Bitcoin test
the price of bitcoin is always floating, so the price of bitcoin for RMB is always changing. From the beginning, a few years ago, when bitcoin was converted into RMB, it was only one to several, and finally it graally developed to one to more than ten, and then to one to dozens. At this time, it has been very shocking, and many people think it is a very strange phenomenon, As a virtual currency, although many people don't know what its main function is, most people think it's a bit similar to stocks, so they made a series of investments in bitcoin. Until January 2020, the value of bitcoin has grown crazily, rising to nearly 1:47000 this growth rate has exceeded most excellent stocks. Many people are shocked and often want to understand why this phenomenon occurs. In fact, my analysis is mainly caused by the following reasons:
3 Of course, one of the main reasons why the price of bitcoin has risen so fast is also related to the psychology of chasing up and killing down. For example, when many stocks have been rising, more people will buy them, but when they are falling, many people withdraw because of fear. So far, bitcoin's rise is still very large, Therefore, some people think it has investment value, so they have been buying it
there are some points for attention in account setting. It is suggested to set a common account in e-mail
then there is the most important miner account setting. Miner obviously refers to CPU or GPU. You need to set an account for each CPU or GPU. Suppose you have two hd7990, you need to set four different accounts for four GPUs
after the account registration, it's time to take the second step. Download the bitcoin miner. Here we recommend the small and easy-to-use guiminer, which can support CPU, oepncl, CUDA and other computing modes. Your CPU and graphics card can achieve maximum performance
guiminer, a bitcoin miner, still needs to make certain settings. After the interface is changed to Chinese, it will be very simple
if the setting is correct, click the "start mining" button, the graphics card will soon enter the full speed running state, the temperature and fan speed will increase, and you can also monitor the state through gpu-z or graphics card driver
the computing power displayed by guiminer is only a theoretical value. To know the actual output of bitcoin, you need to log in to the mine pool website, btcguild, to monitor your account information
now let's assume that you have g up several bitcoins, which naturally exist in btcguild, a foreigner's website. They can't be traded or converted into paper money for the time being
the functions provided by bitcoin China trading platform are clear at a glance, and you can understand them as soon as you read them, so you don't need to introce them any more. After you register, you can study them slowly
click the "bitcoin recharge" function of bitcoin China trading platform, and the system will provide you with a one-time bitcoin digital wallet address. This address can only be recharged once (for security reasons of the platform). After successful recharge, it will be invalid, and then the system will provide you with another address. Remember to update the wallet address in time every time, Otherwise, it will lead to recharge failure or loss
OK, now we import bitcoin from foreign websites into bitcoin China website, and it's up to you to deal with it. Keep it for appreciation, listing and selling, and exchange it for RMB. Specific how to operate, this Chinese website is easy to operate, we slowly study it
finally, let's talk about the equipment used in the bitcoin mining test. At first, I thought it was just an ordinary hd7870, but its computing power was much better than that of the ordinary hd7870. The key is that guiminer recognized it as the Tahiti core, which is the only core of hd7900 series. Looking at gpu-z, the card originally had as many as 1536 stream processors, Generally, the hd7870 of Pitcairn core has only 1280 stream processors. No wonder Dylan's graphics card has super computing power
for friends who hang up for a long time, performance is not the most important, and stability is the most important.

