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
2. How to dig bitcoin with a card
3.
Amd graphics card is recommended for bitcoin, n card is not suitable
moreover, one video card can't dig one coin a week, so it needs several amd video cards to dig together, and some even use mining machines. At present, mining on the computer platform is unprofitable for ordinary users unless they are professional players
4. This is legal in some countries, and the domestic attitude is not very clear. Anyway, it is not illegal
5. There is an upper limit for bitcoin, which is controlled by a few people. Now there are too many people to dig, making it more difficult to dig. Digging for half a year may not be able to get back to the original. In the end, I worked for foreigners for nothing.
6. Mining only depends on the floating-point computing power of the graphics card, and nothing else, so it depends on the specific model of your graphics card
R9 280x / HD 7970 can dig two in three months on average
don't think about it. The worst way to mine is to use a graphics card above hd7850. Your hd7660d core display can't find one in a year.
R9 280x / HD 7970 can dig two in three months on average
don't think about it. The worst way to mine is to use a graphics card above hd7850. Your hd7660d core display can't find one in a year.
7. At present, rx570 4G, rx580 8g, gtx1060 3G, gtx1060 6G and other graphics cards are the most popular ones for mining. High end graphics cards can also be used for mining, but the cost is relatively high,

9. It adopts the strong double factor authentication mode of one time one secret, which solves the security and reliability of identity authentication. The identity authentication method based on USB key is a convenient, safe and reliable identity authentication technology developed in recent years. It also provides USB interface, which is common with today's computers. USB key is a small hardware device with USB interface, The USB flash disk is no different from our common USB flash disk, but its internal structure is not simple. It has a built-in CPU, memory and chip operating system (COS), which can store the user's key or digital certificate, and use the password algorithm built in the USB key to realize the user's identity authentication.
every USB key has hardware pin code protection, The pin code and hardware constitute two essential factors for users to use the USB key. Users can log in to the system only when they obtain the USB key and the user's pin code at the same time. Even if the user's pin code is leaked, as long as the USB key held by the user is not stolen, the legal user's identity will not be counterfeited; If the user's USB key is lost, because the finder does not know the user's pin code, and can't impersonate the legal user's identity,
the USB key has a secure data storage space, which can store secret data such as digital certificate and key. The reading and writing operation of the storage space must be realized through the process, and the user can't read it directly, in which the user key can't be exported, To prevent the possibility of ing user's digital certificate or identity information,
USB key has built-in CPU, which can realize various algorithms of encryption, decryption and signature. Encryption and decryption operations are carried out in the USB key to ensure that the key will not appear in the computer memory, so as to prevent the possibility of user's key being intercepted by hackers, The two application modes of USB key are as follows:
first, based on the impact response authentication mode,
USB key has built-in one-way hash algorithm (MD5), which stores a key to prove the user's identity in the USB key and the server in advance. When the user's identity needs to be verified on the network, First, the client sends a verification request to the server. After receiving the request, the server generates a random number and sends it back to the USB key inserted on the client PC. this is called "impact". The USB key uses the random number to perform MD5 operation with the key stored in the USB key to get an operation result, which is sent to the server as authentication evidence. This is called "response". At the same time, the client sends the result to the server as authentication evidence, The server uses the random number to perform MD5 operation with the client key stored in the server database. If the result of the operation of the server is the same as the result of the response sent back by the client, the client is considered to be a legitimate user.
in the figure, "x" represents the random number provided by the server, "key" represents the key, "Y" represents the result of the random number and key after MD5 operation, Only the random number "X" and the operation result "Y" are transmitted through the network. The user key "key" is neither transmitted on the network nor appears in the memory of the client computer. Neither hackers on the network nor Trojan horse programs on the client computer can get the user's key. Because the random number "X" and the operation result "Y" used in each authentication process are different, Even if the authentication data is intercepted by hackers in the process of network transmission, the key can not be obtained by reverse dection, so the user identity can not be counterfeited fundamentally. I think the answer is OK, but if you write USBKEY code. You should look at embedded development books. Have you ever done MVC code?
