What's the sum of the calculation power now
At present, bitcoin needs to be g by professional mining machines. The global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin
according to the current speed and the number of bitcoins, it will take three months to get a bitcoin if a computer is kept in a 24-hour state of operation
extended data:
because the current bitcoin mines use special bitcoin mining machines to mine. The computing power of an ant S9 miner is 13.5th/s, which is equivalent to the sum of the computing power of 7500 1080ti graphics cards. A medium-sized mine has hundreds of such miners
the instry of bitcoin is not very good either, so you'd better not dream of becoming rich overnight with bitcoin. Now many countries have issued policies to suppress the rise of bitcoin prices. Some countries even refuse to dig bitcoin. Many bankers and economists are disgusted with the emergence of bitcoin

customization, aiming at scene segmentation: different instries have different proction systems, and each enterprise needs its own specific application scenarios. In other words, if you want to land, edge computing needs to be configured according to different conditions and operating environment to support a variety of instry scenarios. Such a set of computing resources can be quickly copied to various places to meet the needs of edge computing. In addition, there are meteorological forecasting, agricultural remote sensing, environmental monitoring, medical image analysis, etc. These customized and subdivided scene computing power output can be realized in the tenth power computing power bank
performance of independent processing chip: usually, after receiving data, edge computing needs to process the data independently. If the chip performance is insufficient, it cannot process. For example, in the smart city scenario, there will be additional demand for computing power and storage in proct design, so the support of GPU card, PCI slot and SSD needs targeted design.
2. For indivial stocks with obvious bottom period, the author's experience is that the daily trading volume in the bottom period is multiplied by the bottom operation time, and then the position of the banker can be roughly estimated. The position of the banker = the bottom period × Proactive buying (ignoring retail buying). The longer the bottom period is, the larger the market position is; The more initiative buying, the more money the banker will take. Therefore, if investors observe the bottom of the long-term horizontal consolidation of stocks, usually for the silent absorption of funds, the main force in order to rece the purchase cost, so high sell low and constantly clean up short-term customers; But there is still a small part of long-term funds involved. Therefore, ring this period, the main force of the goods, at most, only reached about 1 / 3-1 / 4 of the total volume. Therefore, ignoring the initiative of indivial investors' buying volume, the buying volume can be settled as the total trading volume × 1 / 3 or total volume × 1 / 4, formula 2 is as follows: banker's position = stage total turnover × 1 / 3 or 1 / 4, for the sake of caution, lower quantity can be confirmed
3. In the low position, the stocks with active transactions, high turnover rate, and little stock price rise (set the standard as stage rise less than 50%, preferably less than 30%) are usually the investors. The greater the turnover rate, the more sufficient the main fund-raising. Investors can focus on the stocks whose "price" temporarily lags behind "quantity". The author's experience is that the turnover rate takes 50% as the base. Every time it goes through multiple stages such as 2, 3 and 4, the stock price trend will enter a new stage, which also indicates that the position of the banker will change. There are three formulas to calculate the position of the banker by using the turnover rate: the overall stock flow × Turnover rate of indivial stocks in a certain period - turnover rate of the whole market in the same period); The practical significance of this formula is that the amount of the main capital's purchase volume (that is, the average purchase volume) exceeding the market turnover rate is usually the intervention of the foresight capital, which is generally applicable to the long-term decline of the unpopular stocks. Therefore, once the main force continues to absorb the unpopular stocks, we can relatively easily measure and calculate the position of the main force
~ the easiest way to find the lowest price in the last 30 trading days. Then look ahead for the K-line with the largest turnover, turnover rate greater than 10, the longest shadow line and cross shape, and then take the average price of the day before and the day after, which is basically close to the recent main cost. This move is very practical, no need for professional calculation, suitable for beginners to use.
no matter where you go to the center, you'd better look at the road signs. It's safer to take a bus to the bus station. Just ignore anyone who talks to you.
as for going to the center of the city, it depends on where you think it's the center of the city. Nearby Tianhe City, Shangxiajiu road and Beijing road can be regarded as the prosperous center of the city, It depends on where you want to go
1. Take Metro Line 1 from the sports center, pass 2 stations, and then arrive at Yangji station
2. Take Metro Line 5, pass 5 stations, and finally arrive at the boarding station of Guangzhou railway station This data comes from the network map, and the final result is subject to the latest data of the network map
