3T miner

bitcoin mining is a process that uses computer hardware to calculate the location of bitcoin and obtain it

mining is an incentive process to record data in the bitcoin system. In the bitcoin system, indivial users have the right to pack blocks after calculating a specific hash value by using CPU or GPU to hash

and in order to reward this user for packing blocks, the system will give a certain amount of bitcoin as reward. Because this process is very similar to "mining" in real life, most people call this process mining. In addition to bitcoin, other electronic virtual currencies can also be obtained through mining rewards, such as Ethereum, Monroe and so on

extended data:

mining risk:

1, currency security

the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin

2, system risk

system risk is very common in bitcoin, and the most common one is bifurcation. Bifurcation will lead to a drop in currency price and a sharp drop in mining income. However, many cases show that the forking will benefit the miners, and the forked competitive currency also needs the miners' computing power to complete the minting and trading process. In order to win more miners, the competitive currency will provide more block rewards and handling charges to attract miners. Risk makes miners

2. Bitcoin is a kind of cryptocurrency based on decentralization, using peer-to-peer network and consensus initiative, open source, and blockchain as the underlying technology. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. Unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of money circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. 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

warm tips:
1. The above explanations are for reference only, without any suggestions
2. Before investing, it is recommended that you first understand the risks existing in the project, and clearly understand the investors, investment institutions, chain activity and other information of the project, rather than blindly investing or mistakenly entering the capital market. Investment is risky, so we should be cautious when entering the market

web link post bar example:

we will calculate the graphics card to dig bitcoin earnings

assuming you are HD 7950 awesome, according to Zhongguancun online information, approximately 500MHashs/s

HD 7950 is g to compare the power of the graphics card, calculate 500MHashs/s, converted to 0.5GH/s. I am your current graphics card, you don't need to buy it
the full load power consumption of HD 7950 is 210W, the graphics card mining is full load work, and the electricity charge is 0.6 yuan / kWh
I reckon that you have been digging for 180 days in a row, that is, half a year, 24-hour power on. You should pray that your computer will not hang up because of this
difficulty coefficient: the difficulty of bitcoin has been increasing. Generally, the calculation is increased by 30% in 11 days. I'm a little less. It is increased by 25% in 11 days

OK, all the parameters are ready, calculation
in calculation...

eh, how come it's a negative number

because you need to pay the electricity bill for your graphics card
and there is no bitcoin output every day, because your computing power is too low


suppose your graphics card is HD 7950 and the computing power is 0.5gh/s
at present, 200g ASIC mining machine is on the verge of elimination, because 3T mining machine is already looming in the market
but even the 200 g miner that is going to be eliminated is 4000 times of the 0.5 calculation power of your HD 7950

4. Avalon team has developed the world's first "variable computing power cluster system" (hashs for short, hyper array scalable hashing
System). In this system, the concept of single miner no longer exists, but the concept of mole cluster

taking Avalon 40 nm mole as an example, each mole has 295g computing power. According to the actual situation of the mine site, power supply and heat dissipation, users can freely choose to stack 1-40 moles (corresponding to about 0.3t-12t computing power) into a computing power cluster unit, which can be controlled by one terminal, one network cable and one IP address. Revolutionary technological innovation has raised the flexibility and simplicity of mine layout to an unprecedented level.

5. In fact, bitcoin mining can not blindly pursue the size of computing power, but also depends on the overall performance of the miner. For example, the single-mode group of Avalon mining machine 2 will be able to recover its cost in about 40 days, but the 800g recovery time of Avalon mining machine 3 is far away, unless the currency price rises. If you are a retail investor, it is suggested that you buy mining machines with small calculation power and fast cost recovery time, which should be regarded as playing. If you have abundant funds and the ability to set up large-scale mining plants, it is suggested that you buy mining machines with high calculation power and high profits. Avalon's 2.3t miner is said to be coming soon.

6. Bitcoin mining is simply to use the computing power of your mining equipment to solve mathematical problems and confirm network transactions, so as to ensure the safety of the whole bitcoin system. In return, bitcoin system will give miners unequal bitcoin rewards

the professional point is that mining is a distributed consensus system that includes the transaction data to be confirmed into the block chain, so as to complete the confirmation of these transactions. By mining, the data in the block chain can be stored in chronological order, the neutrality of bitcoin network can be maintained, and different computers on the bitcoin network are allowed to agree on the system state. To be confirmed, a transaction must be packaged into a block that complies with very strict cryptographic rules and verified through bitcoin network. These rules can prevent the modification of existing blocks, because once there is a change, all blocks will be invalid. Mining is as difficult as winning the lottery. No one can easily and continuously add new blocks to the block chain. Therefore, no one can control what content is included in the block chain or replace part of the content in the block chain to rece their cost

at present, bitcoin mining needs professional ASIC mining machines. For example, Avalon mining machine (commonly known as pumpkin Zhang mining machine), which has created countless number one mining machines in the instry, is said to be coming out soon, 28nm chips will be streamed soon, and 16nm chips are under development.

8. There is no unified price standard for how much to invest in a 1750 cone crusher in the market, usually hundreds of thousands or even millions. Due to the slightly different output, feed particle size, finished proct particle size and other parameters of different models, there is a price difference problem.

9. It depends on the requirements of sand making procts and the state of sand making raw materials, such as the daily output of finished sand, particle size, sand hardness and other indicators. There are also the state of raw materials for sand making, such as the mode of transportation, the overall size of block stone, etc. You need to first put forward specific requirements and ideas, and then let the equipment manufacturer make a detailed sand making process plan for you, and then carry out equipment selection and matching according to the process plan and output. You must ask the manufacturer to provide you with the weight of each equipment. You can estimate the price of the equipment according to the weight of the equipment. For such equipment, the unit price of 10000-13000 tons should be acceptable.
