How to calculate mining

1.

You can refer to the following, according to some commonly used graphics cards in the Internet bar market, sort out the price and calculation power of a related graphics card, as well as the expected return to the current period, It can be used as a reference:

{rrrrrrr}

power consumption: 243w
computing power: 22.4m
price of graphics card: 1999 yuan
quantity of eth g every 24 hours: 0.015
revenue generated every 24 hours: 24.48 yuan

Video card (graphics card) full name display interface card, also known as display adapter, is the most basic configuration of computer, one of the most important accessories. As an important part of the computer host, the graphics card is the equipment of digital to analog signal conversion, and it undertakes the task of output display graphics

the graphics card is connected to the main board of the computer, which converts the digital signal of the computer into an analog signal for the display. At the same time, the graphics card still has the ability of image processing, which can help the CPU work and improve the overall running speed. For those engaged in professional graphic design, graphics card is very important. Civil and military graphics chip suppliers mainly include amd (ultra micro semiconctor) and NVIDIA (NVIDIA). Today's TOP500 computer, including graphics card computing core. In scientific computing, graphics card is called display accelerator

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

3. It's a very simple method. You can directly input your electricity bill with the small tools of the mine pool, such as the coin printing mine pool, and you can see the corresponding daily output of each model and the income converted into RMB. At the same time, you can see the market prices of different models of machines on today's miner's official website, and you can calculate the return cycle.

4. Press F3 in the game, the upper left corner has x, y, Z coordinates, y is the current height (0 ~ 255), mining in the 11 floor height is the best

5. As a blockchain researcher, many new people often ask this question. In fact, there are two main ways to invest in bitcoin. The first is to buy bitcoin directly from the corresponding digital currency exchange; The second is to mine for bitcoin

first of all, mining is the main way to obtain bitcoin, but the current threshold of mining is relatively high. If you choose to mine by yourself, first you need to understand certain technology, then download the bitcoin client and mine by yourself according to the online bitcoin mining tutorial
however, in theory, bitcoin can still be mined with computers or graphics cards. However, e to the development of mining instry in recent years, the whole network computing power of bitcoin is extremely terrible (more than supercomputers), so if you want to mine with computers or graphics cards, you can't find bitcoin, If you want to dig bitcoin, you still need to buy mining machines. Now the better mainstream mining machines in the market have to be tens of thousands. Of course, there are cheap second-hand mining machines, but these second-hand mining machines are all obsolete ones, and the electricity cost of mining is relatively high

in addition to the second way of direct purchase, the digital currency exchange is a special place for bitcoin trading. If you want to own a bitcoin, you can buy it directly with money. However, it should be noted that there are many digital currency exchanges in the market at present. Many small exchanges are specialized in cutting users and eating customer losses for a living. Therefore, when choosing an exchange, it is better to focus on the head exchange. For example, Hufu, one of the head exchanges in China, I have been using it for nearly two years, and it is very stable and safe.

Mining: that is, bitcoin mining, is a process of using computer hardware to calculate the location of bitcoin and obtain it

3, users use personal computer to download software, and then run specific algorithms. After communicating with remote server, they can get corresponding bitcoin, which is one of the ways to get bitcoin. Ordinary graphics cards don't need to try, and electricity charges are not enough. Master Lu has bitcoin test, which can see how long it takes for your computer to dig a bitcoin

7. Are you talking about virtual currency
if it's virtual currency, what kind of currency do you want to dig, BTC or eth, LTC or big zero? Different currencies, different algorithms, the corresponding mining machine will be different, the price will be different (the size of computing power, different brands, the price will be different)
if it's traditional: I don't understand.

8. In recent years, Oracle is just in the middle of the release of Oracle database procts. Now Oracle 12.2 comes with important innovative features. Oracle will soon be fully assembled, from centralized storage to sharding distributed architecture, from IOE mode to IE distributed storage architecture, from in memory database to column storage compression, from relational mode to bigdata SQL, Oracle this will be the most important proct release, insight into the core of the database, do in Andrew's Secret theme.

9. Reliable information has been obtained that it will not be listed on October 8, 2018, saying that it will only be listed in 2019, and that it will continue to cheat money by delaying the time.
