1. In order to understand the technical principle of bitcoin, we need to understand two important cryptographic techniques: hash code: it converts a long string into a fixed length string, and its conversion is irreversible, that is, it is impossible to guess the original string from hash code. Sha256 is mainly used in bitcoin protocol
public key system: corresponds to a public key and a private key, keeps the private key in the application and publishes the public key. When Party A transmits information to Party B, it can use Party A's private key to encrypt the information, and Party B can use Party A's public key to decrypt the information, so as to ensure that the third party cannot impersonate Party A to send the information; At the same time, when Party A transmits information to Party B, it is encrypted with Party B's public key and sent to Party B, and then Party B decrypts it with his own private key, so as to ensure that the third party cannot eavesdrop on the communication between the two people. RSA is the most common public key system, but the lliptic curve digital signature algorithm is used in bitcoin protocol. What's the difference between cash and bank account? Bitcoin is an electronic currency in BTC. In this article, it is also used to refer to the whole bitcoin system. Like opening an account in a bank, the corresponding concept in bitcoin is address. Everyone can have one or more bitcoin addresses, which are used to pay and collect money. Each address is a string that starts with 1. For example, 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 keep all transaction records and maintain the book balance of each account, while bitcoin's transaction records are jointly maintained by the whole P2P network through a pre agreed protocol. How much money is in my account address? Although the current account balance can be seen by bitcoin software, unlike banks, there is no place to maintain the book balance of each address. It can only calculate the account balance in real time through all historical transactions. 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 to address B, and the payment amount is e. In order to prevent the 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 receiving the transaction information can use the public key of address a to verify that the transaction information is indeed sent by address a. Of course, trading software will help us do these things, we just need to input 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 bitcoin system, which needs to be elaborated. For the sake of simplicity, only bitcoin protocol has been implemented. In the current version, each network node will save all transaction information synchronously. There are two kinds of transaction information in history, one is & quot; Verified & quot; The transaction information, that is, the verified transaction information, is stored in a series of "blocks". Each & quot; block" Is the previous & quot; bock" The ID of each block is the hash code of the hash code of the block and the new transaction information (see an actual block). The other category refers to those who also & quot; Unverified & quot; The transaction information just paid above belongs to this category. When a network node receives new unverified transaction information (possibly more than one), it can calculate the book balance of each address at that time because the node keeps all the transaction information in history, so it can calculate whether the transaction information is valid, that is, whether there is enough balance in the payment account. After eliminating the invalid transaction information, it first takes out the last & quot; block" Then, the unverified transaction information is combined with the ID, and a verification code is added to form a new "block". It needs a lot of calculation to build a new block, because it needs to calculate the verification code, so that the above combination becomes a block, that is, the first several bits of the hash code of the block are 1. At present, the first 13 bits need to be 1 (generally, the specific method is uncertain), which means that if the block is generated by enumeration method, the average number of enumerations is 16 ^ 13. Using CPU resources to generate a block is called "gold mining", because the proction 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 will broadcast to other network nodes. However, this network block may not be accepted by the network, because it is possible that other network nodes have proced the block earlier. Only the earliest block or the block with the largest number of subsequent blocks is valid, and the remaining blocks are no longer used as the initial blocks of the next 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 begins to calculate whether the transaction is valid (that is, whether the account balance is enough to pay), and attempts to generate blocks containing the transaction information. When six blocks (one direct block and five subsequent blocks) contain the transaction information, the transaction information is considered "verified", so that the transaction is formally confirmed, and the other party can confirm the successful payment. A possible problem is that I will pay the balance of address a to address B, and at the same time pay to address C. If I only verify that the single comparison transaction is valid. At this point, my way of cheating is to generate six blocks including B to B and six blocks including C to C before the truth is revealed. Because I need a very long CPU time to generate a block, compared with the whole network, the probability of my cheating success is very small. What is the motivation of network nodes to proce blocks? As can be seen from the above description, in order to make the transaction information effective, 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 let other network nodes help to proce blocks as soon as possible? The answer is very simple. The agreement stipulates that BTC will be rewarded for the