Buy a miner with 70 yuan

1. Professional mining still has a certain threshold, which needs professional operation and maintenance. If someone tells you that as long as you pay for the miner, the cow can wait to collect money, then this is basically a fraud project.

2. The revenue from the purchasing power contract varies from two to three years. You need to book and purchase the mining machinery in advance, search for electricity or look for the mine trusteeship, which has a lot of deployment costs and electricity costs. It also needs manual maintenance. The mining machinery has a service life. In addition, the mining machinery market is updated rapidly, so the cost of such calculation is very high, and it is also very troublesome.

3. Depending on personal preferences and advantages, those who are willing to take this as their lifelong career can get a mining plant, parcel a piece of land, and hire a few more people to watch the mining machine for you. If ordinary people enter, I suggest that they choose the platform to dig. They are too tired to dig, and the people who come here

4. Now a lot of people are speculating money and buying mining machines to dig crazily, so the price is not cheap. Basically, it's about 20000-40000. Recommend a digging chain network, which introces the configuration of mining machine and all kinds of information, you can understand it. Just ask for an ace ē

5. Hello! First of all, what kind of process do you adapt to? Therefore, it is necessary to make spectrum of the ore first, then make quantitative analysis of the corresponding valuable elements according to the spectrum analysis results, and then do beneficiation test. According to the mineral processing test, calculate the output value, mining, beneficiation and smelting cost, and calculate the profit margin of instrial proction. At this time, the equipment can be determined according to the technological process selected by the beneficiation test. The equipment must not be determined according to the experience, the suggestions of a single technician or the suggestions of the equipment factory without test basis. Too many factories built like this stop there, causing heavy losses!

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

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

7. There will be no pie in the sky. Don't easily believe the online propaganda, which is similar to bitcoin. If there is such a light thing that you can earn 8000 yuan without going to work every day, then you don't need to do anything and just open mines there every day. If you have spare funds in your hand and want to invest and manage money, you can try the online loan platform. If those who can't understand it directly invest their money in yu'ebao or caiyuantong, these platforms are very safe, and the income is higher than the bank interest rate
let's see what others say.

Xiaowei is an ordinary housewife in a small town under the jurisdiction of a central province. However, she has been in touch with "dkcoin" and "mining" since January 2017, claiming to be a "digital currency player"“ Blockchain, decentralization, everyone can buy it, you know? "“ During the Spring Festival, when she enthusiastically introced her experience of playing digital currency, we soon found a "flaw": she did not know what distributed accounting, computing power, hash value, OTC trading, or even mining machines were

It was also in the beginning of 2017 that he joined and successively mobilized people around him to join the "rush to buy and rent" army. Behind her, there are her relatives and neighbors in her neighborhood, each of whom has invested tens of thousands of yuan
