3. Ha ha, what do you do, brother? It is estimated that we are peers. Avalon's chip is hard to find. At that time, I was crazy to find it. There is a company in Shenzhen that specializes in Avalon. Its name is Shenzhen Avalon Electronics Co., Ltd. in Huaqiangbei. Their QQ is 1816404459.. However, this company only does wholesale, and has to order 1000 units
coding is very hard, remember to add points^_^

4. The selection of mining machines depends on the computing power, the power consumption and the historical reputation, including the stability and after-sales service of the machines
computing power is the ability of a machine to perform operations, that is, how many hash operations can this machine perform per second. At present, the computing power of the mainstream bitcoin miner is 14T, that is, hash collisions of the 13th power of 14 times 10 per second
power consumption is an indicator of the power consumption of the miner ring operation. Electricity consumption will have a huge relationship with mining costs. Generally, a miner will operate 24 hours a day to excavate, so the power consumption sometimes seems to have a small difference, but in fact, the cost gap is relatively large
here is another little knowledge, that is, digital assets of the same algorithm can be mined by the same miner. For example, bitcoin miner can also dig bitcash, Ethereum miner can also dig Ethereum classic
for more professional knowledge, it is recommended to consult the honeycomb miner. There are professionals to help you select and answer for you. The boss comes from the fire coin, and I feel reliable after personal experience.

5. The main reason is that our country has strict control over foreign exchange
there is another way to solve the problem of not recharging the PayPal account to the US dollar. It is through finding a person to exchange PayPal dollars (using RMB in a certain proportion of exchange), the other party pays the US dollar through your PayPal account to your PayPal account, and you send the remittance through Alipay or domestic bank to the right side, so as to solve the problem of recharging the PayPal account to the US dollar. At present, only local banks in the United States can recharge the PayPal account in US dollars (for example, the Bank of America account you applied for in Shanghai can't be recharged in PayPal), and the PayPal account can't be recharged in RMB.
friendly reminder: you need to find a reliable payer in this way. At present, PayPal certification supports a variety of international credit cards. Certification is very simple. It is recommended that you apply for an international credit card of China Merchants Bank, and you can pay directly through the credit card when shopping.
the work of PayPal consultants is not only to guide customers to register, but also to maintain their accounts in the later stage, for example, customers can't receive the money they call you, If you can't withdraw cash from your bank account or some people have problems with limited accounts, you can ask PayPal customers to help you solve them. Even PayPal consultants will teach you some tips on how to use PayPal, how to use PayPal to save handling charges, and risk control knowledge. If you use it for the first time, do you need a consultant?

When the Internet was just born, the amount of data on the whole network was small, so the simple and convenient transmission mode of HTTP protocol is very easy to use. However, with the development of the Internet, the amount of data on the network is increasing, and the disadvantages of HTTP protocol are graally revealed

about its concept :

1 the dependence on the server storing data is too strong

if there is a problem with the server, the data may be lost. I believe many people have experienced the phenomenon of 404 pages lost when opening a web page, which may be caused by the failure of the data server

When the amount of data required by users is too large, the burden of server transmission will be very heavy, which directly affects the transmission efficiency. If the data users need is compared to water flow, then the bandwidth is the ditch and the server is the reservoir. In a certain period of time, the flow from the reservoir to the ditch is also fixed, and the greater the demand of users, the more time cost will be spent

3 at present, the Internet is very dependent on the backbone network

at present, a large number of Internet data are transmitted through the backbone network, once adverse factors occur, leading to the damage of the backbone network, it will inevitably affect the data access of users

about the second question:

enter the landmark SEG square of Huaqiangbei, and the floor is in the guide. On the 3rd to 5th floors, some merchants have put out various types of poster advertisements, and the shops are basically occupied by the merchants

it is reported that after the mining machinery business started, the seller also had some new practices, and some merchants found a new way to provide derivative services to attract customers

for example, in the custody business, businesses find stable power and sites, and buyers choose custody after purchasing mining machines, and there is no need to consider other issues after paying the custody fee. In a shop with a signboard of "ASUS computer", the Sales Department tried to promote this model, and used a calculator to input various numbers skillfully to demonstrate back to this cycle

notes: about the above questions, I will provide you with my own personal views, and I will also send you a little skill Internet search results - IPFs learning for you
