Virtual currency today

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 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. 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 January 8, 2021, the price of bitcoin exceeded $40000

warm tips: according to the notice and announcement issued by the people's Bank of China and other departments, virtual currency is not issued by the monetary authority, does not have legal compensation and mandatory monetary attributes, is not a real currency, does not have the same legal status as currency, and cannot and should not be used as currency in the market, Citizens' investment and transaction of virtual currency are not protected by law
the above explanation is for reference only. Before investing, it is recommended that you first understand the risks existing in the project, and clearly understand the investors, investment institutions, chain activity and other information of the project, rather than blindly investing or mistakenly entering the capital market

2. The value of virtual currency is reflected in "more people recognize it". At the beginning of any instry, there will be savage growth. Take bitcoin as an example, the peak price of bitcoin is close to $2W, and the current price is only about $6500
in the current situation, blockchain is not a mature technology. What the market values is the so-called prospect, and it will take time to improve and excavate it slowly. However, the collapse of virtual currency is just a return to its own value
in short, I think bitcoin will continue to grow slowly after falling below a certain price. The current slump is just that the funds attracted by the previous heat have discovered the characteristics of virtual currency (hacker attack, dealer trading, these two situations will probably only appear in the newly issued currency, which is determined by the characteristics of blockchain, in other words, Hackers may also attack bitcoin in the early stage, but the more people and nodes bitcoin enters, the lower the probability of this situation, and the more difficult it is to generate)
in addition, I think that a large number of people in China even don't know what bitcoin is, so they are ready to make a fortune with money.

3. In winter, don't come in, especially Shanzhai coin. 90% of the so-called good projects went crazy in June. Bitcoin, Ethereum and other real virtual currencies can be bought for speculation, which has gone crazy in the last half month.

4. Virtual currency has normal fluctuation, so it is unpredictable.

5. Green venture currency (GEC) is a kind of digital currency in the form of P2P. You can also understand it as virtual currency. Different from those who register to send money or subscribe to buy money in the past, this miner digs money free of charge after registration and then sells it. Now many platforms are imitating him, and the price has been rising. At present, you can get on the bus with the miner. You can earn at least 600 yuan a month.

7. In general, you can calculate the forces by considering the effect of the forces in two mutually perpendicular directions
if the object moves to the right on the horizontal table, the vertical direction is the balance force (because there is no acceleration in the vertical direction). If the pulling force is horizontal, the object in the vertical direction is subjected to two forces: gravity g and table supporting force n. according to the balance condition,
N-G = 0
n = g
and the table supporting force n is related to the pressure n on the table; It is a pair of forces and reactions. According to Newton's third law, n & # 39; = N = g

if the tensile force is proportional to the horizontal direction θ Then the object is subjected to three forces in the vertical direction: G, N and FY, so there are
FY + N-G = 0
n = g-fy
n & # 39= N = g-fy

I wish you progress!
