How to buy a miner in mainland China
at present, there are two most famous bitcoin miners in the world: ant miner of bitcoin mainland and Avalon miner of Zhang Nangeng. The latter is also the inventor of the first ASIC chip miner in the world
when choosing mining machines, we should first look at computing power, second look at power consumption, and third look at historical reputation
computing power is the ability of a machine to perform operations, that is, how many hash operations can this machine perform per second. At present, the computing power of mainstream bitcoin mining machines is 14T, that is, 14 * 10 ^ 13C hash collisions per second
power consumption is an indicator of power consumption when the mining machine is running, which is directly related to the cost of mining. Under normal circumstances, the mining machine will operate 24 hours a day, so even if the power consumption of different types of mining machine is very small, the power cost gap is very large
the historical reputation represents the stability of the miner's operation. You can know the overall user evaluation, after-sales service and whether the prepayment miner can deliver on time from different purchase channels
to say that the simplest way is to directly select the latest spot miner model. Because the latest mining machine power consumption will be relatively small, computing power is relatively high, input-output ratio is the most cost-effective
we need to remind you that the noise of the miner is relatively loud, which is also a tough injury of the miner.
No illegal
in the bitcoin risk notice jointly issued by the people's Bank of China and other five ministries and commissions at the end of 2013, bitcoin is clearly defined as a special Internet commodity, and people can buy and sell it freely at their own risk. But it denies the monetary nature of bitcoin< The Article 143 of the general provisions of the civil law stipulates that "the civil legal act with the following conditions is valid:
(1) the actor has the corresponding capacity for civil conct< (2) the expression of intention is true< (3) it does not violate the mandatory provisions of laws and administrative regulations, public order and good customs. " The announcement of the seven ministries and commissions is neither a law nor an administrative regulation, and can not be used as a legal basis for judging whether a civil juristic act is valid or not; The law does not go back to the past. Therefore, the bitcoin transaction has legal effect, and the bitcoin obtained from the transaction is protected by law. Therefore, legal disputes arising from trading activities, including civil or criminal cases, should be subject to jurisdiction. Courts or public security organs can not refuse to accept bitcoin because they think bitcoin is not protected by law

transaction mode
bitcoin is e-cash similar to e-mail, and both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address. The following table lists some websites that download bitcoin wallets and addresses for free
a bitcoin address is a string of about 33 characters long, consisting of letters and numbers, always starting with 1 or 3, such as & quot& quot; Bitcoin software can generate address automatically, and it does not need to exchange information online when generating address, so it can be offline [2]. More than 2 bitcoin addresses are available. Figuratively speaking, there are about two grains of sand in the world. If there is an earth in each grain of sand, then the total number of bitcoin addresses far exceeds the number of all the sand on all these "earths"
the bitcoin address and private key appear in pairs, and their relationship is just like the bank card number and password. A bitcoin address is like a bank card number, which records how much bitcoin you have on it. You can generate bitcoin address at will to store bitcoin. When each bitcoin address is generated, a corresponding private key of the address will be generated. This private key proves that you have ownership of the bitcoin at that address. We can simply understand the bitcoin address as the bank card number, and the private key of the address as the password of the corresponding bank card number. Only when you know the bank password can you use the money on the bank card number. Therefore, please keep your address and private key when using bitcoin wallet
after the transaction data of bitcoin is packaged into a "data block" or "block", the transaction is initially confirmed. When a block is linked to a previous block, the transaction is further confirmed. After six block confirmations in a row, the transaction was irreversibly confirmed. Bitcoin P2P stores all transaction history in a "blockchain.". The blockchain continues to extend, and once new blocks are added to the blockchain, they will not be removed. Blockchain is actually a distributed database composed of a group of scattered client nodes and all participants, which is a record of all bitcoin transaction history. Nakamoto predicts that when the amount of data increases, users hope that not all the data will be stored in their own nodes. In order to achieve this goal, he uses the hash function mechanism. In this way, the client will be able to automatically eliminate those parts that it will never use, such as some very early bitcoin transactions
although bitcontinent is not a good bird, it is suggested that the risk tolerance should not touch mining
ordinary retail investors should remember to stay away from the mining link of ASIC miner. The water in it is too deep. How can you play with it
this is the way to buy a futures miner. When you buy a futures miner, you should not only look at the profits at that time, but also predict the fluctuation of the middle currency price and the sharp rise of the calculation power

There is a flat head screw at the bottom of carburetor, which can be unscrewed
carburetor is a key part of engine, small changes may affect vehicle performance. Therefore, in the process of carburetor disassembly, appropriate tools should be used, and the force should be moderate, so as to prevent the deformation of parts. The disassembled parts should be placed in order in order to prevent missing or wrong assembly
in the process of cleaning the carburetor, if more deposits are found in the float chamber of the carburetor, it is often caused by the failure of the gasoline filter. At this time, the gasoline filter should be checked. If the failure is confirmed, the gasoline filter should be cleaned or replaced
extended information:
precautions:
1. Carburetor is a key part of engine, small changes may affect the vehicle performance. Therefore, in the process of carburetor disassembly, appropriate tools should be used, and the force should be moderate, so as to prevent parts from deformation. The disassembled parts should be placed in order in order to prevent missing or wrong assembly
2. The carburetor should be cleaned in a clean place, the outer surface of the carburetor should be cleaned, and the internal parts can be cleaned with special cleaning agent for carburetor or instrial gasoline. In addition to impurities, pay attention to clean the gasoline gum on the surface of parts
3. Clean the cleaned parts with compressed air, and do not wipe them with cloth or paper that may cause burr to prevent re pollution. It is forbidden to poke the blocked small hole with steel wire and other hard objects to prevent the change of carburetor performance caused by changing the aperture. Gasoline or compressed air should be used to wash out
2. If you want to motivate others, motivate yourself first; Require employees to strive for excellence, leaders must first have the determination and confidence to strive for excellence. In this way, leaders can infect and inspire everyone with an invisible personality charm
3. Fair. Justice is fair and reasonable. It requires leaders to treat their employees equally, and not to be intimate with them. Whether leaders are fair or not has a fundamental impact on the enthusiasm of employees
4. Trust. Lack of trust in an organization can be fatal in the end. The trust in any kind of incentive measures depends on leaders' trust in their subordinates and subordinates' trust in leaders. Trust is both sides, the trust of the unit will not last long. In an environment of mutual trust, every employee will become an important worker
5. The dialectical principle of material incentive and spiritual incentive. From the incentive theory of management science, we can see that material incentive is the foundation and spiritual incentive is the key. In the current economic situation of our country, the demand for health care has been basically solved, and the incentive measures are more and more important. At the same time, we should not ignore the fair theory about incentive measures. Leaders should pay attention to the fairness of material interests and spiritual treatment, otherwise it will affect the enthusiasm of employees
6. The principle of comprehensive application. There is no superior or inferior between any two kinds of incentive measures, only whether to adjust measures to local conditions. The actual process of incentive cannot be fully realized by one method. In a certain period of time, there is often the maximization of the effect of some incentive measures, but it does not exclude or do not need other incentive measures. Therefore, to effectively mobilize the enthusiasm of employees, we must comprehensively use various incentive measures to overcome the singleness.