address where the block is proced, as well as the Commission promised by both parties. At present, the reward for procing a block is 50btc, which will be halved every four years in the future. For example, the reward will be 25btc from 2013 to 2016. Is the transaction anonymous? Yes, and No. All bitcoin transactions are visible. We can check all transaction records of each account, such as mine. But what's different from the banking monetary system is that everyone's account itself is anonymous, and everyone can open many accounts. In general, anonymity is not as good as it claims. But bitcoin has another advantage in doing black market trading: it can't be frozen. Even if the police trace a bitcoin address, there is nothing they can do unless they trace the computer used by the exchange based on the Internet address. How to ensure that bitcoin does not depreciate? Generally speaking, in the case of equivalent trading activities, the value of money is inversely proportional to the amount of money issued. Unlike the traditional money market, the central bank can determine the amount of money issued. Bitcoin does not have a central issuing institution. Only by procing blocks can we get a certain amount of BTC currency. Therefore, bitcoin's new amount of money depends on: 1. The speed of procing blocks: bitcoin's agreement stipulates that the difficulty of procing blocks is fixed at an average of 2016 every two weeks, about 10 minutes. Moore's law of doubling CPU speed every 18 months will not speed up the proction of block. 2. The number of rewards for block proction: at present, 50 BTC is awarded for each block proced, which is halved every four years. In 2013, 25 BTC is awarded, and in 2017, 12.5 BTC is awarded. Considering the above two factors, bitcoin's currency issuing speed is not controlled by any single node in the network. Its protocol makes the currency stock known in advance, and the maximum stock is only 21 million BTC
public key system: corresponds to a public key and a private key, keeps the private key in the application and publishes the public key. When Party A transmits information to Party B, it can use Party A's private key to encrypt the information, and Party B can use Party A's public key to decrypt the information, so as to ensure that the third party cannot impersonate Party A to send the information; At the same time, when Party A transmits information to Party B, it is encrypted with Party B's public key and sent to Party B, and then Party B decrypts it with his own private key, so as to ensure that the third party cannot eavesdrop on the communication between the two people.

2. Users can buy bitcoin, and at the same time, they can use computers to do a lot of calculations according to the algorithm to "mine" bitcoin. When users "mine" bitcoin, they need to use the computer to search for 64 bit numbers, and then compete with other gold miners by repeatedly solving puzzles to provide the required numbers for the bitcoin network. If the user's computer successfully creates a set of numbers, then they will get 25 bitcoins. Due to the decentralized programming of the bitcoin system, only 25 bitcoins can be obtained every 10 minutes. By 2140, the maximum number of bitcoins in circulation will reach 21 million. In other words, bitcoin system is able to achieve self-sufficiency, resist inflation through coding, and prevent others from destroying these codes

3. There are four common trading forms of bitcoin: spot, futures, options, ETF
1, spot trading
spot trading and stock trading are almost the same, buy low and sell high, earn the middle price difference! However, bitcoin is a T + 0 mode, trading anytime and anywhere, and there are no opening, closing, suspension and many other restrictions. It is open to trading 365 days a year
2. Futures trading is often referred to as contract trading. I believe most people can't resist the temptation of contracts. Contracts can be long and short, and can also be leveraged. The maximum support is 100 times, which indirectly magnifies the benefits and risks by 100 times, because human nature is inherently greedy. However, the difficulty coefficient of making money in the contract is high. Because bitcoin fluctuates greatly, it is possible to burst the position in an instant. Therefore, futures trading should be cautious
3. Option trading
the nature of option trading is the same as that of spot trading, i.e. expected call to buy up, expected put to buy down
since the nature of options and spot is the same, what is the difference between them? Simple comparison:
for example, bitoffer, the first bitcoin option in the world, has no margin, no handling charge and no exercise
(the only option in the world that doesn't need to exercise)
1. For spot, it costs US $7500 to buy a bitcoin
2. For option, it costs US $5 to buy a bitcoin option
when bitcoin rises from 7500 to US $8000, the spot earns us $500 and the option earns us $500
the benefits of the two are the same, but the cost difference is 1500 times
this is the case with options, which is the same as the spot calculation of profit space, except that you don't need to pay the full amount, just need to pay a little deposit Different from the traditional European options)
4. ETF fund trading
ETF is usually called trading open-end index fund, which is a very popular financial derivative in the traditional financial market. Bitoffer's launch of bitcoin ETF fund increases the fixed leverage on the original basis, because there are a certain number of futures contract positions behind the proct
What's the difference between bitcoin ETF and spot< In this year's bitcoin proction rection, in theory, X2
2. Mining machinery needs to be upgraded, in theory, X2
3. The current price of bitcoin is 7500x4 = US $30000 (expected price after next year's proction rection)
ring this period, the return comparison between holding spot money and ETF fund is as follows:
1, Up to 15 times (compound interest calculation)
there is no doubt that bitcoin ETF is the best investment choice!
