❶ How much is a bitcoin now

The concept of bitcoin (Bitcoin) was originally proposed by Satoshi Nakamoto on November 1, 2008, and was officially born on January 3, 2009. The open source software designed and released according to the ideas of Satoshi Nakamoto and the P2P network built on it. Bitcoin is a virtual encrypted digital currency in the form of P2P. Peer-to-peer transmission means a decentralized payment system. Unlike all currencies, Bitcoin is not issued by a specific currency institution. It is generated by a large number of calculations based on a specific algorithm. The Bitcoin economy uses a distributed database composed of many nodes in the entire P2P network to confirm and record all transactions. And use the design of cryptography to ensure the security of all aspects of currency circulation. The decentralized nature of P2P and the algorithm itself can ensure that the value of the currency cannot be artificially manipulated by mass-producing Bitcoin. The cryptography-based design allows Bitcoin to be transferred or paid only by the true owner. This also ensures the anonymity of currency ownership and circulation transactions. The biggest difference between Bitcoin and other virtual currencies is that its total amount is very limited and it has a strong scarcity. On January 8, 2021, the price of Bitcoin exceeded $40,000.

Warm reminder: According to the notices and announcements 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 currency attributes, and is not currency in the true sense. It does not have the same legal status as currency, cannot and should not be used as currency in the market, and citizens’ investment and trading 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 of the project, and have a clear understanding of the project’s investors, investment institutions, on-chain activity and other information, rather than blind investment or mistaken entry Funding disk.
Investors should not substitute such information for their independent judgment or make decisions only based on such information, which does not constitute any investment operation.

❷ How to trade domestic bitcoins

There are two types of bitcoin transactions, one is spot trading on a centralized trading platform, and the other is trading on a decentralized trading platform.

1. Centralized exchanges are similar to stock market transactions, pending orders, real-time transactions, and can refer to several well-known trading platforms with the largest trading volume in the world, Huobi OKEX Binance

2. Decentralized exchanges, through direct transfers between wallets, not through the platform side to receive and pay, similar to the platform side to match transactions, disadvantages: no pending order transactions, slow transaction

❸ Is Bitcoin a big scam?

Bitcoin is a scam, so you must be cautious when investing and managing your finances.

Even if it is gold, which is called “hard currency”, the price of gold will not only go up and down. Gold itself does not have a bubble, but if the price is too high, there will be a bubble, and the bubble will eventually burst, and the same is true of virtual currencies such as Bitcoin. The more common virtual currencies, the closer the value of Bitcoin is to zero.

This kind of currency with purely digital symbols has no asset backing, no financial receipts and payments, no cash reserves, and no use value. It is only a circulation symbol. Once it loses its credit guarantee, it is A pile of beautifully printed waste paper. Investors should be alert that there is no so-called safe investment in this world, and all investments are risky.

The People’s Bank of China and other departments have issued documents to strictly rectify the above-mentioned behaviors, clarifying that token transactions are not protected by law. In the face of continuous innovation, government departments should continue to upgrade their supervision methods and capabilities on the basis of continued strict supervision, and continue to increase publicity and crackdowns to prevent the masses from being deceived.

Investing in virtual currency is more of a speculative behavior, and investors should strengthen risk prevention Awareness and identification ability, do not involve money transactions without confirming the identity of the other party, do not believe in low-risk, high-return investment products, especially do not join unverified investment and wealth management groups at will, these are often carefully planned by telecommunication network fraudsters. Designed snares.

It is best to buy investment and financial management accompanied by children, and to learn from official and authoritative channels, and report to the police in time when you find that you have been deceived. Properly protect various account passwords, identity information, etc., and do not easily tell others. Anyone who mentions the need for transfer or remittance should be highly vigilant and consult with trusted acquaintances.

