bitcoin does not rely on a specific monetary institution. 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 money circulation
the decentralized feature and algorithm of P2P can ensure that it is impossible to artificially control the value of bitcoin by mass manufacturing. 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

principle
starting from the essence of bitcoin, the essence of bitcoin is actually the special solution generated by a bunch of complex algorithms. A special solution is one of the finite solutions of a system of equations. Every particular solution can solve the equation and is unique. In the metaphor of banknotes, bitcoin is the number of the top word of a banknote. If you know the number of the top word on a banknote, you have the banknote
and the process of mining is to constantly seek the special solutions of the equations through huge amount of calculation. The equations are designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start. After completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to paste the address to others, and you can pay through the same client
after installing the bitcoin client, it will assign a private key and a public key. You need to back up the wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost
network bitcoin
Ethereum will open at $225.03 on July 22, 2019.
you can log in to foreign trading platforms and trade at the time specified by the platform.
Recently, bitcoin has been swiping the screen frequently. One reason is that the story of "making rich" of bitcoin is surprising. The other reason is that the rise and fall of bitcoin is too crazy. After entering 2021, bitcoin is in a rising trend. Although it has declined ring this period, it has always remained at a high level
12 years ago, Nakamoto, a Japanese American, created bitcoin. It is said that Nakamoto himself has never appeared, but the bitcoin he created is crazy. This year, the value of bitcoin hit new highs, first US $30000, then US $40000. On February 22, 2021, the value of a single bitcoin hit a record high, reaching US $58000 each
is it sure to make money by investing so much money in "mining"? The answer may disappoint you again. Bitcoin's "wealth making" is based on the price rise. Once bitcoin's price falls and it is no longer so valuable, investors may lose all of it
some experts have warned that the bitcoin market is the easiest to be manipulated, because bitcoin is mainly concentrated in the hands of some people, and a virtual currency is so expensive that it can not be separated from the hype of these few people. At the same time, there is no sound and mature regulatory mechanism for the bitcoin market in the world, so the risk of investing in bitcoin is great
therefore, for ordinary people, it is better to stay away from bitcoin and "mining", don't you think
now bitcoin bubble serious, may collapse, the market needs to be cautious. But unlike tulip, it will rise slowly after falling, rather than collapse
because the total amount of bitcoin is limited. Mining costs are getting higher and higher. It can also be preserved for a long time at a low cost. At the same time, about 40% of bitcoin is in the hands of a very small number of people, which can achieve high control
you need to judge its future & quot; Collection value & quot; Up or down
what you should pay attention to is its & lt; Collection value & quot; It does not depend on itself, but on the public's enthusiasm for it and its general recognition. It's changing all the time
from the perspective of coin holders, the more people they buy, the better. This will lead to the & lt; decline of bitcoin; Collection value & quot; Up
there are many coin holders who strongly advocate bitcoin and turn shit into gold. With the success of advocacy, more and more people buy money. Excrement really becomes gold. Advocacy is no longer advocacy, but truth. This paradox is also what Soros said; Reflexivity Principle & quot; It's the embodiment of the idea. This is also the most painful and unacceptable thing for rational people who do not speculate
at present, I personally feel that the price is too high. There are too many speculators in the short term. There are some bubbles. Investment should be cautious. You can buy some in the next slump and collect them for a long time
you should not believe the following two statements:
1. Bitcoin is the perfect currency in circulation in the future. It has high use value, so it is very valuable
2. Bitcoin is deceptive and has no use value, so it is not valuable
one answer is that bitcoin is like a diamond. It does
diamond's & lt; Use value & quot Love is eternal), which was hyped by De Beers in the last century. Until then, diamonds were not worth money. And the total supply of diamonds is monopolized and controlled by giants such as De Beers Is "diamond" the most wonderful marketing scam in the world in the 20th century? Is it really worthless? There are many good answers to this question.)
De Beers constantly claims that diamonds are the strongest objects and can symbolize eternity. People graally accepted it
and Nakamoto develops bitcoin, and believes that its decentralization, blockchain technology and other characteristics are suitable for the future as a perfect e-currency (the initial title of the paper is "a peer-to-peer e-cash system"). With the expansion and publicity of bitcoin's followers, more and more people have accepted this idea. But now there are still a large number of people who don't know anything and feel that the price is rising sharply, so they buy bitcoin. After buying it, reverse rationalize it and persuade yourself to accept the concept that bitcoin is a perfect electronic currency
this is & lt; The community of imagination; The process of formation. The essence is similar. It doesn't matter whether these concepts are true or not. It's important: how many people do you trust. If more people believe in it, it will come true
In the end, diamond has become an extremely successful marketing case. The symbolic meaning of diamonds has been formed all over the world; The community of imagination;. Instead of collapsing like tulip, it has become a sustainable instryfrom the current trend, bitcoin is working in this direction. There is a public opinion game between advocates and bearers to see who has more power to influence the huge group of passers-by to identify or not to identify with bitcoin. Both sides exaggerate, saying that bitcoin is the Holy Grail of changing human society and that bitcoin is a Ponzi scheme. At present, because of the continuous rise (and it has doubled after several sharp falls), the advocates have the upper hand
