Bitcoin hamburger
1. Germination stage: the real germination stage of blockchain was from 2007 to 2009. In 2008, a Japanese American with the pseudonym of Nakamoto first expounded a new fantasy report on electronic money in the form of a synonym on the cryptography discussion group, and bitcoin came out. As early as 2007, Nakamoto began to explore a series of new technologies to create a new currency. On October 31, 2008, bitcoin white paper was released, and on January 3, 2009, bitcoin system officially began to operate
the main technologies supporting bitcoin system include hash function, distributed ledger, blockchain and asymmetric encryption; It can be seen that these technologies build the initial version of the blockchain, and it can also be said that the blockchain is the underlying technology of bitcoin. During the three years from 2007 to 2009, bitcoin was an experimental stage in which a very small number of people participated, and the real commercial activities had not really started
2. "Geek" niche stage: here, "geek" refers to people who are crazy about Internet technology and take technological innovation as fashion and life. On February 6, 2010, the first exchange of bitcoin appeared. On May 22 of the same year, someone bought two hamburgers with 10000 bitcoins. On July 17 of the same year, the exchange Mt. GOx was established, marking the official inflow of bitcoin into the market. Nevertheless, the only people who can really understand and enter the market to participate in bitcoin trading are geeks who are keen on Internet technology. They discuss bitcoin technology on the forum, mine for bitcoin on their own computers, and then buy and sell bitcoin on Mt. GOx. Now these geeks have become billionaires
3. Market brewing stage: the price of bitcoin was $13 at the beginning of 2013, but on March 18 of the same year, the government of Cyprus closed the bank and stock market e to the financial crisis, which made the price of bitcoin soar, and the highest price rose to $266 in April. On August 20 of the same year, the German government confirmed the currency status of bitcoin. On October 14, China network announced the opening of bitcoin payment channel. In November, the US Senate hearing also confirmed the legitimacy of bitcoin. On November 19, the price of bitcoin rose to US $1242, forming a new high. Nevertheless, the foundation for blockchain to enter the mainstream social economy is not yet available, and the soaring price of bitcoin is only e to over optimistic expectations. The containment of China's banking system, the collapse of Mt. GOx and other events made the price of bitcoin continue to fall. At the beginning of 2015, the price of bitcoin has dropped below $200. From 2013 to the beginning of 2015, the public began to understand bitcoin and blockchain
4. The mainstream period of blockchain: on June 23, 2016, the United Kingdom left the European Union, the fifth nuclear test of North Korea in September, Trump's election in November and other events, the uncertainty of the world's mainstream economy led to the recovery of bitcoin with the function of risk aversion. The market demand was large, and the increase of trading volume made the price of bitcoin soar from $400 in 2016 to $20000 in 2017, The wealth effect of bitcoin and the transaction overflow caused by network congestion of bitcoin have led to the outbreak of other series of virtual currencies, as well as a variety of blockchain applications, resulting in the emergence of a large number of blockchain assets that are 100 times, even 1000 times and 10000 times, which has aroused the crazy pursuit of the world, Subsequently, the Chicago Mercantile Exchange launched bitcoin futures trading, marking that bitcoin has officially entered the mainstream investment proct series, and bitcoin and blockchain have entered the global attention
5. Instry landing stage: after the market frenzy in 2017, the virtual currency and blockchain have been adjusted in terms of market, supervision, cognition, etc. in 2018, returning to rationality. In 2017, many blockchain projects that follow the blockchain technology will graally die out with the cooling of the market, and the projects with real blockchain applications will be initially implemented. 2018 is not only the first year of the blockchain, but also a gold rush period for the blockchain. After the waves wash away the sand, what remains is relatively good gold
from the perspective of the history of blockchain development, blockchain technology is not yet mature and is currently in the growth period. The specific practical application of blockchain is only used in the financial field. It still needs a long way to go to apply blockchain from other instries. However, we should grasp the trend of blockchain and actively learn from the new field of blockchain.
If you go back to seven years ago and choose a new investment opportunity, you will choose to invest in stocks, and then wait for the 15 year bull market to multiply your assets; They may also invest in real estate, and then wait for the real estate outbreak in 16 years to double their assets. However, if we chose to invest 10000 yuan in bitcoin seven years ago, we could sit on 66.2 billion yuan in 17 years, a rise of more than 6 million times
as we all know, the currency market in 2018 was a tragic year. At the beginning of 2018, the price of bitcoin was at the highest level in history, and the concept of blockchain began to heat up. A lot of people who originally belonged to the outside circle swarmed in to participate in entrepreneurship, employment and money buying. The prospect of the currency market seemed to be very good. Later, as we all know, as the price of currency fell again and again, the newly established blockchain media fell down one by one, and those new people who followed suit to buy currency were trapped in a high position to discuss; Bitcoin& ldquo; Blockchain & quot; There's less and less sound in the room. The coin ring gives these new comers a sense of cruelty
More than 90% of the people are trapped here, and faith is a very strange thing; Like the queen in the last kingdom of American TV series, the Danes gather to attack, she still says & mdash& mdash; God will punish the infidels and calm downlast year, all digital currencies and ICO platforms were shut down in China, and all countries in the world have put restrictions on them. At this time, few ordinary holders are willing to sell, and they basically hold them. This requires great determination, life problems, currency speculation problems, all kinds of problems may cause no longer hold; These problems cause a lot of trouble, so many people do not live well. After half a year, the instry that countries all over the world have entered is & lt; Blockchain & quot; And digital currency! In the game of blockchain, many countries have made some moves, and the holders are also on the sidelines
regret is sure to regret. This brother will regret that he wants to jump from a building. because 10000 bitcoins are worth about 300 million yuan now, eating pizza with more than 300 million yuan is believed to be the most expensive pizza in the world. This brother will regret that he forgot to take it when he won the lottery. If there is no accident, This will be the most regretful thing in his life. However, since he would have bought bitcoin at the beginning, it shows that he has investment consciousness. Besides bitcoin, he should have bought some other things, but these things may not make money without bitcoin, but this kind of investment consciousness is very good
as long as we carefully observe the growth process of bitcoin, we can see the clue. When it first appeared, people who knew it would be very interested in its growth, and would often pay attention to the growth environment around it, such as the financial environment, circulation channels and so on. These environments can be said to be a very important factor in the growth of bitcoin, if you can observe this kind of growth environment in detail, you will be closer to success
At present, a small number of people in the society are extremely enthusiastic about bitcoin. They think that bitcoin is a perfect thing, and there is unlimited imagination in the future
they even think that only holding legal currency can see cash out. Most will hold bitcoin for a long time
therefore, different people's cognition of bitcoin will lead to different value attributes of bitcoin

