Bitcoin after sale
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.
Mine card refers to the graphics card used by bitcoin mining machine, mostly amd graphics card
mine disaster refers to the decline in the price of bitcoin and the sale of second-hand mine cards
bitcoin mining machine graphics card long-term high load operation, graphics card service life will be reced accordingly, so the price will be cheaper
extended data:
bitcoin mining machine is a computer used to earn bitcoin. This kind of computer generally has professional mining chips, and mostly works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server
bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high
According to the provisions of the Supreme People's Procuratorate and the Ministry of public security on the standards for prosecution of economic crime cases, those who illegally raise funds by means of fraud for the purpose of illegal possession shall be prosecuted under one of the following circumstances: 1. Indivial fund-raising fraud, the amount of which is more than 100000 yuan; 2; 2. Unit fund-raising fraud, the amount of more than 500000 yuan
report the illegal fund-raising companies to the economic investigation departments of public security organs. There are three ways to report the case:
1. Report the case directly to the public security organ
2. Report to the main regulatory authorities of various instries, for example, those involved in the banking instry can be reported to the CBRC, those involved in the securities instry can be reported to the CSRC, those involved in insurance can be reported to the CIRC, and those involved in financing guarantee companies and non financing guarantee companies can be reported to the provincial financial office or the provincial instrial and commercial bureau
3. Report to the "publicity platform for prevention and control of economic crimes"
extended information:
illegal fund-raising (according to the provisions of the notice on banning illegal financial institutions and illegal financial business activities) refers to the fact that units or indivials raise funds from the public by issuing stocks, bonds, lotteries, investment fund securities or other creditor's rights certificates without the approval of relevant departments in accordance with legal proceres, And promise to repay the principal and interest or give return to the investor in currency, material object and other ways within a certain period of time
according to the relevant provisions of the notice on further cracking down on illegal fund-raising activities (YF [1999] No. 289), "illegal fund-raising" can be summarized as follows:
(1) absorbing funds by issuing securities, membership cards or debt certificates
the more common ones are: issuing stocks, bonds, lottery tickets, investment funds and other rights certificates in disguise or in the name of futures trading and pawn. Illegal fund-raising by claiming shares, participating in dividends, entrusted investment and entrusted financial management. Through membership card, membership card, seat card, preferential card, consumption card and other ways of illegal fund-raising
(2) divide property, real estate and other assets equally, and raise funds with high interest by selling the disposal right of their shares
the latest change is: illegal fund-raising by selling its shares and committing to after-sale and leaseback, after-sale and buyback, regular rebate, etc recent changes: using underground banks to raise funds
the common ways are: illegal fund-raising by means of commodity sales and leaseback, buy back and transfer, development of members, merchant joining and "fast integration method" (6) illegal fund-raising in the form of pyramid selling or secret series (7) illegal fund-raising in the form of orchard or manor development for example, illegal fund-raising in the name of planting, breeding, project development, manor development, ecological and environmental protection investment (8) illegal fund-raising by means of "virtual" procts constructed by modern electronic network technology, such as "e-shop", "e-department store" investment entrustment, maturity repurchase, etc (9) illegal fund-raising in the form of Internet investment fund
Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system
unlike all currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation
the decentralized feature and algorithm of P2P can ensure that it is impossible to artificially control the value of bitcoin by mass manufacturing. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity
extended data:
bitcoin is the first distributed virtual currency. The whole network is composed of users and there is no central bank. Decentralization is the guarantee of bitcoin's security and freedom. Bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
bitcoin requires a private key to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself. Bitcoin can be remitted free of charge, but in the end, a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster execution of the transaction
As a means of payment from a to B, bitcoin has no cumbersome quota and proceres. If you know the other party's bitcoin address, you can pay. Users can explore the computing power of different hardware on many platformsfor example, if there is a certain harvest of garlic and more people buy it, the supply can't meet the demand and the price is high, while less people buy it. If the garlic can't be bought, the price will be lower.