❹ One Bitcoin can be exchanged for 50,000 RMB, and what is the current situation of those who bought 100,000 Bitcoins that year

We often hear people make fun of: money is not everything, and no money is everything. It is undeniable that this is a fact. Some people will choose to work hard and save some money to save money. Some people will take risks to invest in business, and some people will think about relying on financial management and using money to make money to make more money. There are many ways to manage money, such as buying stocks, buying funds, or buying “Bitcoin”.

Then some people began to ask, how could an ordinary English teacher be so insightful that he caught the dark horse of Bitcoin? In fact, many of Li Xiao’s friends were investing in virtual currency at that time, so Li Xiao also had a little understanding of this. At that time, Li Xiao thought that Bitcoin would have room for appreciation, but he didn’t expect that the value of Bitcoin would actually turn over to Thousands of times, the bitcoins in his hand gradually accumulated from the initial 2,100 to 100,000. Because of the 100,000 bitcoins in his hand, he became a rich man with a net worth of 7 billion.

Li Xiao, who has so much wealth, can enjoy life directly without any further effort, but Li Xiao did not do that. He is grateful for everything he has received and begins to give back to the society. He stopped to do charity activities and helped many poor farmers. Now, he has started his own business, and at the same time, he has not given up his specialties and hobbies – publishing books. Li Xiao’s experience along the way is like this story, And we will also wish this kind protagonist to be lucky all the time.

❺ How Bitcoin newbies operate

4 common trading forms of Bitcoin: spot, futures, options, ETF

1. Spot trading
Spot trading is almost the same as stock trading, buy low and sell high to earn the difference! However, Bitcoin is a T+0 model, which can be bought and sold anytime, anywhere, and there are no restrictions on opening and closing, trading suspension, etc., and it is open for trading 365 days a year.

2. Futures trading
Futures are often referred to as contract trading. I believe most people cannot refuse the temptation of contracts. Contracts can be long and short, and leverage can also be opened, with a maximum support of 100 times, which indirectly magnifies the benefits and risks by 100 times, because human nature is inherently greedy. However, the difficulty factor of making money from contracts is high. Because Bitcoin fluctuates greatly, it may hit a liquidation in an instant, so futures trading should be involved with caution.

3. Option trading
The nature of option trading is the same as that of spot.
Since options and spot properties are the same, what is the difference between the two? A simple comparison:
For example, BitOffer’s world’s first Bitcoin option has no margin, no handling fee, and no exercise!

(The only option in the world without exercise)

1. Spot, buy a bitcoin for $7,500
2. Option, buy a bitcoin option It takes 5 dollars

Bitcoin rises from 7500 to 8000 dollars, the spot earns 500 dollars, and the options earn 500 dollars.
The benefits of the two are the same, but the cost is 1500 times different.
This is the case with options. It is the same as calculating profit margins from spot, except that you don’t need to pay the full amount, you only need to pay a little deposit. (Different from traditional European options)

4. ETF fund trading
ETF is usually called an exchange-traded open-end index fund, which is a very popular financial derivative in the traditional financial market , BitOffer launched the Bitcoin ETF fund, which added a fixed leverage on the original basis, because the back of the product corresponds to a certain number of futures contract positions.
Bitcoin ETF is linked to the Bitcoin index, so what is the difference with the spot?

1. This year’s bitcoin production will be reduced, theoretically X2
2. Mining machines should be updated, theoretically X2
3. The current price of bitcoin is 7500X4=30,000 US dollars (production reduction next year) Expected price later)

During this period, the return comparison between holding spot and ETF funds:
1. Buying spot and holding, earning 3 times
2. Buying ETF funds , up to more than 15 times (fund compound interest calculation)
There is no doubt that Bitcoin ETF is the best investment choice!

❻ Can bitcoin be bought on the same day and sold on the same day?

According to the trading rules of the Shanghai and Shenzhen stock exchanges, the A shares of the two markets implement the T+1 system, and stocks bought on the same day cannot be sold on the same day It can only be sold on or after the second trading day. The B shares in the two cities implement the T+0 system, and the shares bought on the same day can be sold on the same day.

