U-disk coin miner

1. Now you can't find bitcoin, let alone make money, when you buy a computer to mine. If it was OK two years ago, when the price of coins was low and there were few miners, people regarded bitcoin as a kind of game. But with the rising price of coins, people began to use graphics cards to mine, commonly known as burning graphics cards. Later, people found that the speed of ASIC mining machine was faster. Therefore, GPU and CPU mining graally withdrew from the stage of history, and ASIC mining machine dominated the world. Now mining is a very professional thing, the cost of mining has been close to or even more than the money price. Mining by retail investors is basically unprofitable. Mining is becoming more and more centralized. I suggest you don't want to mine. If you are interested in bitcoin, you can buy some bitcoin or a low-power miner, commonly known as USB miner, which is about the size of a USB flash disk. Just experience mining.

IPFs is a file transfer protocol similar to http. If IPFs wants to run, it needs many computers (storage devices) in the network as nodes. In a broad sense, all participating computers can be called IPFs mining machines

in order to attract more users to join the IPFs network and contribute to the network, an encryption currency named filecoin is designed, which is distributed to the participants (nodes) as a reward according to the amount of contributed storage space and bandwidth. In a narrow sense, the computer specially designed for the purpose of obtaining the filecoin reward is called IPFs mining machine

because IPFs network needs storage space and network bandwidth, in order to obtain the highest profit ratio, IPFs mining machine usually strengthens the storage space and reces the power consumption of the whole machine. For example, more than 10 high-capacity hard disks are equipped, Gigabit or higher speed network cards are equipped, and ultra-low power architecture processors are used

of course, the mining machine provides storage services, so it can obtain revenue. The size of revenue is related to the configuration of mining machinery and the number of IPFs mining machinery

extended data

the reasons why it is not recommended to invest in IPFs are as follows:

1. IPFs technology is too early to be commercialized

IPFs now takes up a lot of bandwidth. IPNs is very slow at present, which is an obvious technical defect. It will be very difficult to realize dynamic web pages only through IPFs

There is no reasonable economic model, even if the token economy is added, it is difficult to realize the long-term natural ecological value

as a very cumbersome decentralized protocol, it is difficult for users to share files autonomously and spontaneously. In addition, even if users share files into the protocol, the files will be completely open and users cannot delete files effectively, so the security of valid files is threatened

the solution is to introce encryption and blockchain incentive mechanism. At the same time, it solves the security and storage power problems of files. However, as mentioned before, any node with workload proof under blockchain incentive mechanism will face an economic problem of continuous power on state

It is difficult to establish an ecological network with IPFs as the core under the influence of technical problems

The ecological application space of

IPFs is quite limited, and the project interaction speed realized by IPFs protocol is also very slow. Of course, it has a direct relationship with the number of nodes and the distance of calling

3. The miner is used to dig money, and the mine pool is used to deposit money

4. Yes
the advantage of the video card miner is that it can dig other coins after one coin is collapsed. AISC mining machine is more efficient, but it can only dig a single currency.

when building bitcoin, Nakamoto wants bitcoin to be a decentralized currency, not only for use and trading, but also for mining. But it backfired. With the increasing value of cryptocurrency such as bitcoin, mining has become an instry. The competition is more and more fierce, and the pursuit of mining computing power is higher and higher. Therefore, from ordinary computer mining, ASIC mining machine and GPU mining machine have evolved

the algorithm of ASIC mining machine is almost sha256, while the algorithm of GPU mining is different. For example, the algorithm of BTG is equihash, and the algorithm of BCD is optimized x13. Although it is not absolute, it can be simply considered that the currency of sha256 algorithm is generally mined by ASIC mining machine. Other algorithms are basically using GPU miner. There are also exceptions. Scrypt's Leyte coin used to be mined by GPU miner, but later scrypt's algorithm was also conquered by ASIC chips, such as ant miner L3 +, which is the ASIC miner used to dig Leyte coin

ASIC miner refers to the miner that uses ASIC chip as the core of computing power. ASIC is the abbreviation of application specific integrated circuit, which is a kind of electronic circuit (chip) specially designed for a specific purpose. Some mining machinery factories have designed ASIC chips specially for computing the sha256 algorithm of bitcoin, and the mining machinery using them is ASIC mining machinery. Because ASIC chip is only built for specific computing, its efficiency can be much higher than that of CPU. For example, the current mainstream ant miner S9 is ASIC miner, which uses 189 ASIC chips, the computing power reaches 13.5th/s, and the power consumption is only 1350W. As a comparison, the computing power of gtx1080ti, the flagship computer graphics card, will not exceed 60mh / s even if it is optimized well. The difference is tens of thousands of times

GPU miner refers to the miner that uses GPU graphics card as the core of computing power. Cryptocurrencies such as Ethereum, bitcoin and diamond use graphics algorithms, so the speed of computing with graphics card will be the highest. Compared with ASIC miner, GPU miner is more well-known, because it is a computer with enhanced graphics card configuration

the purpose of GPU miner is to make money, so we should pursue the power consumption ratio and maximum profit, so we should pay attention to the cost performance. Generally, the medium and high-end positioning graphics cards, such as AMD rx560 and rx570, have high power consumption ratio, which is a good choice for GPU miner. While flagship cards such as gtx1080ti and AMD vega64 have the strongest single card performance, they are not cost-effective in terms of price and power consumption

in addition, the ASIC miner also has some exotic procts, such as the USB miner of burning cat, which is slightly larger than the U disk, and the power consumption is only 2.25w, which is the smallest bitcoin miner at present

the above quoted digcoin.com - "Introction to mining machinery classification" has many professional terms. I hope it can help you, thank you

6. A mine pit is like a coal mining area, which can be g out by a miner
for example, a zero coin mine can be g 24 hours by a miner. According to the calculation power of the miner, an equal amount of coins can be g out

7. A9 is still considerable in terms of current revenue. Now it's about 620 yuan a day. Because the income of the first group of miners who used this mining machine to mine is still stable, and the initial income is also 550-650 up and down. The price may not fall, but will rise. Now the currency price is rising steadily, driving the price of mining machinery is also rising. There is also a serious shortage of cash on the market

8. Don't dig money directly. It's too much trouble. Get together and exchange GMCC with Ethereum

9. This kind of problem is very retarded. How can enterprises become the digital currency of the central bank? The central bank is an institution directly under the State Council. The central bank did not issue digital currency either. It just held a digital currency seminar and planned to issue digital currency. But this kind of digital currency will not become a reality until ten years at the earliest. Moreover, the design principles of this digital currency are different from those of Ruitai, Weimeng and bitcoin, and the control rights are different.
