Shenzhou 3060 notebook mining computing power
at present, the computing power of bitcoin in the whole network has reached 2.36 billion hash collisions per second, which is equivalent to the number of water droplets in more than 200000 50 meter long standard swimming pools. But even with such a large amount of computing power, it will take about 10 minutes to hit a hash value that meets the requirements
in 2012, bitcoin's output was halved for the first time, and in July 2016, bitcoin's output was halved for the second time. At present, 12.5 bitcoins are awarded for recording one page of account book. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, with a total of 21 million. In other words, the difficulty of digging bitcoin is increasing, while the time required is increasing
are you still thinking about mining these days? This is not the year of 2010. Now, don't think about making money from small-scale mining, unless you have a multi million investment. Now, it's large-scale mining with mining machines, and professional management of the whole computer room. Now, there are several ways for personal investment. 1. Buy BTC by yourself. 2. Futures trading. 3. See ipo4. It's hard to get back the capital even if you buy butterfly mining machines by yourself. According to the current price and difficulty of mining machines, mining machines are generally expensive It takes three months to get back the capital (not including electricity, but only mining machine money). But don't forget that the difficulty has been increasing, so you can't get back the capital in your personal mining life. A better way is to buy the power stock through IPO. If you don't say that, you can talk to me about mining teaching as follows http://cnbtcnews.com/bitcoin-study/what-is-bitcoin/bitcoin-from-beginner-to-master.html
Graphics cards can't dig out bitcoin right now. Your calculation power is the calculation power of Ethereum. The calculation method is also wrong
You can refer to the following, according to some commonly used graphics cards in the Internet bar market, sort out the price and calculation power of a related graphics card, as well as the expected return to the current period, It can be used as a reference:
{rrrrrrr}
power consumption: 243w
computing power: 22.4m
price of graphics card: 1999 yuan
quantity of eth g every 24 hours: 0.015
revenue generated every 24 hours: 24.48 yuan
expected payback time: 81.66 days
power consumption: 159w
computing power: 24.3m
price of graphics card: 1599 yuan Yuan
number of eth g every 24 hours: 0.017
revenue generated every 24 hours: 27.9 yuan
estimated payback time: 57.31 days
total power consumption: 171w
computing power: 24.4m
price: 1999 yuan
number of eth g every 24 hours: 0.017

Video card (graphics card) full name display interface card, also known as display adapter, is the most basic configuration of computer, one of the most important accessories. As an important part of the computer host, the graphics card is the equipment of digital to analog signal conversion, and it undertakes the task of output display graphics
the graphics card is connected to the main board of the computer, which converts the digital signal of the computer into an analog signal for the display. At the same time, the graphics card still has the ability of image processing, which can help the CPU work and improve the overall running speed. For those engaged in professional graphic design, graphics card is very important. Civil and military graphics chip suppliers mainly include amd (ultra micro semiconctor) and NVIDIA (NVIDIA). Today's TOP500 computer, including graphics card computing core. In scientific computing, graphics card is called display accelerator
web link post bar example:
we will calculate the graphics card to dig bitcoin earnings
assuming you are HD 7950 awesome, according to Zhongguancun online information, approximately 500MHashs/s
HD 7950 is g to compare the power of the graphics card, calculate 500MHashs/s, converted to 0.5GH/s. I am your current graphics card, you don't need to buy it
the full load power consumption of HD 7950 is 210W, the graphics card mining is full load work, and the electricity charge is 0.6 yuan / kWh
I reckon that you have been digging for 180 days in a row, that is, half a year, 24-hour power on. You should pray that your computer will not hang up because of this
difficulty coefficient: the difficulty of bitcoin has been increasing. Generally, the calculation is increased by 30% in 11 days. I'm a little less. It is increased by 25% in 11 days
OK, all the parameters are ready, calculation
in calculation...
eh, how come it's a negative number
because you need to pay the electricity bill for your graphics card
and there is no bitcoin output every day, because your computing power is too low
suppose your graphics card is HD 7950 and the computing power is 0.5gh/s
at present, 200g ASIC mining machine is on the verge of elimination, because 3T mining machine is already looming in the market
but even the 200 g miner that is going to be eliminated is 4000 times of the 0.5 calculation power of your HD 7950
the World Gold Council (WGC) claims that the US Federal Reserve's interest rate increase may not have the adverse impact on gold price as many people think
the relationship between gold prices and interest rates is more complex than it appears and more fragile than in the past, the World Gold Council said in a report on Thursday
the association added: "other factors affecting the price of gold, including some positively correlated with economic growth, emphasize that gold is an important diversified asset and a portfolio asset for risk management. This role is becoming increasingly important as stocks and bonds are likely to provide below average returns over the next few years. "
in the past 12 months, market speculation on when the United States may choose to raise interest rates has been fierce. Since 2008, the Federal Reserve has kept the federal funds rate close to zero
although the Fed was initially expected to raise interest rates for the first time in a decade in June this year, a series of mixed economic data, low inflation rate and dovish comments on the US economic growth rate issued by Fed chairman Yellen delayed the schele of raising interest rates
when the federal funds rate really rises, the general consensus is that the price of gold will face heavy downward pressure, because the planned cost of holding gold will rise, thus prompting investors to turn to assets that provide income
the World Gold Council said: "however, jewelry and technology demand accounted for nearly 60% of the annual demand for physical gold. There is an indirect positive relationship between these markets and interest rates, that is, the periodic rise of interest rates is usually accompanied by the increase of economic growth and consumer spending
according to the World Gold Council, Europe and North America account for only 17% of global gold demand, and only 60% of it is related to investment
similarly, the view that US interest rate hikes affect gold prices is not as strong as before, because this situation is largely based on the market's analysis of the performance of gold prices and interest rates between the 1970s and 1980s. At that time, the economy was very different from what it is now
according to the World Gold Council, "the gold market is also different. Over the past decade, demand for gold in developed markets has fallen from more than 60% in the 1970s to less than 30%. Emerging market demand for gold accounts for 70% a year and is less sensitive to changes in US interest rates. In addition, the demand for jewelry and technology is largely Pro cyclical. "
in terms of investment demand, gold will continue to be a diversified asset
the World Gold Council said: "even when the nominal interest rate rises to 4%, gold has been quite effective in diversifying its portfolio and recing the risk of real interest rate."
according to the world gold association, the current real interest rate level in the United States is still very low and far below the threshold level. As of December 31, the real yields on three-month and one-year treasury bonds were - 0.73% and - 0.6%, respectively
the association said: "raising interest rates will not improve the outlook for fixed income assets. At the current yield level, the rising space of bonds may be limited, so it is not as effective as gold in easing equity risk. This helps to boost demand for gold, as some investors will use gold to supplement bonds when managing equity risk and diversifying their portfolios. "