how to use the three technical indicators to understand the rise and fall of bitcoin
6 people agreed with the article
read it for you

recently, "bitcoin broke through $8000" has been on the hot search. For a while, bitcoin rose, reborn rose sharply, and Ethereum led the rise... A week later, this big play dominated by bitcoin didn't seem to come to an end, and the trading volume was once pushed up to 100 billion US dollars
in the investment world, "madness" and "fear" coexist. Today's "madness" stems from last year's long-term "fear". However, this time, coincola Cola Research Institute tracks and analyzes the technical indicators behind the rising market, and deconstructs the "passion" of the market with the "rationality" of data< (1) mining and bitcoin price
start with the relationship between mining and bitcoin. The core technology of bitcoin is "blockchain", which is connected by blocks. Each block corresponds to a bill. All transaction information and transfer records of bitcoin are recorded on the blockchain. Every other point in time, the bitcoin system will generate a random code on the system node. Due to distributed accounting, all computers on the Internet can search for the code. Whoever finds the code will generate a block and then get bitcoin. This process is mining. Calculating this random code requires a lot of GPU operations, so miners need to use mining machines with massive graphics cards to make profits
1. Bitcoin computing power: starting to pick up
remarks: June 2018-may 2019 bitcoin hash value
data source: bitcoin visual, coincola Research Institute
the above figure shows the bitcoin hash value. The hash value of the bitcoin network represents the computing power of the blockchain. The growth of computing power means that miners increase mining investment or increase the number of miners. Since the second half of 2018, the hash value has recovered from falling back to picking up, from 32eh / s at the end of the year to 50eh / s now, and the recent growth trend is remarkable. The continuous growth of bitcoin hash value (representing computing power) indicates that the market is optimistic about the future of bitcoin
2. Mining difficulty: stepped up
remarks: bitcoin difficulty from June 2018 to may 2019
data source: bitcoin visual, coincola Research Institute
the figure above shows bitcoin difficulty. Since 2019, the difficulty of bitcoin mining has increased in a step-by-step manner, from the low 5T to the current 7T. It can be seen that the rapid rise of bitcoin in this round has reced mining costs and increased market entry personnel. The increasing difficulty of mining means that there are profit opportunities in cryptocurrency market, and the market is generally optimistic< (2) the number of active addresses and transactions on the chain are important indicators reflecting the activity of cryptocurrency, which are highly correlated with the price of cryptocurrency
1. The number of active addresses on the bitcoin chain: a straight line rise
remarks: the number of active addresses on the bitcoin chain from June 2018 to may 2019
data source: coinmetrics, coincola Research Institute
active addresses refer to the addresses where transactions have taken place every day, that is, how many independent addresses conct transfer transactions on the chain every day. Since 2019, the number of active addresses on the bitcoin chain has been rising, especially in recent years. From 540.60143k in January to 832.592k now. It shows that the rapid growth of active users of cryptocurrency is a very positive signal for the market
2. The number of transactions on the bitcoin chain: continued to rise
remarks: the number of transactions on the bitcoin chain from June 2018 to may 2019
data source: bitinfo charts, coincola Research Institute
since 2019, the number of transactions on the bitcoin chain has continued to rise, from 235k in early 2019 to 374k now. Moreover, since April and may, after two rounds of sharp rise in the price of bitcoin, the number of transactions on the chain has remained at a high level, even showing signs of a short-term surge< (3) lightning network and bitcoin price
in essence, lightning network adds a layer to the basic layer of bitcoin blockchain in order to make the transaction fast and cheap. With the existence of lightning network, users can remit money to each other at any time and pay very little. Lightning network represents not only the technical level of bitcoin, but also the important basis of bitcoin value
1. Lightning network nodes: rapid growth
remarks: bitcoin lightning network nodes from January 2018 to may 2019
data source: bitinfo charts, coincola Research Institute
the test version of lightning network started on the bitcoin main network on March 15, 2018. The number of lightning network nodes was only 64 at the beginning of 2018 and increased to 2329 at the end of 2018. Since 2019, the number of lightning network nodes has increased rapidly, and now it has reached 4289. In less than half a year, the number of nodes has doubled. The continuous expansion of nodes indicates the continuous upgrading and development of bitcoin lightning network technology, which is an important indicator of bitcoin price
2. Lightning network capacity: speed up
remarks: bitcoin lightning network capacity from January 2018 to may 2019
data source: bitcoin visual, coincola Research Institute
the data above shows that as of May 15, 2019, bitcoin lightning network capacity has increased to 1039 BTC, equivalent to 833usd, while at the beginning of 2019, it is only 504btc, Lightning network capacity doubled, and the growth rate accelerated. This means that the expansion of bitcoin has been well solved in lightning network technology, which will help keep the payment channel active and effectively support the functional application of bitcoin
