1. The proction of virtual currency needs a professional team, but if you make a direct currency, there is no wallet, there is no maintenance, and it's just a pure number, it's much simpler, the cost is very low, and a trading platform is thousands of yuan. However, there are serious loopholes in this platform and it is easy to be attacked
if you want to create a virtual currency like bitcoin, Ruitai coin and Qianjin card, you need to make some efforts. First of all, these coins need card method and a downloadable wallet. The application scenarios of this kind of currency have been determined. At the same time, you need to create a secure and reliable trading platform.

2. At present, bitcoin is the only reliable virtual currency. Bitcoin is a kind of virtual currency generated by the corresponding algorithm, which needs to use a large number of mining machines, that is, servers for mining. At present, only the virtual currency issued by the central bank is legal in our country, and the others are illegal
I hope I can help you. Thank you for your adoption.

3. Building a mine pool is not so simple, enough servers, enough computing power
4. Software and hardware come second... If you can't afford the electricity charge, you don't recommend yourself to mine by computer.
with the current market price and quantity of mining, those who don't go into the mining pool are g by yourself in places with subsidized electricity charge, such as hydropower stations and agricultural pumping stations. Civil electric mining is at a loss

5. HTP was up more than 30 times before. Longchi issued a power currency, called HRT. I don't know if it can rise at that time. HRT will be on the coinsuper exchange in December. Coinsuper is one of the initiators. At the same time, cen with coinsuper platform currency can also lead the airdrop of HRT, so you can pay attention to it at that time.
6. 1. First of all, as a qualified miner, we must prepare a professional mining tool
2. The mining requirement is level 11, but I suggest that we go to level 20 before mining. There are two reasons
the No. 11 backpack of level 1 has less load, especially the mage has already loaded the load before digging a few mines. It's very troublesome to go back and sell it and run back and forth
the second trumpet is easy to be killed. In order to carry more ore at one time, the package is basically empty. Once more than three people kill you, you will die before you have time to press back to the city.

7. China has completely stopped trading. Thank you
8. Any computer can operate, just a professional miner, a day may top your computer work for a month or even longer
9. After going to the high epidemic area, when you come back, you need to report to the community where you live for nucleic acid screening and automatic isolation for 14 days. And report the isolation to the community.
10. 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?
