How many graphics cards can you dig in a day
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
21.5 * 3600 seconds * 24 hours = 1857600 M / day
1857600 / 1024 / 1024 = 1.7715 T / day
a t of computing power / day can dig bitcoin worth 4.03 yuan
1.7715 * 4.03 = 7.14 yuan / day
since 2017, bitcoin has reached new heights. Yesterday (May 23), the value of bitcoin broke through the ￥ 16000 mark, hyping virtual currency, becoming a matter that the general public can participate in, And a little bit of technical level, both fried money, but also began to have the technical content of mining
as we all know, virtual currency has a numerical peak, the more difficult it is to dig. In fact, it's hard to judge whether to lose money or not if we continue to dig. Therefore, in the end how to dig, dig what can be the fastest back to this, this paper studies the above two core issues based on the current market situation
First of all, which brand is 580
Second, the difference between N card and a card is also different
n card not only supports OpenCL mode, but also CUDA mode mining device is available. In CUDA mode, the performance of gtx580 is 30% higher than that of OpenCL mode. In CUDA mode, not only the performance is improved, but also the power consumption ring mining is reced, from 366 watts to 329 watts. This shows that the algorithm efficiency of CUDA mining is better than that of OpenCL mining, but e to the limitation of its own computing power, it is not as good as a card with massive stream processor
how much can be mined is to be tested
You can't dig in a day. It takes 2000 years
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
in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. Many professional mines at home and abroad are operated 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 in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned
extended data:
bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system
bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer
when bitcoin was born in 2009, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25
when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million
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
BVI company cooperates with Singapore foundation for al structure information confidentiality
how to legally operate the ICO issue has always been the focus of attention of people in the instry
today we will talk about the concept of al structure of BVI company and Singapore foundation. In fact, the al structure is not new to many people, But in fact, many people may not be familiar with the project development applied to the ICO field.
first of all, let me talk about BVI company in the al structure
Introction to BVI company
as we all know, BVI is one of the overseas offshore investment centers with the fastest development of 9370 and 6165 in the world, and the company registered here is called BVI company, It is commonly used in the vie trading framework for listing overseas or in Hong Kong. According to the law of the island, all companies incorporated in the island are exempt from tax except for the statutory annual registration fee (very small). Many well-known international companies set up tax avoidance companies in the island for their tax avoidance operations, and carry out complex international tax avoidance business activities. The information is confidential. It is one of the preferred architectures for the majority of investors.
{rrrrrrr}
the basic way to build the compliance architecture is as follows:
1. Register BVI, as the issuing entity, keep personal identity information confidential, and completely avoid taxes.
2. Set up the Singapore Foundation (CLG), as the project operator, to legally operate blockchain projects and digital currency operations
3. Only the promotion and technical teams are reserved in China, which are clean and compliant with the operation and distribution
legal compliance of compliance framework:
1 legal opinion: (white paper compliance + token uncertified certificate)
legal opinion issued by lawyers to determine whether the tokens issued by the project comply with the relevant laws and regulations of the monetary authority of Singapore (MAS), especially the white paper project with al currency, needs to be strictly reviewed by lawyers
2 government compliance endorsement: issue official endorsement to further enhance project compliance (provided that a legal opinion has been issued)
3 Singapore sto compliance: assets with certificate attributes To facilitate compliance and issuance under the current sto management guidelines in Singapore, the following proceres are needed:
1 to register BVI company
2 to register Singapore foundation
3 to issue Singapore legal opinion
4 to issue ICO
the project party registers a limited liability company in BVI and claims that the main body of the foundation is BVI company. Then we set up a public welfare foundation (CLG) in Singapore. BVI company cooperates, authorizes and operates ICO related projects. Of course, each currency needs an independent foundation to operate, so as to avoid the risk of currency trading on the foundation body. Finally, Singapore commonweal foundation authorized domestic marketing team and technology R & D team to carry out project promotion and technology R & D
now the fastest home CPU is not as fast as a thousand yuan graphics card.
the efficiency is too low
