Hackers' favorite virtual currency
1. Complete decentralization, without issuing institutions, it is impossible to manipulate the number of issues. Its distribution and circulation are realized through open-source P2P algorithm
2. Anonymity, tax exemption and supervision free
3. Robustness. Bitcoin is completely dependent on P2P network and has no distribution center, so it cannot be shut down externally. Bitcoin price may fluctuate and collapse, and many governments may declare it illegal, but bitcoin and its huge P2P network will not disappear
4. Borderless and cross-border. Cross border remittance will go through layers of exchange control agencies, and the transaction records will be recorded by many parties. But if you trade with bitcoin, enter the digital address directly, click the mouse and wait for the P2P network to confirm the transaction, a lot of money will pass. It does not go through any regulatory agencies and will not leave any cross-border transaction records
5. It is difficult for the cat to survive. Because bitcoin algorithm is completely open source, anyone can download the source code, modify some parameters, recompile, and create a new P2P currency. But these counterfeit currencies are fragile and vulnerable to 51% attacks. Any indivial or organization, as long as it controls 51% of the computing power of a P2P currency network, can manipulate transactions and currency value at will, which will be a devastating blow to P2P currency. Many Shanzhai coins die in this link. The bitcoin network is robust enough. If you want to control 51% of the computing power of the bitcoin network, the number of CPUs / GPUs required will be astronomical.
on November 1, 2008, the hermit named "Nakamoto Tsung" watched the sky at night. Seeing that the time was ripe, he announced his new idea of issuing an electronic currency called "bitcoin" on a secret cryptography forum
then, in 2009, bitcoin was born
for a while, there were rumors all over the world:
"what is bitcoin?"
"what's the magic power of bitcoin?"
"can it compare with traditional currency?"
it's just a hermit's "masterpiece left behind". Why did it make such a big stir in the world<
it turns out that this bitcoin has risked the world's great injustice, escaped the high-ranking government control, and set up a "small autonomy" on its own:
bitcoin no longer needs to be issued by a specific institution, but is generated through a set of "institutions" designed by Nakamoto Tsung, which is based on a specific algorithm and through a large number of calculations. Regardless of the world, as long as you have a computer, access system, and operate the "organ", you can become a "coin digger"
a thousand waves were aroused for a while, and an undercurrent was set off in the river and Lake: men, women, old and young were yearning to invest in the "money digging fever"<

