Dark bitcoin
bitcoin is just a game. If it is promoted as a tool to get rich, it can be regarded as a fraud. Just like the currency in other online games, the only difference is that bitcoin has been standardized since the game was first formulated. It can't be issued indiscriminately, so it can keep its value better than other virtual game props. It is equivalent to the online collection. Bitcoin is a prop in the game, and its value is reflected in the recognition of bitcoin by players: more people play, the value of props in the game is higher; The risk is that he is not the only game, and his algorithm is not the only one. Maybe someone will be able to make other special coins soon. All you need to do is promote the game and sell your props. As for money, bitcoin does not have the basic attributes of money, such as unfair initial distribution and insecure circulation. Money needs to be maintained by the state machine
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, the open source software and the P2P network on it were designed and released. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system. Unlike most currencies, bitcoin does not rely on specific currency institutions to issue. It is generated by a large number of calculations based on specific algorithms. 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 nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
1. Bitcoin (bitcoin) is a kind of network virtual currency, which can buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals
2. On January 7, 2014, Taobao announced that it would ban the sale of Internet virtual currencies such as bitcoin and lightcoin from January 14. On February 26, 2014, Democratic Senator Joe Manchin of West Virginia issued an open letter to a number of regulatory authorities of the federal government of the United States, hoping that relevant institutions would pay attention to the status quo of bitcoin encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency
3. On May 12, 2017, a global outbreak of bitcoin virus madly attacked public and commercial systems! Nearly 74 countries in the world have been seriously attacked
4. From August 1, 2017, global bitcoin trading platform will suspend recharge and withdrawal services. Bitcoin China digital asset trading platform will stop new user registration on September 14, and all trading businesses will be stopped on September 30

Bitcoin, English name bitcoin, is a digital currency based on blockchain technology, which is composed of a series of computer-generated complex codes. Like RMB's ￥ and US dollar's $, bitcoin has its own symbol, the "B" in the figure below
The inventor of
bitcoin is Nakamoto. Satoshi Nakamoto is the creator of bitcoin protocol and its related software bitcoin QT. In 2008, he published a paper called "bitcoin: a peer-to-peer electronic cash system", describing an electronic currency and its algorithm that he called "bitcoin"
In 2009, he released the first bitcoin software and officially launched the bitcoin financial system In 2010, he graally faded out and handed over the project to other members of the bitcoin communityNakamoto is believed to hold about one million bitcoins. If the price of each bitcoin was $2W, it was worth $20 billion at one time. So far, his true identity is still unknown to the outside world, that is to say, no one knows who Nakamoto is
bitcoin appeared after the global financial crisis in 2008. In fact, before that, many people have tried electronic currency, digital currency and virtual currency, but they have not succeeded. There are not only technical reasons, but also social environment and economic background reasons. To some extent, it was the 2008 financial crisis that gave birth to bitcoin
Calculation formula: ft = {MV
F is the average force, t is the time, M is the mass of the object, V is the velocity, and} is the variation; This formula is understood as that the impact force and its time acting on the object are equal to the change of momentum of the object
impact force refers to the force that appears when objects collide with each other. In the process of collision or striking, the force that suddenly increases and then rapidly disappears between objects is also called impact force or impact force. The characteristic of the impact force is that the action time is very short, but the magnitude can be very large. "
The impact force of this fluid is e to the continuous interaction between the fluid (such as water) and the object, resulting in impact force. The difficulty lies in the selection of research object and research process
extended data
usually, the solution of this kind of problem should focus on two points:
(1) using the "infinitesimal method" to determine the research object and research process: because the fluid is continuously interacting with the object, we can select a short period of time Δ T to determine the object. As mentioned above: in Δ T time, our research object is actually in the figure Δ Water in part X
what is the quality of this part of water Δ m= ρ S′v Δ T -- because the time is very short, the speed of water rising for a short distance can be regarded as constant; In addition, it should be noted that when the water reaches this position, the cross-sectional area becomes s ′, and s ′ is unknown. Because the water is continuous, combined with the first question,
Δ m= ρ S′v Δ t＝ ρ SVo Δ T
(2) ignoring the gravity of water. When using the micro element method to deal with the problem, the gravity and the impact force can be compared slightly< br />
investment risk is great
it is basically a black market transaction
not advocated by the state
at the same time, there is no way to ban it.
I think the vast majority of bitcoin's 800 million yuan should have gone into the pockets of some capitalists, and the remaining few went into the hands of those investors who speculated correctly in my opinion, bitcoin is more like a bubble economy. It is a game between capitalists and capitalists. Because even if the bubble breaks, they have plenty of means to come out, but for us, these small shareholders are different. p> Therefore, as users, we still need to be more rational to look at these things. The sky won't drop pie for us to pick up. We still need to focus on the present. We can't always look down on those castles in the air< the most important thing is to do what you do now
bitcoin has a wider audience and higher popularity. Dark coin is a supplement to bitcoin. Dark coin focuses on anonymity, which is a supplement to the anonymity of bitcoin. Although bitcoin also has the characteristics of anonymity, some studies have found that the anonymity of bitcoin can be found by some means. Dark coins are different. By far, dark coins have the best anonymity
the main supporters of dark money are geeks and hackers, which can also be said to be hacker money. The user group is very limited, and it can not be accepted by the mainstream group
some of the features previously publicized by bitcoin have graally been proved to be features in a certain stage. Bitcoin is integrating into our daily life and is recognized as a subversive technology, especially blockchain technology.
that is to say, it depends on its speculative value. No matter how high or low its value is, it doesn't matter. What matters is that there is such a group of people in the world speculating on it! Just make sure you're not the last to take over. We should pay attention to the following points: 1. Entry time. The later the entry time, the greater the risk; 2. Entry price, relative to its price, if you want to enter the price has been too many times its own premium, then I suggest you consider it more. Don't use black coins to compare with bitcoin. Although both are virtual currencies, they can't be compared with each other.
