitcoin have always used

2. Pure graphics card miner, now dig BTC, LTC, NMC, etc., which kind of currency is more profitable? Have the actual operation of the predecessors, give more advice!!!!!!!!!!!

3. It's about helping children build self-confidence and behavior patterns. What is reflected from the problem that children are "unwilling to solve problems by themselves" is how our parents once treated their children's attitude and way of dealing with difficulties. There are several reasons for children's "always asking others for help"

1. It is related to parents' underestimation of children's ability

for example, the average level of a child is that he will "welcome" and "goodbye" at nine months old, cover himself at one year old, take off his socks at three months old, and so on. When the child is two years old, he will begin to like to take shoes, table and broom for his parents. When the child takes doing housework as a very happy thing, our parents think that he is making trouble, not giving support and guidance, but drinking and scolding or putting things away. Let children feel that their ability is too weak, their ability can not be recognized by alts.

2. It is related to the children's way of doing things from childhood

for example, when a child wrestles, our parents usually don't help him summarize and recognize the reasons for wrestling, encourage and support him to try again, but often remind him loudly: & quot; Did you forget that you fell there& quot; The implication is that you dare to go even if you have fallen there. I don't know how to be afraid! And such a kind of reminder forms that children don't know how to face the behavior pattern when they encounter difficulties, and that children focus all their attention on "difficulties" when they encounter difficulties, rather than thinking about how to solve them

3. It is related to parents' failure to help their children accumulate experience in facing difficulties

any behavior pattern and ability of a child needs our parents to accumulate relevant experience for him. Based on the above two reasons, our parents help their children to accumulate the experience of giving up when they encounter difficulties, instead of helping them to accumulate the experience of meeting difficulties, facing difficulties and solving difficulties, so they "always ask others to help."

after understanding the reasons behind children's behavior, please pay attention to the following points in your daily life:

1. Be an encourager and supporter of children

when your child asks you to solve the problem, you will study and analyze the problem with him, then work with him to solve the problem, and tell the child afterwards what you have done well in what you have just done, and encourage and praise him. And tell him: & quot; You believe he will do better and better next time& quot;<

2. Be a cheerleading team to help children build self-confidence.

give children more opportunities to do things for us. And in the side for his encouragement, refueling, and timely guidance, so that he can successfully complete, so as to enhance his self-confidence

3

we will not be the "magnifier" and "intimidator" of children's difficulties. We need to be difficult "analysts" and "focus shifters"! In other words, when children encounter difficulties, what we should do is: let children focus on how to solve the problems, that is, what methods can solve the problems, not the difficulties themselves. For example: climbing up and falling down, go with him to see why I fell down just now? Is it hand or foot?... After finding out the reason, encourage him to try again and tell him that you will support and protect him. Come on

in this way, we help children establish an achievement mechanism that they are willing to face when they encounter difficulties - I can! I'm great! I will do! In this way, our children will have this kind of thinking mode to think and seek solutions when they encounter difficulties, and become a confident and brave child!

female: willows are withered. When they are green again, the flowers are withered. When they are blooming again, the swallows are gone. When they are flying again, however, time flies away, just like running water
man: Yes, the broadcasting theme of our red scarf radio station is "cherish time"
to cherish time is to cherish one's own life. Since ancient times, no one who has made great achievements has not cherished time. Here is a story about cherishing time
Edison only went to primary school for three months in his life. His knowledge came from his mother's teaching and self-study. His success should be attributed to his mother's understanding and patient teaching since childhood, which made Edison, who was originally regarded as an incompetent child, become a world-famous "king of invention" when he grew up
Edison was curious about many things since he was a child, and he liked to experiment with them himself until he understood the truth. When he grew up, he devoted himself to research and invention according to his own interests. He set up a laboratory in New Jersey and invented more than 2000 kinds of things in his life, such as electric lamp, telegraph, phonograph, video camera, magnetic separator, crusher and so on. Edison's strong research spirit made him make great contribution to the improvement of human life style
"waste, the biggest waste is to waste time." Edison often said to his assistant“ Life is too short. Think more and do more with less time. "
one day, Edison was working in the laboratory. He handed his assistant an empty glass bulb without a light port and said, "you measure the capacity of the bulb." He bowed his head to work again
after a long time, he asked, "what's the capacity?" He didn't hear the answer. He turned his head and saw his assistant measuring the perimeter and inclination of the bulb with a tape measure. He took the measured number and put it on the table to calculate. He said, "time, time, how do you spend so much time?" Edison came over, picked up the empty light bulb, filled it with water, handed it to his assistant, and said, "pour the water in the measuring glass, and tell me its capacity right away." The assistant read out the number immediately
Edison said, "what an easy way to measure. It's accurate and time-saving. Why can't you think of it? Is it not a waste of time? " The assistant blushed. Edison murmured: "life is too short, too short, to save time, do more things!"
female: the pace of time is silent. Winter goes and spring comes. The days turn back and forth. If you don't pay attention, the years will slip away from you. It will not give any forgiveness to those who delay time, nor will it be favored by anyone's begging. People may never run away from time, but we can at least make use of time and cherish it. Now let's listen to how other celebrities cherish time
Why do celebrities succeed? Because they know how to race against time
Mr. Lu Xun, a great writer, has a saying, "I'm not a genius. I just spend other people's coffee time at work." Because he knows how to use time, he left us more than six million words of spiritual wealth. Lu Xun regarded time as life. "Wasting other people's time for no reason is tantamount to murder," he said Not long before his death, Lu Xun wrote articles and diaries in his hospital bed. It was by cherishing time that Lu Xun wrote so many good articles in his limited life
mathematician Chen Jingrun, day and night, devoted himself to the study of mathematical problems -- Goldbach conjecture. There are several sacks in the draft of calculus alone, but he finally proved this problem and took off the crown of mathematics
Hugo is a famous French writer in the 19th century. Once, in order to create a new work, he nervously put into work. However, he was constantly invited to dinner. Out of courtesy, he had to go, which wasted a lot of time. Finally, he came up with a wonderful way to cut off half of his hair, so that he would not be able to go out to meet guests and stay at home and concentrate on his creation. It is because he cherishes his time so much that Hugo can continuously offer his great works to people.
