1. At present, only a few algorithms of virtual currency are meaningful, such as XPM (prime currency, used to solve prime numbers), GRC (Greider currency, used for scientific operation), etc. I have been using CPU to dig XPM, although my income is limited. In fact, these currencies also have the excellent properties of bitcoin, but they are not favored by most virtual currency lovers. The price is very low, which is really distressing.
2. 1. CPU is mainly optimized for serial instructions, while GPU is optimized for massively parallel operations
2. Modern multi-core CPU aims at instruction set parallelism (ILP) and task parallelism (TLP), while GPU is data parallelism (DLP)
3. GPU often has a larger bandwidth of memory, that is, the so-called video memory, so it will also have good performance in high throughput applications
4. CPU is a general-purpose operation. In short, it means brainless calculation and violent calculation. Whether it's 100 children sharing apples or simulating the earth, it can be decomposed into the most basic calculation of 1 + 1 = 2. GPU is specially designed to deal with high-order mathematical algorithms, such as calculating the relative positions of light source, object, viewpoint and shadow, which requires trigonometric functions to be piled up. The bitcoin digger uses SHA-256, a secure hash function invented by the US National Security Agency, which is generally used for password encryption and decryption. This algorithm can perform a large number of 32-bit integer right-rotate operations, which is very suitable for GPU which is good at large-scale concurrent computing and password cracking.

3. I tell you, the computing power of home PC is too low. According to the difficulty of more than 900 million computing and programming, the computing power of a home PC is generally between 100 m and 600 m. if you dig, the money you earn in a month is not even one tenth of the electricity bill, so you need a mining machine. Now on the market, the machine specially optimized for the calculation algorithm of the generation of bitcoin is the miner. A miner can process 600ghash data operations per second. Without interruption, it can generate a bitcoin in about 10 days, which requires high computer configuration
it's not impossible that you can dig 100 in a day. To be exact, it doesn't take a day. It only takes less than a few seconds to win. The premise is that you can win "Tianhe No.2" which ranks first in the world.

4. The blockchain games I know include eth90 games and DAPP games, which are very famous blockchain games.
5. Bitcoin mining is a process of using computer hardware to do mathematical calculation for bitcoin network to confirm transactions and improve security. As a reward for their service, miners can get the Commission included in the transaction they confirm, as well as the newly created bitcoin. Mining is a professional and competitive market. The bonus is divided according to the amount of calculation. Not all bitcoin users mine, and it's not easy to make money from mining
the popular point is to use the computing power of your computer to solve mathematical problems, and then give you a certain amount of bitcoin in return
bitcoin mining has gone through three stages, CPU, GPU and ASIC
. At present, bitcoin mining needs professional ASIC mining machine. At present, Avalon and butterfly laboratory are more famous mining machinery manufacturers in the market, but American butterfly laboratory likes to evade tickets. Avalon has proced the world's first ASIC miner. At present, Avalon's third generation chips have been put into the market, and avalon3 miner is about to enter the market.

6.
Bitcoin is actually a useless string of numbers, but it is recognized as useful, just like diamonds, antiques, calligraphy and paintings, game skin and so on. They can't be eaten or used, but we will recognize their value
"mining" just allows more people to participate in the construction of blockchain network. Is it really good that so many electricity charges are used to "calculate" a series of virtual values? Bitcoin is not a hedge. The price of bitcoin fluctuates greatly. Speculation on bitcoin may become rich overnight or become poor overnight. Bitcoin is not as safe as it claims. In 2014, the world's largest bitcoin trading website, mtgox, was hacked and went bankrupt, and the $467 million worth of bitcoin evaporated instantly. Criminals use it to launder money, evade taxes and so on. It is also quite difficult for the government to investigate. The above personal opinions are welcome to be criticized and corrected. Agree with me, please click like before you go, thank you! Like me, please pay attention to me, thank you again
7. The overall principle is that the stronger the computing power is, the larger the proportion of bitcoin can be allocated. However, the speed of bitcoin generation is graally decreasing
technically speaking, it is completely feasible, because the algorithm is not complex and can be transplanted to the mainframe with a little modification. If it can be optimized for parallel computing, it will be more efficient
but in terms of cost, supercomputers are not cheap to use. Only a medium-sized and large-scale computer consumes tens of thousands of power every day, not counting the loss of the whole machine. As for supercomputers like Tianhe-1 and tianhe-2, the research and development costs and rental costs are still relatively high. Whether the excavated bitcoin can recover the cost still needs to be carefully considered.

8. No, bitcoin is generated by P2P nodes. The reason why it is calculated is that it uses cryptography instead of being generated casually. Because P2P is limited, so the number will not be very large, the operation is not created, but found.
9. January 13) is a milestone for cryptocurrency. 16.8 million bitcoins, or 80% of the total bitcoin supply, have now been mined. This means that the mining of bitcoin miners has become more and more difficult. What's more, governments of many countries have taken the opportunity to strengthen the crackdown on bitcoin "mines"
the total number of bitcoins is 21 million. As of January 13, 2018, 16.8 million bitcoins have been mined in the world, with 20% left, that is, 4.2 million bitcoins are waiting for everyone to excavate, facing the situation of "more than enough"
in November 2012, the new issue speed of bitcoin was reced to 25 bitcoins per block
bitcoin mining relies on the use of computer chips to calculate specific encryption algorithms. With the increasing scarcity of remaining bitcoin resources, the mining cost of a single bitcoin is also increasing. As long as the function of supercomputer is completely based on a specific encryption mathematical algorithm. Changes in bitcoin are soon over. And the time is very short.
