Bitcoin graphics computing power

1.

21.5 * 3600 seconds * 24 hours = 1857600 M / day
1857600 / 1024 / 1024 = 1.7715 T / day
a t of computing power / day can dig bitcoin worth 4.03 yuan
1.7715 * 4.03 = 7.14 yuan / day

since 2017, bitcoin has reached new heights. Yesterday (May 23), the value of bitcoin broke through the ￥ 16000 mark, hyping virtual currency, becoming a matter that the general public can participate in, And a little bit of technical level, both fried money, but also began to have the technical content of mining

as we all know, virtual currency has a numerical peak, the more difficult it is to dig. In fact, it's hard to judge whether to lose money or not if we continue to dig. Therefore, in the end how to dig, dig what can be the fastest back to this, this paper studies the above two core issues based on the current market situation

2. After high-speed computing with the computer composed of AMD graphics card, bitcoin can be generated
1. Unlike most currencies, bitcoin is not issued by a specific monetary institution. It is generated by a large number of calculations based on a specific algorithm and is a virtual currency
2. In order to get bitcoin, you have to use computing machines, many of which are provided by AMD graphics card with high computing power. When bitcoin was hot, AMD's graphics cards were always in short supply, such as HD 7850, HD 7870, HD 5850, HD 5870, R7 270, R 280x, which are the best helpers of bitcoin
3. Later, when someone invented a mining machine that could get bitcoin more quickly, these graphics cards slowly withdrew from the mining stage
in other words, the computer made up of AMD high-speed graphics card was once the main platform for acquiring bitcoin. This is the relationship between them.

3. The use of high-end amd graphics card, but the era of graphics card mining has come to an end, has entered the era of ASIC mining. Now, bitcoin can't be found with graphics card, because the computing power is growing too fast, and the difficulty of mining has exceeded 40p. At present, even the professional ASIC mining machine is difficult to profit, because the chip update speed is too fast. The first generation ASIC miner's chip basically adopts 130nm process, the second generation adopts 55nm process, and the third generation adopts 28nm process. But at present, there are not many 28nm mining machines, and most manufacturers just regard it as a slogan, and the high performance of the chip does not represent the overall high performance of the mining machine. Avalon delivered the world's first ASIC miner. The computing power of the second generation chips once accounted for one third of the total network computing power. At present, the third generation chips have been released.

4. < UL >

the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it

bitcoin is a kind of P2P digital currency

bitcoin is not issued by a specific monetary institution. It is generated by a large number of calculations based on a specific algorithm. 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 number of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million

this virtual currency only needs the computing power of the computer, and it has no technical content. Basically, it only needs to hang up to "generate" bitcoin, and bitcoin can be traded at any time, so as to transform it into real currency

if you want to get bitcoin, you need to download the special "mining software" and set it to start

In general, the computing power of GPU is much higher than that of CPU, and even the entry-level graphics card is much better than the top i7 series. So it indirectly tests the performance of the graphics card

5. Your input-output ratio is too low. If you really want to speculate, you can find a professional platform to trade, buy and sell freely. I'm trading in okex, a regular platform, with a very good experience. Did my answers help you? If so, please accept

6. There's a mistake upstairs. Bitcoin came out in 2009. How could bitcoin mining machine be 7 or 8 years old

now, of course, there are still people mining. There are about 21 million bitcoins in total. At present, there are about 13 million bitcoins in the world, and there are 8 million left. However, now mining is basically large-scale integrated mining machine, and the era of graphics card mining ended at the end of last year, because with more and more bitcoin being g out, the difficulty of mining is increasing automatically, and large-scale mining equipment is manufactured in batches, resulting in that the computing power of graphics card can no longer generate positive benefits
for example, the current mining difficulty is 16818461371, and the computing power of a better graphics card such as ati5970 is 800mhash / s. It takes 2863 years to dig out a bitcoin. The computing power of the large-scale integrated miner can reach 2tash / s, and it will take more than a year to dig out a bitcoin. There are many manufacturers procing this kind of large mining machine all over the world, and the computing power is still improving. Only this kind of equipment has been put into use for more than 100000.

7. This is definitely a loss.
recently, I saw a test that the rtx3070 notebook only earns 1.2 yuan an hour.
1050ti computing power is less than 1 / 4 of 3070, which is about 24%
power consumption is 35% of 3070.
energy consumption is not cost-effective. One hour's income is definitely less than 1 yuan, except for the electricity charge. Once the loss of notebook is eliminated, it is definitely a loss