1, spot trading
spot trading and stock trading are almost the same, buy low and sell high, earn the middle price difference! However, bitcoin is a T + 0 mode, trading anytime and anywhere, and there are no opening, closing, suspension and many other restrictions. It is open to trading 365 days a year

ring this period, the return comparison between holding spot money and ETF fund is as follows:
1, Up to 15 times (compound interest calculation)
there is no doubt that bitcoin ETF is the best investment choice!
4. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system. According to the notice on preventing the financing risk of token issuance, there is no approved digital currency trading platform in China. According to China's digital currency regulatory framework, investors have the freedom to participate in digital currency transactions at their own risk

5.
According to the regulations of notice 2014-21 of the IRS:
1. The information range of virtual currency payment is consistent with that of other property payment
2. Virtual currency paid to service providers and independent contractors should be taxed, and the tax rules of freelance also apply to virtual currency. Taxpayers usually have to get form 1099-MISC
3. When using virtual currency to pay wages to employees, they must also pay taxes, and they also need to pay federal income tax and payroll tax
4. The third party accepting virtual currency settlement payment on behalf of the merchant must report the payment status in form1099-k, payment card and the third party network dealer
5. Based on the fact that the virtual currency in the hands of taxpayers is a kind of capital asset, the gains or losses in the transaction of virtual currency and the sales of virtual currency need to be taxed
extended information:
legal status of bitcoin in China
in China, the regulations on the administration of RMB prohibit the proction and sale of token tickets. Because there is no clear judicial interpretation of the definition of token ticket, if bitcoin is included in the "token ticket", the legal prospect of bitcoin in China will face uncertainty
the notice of the Ministry of culture and the Ministry of Commerce on strengthening the management of virtual currency of online games (Wen Shi Fa [2009] No. 20) on June 4, 2009 stated that the application scope of virtual currency of online games was defined for the first time, and the distinction between the current virtual currency of online games and the virtual props in the game was made; At the same time, the notice said that the "notice" stipulates that enterprises engaged in related services must be approved before they can operate< br />
6. This kind of income is too enviable. In this way, don't pay too much attention to the tax rate. Let's make some contribution to the cause of the country,
7. The IEX coin issued by the iexotc exchange is good. There will be a fixed dividend income if you buy it
8. No, you don't need to earn it. Otherwise, those who earn tens of millions or hundreds of millions will have to pay taxes.
9. The answer is quite a few, but not many to the point
the motherboard supports PCIe × 16, the problem is not big, in theory, the mainstream of the lower end graphics card can be used. But considering your weak small power supply, 96gso can be directly ignored. The rating should be more than 230W. The TDP of your original whole system is about 200W. Is the rating 230W? Brand machine in this respect usually (I mean usually ~ ~) will not shrink, the rating should be above 250W. The old 65nm and 55nm cards will not be considered. We recommend the enhanced version x2
of YinChi GT220 http://detail.zol.com.cn/vga/index216225.shtml
tdp60w is not available, so it is affordable and the price is reasonable
the performance is better than 95gt and 4650, slightly inferior to 96gso G94 and HD4670. It's enough for your U. And this kind of low-end small card, the size will not be very big, card body is quite short, HTPC small chassis is no problem, you can absolutely plug in.
