bitcoin mining machine is one of the ways to obtain bitcoin. Bitcoin is a kind of network virtual currency proced by open source P2P software
it doesn't rely on the issuance of specific monetary institutions, and it is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction

the issue and transaction of bitcoin are realized by mining, and it is cast at a certain but slowing rate. Each new block is accompanied by a certain number of new bitcoin from scratch, which is used as a coinbase transaction to reward the miners who find the block
the reward for each block is not fixed. For every 210000 blocks mined, it takes about four years, and the currency issuance rate is reced by 50%. In the first four years of bitcoin's operation, each block created 50 new bitcoins. Each block creates 12.5 new bitcoins.

2) in the notice issued by the five ministries and commissions, bitcoin is defined as "special commodity", which can be legally held at its own risk
3) at present, there are three risks in bitcoin: cross risk, price risk and "running away" risk.

In the face of serious violations of bitcoin trading platform, supervision should never be soft handed and shut down.
WiFi Internet access may leak Internet access records
1. CCTV programs expose the security risks of free Wi Fi procts.
recently, CCTV's "news studio" column has exposed the case of how the "Internet artifact" under the banner of free Wi Fi, such as Wi Fi master key, divulges the personal privacy of wi fi users
just when she couldn't figure it out, the technician asked Xiaoshang to recall whether she had any friends who had installed such procts and connected to her home's Wi Fi. Then she remembered that when she was helping her aunt cook with Wi Fi, she saw her aunt installed a Wi Fi master key
this means that as long as you have installed procts like Wi Fi master key, it will automatically share your password when you connect to Wi Fi. What's more worrying is that if hackers use such procts to connect users' Wi Fi, they can monitor, attack and intercept users' bank card information at will, which poses a great threat to users' privacy
Not only that, if hackers attack enterprise Wi Fi, it will pose a serious threat to the business privacy of the enterprise, and cause huge economic losses to the enterprise. LBE security expert Fang Zhenyu demonstrated how to use Wi Fi master key and simple tools to enter the enterprise LAN to view enterprise privacy filesalthough procts such as Wi Fi master key have recently modified some infringement settings and functions under the pressure of public opinion, e to long-term accumulation and huge user groups, such applications still have unavoidable security problems
Yes, there is a leak
in the phishing WiFi environment, if a netizen logs in to the microblog, the hacker can easily hijack the netizen's microblog account by using the conversation mechanism existing on the Internet, which can not only browse the netizen's private message content and encrypted photo album as the owner, but also send microblog and delete microblog
and if Internet users purchase online after accessing WiFi, hackers can also directly access their online shopping accounts to view Internet users' purchase records, personal contact information, home address, etc

related precautions:
1. Use WiFi hotspots in public places carefully. WiFi provided by the official organization and with verification mechanism can be used after being confirmed by the staff. Other public WiFi that can be directly connected and do not need verification or password has high risk, which may be behind the phishing trap and should not be used as far as possible
2. When using WiFi hotspots in public places, online shopping and online banking should be avoided as far as possible to avoid the disclosure of important personal sensitive information or even bank transfer by hackers
