How about rx570 graphics card mining
The graphics card market in 2017 is the most special in recent years. In the past few years, no graphics card will increase its price by 100% a few months after its release. RX 580 has achieved this goal. Together with all the graphics cards below 3000 yuan, it has broken through the premium point in an irresistible manner. All this happened with the bitcoin price breaking through 3000 US dollars. After miners swept the RMB 2000 RX 580, the price of low-end RX 560 and even GTX 1050 Ti increased to varying degrees. However, is the price directly proportional to the ability of hash algorithm? Recently, we did a test to collect the new generation of graphics cards at various prices on the market, test the mining speed of Ethernet and bitcoin, and see which card has the highest cost performance
Different from the thousand yuan market, this wave of mining tide has a great impact on high-end graphics cards. In the test results, RX 580 and Rx 480 have almost reached the bottom of GTX 1070. Moreover, the price of Rx 580 is even competing with that of GTX 1070, so the miners directly swept the 3000 yuan market when GTX 1060 3gb / 6GB is out of stock, and GTX 1070 is basically out of stock. The more advanced GTX 1080 is also out of stock, but it's not clear whether the players are forced to go directly to the high-end card or the miners extend their claws to this market. The situation of GTX 1080 ti is only slightly improved, but it's not much better. However, not everyone can afford the 6000 yuan graphics card. Only the top players will be affected, but it's just a narrower choice. It's not the case that the rich can't buy itsummary:
to mine, the first choice is the graphics card with more than 3gb video memory, which is the basis. In addition, the core frequency will affect the mining speed. We have two GTX 1080 cards on hand, one is public version, and the other is MSI GTX 1080 gaming X. the operating frequencies of the two cards are 1885mhz and 1936mhz respectively. After testing, because of the frequency, the latter will be about 4% faster than the former in actual mining. The advantages of high-frequency graphics card are highlighted
So Xiaobian's opinions and suggestions are as follows:the low-end card and the old architecture card are not suitable for mining. GTX 1080 ti is an extreme, with the most powerful performance, but the price is not suitable for large-scale procurement. The mining speed of a card with the same location is much faster than that of N card, The cost performance of GTX 1060 3gb is higher than that of GTX 1060 6GB. The frequency and the number of stream processors / CUDA have a great influence on the performance of the card. The size of video memory has no influence on the mining. It's enough. Different video cards will have different profits if they dig different coins. If you want to further explore, you need to test several currencies, Limited to space, we only select two representative currencies to test
as long as the mine disaster does not occur, the shortage will last for a long time. However, if there is a mine disaster, a large number of second-hand mine cards will directly enter the market. These cards are always running at full load and full speed, and their service life is greatly shortened compared with that of ordinary users. Even if the price is lower, they will roll over at any time, There is no need to start at all. Moreover, the second-hand market will be directly disrupted. At that time, it will be difficult for some normal users to get out of the second-hand market, and the deep-water fish's Dragon killing knife will explode the galaxy. Now it is said that NVIDIA is making some graphics cards without display output interface, which are provided to miners as mine cards. With a certain capacity, if the mine card still can't satisfy the miners, won't the miners buy the graphics card in the consumer market? The only function of these special mine cards is to prevent mine cards from flowing into the second-hand market, which can not alleviate the current shortage of graphics cards

features
we can compare the development of blockchain with the development of the Internet itself. In the future, something called finance Internet will be formed on the Internet. This thing is based on blockchain, and its precursor is bitcoin, that is, traditional finance starts from private chain and instry chain (LAN), Bitcoin series start from the public chain (WAN), all express the same concept - digital asset, and finally converge to an intermediate equilibrium point
the evolution mode of blockchain is as follows:
blockchain 1.0 - digital currency
blockchain 2.0 - digital assets and smart contracts
blockchain 3.0 - Dao, DAC (blockchain self-consistent organization, blockchain self-consistent company) - & gt; Blockchain Society (Science, medical, ecation, etc., blockchain + AI). At present, classified editing blockchain is divided into three categories, among which hybrid blockchain and private blockchain can be regarded as generalized private chain:
public blockchain
public blockchain means that any indivial or group in the world can send transactions, and transactions can be effectively confirmed by the blockchain, and anyone can participate in its consensus process. Public blockchain is the earliest blockchain, and it is also the most widely used blockchain at present. The virtual digital currencies of bitcoin series are all based on public blockchain, and there is only one corresponding blockchain in the world
consortium blockchains