the performance of mining, chain trading and lightning network is closely related to the price of bitcoin. On the one hand, the rise of bitcoin price acts as a catalyst to stimulate its performance in mining, chain and lightning network; On the other hand, mining, chain trading and lightning network are the important cornerstone of bitcoin price trend and the important basis of bitcoin price expectation<

warm tips:
1. According to the notice and announcement issued by the people's Bank of China and other departments, virtual currency is not issued by monetary authorities, does not have monetary attributes such as legal compensation and compulsion, is not a real currency, does not have the same legal status as currency, and cannot and should not be used as currency in the market, Citizens' investment and transaction of virtual currency are not protected by law
2. Before investing, it is recommended that you first understand the risks existing in the project, and clearly understand the investors, investment institutions, chain activity and other information of the project, rather than blindly investing or mistakenly entering the capital market
3. The above explanation is for reference only. Investors should not use such information to replace their independent judgment or make decisions only based on such information, which does not constitute any investment operation

Mining is burning graphics card, the following methods can identify their own graphics card is mine card
1: through the naked eye to identify whether the hardware is mine card, in fact, through other ways can also be measured, for example, you go to the computer to test the overclocking performance of the mine card, to compare with the official data, to test the stability of the power supply of the mine card, It can also be measured whether it is a mine card or not
2: the first point is to see if there are any dirt and oil stains on the mine card. If not, it proves that the seller may have done better treatment, or it is not the mine card. If the mine card is very dirty, nine times out of ten it is the mine card. Then we have to carry out the next operation, that is to open the mine card
3: we should pay attention to whether there is an invoice with warranty. The warranty can be guaranteed at the warranty points all over the country, which is not a mine card
extended information
how to avoid buying mine cards: try to buy new cards at the official flagship store of Taobao Jingdong, and if you want to buy second-hand graphics cards cheaply, you can't guarantee it
if the budget is really limited and you have to buy second-hand graphics cards, you should also try your best to buy them by yourself. Don't believe that Internet cafes or studios or companies go bankrupt. Most of the cards bought through this channel are mine cards. Of course, if the indivial buyer has a large number of graphics cards in his hand, please be careful. This probability is also mine cards. Finally, I hope you can avoid mine card, buy your favorite graphics card, happy game
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it
bitcoin is a kind of P2P digital currency
bitcoin is not issued by a specific monetary institution. It is generated by a large number of calculations based on a specific algorithm. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions
the biggest difference between bitcoin and other virtual currencies is that the total number of bitcoin is very limited and it has a strong scarcity. 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 21 million
this virtual currency only needs the computing power of the computer, and it has no technical content. Basically, it only needs to hang up to "generate" bitcoin, and bitcoin can be traded at any time, so as to transform it into real currency
if you want to get bitcoin, you need to download the special "mining software" and set it to start
In general, the computing power of GPU is much higher than that of CPU, and even the entry-level graphics card is much better than the top i7 series. So it indirectly tests the performance of the graphics cardMining index is to test how long it takes for a computer graphics card to dig out bitcoin or lettercoin. Because it was popular to dig all kinds of money to earn commission, the corresponding software also added mining index evaluation function, such as Master Lu
Open Master Lu and click the mining index on the right to pop up the middle interface as shown in the figure. Of course, the graphics card does not support it. If the graphics card supports it, click the "one click test" below, and the mining index of the computer will be evaluated after a period of time
February 24 (Xinhua) the security of encrypted digital currency assets is completely based on the security of the private key of encrypted digital wallet, which is the only digital asset certificate. Once the private key is created, it cannot be modified and reset. As long as the private key is not lost, the asset will not be lost. Therefore, the whole security topic of encrypted digital assets is around the storage and use of private key. For the light wallet mode used in mobile terminal wallet, the security of user terminal private key storage is a very core and key problem. If the design is improper, it may lead to the loss of private key and the theft of assets
Jaxx is another well-known mobile cryptocurrency wallet, which has a large number of functions, including supporting multiple currency types, as well as the recently added digital currency exchange platform, allowing users to exchange bitcoin, Ethernet and erc20 tokens in the wallet
when we check the data backup mechanism of Jaxx, we find a major security vulnerability, which is more serious than bitcoin wallet. In fact, the private key stored in Jaxx can be stolen by hackers with little effort