❼ How much is a bitcoin

Bitcoin is a virtual currency.��! So its exchange rate is not fixed! Every day changes! Just like stocks! Please make inquiries on the day!

❽ Is bitcoin investment allowed in China?

In China, the “Renminbi Management Regulations” stipulate that the production and sale of token tickets is prohibited. Since there is no clear judicial interpretation of the definition of token coupons, if bitcoin is included in the “token coupons”, the legal prospect of bitcoin in China will face uncertainty.

The current rapid rise in the price of Bitcoin has formed speculative expectations. If it is not stopped in advance, it will eventually form a bubble, bring huge losses to some investors and financial institutions, and destroy the stability of the financial system.

(8) Bitcoin to buy air tickets Extended reading :

Bitcoin does not have the function of a medium of exchange in China, so it cannot be called a currency. At the same time, Bitcoin has the function of storing value and has a certain investment value. However, the rapid rise of the current price has formed speculative expectations.

There may be a bubble in the future, so it is necessary to take measures in advance, which can also inhibit some illegal activities of money laundering and asset transfer through Bitcoin.

❾ How bitcoin is calculated

To understand the technical principles of bitcoin, you first need to understand two important cryptographic techniques: HASH code: convert a long string into a fixed The length of the string, and its conversion is irreversible, that is, it is impossible to guess the original string from the HASH code. SHA256 is mainly used in the bitcoin protocol.
Public key system: Corresponding to a public key and a private key, keep the private key in the application, and publish the public key. When A transmits information to B, it can use A’s private key to encrypt the information, and B can decrypt it with A’s public key, which ensures that a third party cannot pretend to send information from A; at the same time, when A transmits information to B, it uses B’s public key to decrypt it. The key is encrypted and sent to B, who then decrypts it with his own private key, which ensures that a third party cannot eavesdrop on the communication between the two. The most common public key system is RSA, but the bitcoin protocol uses the lliptic Curve Digital Signature Algorithm. What’s the difference between cash and bank accounts? bitcoin is electronic currency, and the unit is BTC. Also used in this article to refer to the entire bitcoin system. Like opening an account in a bank, the corresponding concept in bitcoin is an address. Everyone can have one or several bitcoin addresses, which are used to pay and receive money. Each address is a string starting with 1, such as I have two bitcoin accounts, and. A bitcoin account is uniquely determined by a pair of public key and private key. To save the account, you only need to save the private key file. Unlike bank accounts, banks will keep all transaction records and maintain the book balance of each account, while bitcoin transaction records are jointly maintained by the entire P2P network through a pre-agreed agreement. How much money is in my account address? Although software using bitcoin can see the current account balance, unlike a bank, there is no one place to maintain the book balance of each address. It can only calculate the account balance in real time through all historical transaction records. How do I pay? When I pay from address A to address B of the other party, the payment amount is e. At this time, both parties will announce the transaction information to each network node, telling address A to pay address B, and the payment amount is e. In order to prevent a third party from forging the transaction information, the transaction information will be encrypted with the private key of address A. At this time, the network node that receives the transaction information can use the public key of address A to verify that the transaction information is indeed sent by A. Of course, the trading software will do these things for us, we only need to enter the relevant parameters in the software. What will the network node do after receiving the transaction information? This is the most important part of the entire bitcoin system and needs to be elaborated. For the sake of simplicity, only the currently implemented bitcoin protocol is used here. In the current version, each network node will save all transaction information through synchronization. All transaction information that has occurred in history is divided into two categories, one is “verified” transaction information, that is, the transaction information that has been verified, which is stored in a series of “blocks”. The information of each “block” is the ID of the previous “bock” (the ID of each block is the HASH code of the block’s HASH code) and the newly added transaction information (see an actual block). The other category refers to the transaction information that has not been “verified”, and the transaction information just paid above belongs to this category. When a network node receives new unverified transaction information (maybe more than one), since the node saves all the transaction information in history, it can calculate the book balance of each address at that time, so as to calculate the Whether the transaction information is valid, that is, whether there is sufficient balance in the payment account.