but since ancient times, unique martial arts skills have come out, and most of the onlookers will see through them, but fengmaolingjiao is the one who really understands the mystery
in the same way, this "coin digger" who creates miracles is not something ordinary people can do at will. Even if everyone has a computer and computing tools, it depends on talent and hard work to generate a new bitcoin
if every "digger" wants to dig bitcoin, he has to go into many "mechanisms" of Nakamoto Tsung and use computers to solve a complex mathematical problem through huge calculation. This is far from enough. Whether we can understand the secret is not only related to the ability of the "coin digger", because the "mechanism" will automatically adjust the difficulty of the questions, so that the whole system will get a qualified answer every 10 minutes, while the vast army of "coin diggers" are crazy computing. Who can understand the secret depends on the nature
it's like buying lottery tickets. Everyone is crazy to generate various combinations of numbers with computing tools in hand. Whoever can guess the same string as the big prize will be the winner
in the end, the lucky person who was lucky enough to get a specific solution successfully created a bitcoin, and the reward for him was a total of 50 bitcoins
at this time, someone will ask, is bitcoin hard to get out of the endless mining
this is the true wisdom of Nakamoto's seclusion
like all kinds of gold, silver, iron and copper veins, bitcoin will be g out one day. A total of 21 million mathematical problems have been designed in the "mechanism" and 21 million corresponding qualified answers have been matched. In other words, the upper limit of bitcoin mining is controlled at 21 million
Where is the mystery
we know that the reason why the government calls the wind and the rain is precisely because it has the power to issue currency. Increasing and recing issuance are "fierce moves" to regulate the economy
and Nakamoto's restriction on the total amount of bitcoin has cut off the way for bitcoin market to be regulated, which is obviously the opposite
which is better? There are two schools in the world:
"supporters" think that eliminating intervention is a sign of social progress
the "losers" feel that fixed aggregate may lead to deflation, which in turn will lead to a series of market weakness and "bone breaking" of the overall economy
the merits and demerits will be left to future generations
since there is a reward for digging coins and the total amount is limited, isn't the mine going to be g through in just a few days
How could the "mechanism" that he had painstakingly researched be easily manipulated by the world<
Nakamoto has two rules under the "agency" neutrality:
first, the more bitcoin, the less reward
- when the total amount reaches 10.5 million hours (50% of 21 million), the reward will be halved to 25. When the total amount reached 15.75 million (5.25 million new output, or 50% of 1050), the bounty was further halved to 12.5. And so on
secondly, the more the total number of "coin diggers", the lower the efficiency
in this way, bitcoin will be proced more slowly in the later stage. According to the plan, from the birth of bitcoin in 2009, mining will last more than 100 years, and it will not reach the upper limit until 2140
today, the total amount of bitcoin mined out in the world is just over 16 million
all of the above are just a set of "mechanisms" carefully arranged by master Nakamoto. There is another set of "mechanisms" with such precision
bitcoin is a rare thing in the world, so how to trade it? How to manage
after living in seclusion for many years, Nakamoto studied cryptography, a unique security process for bitcoin circulation
the transaction behind bitcoin is very complicated. Bitcoin can generate bitcoin addresses randomly, and each address has a corresponding private key, which is equivalent to the bank card number and the corresponding password. Only when you have both can you manage your money
but is the complexity of this address comparable to that of ordinary bank cards
how confidential is the bitcoin address
each address is made up of a string of letters and numbers about 33 bits long, always starting with 1 or 3
how many such random addresses are there? The answer is: probably more than the sand on earth
it's not easy to break such a complex "secret protection system"
in this way, with the second "organ" blessing of Nakamoto Tsung, bitcoin circulation has more security than ordinary currency
it's no wonder that with the advent of bitcoin, the currency world is shaking, and a new fight is in the dark
bitcoin, like countless secret lone Rangers, grows savagely under the authority of the government. According to the legend, bitcoin is free (decentralized, tax-free, regulatory free), strong (relying on P2P network, external can not be closed), omnipresent (cross-border, borderless), and anonymous
you can understand, "freedom", "coming and going without name" and "omnipresent", which means that bitcoin can not only be tracked and supervised by the government, but also grow wildly in the world. It's a great way for hackers to blackmail
moreover, since last year, bitcoin has been rising wildly, and hackers all over the Internet know this information well
there is no doubt that bitcoin is a safe and profitable way to blackmail

or like this< But all the martial arts in the world are strong. Bitcoin also has weaknesses
there are three pithy formulas:
first, bitcoin network is not broken, and trading platform is fragile
Second, the "black market" trading, speculation rampant, price roller coaster day by day
thirdly, it is difficult for ordinary people to understand the secrets of nature because of their profound martial arts
in particular, the third point is that although the Kung Fu is good, the threshold is too high, which is lamentable
then, if you look at China today, where is bitcoin going
to be fair, in the eyes of the mother of the central bank, it is not too much to say that bitcoin is a barbaric growth: in the past year, with the devaluation of RMB, bitcoin has once again become the target of investors' speculation, and its value has increased by 120%
smart passers-by have already seen through everything

coupled with the emerging bitcoin virus, it seems that it is time for bitcoin to be subject to a wave of regulation.
as we all know, the "blackmail virus" is rampant all over the world, and hackers ask the "victims" who are recruited to pay bitcoin. According to the data, the price of bitcoin has skyrocketed by 2.21 million times in the past eight years
for the rise of bitcoin price, the Chinese people must have made their own contribution. After all, bitcoin trading in China once accounted for more than 80% of the global trading volume
However, according to the latest data from the research department of fire coin, Japan accounted for 46.4% of the global bitcoin trading volume last week, followed by the United States, accounting for 26.4%, China ranked third, and the trading volume dropped to 10%. Therefore, if the price of bitcoin exceeds 10000 yuan recently, the contribution of Chinese people should be very smallbitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items.
in fact, the generation of virtual currency also needs professional development team to develop, and cannot be developed and generated by itself. The development technology of virtual currency is mature, and there is no technical difficulty, but the positioning of virtual currency is the biggest problem, and the generation of virtual currency needs a lot of hardware equipment to mine
it is not a general equivalent, but an expression of value relevance, or a symbol, or a kind of personalized currency. On the other hand, it can also be called information currency. What they have in common is that they are all symbols of uncertain value and relative value. In this case, the traditional meaning of money has been broken. Money in the original sense is only a special case of a new and broader currency. Money can be regarded not only as a general equivalent, but also as a group of symbols of relative value strong>

