What does HM mean
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. 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 amount 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
mining machine is a tool for procing and mining bitcoin
however, you really regard mining as fun and entertainment. If you don't care much about whether you can dig, you can also let your own machine dig all the time. However, the machine configuration above you should not be low, but it is not suitable for mining, just as the swimming champion is not necessarily good at mountain climbing
generally speaking, mining machines mainly focus on graphics cards, which have little to do with processors, main memory boards and hard disks. Of course, they need to be stable and not crash for a long time. In fact, a card is more suitable for mining. In principle, you can go to the network. It is said that before the emergence of R-Series a card, the card with good mining effect was not hd88708750, But we despise the old graphics card that has been eliminated
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
