Digital currency in live broadcasting room
We need to call the police. This belongs to currency fraud. We can't blindly trust the virtual investment platform that can easily earn a lot of money. Fraud gangs often use "small investment, big income" as t to let investors taste the sweetness first and then increase investment, so as to achieve the purpose of fraud
at present, the so-called "digital currency" in the market is not legal digital currency. The so-called "digital currency" launched by some institutions and enterprises and the so-called promotion of the central bank's issuance of digital currency may involve pyramid selling and fraud. It is necessary for the general public to raise their risk awareness, invest rationally and prudently, and prevent the interests from being damaged
extended information:
five ways to distinguish whether digital currency is MLM currency. virtual currency does not rely on specific monetary institutions to issue, it is based on a specific algorithm, generated through a large number of calculations, is a decentralized way of issuing. Each different terminal node is responsible for maintaining the same account book, and the maintenance process is mainly to package and encrypt the transaction information by the algorithm, while the MLM currency is mainly issued by a certain organization, and the profit is made by pulling the head
2. Transaction mode. Virtual currency is a kind of sporadic transaction formed spontaneously in the market. After the scale is formed, the third party graally establishes an exchange to complete the transaction. The MLM currency is issued by an institution and traded on its own platform
3. The virtual currency itself is an open source program, maintained in the GitHub community. The parameters and methods of the total amount limit are shown in the open source code. The open source of MLM currency is completely ing other people's open source code, and there is no use of open source code to build programs, so its essence is controlled by the website like Q currency
Whether the source code link is given. The general decentralized digital currency will give the source code link in the prominent position of the official website, so as to show the operation mechanism of the monetary system openly and transparently. What MLM currency focuses on is the transaction process of recharge purchase, not to mention its operation mechanism, and even the website does not have the link address of the source code5. Whether the official website starts with HTTPS. In general, the addresses of the official website and trading website of decentralized digital currency begin with HTTPS. The purpose of this kind of website is to protect users' data from illegal theft. But the official website of MLM currency, trading website and other related websites do not start with HTTPS
It's illegal
First, digital currency ICO is illegal in China.
in September 2017, the people's Bank of China issued an announcement on preventing the financing risk of token issuance, which formally determined that ICO is illegal financing without approval, and no organization or indivial is allowed to participate
later, it was announced on April 23, 2018 that the left and right digital currency ICO platforms had all withdrawn from the Chinese market, so the current ICO is illegal in China
Second, digital currency exchange is prohibited in China.
after announcing that ICO is an illegal financing activity, the central bank also listed services such as trading, exchange, pricing and information intermediary for virtual currency as prohibited items, which means that digital currency exchange is illegal in China
all trading platforms, including bitcoin China, okcion and fire coin, announced in 2018 that they would stop the RMB recharge business and graally shut down their trading platforms. As of April 2018, all digital currency exchanges had completely withdrawn from the Chinese market
digital currency generally has a special digital currency exchange. We can buy the digital currency we need in our digital currency exchange
we can buy from our friends in addition to the exchange. If a friend has something, you can discuss and ask if he can sell it to you
we can buy our digital currency from traders nearby if we need more
we accept payment by digital currency payment service. If we open a physical store, we can support payment by digital currency, so we can also get our digital currency
finally, we can get digital currency by mining, and we can get digital currency by equipping mining machine to work mining, such as investing more hardware
digital currency trading: it can be traded only after RMB or digital currency is recharged in a third-party digital currency exchange
purchase of digital currency: no matter how many coins you buy, there is no limit. For example, if bitcoin is 100000 yuan, you can buy 0.0001, and there is no limit on how many coins you can buy or sell
digital currency trading time: 365 days a year, 24 hours a day, can be traded
coinbase transaction is a special transaction that generates bitcoin "out of thin air". Only miners can write this kind of transaction, and the number of generated bitcoin is limited by rules (new currency reced by half for every 210000 blocks + transaction fee for this block)
however, the rules do not stipulate that the miner must take away all the rewards that can be taken, and can choose not to take them
therefore, a mine pool connected with the RSK side chain has made a bug before, forgetting to take away the reward and occupying a pit in a block for nothing, which is equivalent to destroying the corresponding amount of bitcoin, making the total amount of bitcoin decrease a little bit permanently
in addition, to spend a bitcoin, you only need to specify the transaction ID and output serial number
as like as two peas in multiple blocks repeatedly write identical coinbase transactions, the transaction ID is also repeated.
therefore, this kind of situation also occupies the pit of a block in vain, and permanently destroys the corresponding amount of bitcoin
it seems to me that this is still a security vulnerability, so the new version of bitcoin software later banned the writing of repeated coinbase transactions. But until now, there has been no ban on miners not getting their e rewards
generally speaking, a coin is controlled by a private key. If a coin is transferred to an address where no one knows the private key, it will be destroyed
if the owner does a good job in security, and the private key is not disclosed and cannot be guessed, but he accidentally loses the private key, it is equivalent to destroying all the coins he owns
there are only some special circumstances that require intentional destruction of coins
one is irreversibly converted into another kind of currency, such as the contract currency XCP attached to bitcoin and wormhole cash WHC attached to BCH
the second is to save certificates and data on the chain, such as the time stamp: panbiao.com/2013/08 /
and the crowd funding of the original Ethereum founding team: zhuanlan.hu.com/p/29
the private key is essentially a big number. Whoever knows this number can control the currency on the corresponding address. So the private key must be generated with reliable random number, otherwise it may be guessed and stolen
compared with the token, the address is the hash of the public key. There is no way to judge whether an address has a corresponding public key and private key (even if the public key is known, the corresponding private key cannot be known). Therefore, even if it is explicitly the address of "burned" token, the system does not prohibit the transfer in
strictly speaking, what locks the currency is a small program (script). This program takes the input as the public key and digital signature. First, check whether the public key hash is consistent, and then check whether the digital signature is valid. If it is valid, it will be verified and transfer is allowed; Otherwise, it will be judged that the transaction is illegal and refuse to package into the chain
it is the whole node software that explains and executes this program. It can be said that the software code of the whole node specifically defines a coin
however, the current situation is very embarrassing. Most miners do not run the whole node, only a few mines are running. The vast majority of users do not run the whole node, even if they run the whole node, they can only perform verification, no computing power, no block.
According to the statistical data, by the end of 2019, there are 160 million stock investors in China, of which indivials account for 99.76%. This shows that most shareholders are very confident. Although they know the 28 law of the stock market, that is, 80% of investors lose money and only 20% of investors can make money, almost everyone thinks that they belong to that 20%{ RRRRR}
in fact, whether it's online live stock analysts or those books that teach people to speculate in stocks, I think it can only be used as a reference, operating completely according to the analysts' words and the things in the books, or even as blind as those who can accurately predict the trend of the capital market, and making money directly through the capital market transactions
is there a real master? There must be. Unfortunately, Xiaobian has never met these real experts. They don't recommend stocks to others at all, and they don't have time to write books. They all analyze and operate on their own and make money on their own. So, for those who actively recommend stocks to you on the Internet, just refuse it, so as to avoid endless trouble
