Evaluation of core T2 miner
Publish: 2021-05-16 21:11:58
1. There are many kinds of mining machines in the market, and the currencies they dig are different. bitcoin machines are the most. From Shenma m3 and ant S9 to many computing power machines, customers have more choices. The computing power is getting bigger and bigger, and the price of machines will rise correspondingly. There are many small currency machines coming out, so if you are just starting to contact this instry, You can choose a BTC digging machine with high cost performance, and buy one or two back as a reference. If you suggest, you can choose ant S9 or core T2T, with computing power of more than 10 t to 30 t, and the price is less than 1000 yuan
2. OK. It's not as complicated as you think
3.
At present, the mining machinery is in a state of two-level differentiation, such as the better ones: the interstellar Aoyun, ants, and Xindong are all OK, and the interstellar Aoyun focuses on IPFs. In addition, some other mining machine chip enterprises are also faced with challenges. In addition to the main mining machine chips, they have begun to layout and promote the artificial intelligence business to expand new possibilities
4.
Taking t2t-30t as an example, the calculation force of t2t-30t is 30t, and the power consumption is 2200W, that is, 2.2kW. The power consumption of a single miner in 24-hour operation is 2.2kW * 24 = 52.8kwh, and the electricity charge is once calculated as 0.56rmb, the daily power consumption cost of a single miner is 52.8kw * 0.56 = 29.57rmb
to "mine" with bitcoin mining machine, if the graphics card is fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. There are many professional mines at home and abroad in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even some people in a residential area in Yunnan carried out crazy mining, which led to a large area trip of the residential area, and the transformer was burned
extended data
mining principle of bitcoin mining machine:
bitcoin mining and node software mainly initiates zero knowledge proof and verification transactions through point-to-point network, digital signature and interactive proof system. Each network node carries out broadcast transactions to the network. After these broadcast transactions are verified by miners (computers on the network), miners can use their own work proof results to express confirmation. The confirmed transactions will be packaged into data blocks, and the data blocks will form a continuous data block chain
every node of bitcoin will collect all the unconfirmed transactions and gather them into a data block. The miner node will add a random adjustment number and calculate the sha256 hash value of the previous data block. The mining node keeps trying again and again until the random adjustment number it finds makes the hash value lower than a specific target
5. A9 is still considerable in terms of current revenue. Now it's about 620 yuan a day. Because the income of the first group of miners who used this mining machine to mine is still stable, and the initial income is also 550-650 up and down. The price may not fall, but will rise. Now the currency price is rising steadily, driving the price of mining machinery is also rising. There is also a serious shortage of cash on the market
6. If you dig, now the mining machines are all assembled by yourself, and there is no one specially selling mining machines. Taobao should have, but the performance is very poor, do not recommend directly buy the whole chicken, or recommend you self-assembly.
7. R9380x single card computing power 20 is 16.83 per day according to today's 1800
the mining price is a little low these days, and the fluctuation range is very large
the mining price is a little low these days, and the fluctuation range is very large
8. App development refers to focusing on the development and service of mobile application software. App is the abbreviation of application, usually refers to the application software on the mobile phone, or mobile client. In addition, there are many online app development platforms. App development refers to focusing on the development and service of mobile application software. App is the abbreviation of application, usually refers to the application software on the mobile phone, or mobile client. Apple's app store has opened a new chapter in the development of mobile software instry, making the enthusiasm of third-party software providers to participate in it unprecedented. With the increasing popularity of smart phones and the increasing dependence of users on mobile software stores, the market demand and development prospects of app development are also graally booming. As of December 2012, app development has become a red sea market. Four main systems: 1. Apple IOS system version, the development language is Objective-C; 2. Microsoft Windows Phone System Version, the development language is C #; 3. Android system version, the development language is Java; 4. Symbian system version, the development language is C + +.

after confirming the content of human resource cost items, we should choose a certain measurement basis and method to quantify the human resource cost. According to the different characteristics of human resource cost items, we should add the expenses involved in each item directly or by calculation. It will not be explained in detail here. Human resource cost accounting is divided into account setting, account processing and financial report. In terms of account setting, human resource itself is a special resource, which determines the characteristics of human assets different from other assets, so account setting is different from the account setting of cost items in traditional accounting. It mainly includes the following subjects: human assets, human resources, acquisition cost, human resources development cost, human resources guarantee cost, human assets expense, human assets amortization, human assets loss preparation, human assets profit and loss