There are many versions of Microsoft's latest Windows 10, including s, home, pro and enterprise. In terms of functional experience, win10 professional and enterprise are undoubtedly the most perfect
which is better, win10 professional edition or enterprise edition
win10 professional edition is mainly for technology lovers and enterprises / technicians
win10 Enterprise Edition is mainly for large and medium-sized enterprises, and its core selling point is to add corresponding functions for enterprise users, such as deploying and managing PC, windows to go, virtualization and advanced security
it should be noted that ordinary users can't upgrade directly from Windows 7 and windows 8 to windows 10 enterprise edition, but they can upgrade to professional edition
in terms of functions, win10 is more functional than enterprise edition, such as supporting refs partition, windows to go and other functions. However, considering that ordinary users can hardly use the functions of Enterprise Edition. In addition, because enterprise edition has added more functions, it takes up more hard disk space, and the authorized fee of genuine edition is more expensive (piracy does not need to be considered, so enterprise edition can go directly), Therefore, it is the best choice for ordinary indivial users to choose major, and it is better for enterprise users to choose enterprise edition
in short, the choice of win10 professional edition and Enterprise Edition mainly depends on the use requirements or the use objects

secondly, bitcoin is obtained according to some algorithm. According to my understanding, there are specific parameters. As long as the parameters are changed, there will be nt and NT. As long as the formula is obtained and the parameters are slightly changed, a new currency will be generated
again: who gives it value? It is said that some people used a lot of bitcoin in exchange for a hamburger at the beginning, and now it can be sold for more than 2000 US dollars. The value depends on the number of speculators, so once I have fewer people, its price will definitely come down
when we talk about the value of bitcoin, we are actually talking about the value of bitcoin. In other words, we're talking about the value of bitcoin, essentially the price of bitcoin
how to measure the price of bitcoin? To take an extreme example, if there is a bitcoin tycoon who grabs all bitcoin through his amazing IQ, how many legal coins can he exchange? I think it's probably the only way to exchange these bitcoins for a hamburger< In fact, bitcoin has no practical value. It's a kind of artificial currency
in other words, virtual currency itself does not exist, because many people believed in it and later established order. It's a community behavior, a community of cultures and developers from all over the world. It establishes order through the Internet system. In essence, bitcoin is endowed with value by a common group, because many people believe it is valuable
similarly, the value consensus of legal currency is e to the endorsement of the government and the recognition of the value of the law, that is, the group consensus gives value
therefore, bitcoin can be regarded as valuable under certain circumstances, but the groups that give it value and the government are basically two different concepts, and the risk is much greater than that of legal currency
therefore, whether there is value or not depends on different opinions. PS: indivial investors are not recommended to speculate. Prices are all controlled by big investors. If others want to go up, they will go up, and if they want to go down, they will go down. Indivial investors are all cut leeks. Don't be jealous of how much money others earn
I hope my answer will be helpful to you and help him. Thank you.
The first thing to be clear is that the gold mark is not the mark. If it is the mark, it will not be in circulation after the introction of the euro, and the gold mark is earlier. The 26000 gold mark is obviously not a gold coin, it should be a paper currency. The value of gold and paper currency of gold mark is very different
Goldmark is the currency unit issued and circulated by the German Empire (German: Deutsches Kaiserreich) from 1873 to 1914 to replace the currencies issued by the States before the unification of the German Empire
I hope this kind of answer can help you, remember to choose the best
in children's eyes, society is always full of truth, goodness and beauty, and life is sweet and colorful. In the eyes of alts, society has two sides, both the true, the good and the beautiful, and the fake and the ugly. Life is full of ups and downs. Why is there such a big difference between alts and children? There is only one conclusion: This is the most fundamental difference between mature and immature
in the world, everything has two sides. The rich experience of alts determines that they see things more comprehensively. But the child wants to move toward the mature, must need to experience some things. Some people say: "life is a big training ground, a stage to sharpen people." In this special stage, everyone will encounter happy things and sad things. Sad things will make people bear great pain, happy things will make people have a good mood. If we face sad things all day long, people are easy to lose confidence, and then abandon themselves and decadent; In the face of happy events all day long, people will be confused by the things in front of them, lack of social experience, and easy to be deceived. Just as plants can't lack sunshine and rain, people's experience can't lack happiness and sadness<

