Panda D3 video card miner

1.

bitcoin was obtained by CPU in the early days. With the continuous development of GPU speed and the emerging advantages of GPU general computing, 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

advise the landlord not to dig up if the budget is not too much!!! This money is not earned if you want to

the difficulty of bitcoin is increasing. Mining with graphics card is a race against time. The main reason is that the difficulty of mining bitcoin is graally increasing (the reason of bitcoin algorithm design). If a set of platforms can get 1 bitcoin per day according to the current difficulty, then in one month, the platforms with the same computing power will only get 0.8 bitcoins, even the top graphics cards will get 18.2 days (which can't be shut down), and the lowest second-hand hd7750 will need more than 400 (it will take 214 days to get one). Just look at this figure (this is the data in May this year, Now it's more than 18 days)

people can earn money by buying several mining machines (mining machines with dozens of top graphics cards piled together)

I hope I can help you

2. Look at the computing power, graphics card, price and warranty. Pay attention to whether it is renovated. Panda mining machine is famous. You can have a look

3.

I recommend two: ant G2 graphics card miner, panda B3 plus graphics card miner

ant G2 graphics card miner is used to mark panda's B3 plus graphics card miner. In terms of computing power, they are almost the same. On the one hand, they use the vest card, and on the other hand, they use the rx470 without the vest, both at 220mh / s

4. Can't add video memory
if you want to upgrade, you can only replace the graphics card with 8g memory.

5. If you want to sue, you must have evidence to prove who owes you money and that he is in breach of contract and does not repay.

6. The international financial system is a very complex system. In a broad sense, its constituent elements almost include the whole international financial field, including: international exchange rate system, balance of payments and international reserve system, coordination of national economic policies and international economic policies, etc. But in a narrow sense, the international financial system mainly refers to the international monetary arrangements, including: international exchange rate system, balance of payments and international reserve system, coordination of national economic policies and international economic policies.

7. Ten thousand yuan is one centimeter, and that one million yuan is one meter thick.

8. Yes, Tianyi electron & RLM; Quotient & RLM; Business & RLM; There are & RLM; Limit & RLM; Public & RLM; The company not only has efficient systems with high concurrency and low latency, but also has a wide coverage of small and medium-sized & RLM; Precision and flexibility of enterprises & RLM; Put & RLM; In fact, it's not just blockchain enabling & RLM; Enterprise & RLM; Instry & RLM; Gold & RLM; In this respect, this & RLM; All aspects of the enterprise are developing very well. The future is promising.

9. There are security risks in using free WiFi in public places, especially when being "fished". For example, when users use phishing WiFi, hackers can intercept and crack your information through WiFi, so as to steal your personal information and account password. They can even make you automatically run remote control, Trojan horse and other malicious programs when browsing web pages through ARP deception, hanging horse and other means, causing greater losses. Therefore, try not to use WiFi with unknown source, Especially free WiFi without password.
