7950 computing power
as a middle-aged miner for 13 years, let's talk about the feeling of mining before.
I bought four mining machines in the past. bitcoin uses CPU and I'm not familiar with it, so I use the form of buying graphics card to dig Wright's coin.
the first one is a simple double card mining machine, not a mining machine strictly speaking, but a double 7950 machine, At that time, I thought about digging for a while. If I didn't make money, I could still play games by myself. As a result, I found that the efficiency was really not high. Later, I used to dig some dog money and play with it.
the second one was the popular 6-card miner in those years. At that time, there was a powerful motherboard, which could run for 6 yuan by connecting with the PCI adapter and changing the BIOS. At that time, I could dig a lot of Wright's money every day with this machine, It's a pity that there are too many people digging, so it took more than 80 days to dig the coins. The third and the fourth are professional mining machines. At that time, the new chips were used to mass proce mining machines. Although they were expensive, the power consumption decreased a lot. It took about a year to dig, In the end, he retired, g up other counterfeit coins for a while, and then sold them.
generally speaking, many websites have no credibility at all in the past few days. They actually know what the concept of excessive increase in computing power is after digging up the money.
when ZF suppressed it, the assets immediately shrank by nearly 70%, but they still didn't sell because of their faith, On the contrary, after selling the miner, I bought some coins and put them in my hand. When I bought 100, I g them and only bought 15. Hey, the miner was sealed and put under the bed. After waiting for three years, I found that it rose again. This year, when bitcoin rose to 2W, I sold some Leyte coins and paid the down payment. Almost 300 of them were sold. Now it seems that the highest is 380, Ha ha
now I still have some money in my hand, and I plan to hold it for a long time, but I won't dig any more. However, I still have a lot of orders with our first-class suppliers. In the past two months, I sold nearly 150 cards, and the more I sold, the more I sold. Some cards are about to double, which is even crazier than that in 2013, The existence of e-money has its own value in the end, but it does not deny that there are so many speculators who come in to fight. There are indeed those who pursue the price. After the boom, there will be a wave of leeks cutting. In the final analysis, bitcoin is just an investment. Everyone feels different about the risk. The strength of big funds is still strong, and it is inevitable for retail investors to be cut, But it's better than A-share at least.
mining is not a good thing. The big miners are in the remote areas with low electricity charges, many mining machines and low cost. Most people dig at home, and that's just a little fuss.
finally, it's not a good thing to grow too fast. Those who are confident can come in and show their operation. If they don't have much ability, don't come in, Only by routine
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
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
now trading makes money quickly. Go to bitcoin China and other platforms to trade. Search btc123. It's very comprehensive here.
RMB will continue to depreciate. The current price of US dollar against RMB is 6.7572. In the future, it will be 6.9000 and 7.1550, or even 7.42 or higher. It is only a matter of time. One US dollar will depreciate by 2-40 cents, or even more, and 10000 US dollars will depreciate by 20000-40000 yuan, It's equivalent to your current 67500 yuan. In the future, it will be equivalent to your current 47500-27500 yuan. As long as you invest in RMB, it will be the result. It's not like this if you change it into US dollars. Changing it into US dollars will only make the RMB in your hands appreciate! Now 67500 is converted into 10000 US dollars, and after a period of time, it will be 87500-107500 RMB yuan when it is taken out and then converted into RMB. This is the fact
now there is a better project. It is the first to make money by changing your RMB into US dollars; Second, we should make our robust EA, with an average monthly return of about 5% and a maximum principal risk of 10%. Of course, there are other strategies for EA. We should make it robust according to the risk preference of investors. After all, most investors are risk averse. At present, the operation of robust EA has been nearly 10 months, and the international tripartite financial website has been publicized for more than 3 months. Hundreds of customers are using our robust EA proct. The average monthly income is about 5%, and the maximum principal withdrawal is about 3%, which is very robust
the current stock market is not optimistic, and there is not enough action in the market, even before the bull market. Even if you can get 30% of the annual stock return, the RMB will continue to depreciate, and when you pay out, it will be far less than 30% of the return; I suggest that we can choose to invest in foreign exchange at present. We can find a reliable and qualified foreign exchange platform to deposit our money. Our platform is very good. Capital security, trading environment, back office management system and our service are all great. Even if we don't do our steady EA, we only deposit it in US dollars and withdraw it after a period of time, your RMB will appreciate! Compared with stock speculation, bank financing, various types of RMB financial procts, value preservation and appreciation much more
if RMB is converted into US dollars and deposited in the bank, each person will only have the maximum amount of US $50000 per year, and the payment proceres are quite troublesome.
1. It is necessary to install anti-virus software, update the virus library in time, install firewall (anti Trojan horse, hacker attack, etc.), kill virus regularly, and maintain the security of computer operation
it is recommended that the owner of the building can install Tencent computer manager, which is a free professional security software with two in one anti-virus Management (only need to download one ), small memory, good anti-virus, good protection, and no false alarm and killing. It has a world-class anti-virus software embedded anti-virus engine, such as cloud killing engine, anti-virus engine, Jinshan cloud killing engine, Avira killing engine, xiaohongsan and killing repair engine
software upgrade, vulnerability repair and garbage cleaning are automatically and regularly set, which is necessary for lazy people
2; Open Tencent computer manager toolbox vulnerability repair
3. Don't go to some unknown websites or download things casually
4. You should also be on guard against portable storage devices (such as USB flash disk, where viruses are rampant recently)
5. Don't go to unknown websites or receive strange e-mails. After downloading the compressed package file, scan the virus first
6. Close unnecessary ports
7. If you have time and energy, learn some common computer skills and knowledge
finally, I would like to say that if you are very careful but still poisoned, you can't help it It's a good choice to backup the system with ghost.)