the hot summer is often a time to test people's perseverance. Everyone's perseverance is different, but the door to knowledge is always open. Just look at you in the distance. Through the heat, it means that you have embarked on a new starting point. Today, I happened to read a book and saw Tong Dizhou's text. Tong Dizhou's study was very poor, but he worked hard and made good use of his study in the morning and evening. He went from the last to the first. I get a lot of inspiration from it: no matter what you do to succeed, you must pay hard work and sweat to get the joy of harvest. This reminds me of a famous saying: "no pains, no gains." What a good saying, my spirit came up all of a sudden, I found the spiritual needs of the tonic. As in the past, I studied hard. Every day, the teacher took us to the sea of knowledge and broke through many difficulties. Got a good trophy
it strengthened my faith, trained my will and kept learning to climb. Waiting for the next challenge...

when you stay at home and do your homework, you can't help feeling a little boring. Besides reading books or watching TV, you can play some cards with your grandparents to have fun. My mother is very strict with me, often nagging in my ear, must let me review language, number English, say what "soon graated, junior high school is still so relaxed!" I had no choice but to accept my fate. In only five days, I finished half of my homework! Amazing! Although I breathed a sigh in my summer vacation, I still "study behind closed doors". Alas, bad luck
swimming is an indispensable sport for me in summer. If I jump up in the blue waves, I will let the cool pool water cool my whole body and soak my heart. Although I occasionally drink a few water in the swimming pool, I still feel great and cool in the pool! In the hot summer, to a few dog crawl, a few breaststroke, there is a sense of leisure fashion
in summer vacation, there is also freedom and happiness in plain life. Boring and happy life! Ha ha<

in the summer vacation, I saw my mother always worried, and always looked back and forth in the mirror. I knew that my mother was worried about her growing fat. Since the summer vacation, my mother's customers often invite my mother to dinner. I don't know how many calories these things have! Well, it's not true. After Da Chang Jin, my mother fell in love with Korean dramas. She watched them every night, and it was more than 10 o'clock every day. How could she get up early in the morning? Mom is late from work and has no time to exercise at all. How can I make mom thinner
first, I asked my mother to do aerobics, which is actually radio aerobics. My mother was panting after half of it. Next, I turned the hula hoop, and my mother took over the extra large hula hoop. I saw my mother kicking, bending, twisting neck, shaking hands, doing every action seriously. After a while, she was sweating all over. I quickly brought a towel and a water cup and said with concern, "OK, OK, that's all for today." Mother wiped the sweat and drank the whole glass of water, which was a relief
a week later, mom stood on the stage and said. She exclaimed in surprise, "I've lost one kilogram!"“ yeah! Lose weight successfully I cheered
it turns out that as long as you can stick to it, you will succeed in losing weight<

