Mining risk of 2019 bitcoin
the investment of bitcoin should be in two aspects in its present form, a bitcoin is worth tens of thousands of yuan. But because there are fewer and fewer bitcoin data codes, you need more time and more cost to get bitcoin. You know, the lowest price of a bitcoin miner is 3000 yuan. And because bitcoin has to do a lot of calculations to get a bitcoin miner to operate for a long time. In addition to the cost of these mining machines, site costs and electricity charges. It's hard to make money
unless you don't invest in mining machines, you invest in some illegal software. Let these illegal software invade other people's computers and mobile phones. Other people's computers and mobile phones do a lot of bitcoin computing and mining. In this way, the cost of mining machine, electricity, flow, heat dissipation and so on are saved. But we need to know that this is a violation of national laws. This will also allow other people's mobile phones to carry out a lot of calculations after power on, encroach on other people's memory, and make other people's mobile phones scrapped earlier
this depends on the CPU computing time of your computer, and on your network speed. If you use an ordinary home computer or a personal mobile phone. You don't have to get a bitcoin a year
unless there are more powerful mining machines. Of course, it will cost more. Unless you don't invest in mining machines, you invest in illegal software. Let these illegal software invade other people's computers and mobile phones. Other people's computers and mobile phones do a lot of bitcoin computing and mining. In this way, the cost of mining machine, electricity, flow, heat dissipation and so on are saved. But we need to know that this is a violation of national laws. This will also allow other people's mobile phones to carry out a lot of calculations after power on, encroach on other people's memory, and make other people's mobile phones scrapped earlier< br />
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
extended information:
{rrrrrrr}
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
Let me tell you the answer first: No
or don't invest all of bitcoin. Let me give you a brief analysis
first of all, let's talk about 100000 yuan. If the 100000 yuan is a windfall, we suggest that you allin invest in bitcoin, which may be several times more when you take it out at the end of this year. There will be another windfall
if the 100000 yuan is a year-end bonus, you can consider investing half of it in blockchain and bitcoin
if the 100000 yuan deposit is your hard-earned money, you must be cautious in your investment, so first of all, you are not recommended to invest in blockchain
in fact, your question tells me two basic facts: 1. You are Xiao of blockchain / currency circle; 2. You have a little deposit and want to manage money, or you need to make some money
so from my point of view, I don't recommend you to buy bitcoin or make any other blockchain investment, because there is a saying that a person can't make money beyond his cognition, and the blockchain world is beyond your cognition for you, and the coin circle is basically an extension or part of the financial system. And the financial system is the most cruel and ruthless world. When you want to make money, you should also think that there are hundreds of thousands of people, millions of people who have the same ideas as you, so as to drive them into this bloody and merciless market. So you ask yourself, can you make sure you make money
first pour a basin of cold water on you, and then answer your questions seriously. Let's take a look at the historical trend of bitcoin
I feel optimistic that the recovery may come slowly, the Federal Reserve's move may be the beginning of financial release, and the capital market may recover slowly. As a small part of the financial market, the blockchain world may also recover
from the perspective of investment, bitcoin in the blockchain world is not only the genesis currency, but also the mainstream currency that accounts for the vast majority of the total market value at present. Therefore, if you really want to invest in the blockchain world, bitcoin is the best choice
however, please note that from the perspective of professional investment advice, risks should always be shared. Exclusive bitcoin will be taken off by a currency, and it will also fall miserably. So please consider holding other mainstream currencies, such as BoChang coin, which is known as "the last good heart of the blockchain", which is also the most powerful counter trend growth currency in the bear market of the currency circle. For a long time, when the mother of other currencies, including bitcoin, didn't know each other, BoChang was the only currency that was growing slightly, which was a miracle
another example is Ethereum. Although Ethereum's hard fork has been delayed for a long time, the arrival of Constantinople's hard fork upgrade will make Ethereum the most eye-catching star in a short time. At this time, the investment can be regarded as low-level market entry, and you can make a profit by waiting for high-level investment
finally, back to my answer, if you don't even know wave field, bitcoin, Constantinople hard fork and other words, how can you determine whether you can make a sum of money in the world of currency. So this in itself is a very high risk thing
a strange capital market will swallow up all your savings. Although some people get rich overnight, they are a few people after all. If you are sure to invest in the blockchain world, bitcoin can be invested. However, from the perspective of risk sharing, please buy some other mainstream currencies to minimize the risk. Finally, I wish you a happy investment and a big fortune in the year of the pig. Please be cautious in your investment
is to read more about the various currencies or project's white paper. I pay attention to my WeChat official account: "Nanjing block chain" can get thousands of white papers free of charge, so that you will have a better understanding of the chain world. p>
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<
source: Internet - bitcoin mining machine
in the very early days, when the computing power of bitcoin was very low, the computer could also carry out a lot of calculations according to the algorithm to "mine" bitcoin
when users "mine" bitcoin, they need to search for 64 bit numbers by computer, 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 group of numbers, they will get the bitcoin awarded by the block. However, e to the rising value of bitcoin, the number of users of bitcoin mining is very large. There are millions of professional mining machines mining at the same time, and the output of bitcoin is very limited every 10 minutes. As a result, tens of millions of people scramble for a block. Therefore, if you use personal computers to mine alone, you may not be able to grab a block in a whole year, People came up with a method of group mining, so the mining pool was born. There are a lot of users who play after mining
I hope you will adopt it.
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.
