Dismantling of T2T mining machine
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

labor distribution rate = labor cost / added value of instrial enterprises
personnel cost rate = labor cost / sales income
average labor cost = labor cost / number of employees
labor cost output coefficient = added value / labor cost
labor cost sales income coefficient = sales income / labor cost
labor cost content = labor cost / total cost
labor cost wage content = labor cost Total capital / labor cost
total labor proctivity = added value of instrial enterprises / number of employees
T2T belongs to the concept of vertical category, which is a way of expression of network services and the definition of a kind of similar service website. T2T directly completes the end-to-end demand service from the demand of trainees to the supply end of ecation and training schools through channels
foreign name: training to training
Chinese Name: training to training
OTC (over-the-counter market), which refers to the equity trading in the market outside the stock exchange. The establishment of counter trading market in China can provide equity trading platform for millions of enterprises that can not meet the listing conditions, which is concive to the development of small and medium-sized enterprises and the formation of a multi-level capital market in China. Over the counter market in English and over the counter market in Chinese. The term OTC market originated more than 100 years ago. At that time, there were many securities not traded on the New York Stock Exchange and other stock exchanges in the U.S. stock market. Investors could buy these stocks through securities companies or banks. At that time, investors were only able to buy and sell stocks on the counter of the market department opened by securities companies and banks, so the counter market and counter trading got their names

It solves the end-to-end mutual demand, realizes the ecation and recognition process from primary demand to selective consumption, and realizes the integration of marketing demand and marketing channel of supply end (training institution)
T2T directly breaks through the traditional concept of time in off-season and peak season of ecation and training institutions, and solves the problem that students' learning needs in off-season can not be solved, and the loss of ecation and training institutions in off-season can not be reversed
the direct revolutionary significance of T2T to the ecation and training instry is to balance the end-to-end supply and demand as well as the profit and loss in the low and peak seasons. T2T has just started, and there are not many T2T mode platforms in the instry to provide services
because it meets the different needs of students (consumer side) and schools (supply side) at the same time, it forms a direct solution based on the ecation instry, so the value of T2T itself is immeasurable in the field of ecation and training and in the vertical instry
secondly, the scale of ecation and training market has reached 300 billion yuan, and the cake is so big that gold is everywhere. Based on the pressure of social competition, the future development prospect of the whole instry is still bullish. However, the scale of 300 billion yuan is currently based on a traditional supply and demand marketing channel, which accounts for the main proportion of revenue. Therefore, as a complete solution of network channel, T2T is bound to set off a marketing and revenue storm in the vertical instry of ecation and training in the future. As T2T is a service platform for end-to-end (training institutions and schools) solutions, it is bound to result in a revenue model within the platform. At present, PPC (pay per call) is mainly used in the way of effective telephone billing revenue, so the number of signed marketing end (training institutions and schools) and effective telephone will directly determine the life and death of T2T platform operation. Lack of effective telephone and too few contracted marketing terminals will not be enough to maintain operating costs
therefore, more ways of revenue is the primary problem to be solved by T2T. Simple network - ecation and training channel, network has ah life - ecation and training channel, life information website. Its channel mode conforms to the characteristics and definition of T2T
T2T, or trade to trader, is a new e-commerce mode of trader to trader. The emergence of T2T is a more advanced and broader e-commerce mode based on the original B2B, B2C, C2C e-commerce mode. The emergence of T2T is also accompanied by the emergence of e-commerce mode.