instry blockchains: multiple preselected nodes are designated as bookkeepers within a certain group, and the generation of each block is jointly determined by all preselected nodes (preselected nodes participate in the consensus process). Other access nodes can participate in transactions, but not the bookkeeping process (essentially, trusteeship bookkeeping), It just becomes distributed accounting, the number of preselected nodes, how to determine the bookkeeper of each block to become the main risk point of the blockchain), and anyone else
The performance of rx5708g is equivalent to that of gtx1060 3G, while the performance of rx5704g is slightly ahead of the previous generation rx470d and gtx1050ti
amd radon RX 570 is an accessory proct with high cost performance. Made by AMD, with excellent manufacturing process, guaranteed quality and service life, after-sales guarantee and reasonable price, it is a choice with high cost performance
the performance improvement of rx570 Series graphics card is not too big compared with the previous generation of rx480 and rx470 graphics card, which is about 5-10%. Among them, the performance of rx570 graphics card is slightly better than gtx1060 graphics card. It can be said that the 500 Series graphics card is not like the sharp dragon processor, which can bring tremendous changes to the market
it is more a behavior to adapt to the market. By increasing the core frequency and memory frequency, the rx570 graphics card can be compared with gtx1060 to further strengthen the competitiveness of AMD Series graphics card in the market
in addition, CB lab has also tested the power consumption of the new card. Xiaobian has selected the game of battlefield 1 to test the power consumption performance of the whole machine. It can be seen that the power consumption of rx570 Series graphics card is slightly higher than that of the previous generation, which does not fundamentally solve the problem of high power consumption of a card

backup wallet.dat file
Second, you only need to the wallet.dat file to other hard disk partition, mobile hard disk or U disk to complete the backup
notes for backing up bitcoin Wallet:
back up your entire wallet
in order to protect privacy, bitcoin wallet contains many private keys for receiving transaction change. If you only back up the private keys of visible bitcoin addresses, most of the funds may not be restored from the backup
encrypt online backup
any online backup is easy to be stolen, and even a computer connected to the network is vulnerable to malware. Therefore, it is a good security habit to encrypt any backup exposed to the network
using multiple safe storage places
a single failure is not concive to security. If your backup is not limited to only one place, it is less likely that bad things will lead to irrecoverable wallet. You can also consider using different storage media, such as USB flash disk, paper and CD-ROM
regular backup
the wallet needs to be backed up regularly to ensure that all the latest bitcoin change addresses and newly created bitcoin addresses are included in the backup. However, soon all applications will use wallets that only need to be backed up once
bitcoin wallet encryption tutorial
if you use bitcoin on a public computer, or you think your computer may not be secure enough, you can choose to encrypt your wallet after each use. In addition, your backup wallet file also needs to be encrypted according to this method
first, you need to close the bitcoin client and find the file wallet.dat as described in the three sections of backup wallet. Then, right-click on the file and select Add to compressed file. The following dialog box will appear:
set a file name, check "delete source file after compression", and then click "advanced" tab:
click "set password", enter the same password twice in the pop-up dialog box, click "OK" button, and then click "OK" button, Encryption is done. You will see that the original wallet.dat file in the wallet folder is gone, and there is an additional. Rar file, even if the encryption is successful
you can encrypt the backup of your bitcoin wallet in the same way
precautions for encrypting bitcoin Wallet:
never forget your password
make sure you never forget your password, otherwise you will lose your funds forever. Unlike bank accounts, bitcoin has no password recovery option. In fact, you should be able to remember it even if you don't use it for years. If in doubt, you may need a paper with your password on it and keep it in a place as safe as a safe
use a strong password
any password that only contains letters or recognizable words will be considered as a weak password and can be easily cracked. A strong password must contain letters, numbers, punctuation, and be at least 16 characters long. But that shouldn't prevent you from remembering your password
bitcoin wallet recovery tutorial
bitcoin wallet recovery steps are very simple. Open the WinXP start menu, select "run" and input the following contents:
Explorer% appdata% bitcoin
(Windows Vista or windows 7, directly input it in the "search programs and files" box of the start menu)
for example, my computer path:
C: (some files are hidden, You need to check the tool - Folder Options - View - display all the folders, and then click OK in the app to open the wallet folder of bitcoin official client. After that, your backup wallet.dat file to this folder, and then overlay the original file
if your backup uses WinRAR encryption, you need to enter the correct password first to recover the wallet.dat
the above is the backup, recovery and encryption course of bitcoin wallet.