Green means: & quot; Come on! I'm willing to fall in love and pursue it boldly& quot; Yellow means: & quot; There are opportunities. If it suits me, there is still a chance of success& quot; Red indicates: & quot; At present, I don't want to fall in love, don't pursue me& quot; The brave young man will pursue boldly according to the other party's clothing color and his own choice, and will never be labeled as misbehaving
once the relationship is established, the man will give the woman an engagement ring and hold a ceremony. This custom is found all over England. Wedding or engagement ring is a traditional custom of many nationalities. When the English hold a wedding ceremony in the church, it is indispensable for the bridegroom to wear a ring for the bride.

It symbolizes the husband's pure love for his wife. At the same time, the wife also expresses that she accepts and is faithful to this kind of love
the custom of wearing rings can be traced back to ancient Egypt and China. It is not only a keepsake but also an ornament. At first, the wedding ring is not inlaid with diamond, emerald, ruby and sapphire. The pure circle symbolizes the reunion of two people who are married together.

British people need to wear formal dress when they get married; The bride wears a white shirt, a white skirt, a white wreath, a long white veil and a white bouquet. In short, the British advocate white, which symbolizes the purity and good luck of love. The custom of wearing headdress can be traced back to the 10th century B.C., when women wearing headdress was popular in the two river valley. In ancient Greece, when a wedding ceremony was held, not only the bride wore a linen or wool veil, but also a couple wore a corolla. In Roman times, people of different religious beliefs had to wear different colored headdresses to show their differences. After the middle ages, the crown decorated with pearls appeared among the nobles. Later, it developed into a white veil, and the size of the veil was extended day by day, and spread all over Europe

Accompanied by the male guests, the bridegroom in full dress stands at the altar waiting for the bride. When someone dies in an English family, a small notice is often published in the newspaper. After seeing the notice, relatives and friends go to the funeral to show their respect for the dead and greetings to their families
once the wedding ceremony is held, when the bride and groom come out of the church, people should congratulate the new couple. This kind of congratulations is not kissing, hugging and shaking hands, but scattering colorful scraps of paper on them. The custom of scattering paper scraps originated from scattering wheat grains. In 1491, King Henry VII of England traveled to Bristol with his queen. During the journey, she was seen by a baker's wife, so she sprinkled wheat grains on them from the window and cried out: & quot; Welcome, your majesty! I wish you happiness and longevity& quot; By the 16th century, this custom had been widely spread. People sprinkled wheat grains on the bridegroom and bride, and sometimes dyed various colors.

The first year is paper marriage, the second year is cotton marriage, the third year is leather marriage, the fourth year is Yi marriage, the fifth year is wood marriage, the sixth year is iron marriage, the seventh year is bronze marriage, the eighth year is pottery marriage, the ninth year is willow marriage, the tenth year is tin marriage, and then there are steel marriage, Raoren marriage, lace marriage, ivory marriage and crystal marriage. Since the 15th year, there has been a title every five years, which is enamel marriage, silver marriage (the 25th year is a big ceremony), pearl marriage, coral marriage, ruby marriage, sapphire marriage, gold marriage (the second big ceremony in the 50th year), jade marriage and diamond marriage. This last one is the third big celebration, but few people can celebrate it
business etiquette

recently, blackmail virus has swept the world, and hackers only choose bitcoin as the way to pay ransom. The reason why hackers love bitcoin is very simple. We can understand the properties and characteristics of bitcoin
the current price of bitcoin and the previous increase are also full of temptation for hackers. After all, the current price of bitcoin has exceeded the price of gold
in this virus incident, another focus of market attention comes from bitcoin, the target of blackmail by hackers. In the view of instry insiders, the reason why bitcoin is required to be paid is that bitcoin is still lack of effective supervision at present, thus providing the convenience of "exemption from review" when criminals obtain illegal benefits
