Have QQ bought bitcoin before
Decentralization: bitcoin is the first distributed virtual currency, and the whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom
Global Circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
exclusive ownership: the private key is required to manipulate bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself
low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution
no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome quota and proceres. If you know the other party's bitcoin address, you can pay
cross platform Mining: users can explore the computing power of different hardware on many platforms
advantages
complete decentralization, without issuing institutions, it is impossible to manipulate the number of issues. Its distribution and circulation are realized through open source P2P algorithm
anonymity, tax exemption and supervision free
robustness. Bitcoin is completely dependent on P2P network and has no distribution center, so it cannot be shut down externally. Bitcoin price may fluctuate and collapse, and many governments may declare it illegal, but bitcoin and its huge P2P network will not disappear
no borders, cross-border. Cross border remittance will go through layers of exchange control agencies, and the transaction records will be recorded by many parties. But if you trade with bitcoin, enter the digital address directly, click the mouse and wait for the P2P network to confirm the transaction, a lot of money will pass. It does not go through any regulatory agencies and will not leave any cross-border transaction records
it is difficult for the cat to survive. Because bitcoin algorithm is completely open source, anyone can download the source code, modify some parameters, recompile, and create a new P2P currency. But these counterfeit currencies are fragile and vulnerable to 51% attacks. Any indivial or organization, as long as it controls 51% of the computing power of a P2P currency network, can manipulate transactions and currency value at will, which will be a devastating blow to P2P currency. Many Shanzhai coins die in this link. The bitcoin network is robust enough. If you want to control 51% of the computing power of the bitcoin network, the number of CPUs / GPUs required will be astronomical
disadvantages
vulnerability of trading platform. The bitcoin network is robust, but the bitcoin trading platform is fragile. Trading platform is usually a website, which will be attacked by hackers or shut down by competent authorities
transaction confirmation takes a long time. When bitcoin wallet is first installed, it will consume a lot of time to download historical transaction data blocks. In order to confirm the accuracy of data, bitcoin transaction will take some time to interact with P2P network, and the transaction will be completed only after the whole network is confirmed
the price fluctuates greatly. Due to the intervention of a large number of speculators, the price of bitcoin for cash fluctuates like a roller coaster. Making bitcoin more suitable for speculation rather than anonymous trading
the public did not understand the principle, and the traditional financial practitioners resisted. Active netizens understand the principle of P2P network and know that bitcoin has no legal person to manipulate and control. But the public doesn't understand, and many people can't even tell the difference between bitcoin and q-coin“ "No issuer" is the advantage of bitcoin, but in the view of traditional financial practitioners, "no issuer" currency is worthless

Shared travel refers to a new mode of transportation in which people do not need to own the ownership of the vehicle, share the vehicle with other people in the way of sharing and carpooling, and pay the corresponding toll according to their own travel requirements
including a large number of innovative models represented by taxi software and bike sharing. On the one hand, the mode of shared travel meets the self driving demand of consumers
on the other hand, it avoids the waste caused by the inefficient use of idle vehicle resources, which shows that shared travel has graally become the public's travel choice

extended data
with the rapid spread of bike sharing in major cities across the country, the concept of "sharing economy" is rapidly popularized, and car sharing has also quietly entered people's vision
these car sharing platforms are also like the development mode of bike sharing. They are first distributed in Beijing, Shanghai, Guangzhou and other large cities. Although the number of vehicles and outlets put on each platform is small, they have caused certain repercussions in the market
However, the birth of new things still needs to adapt to the actual social situationon June 1, 2017, the Ministry of transport, together with the Ministry of housing and urban rural development, formulated the guidance on promoting the healthy development of the car rental instry (Exposure Draft) (hereinafter referred to as the exposure draft) to solicit public opinions for a period of two weeks
the draft clearly states that it encourages the development of time-sharing rental cars, and puts forward corresponding regulatory requirements and incentive policies for operating enterprises and users. Compared with the pace of the previous regulatory policies on online car hailing and bike sharing, the regulatory authorities responded more quickly to car sharing this time. The policy is coming, and the instry is developing towards a more standardized direction
However, e to the high operating costs and the difficulty of making profits, the capital boom in the field of shared automobile has not yet arrived. Under the background of the initial policy, whether sharing car can successfully attract capital inflow or still face the dilemma of "cooking without rice"< br />2020 is the 40th year since the establishment of Shenzhen Special Economic Zone.