I went to KFC today. As soon as we got in, the three members of our family immediately separated. Dad went to order meals, and mom and I went to find seats. I finally found a seat and sat down. Before my father came, I looked at the KFC store again: the hall was very spacious, the tables and chairs were neat and beautiful, the facilities were complete, the walls around were covered with children's cartoon pictures and KFC posters, there were cool drinks, crisp and burnt potato chips, fragrant hamburgers, big chicken legs with all kinds of color and fragrance, looking at the food on the pictures, My mouth watering“ It's ready to eat! " With my cheering, Dad came with a tray full of food. My father bought me a set meal for children. I looked in the plate. WOW! The children's set meal used to give away toys! A small and exquisite Kentucky Fried Chicken villain is turning the oil barrel, but every time he is not lucky, he always plunges into the barrel! Looking at his funny appearance, I couldn't help giggling“ Yangyang, if you're not hungry, we'll eat them all! " My mother deliberately teased me. She took a big bite of the hamburger. When I looked at it, I grabbed the big chicken leg with my left hand and the hamburger with my right hand, and ate it with a whimper. In a short time, a set of children's meal was "reimbursed" by me
when I walk out of KFC store, KFC's delicious food is still in my mouth. In my heart, I always think that there are many good things for us to learn abroad

today, because of the hot weather, my father took me to the river to play, and also brought a bottle of fish. When I came to the river, my father sat under a big tree to enjoy the cool. As for me, I was playing with water and catching fish in the river
suddenly, I saw a shrimp. I thought it was a fish, so I couldn't wait to cuddle it up. Unexpectedly, it ran away. I went after it again. I finally surrounded it with my hand and put it in the bottle. After a careful look, it turned out to be a shrimp. At this time, I like a vent of the ball, all of a sudden soft. I think: it's hard to catch it, or raise it up! Then, I caught some fish and put them in the bottle to accompany the shrimp
I carried the bottle forward triumphantly and accidentally stepped on a piece of moss on the stone. Just listen to "Dong", I am like a drowned chicken, covered with water. And the fish and shrimp in the bottle also took the opportunity to run away, leaving an empty bottle to soak in the water. I picked up the bottle and walked sullenly to the bank. It's really "if you can't steal a chicken, you'll lose the rice.". So I went home wet
usually, I am always at school and seldom have close contact with nature. I am very strange to many things in nature. I will have more contact with nature when I have the chance

at the end of the long road is a starry night sky
the long journey of the world is full of too many material temptations. I don't know how much of what I promised you hasn't come true
I don't want to let go, I don't want to let you go, I don't want to watch you walk out of my life
--- cheer's Gorgeous Adventure
I woke up this morning and clearly remembered that I had cheer's face in my dream. The whole dream is full of escape. Later, log stood in front of the window, took my hand and said to me, it's OK. Jump down. I am here. Your life is as important as mine. This sentence is still lingering in my mind until I wake up. I think I must miss her very much. Honey, come back
just finished watching a short film "looking for the golden age" is a documentary of Mr. Wang Xiaobo. In fact, it's boring. I've been tracing the writer's past for 27 minutes. What I'm probably interested in is that there are too many videos from Wang Xiaobo himself and his works. Talking about the origin of this short film, it's a little funny. I went to two bookstores today. When I was in the second bookstore, I watched it all afternoon, and I lost my waist. I'm ready to go. The staff said that they can give you free dishes. It's just a computer disk. Out of the mentality of being greedy for small and cheap things, I thought I had a computer at home anyway, so I went to see what disk it was. There are a lot of discs, and only one interesting one was found in the end. It's not in vain. I stood there with a sore back and read all afternoon. There are always gains<

half of the summer vacation has passed, and my homework has been finished. In the rest of my life, I wanted to have fun for a few days. However, my parents forced me to learn this and that. If I didn't want to, they would ask me if I was proud, and then they would teach me a lot of reasons for me. I really don't know what they thought
I get up in the morning and wash up first. Then, my mother didn't even give me the time to have breakfast, forcing me to do the Mathematical Olympiad homework. After finishing my homework, I should have lunch. After lunch, my mother didn't let me take a nap, so she asked me to write a composition. After that, I knew it was time to learn English online. I studied for three or four hours
after dinner, I went out for a walk and had to take a shower when I came back. Then my father urged me to go to bed early to welcome the new day
well, the day passed like this. At night, I lie in front of the bed, looking at the stars, blinking freely, thinking: what meaningful things have I done today? Not at all! I entered the dream, I dream of doing homework
the summer vacation I'm looking forward to is not like this! It's a combination of work and rest. It's very bright and sunny. It's not like before the exam, struggling in the sea of learning all day, suffering in the exercises, I don't want it< Perhaps in the eyes of parents, summer vacation is a prime time for learning, while in the eyes of primary school students, summer vacation is a time for relaxation
mom and Dad, please respect us. My summer vacation is up to me

one day in the summer vacation, accompanied by my father and mother, I walked into the gate of the gymnasium. I felt as if I was in a wonderful world: in front of the fountain, two pots of large roses were in full bloom, surrounded by hundreds of small roses. It was really a beautiful scene. The flowers in the East were white as snow, and the flowers in the West were golden as gold, Yellow and white, particularly pleasant fragrance, fountain side, but also full of elegant free and easy, gorgeous pretty rose, branches down, like a blushing girl. Still calm in reverie, I suddenly heard a "Du, come here soon". I was startled. It turned out that my mother was calling me. I ran over like the wind. My mother reported the summer vacation to me
