Bitcoin mining policy risk

1.

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

As of July 24, 2020, the state has not issued any laws to prove that bitcoin mining machine is illegal

bitcoin mining machine is one of the ways to obtain bitcoin. Bitcoin is a kind of network virtual currency proced by open source P2P software

it doesn't rely on the issuance of specific monetary institutions, and it is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction

extended data

the issue and transaction of bitcoin are realized by mining, and it is cast at a certain but slowing rate. Each new block is accompanied by a certain number of new bitcoin from scratch, which is used as a coinbase transaction to reward the miners who find the block

the reward for each block is not fixed. For every 210000 blocks mined, it takes about four years, and the currency issuance rate is reced by 50%. In the first four years of bitcoin's operation, each block created 50 new bitcoins. Each block creates 12.5 new bitcoins. In addition to the block award, the miner will receive a handling fee for all transactions within the block<

It's not against the law

The laws and administrative regulations in China do not prohibit the proction, holding and legal circulation of bitcoin, nor do they prohibit the sale of bitcoin mining machines

2. The investment and transaction of "virtual currency" represented by bitcoin are on the rise. For this kind of virtual goods generated in the Internet environment after the development of Internet technology, there are policy and commercial risks in related transactions. However, under the premise of not violating the mandatory provisions of laws and administrative regulations, the contract signed by the parties is a valid contract

3. Bitcoin is generated by "miner" and "mining", and "miner" can be assumed by anyone in any place in the world. "Mining" is a process in which "miner" provides certain computer computing power according to the open source software provided by the designer, and obtains the special solution of the equation through complex mathematical operations, The miner who gets the special solution gets a certain amount of bitcoin reward

Because bitcoin is based on workload proof, it is related to computing power. To have computing power, we need to consume power, so its power consumption is very large. It is precisely because of such a large power consumption that the safe and stable operation of bitcoin system can be guaranteed

extended information:

according to the data of btc.com website, up to now, the computing power of the whole bitcoin network is about 51.65 eh / s, which is equivalent to 1.84 million bitcoin S15 (28T computing power, 1596w power) mining machines in operation, and the daily power consumption is about 69.92 million kwh. Divided by the current proction of 1800 bitcoins per day, excluding other costs, each bitcoin will consume 38800 kwh of electricity. "

from this point of view, although the current price of bitcoin is expensive, the cryptocurrency market website coinmarketcap.com shows that the current unit price is about $7900, but the cost of mining a bitcoin is not low at all

4. It's OK, but it's very difficult. It's a lot of brain work. It's better to play on chips. You can get income by shaking it, and then you can directly exchange it for withdrawal bitcoin. It's simpler

5. According to the rough statistics of chainchat, there are 20 million blockchain users in the world, and there are probably several million in China.

6. One of the differences: the score is different
Tencent credit score: the lowest is 300 points, the highest can be 850 points< Zhima credit score: the lowest score is 300, the highest is 950.
the second difference: different scoring standards
Tencent credit score: the score is obtained through comprehensive evaluation of the five indexes of "performance, security, wealth, consumption and social interaction"
sesame credit score: mainly through the five dimensions of "performance ability, identity characteristics, behavior preference, interpersonal relationship and credit history"
the third difference: enjoy different rights and interests
at present, as Tencent credit score is still in the testing stage, the services it can enjoy are particularly limited, but comparatively speaking, sesame credit score has been developed for a period of time, with more complete functions
Tencent credit score, the most anticipated is "micro particle loan", but for now, there is no correlation between Tencent credit score public test qualification and micro particle loan. Of course, it does not rule out the positive significance of Tencent credit score query to the opening of micro particle loan entrance.

In fact, blockchain has been developing at a high speed since its emergence. Bitcoin, as a derivative of blockchain, is also the ancestor of all virtual currencies, and its value is very high

now there are only two ways to get bitcoin, one is to buy it, the other is to use ha Yu miner Mining! I believe the value of bitcoin will be the highest in the future

high acquisition cost

at present, if investors want to obtain bitcoin through the "mining" channel, the cost is already very high. As the amount of bitcoin on hand is proportional to the complexity of the algorithm, the number of people involved in mining is also proportional to the complexity of the algorithm. It is impossible to use ordinary home computers to "mine". At present, the market price of high configuration professional "mining machine" has reached 300000 yuan. Through the online trading platform, the current market is as high as 1 bitcoin to 122.49 US dollars

to consider whether the political environment has enough support

as a decentralized virtual currency, whether bitcoin can be recognized by governments is very critical. Due to the lack of supervision, bitcoin is easy to become a channel for money laundering, bribery and asset transfer. More importantly, bitcoin lacks strong credit support in essence. As a currency, it lacks both the commodity function behind the gold standard and the mandatory guarantee of credit currency. When the market value of bitcoin continues to rise and has a certain impact on the real currency, governments may declare it illegal. In mid May, the US Department of Homeland Security froze two bank accounts owned by Mt. GOx, the world's largest bitcoin exchange. This is a systemic risk that must be considered

Technical Security

the design algorithm of bitcoin is relatively safe at present, but each online trading platform is not without loopholes. With the rising market value, bitcoin has become the target of network hackers. Users' bitcoin is stolen and bitcoin trading center is attacked by hackers frequently, which will bring unknown fluctuations to the trend of bitcoin

what is the appreciation space of bitcoin?

money supply should keep pace with economic development. From the design principle of bitcoin, the supply speed of bitcoin is determined by algorithm, and has nothing to do with market demand and economic development. Although bitcoin eliminates inflation in theory, its relative lack of total amount and no secondary currency is the biggest weakness. Bitcoin is more likely to bring deflation than gold standard. Deflation is just as harmful as inflation, which directly deviates from the liquidity nature of money and is destined to have a very limited audience

the best time to enter the market may have passed

from the perspective of market trend, bitcoin began to rocket up this year from the initial exchange rate of 1 US dollar to 1309.03 bitcoin, reaching the highest record of 266 US dollars to 1 bitcoin in April this year. This is because, according to the algorithm, the supply of bitcoin is halved every four years, which is exactly the beginning of the new four years from this year. The time point at which supply is halved is certainly a sensitive time window

investors should have a strong enough heart

bitcoin trading has a high risk, it does not have the same limit as the stock market, and trading is open 24 hours a day. Due to the small number of chips, the price of bitcoin is easily controlled by the makers. It is possible that the price of bitcoin will rise several times a day. At the same time, it is possible to wake up and find that most of the assets are lost

9. Your friend should be investing in bitcoin mining. The risk of investing in bitcoin mining is relatively high. There are two main risks in investing in bitcoin mining. One is that the computing power of bitcoin network is growing too fast. Now it's more than 700 yuan a day. In two months, it's only a few dozen yuan a day. So you can calculate five months. There are some problems at this time. Second, the price changes very fast, In five months, it will not be the current price. It may go up or down sharply
I suggest that we should understand the market and not invest blindly.

for one thing, the bubble risk of bitcoin is not enough to constitute systemic risk. This is because the participants are mainly indivials, while normative financial institutions are hardly involved. The two bitcoin does not have the collateral nature of formal finance, that is to say, even if the price of bitcoin falls sharply, there will not be a risk transmission to the financial market. p>

high risk and high return, many things are fried
