1. bitcoin was acquired by CPU in the early days, e to different working methods. CPU is mainly to do full-function operation, the number of core is small, and the operation ability is limited (GPU is a very large number of operation core for special operation). With the advantages of GPU general computing and the continuous development of GPU speed, miners graally began to use GPU instead of CPU for mining. Bitcoin mining uses SHA-256 hash operation, which will carry out a large number of 32-bit integer cyclic right shift operation. Interestingly, this algorithm operation can be implemented by a single hardware instruction in AMD GPU, while it needs three hardware instructions to simulate in NVIDIA GPU. This one alone brings an additional 1.7 times of computing efficiency advantage for AMD GPU. With this advantage, amd GPU is favored by the majority of miners. At present, it has left GPU computing. At present, miners have begun to widely use integrated circuit (ASIC) mining machine. Although this kind of mining machine can only be used to dig bitcoin, other currencies can not be used yet, but a single mining machine can reach the level of megabytes, especially loved by mine owners in Sichuan, Guizhou and other regions. Tens of thousands of professional mining machines are in full swing, and retail investors are unlikely to get bitcoin in the face of such powerful computing power.
2. Compared with CPU, GPU computing will have an absolute advantage in bitcoin mining
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
the CPU needs strong generality to deal with various data types, and at the same time, it also needs logical judgment, and it will introce a lot of branch jump and interrupt processing. All these make the internal structure of CPU extremely complex. GPU is faced with highly unified, interdependent large-scale data and pure computing environment without interruption. GPU uses a large number of computing units and ultra long pipeline, but it only has very simple control logic and saves cache. The CPU not only occupies a lot of space by cache, but also has complex control logic and many optimization circuits. So unlike CPU, GPU is good at large-scale concurrent computing, which is suitable for password cracking
in short, 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. This is legal in some countries, and the domestic attitude is not very clear. Anyway, it is not illegal
4. Now it's not enough to dig bitcoin electricity bills with graphics cards. It is impossible to work at full load all day without damage.
5. This level of mining is not enough. The monitor is not worth 500 yuan
6. Don't dig this video card. You can't get one even if you dig it for a few months. The electricity and Internet charges are enough for you. It's not worth your life to pay for the dead
7. There must be damage.. Mining is overdraft graphics card.. If you're not lucky, it's possible that the graphics card will break in two days~
8. It's normal that businesses are not charities, and no one does business at a loss
a small program is an application that can be used without downloading and installing. It realizes the dream of "within reach" of the application. Users can open the application by scanning or searching. It also reflects the concept of "go as you go", so users don't need to care about whether to install too many applications. Applications will be available everywhere, but no need to install or uninstall. For developers, the threshold of small program development is relatively low, which is not as difficult as app. It can meet the needs of simple basic applications, and is suitable for the conversion of life service offline stores and non rigid low-frequency applications. Small programs can realize seven functions, such as message notification, line scan code, official account number, etc. Through official account, users can jump between official account and small program. Because the applet does not have an entry.

9. Now mining can't work. It's much more practical to hang YY. Mining burns graphics card very much. Bit can't work now,