�� After removing invalid transaction information, it first takes out the ID of the last “block”, then combines these unverified transaction information with the ID, plus a verification code to form a new “block”. “. The above construction of a new block requires a lot of computing work, because it needs to calculate the verification code, so that the above combination becomes a block, that is, the first few digits of the HASH code of the block’s HASH code are 1. Currently, the first 13 bits are required to be 1 (approximately, not sure about the specific method), which means that if the block is generated by the enumeration method, the average number of enumerations is 16^13 times. Using CPU resources to generate a block is called “gold mining”, because the production of the block will get a certain reward, and the reward information has been included in the block. When a network node generates a new block, it broadcasts it to other network nodes. However, this network block may not necessarily be accepted by the network, because there may be other network nodes that have produced blocks earlier, only the earliest block or the block with the most subsequent blocks is valid, and the remaining blocks are no longer used as the next block. the initial block. How does the other party confirm that the payment is successful? When the payment information is distributed to the network node, the network node starts to calculate whether the transaction is valid (that is, whether the account balance is sufficient to pay), and tries to generate blocks containing the transaction information. When a total of 6 blocks (1 direct block and 5 subsequent blocks) contain the transaction information, the transaction information is considered “verified”, so the transaction is officially confirmed, and the other party can confirm that the payment is successful. A possible problem is that if I pay the balance in address A to address B, and at the same time pay to address C, if only the single-bit transaction is verified, it is valid. At this point, my way of cheating is to generate 6 blocks containing only B and send them to B, and generate 6 blocks containing only C and send them to C before the truth is revealed. Since the CPU time I need to generate the block is very high, compared to the whole network, the probability of my success in cheating is very small. What is the motivation for network nodes to produce blocks? As can be seen from the above description, in order to make the transaction information valid, the network node needs to generate 1 and 5 subsequent blocks to contain the transaction information, and such block generation is very CPU-intensive. How to get other network nodes to help produce blocks as soon as possible? The answer is very simple. The protocol stipulates that the address that produces the block will be rewarded with BTC, and the transaction fee promised by both parties. At present, the reward for producing a block is 50BTC, and it will be halved every four years in the future. For example, between 2013 and 2016, the reward is 25BTC. Are transactions anonymous? Yes and no. All BITCOIN transactions are visible, we can check all transaction records of each account, such as mine. But unlike the banking monetary system, everyone’s account itself is anonymous, and everyone can open many accounts. Overall, the so-called anonymity is not as good as claimed. But there is another benefit of bitcoin for black market transactions, it cannot be frozen. Even if the police can trace a bitcoin address, there is no way to do it unless the computer used by the exchange is traced based on the network address. How to ensure that bitcoin does not depreciate? In general, the value of a currency is inversely proportional to the amount of currency issued when trading activity is comparable. Unlike traditional money markets, where the central bank can determine the amount of money to be issued, there is no central issuer in bitcoin. Only by producing blocks, a certain amount of BTC currency can be obtained. Therefore, the new increment of bitcoin currency is determined by: 1. The speed of block production: The bitcoin protocol stipulates that the difficulty of producing a block is fixed at an average of 2016 blocks every two weeks, and one block is produced in about 10 minutes. Moore’s Law, where CPU speeds double every 18 months, doesn’t speed up production blocks. 2. The number of rewards for producing blocks: Currently, each block produced is rewarded with 50 BTC, which is halved every four years. In 2013, the reward amount was 25 BTC, and in 2017, the reward amount was 12.5 BTC. Combining the above two factors, the speed of bitcoin currency issuance is not controlled by any single node in the network node. Its protocol makes the currency stock known in advance, and the maximum stock is only 21 million BTC
