bitcoin is a kind of electronic currency / network virtual currency
bitcoin: also known as "bitcoin", is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats, equipment, etc. in online games. Internet users can also use bitcoin to buy real goods
on February 26, 2014, Joe Manchin, a Democratic senator from West Virginia, issued an open letter to a number of regulatory authorities of the US federal government, hoping that the relevant authorities would pay attention to the status quo of bitcoin's encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency
from 12:00 noon on January 24, 2017, China's three major bitcoin platforms officially began to collect transaction fees
extended data:
currency features:
1, decentralization: bitcoin is the first distributed virtual currency, the whole network is composed of users, and there is no central bank. Decentralization is the guarantee of bitcoin's security and freedom
2, 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
3, exclusive ownership: private key is needed to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself
4, 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
5, no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay
6, cross platform mining: users can explore the computing power of different hardware on many platforms
advantages of bitcoin:
1, it is completely decentralized, without issuing institutions, it is impossible to manipulate the number of issues. Its distribution and circulation are realized through open-source P2P algorithm
2, anonymity, tax exemption and supervision free
3, 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
4, borderless and 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
5, Shanzhai people are difficult 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 very 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 counterfeit 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
the weakness of bitcoin
1, the fragility 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
2, the transaction confirmation time is long. When bitcoin wallet is first installed, it will consume a lot of time to download historical transaction data blocks. While bitcoin transaction, in order to confirm the accuracy of data, it will take some time to interact with P2P network, and the transaction will be completed only after the whole network is confirmed
3, 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
4, 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 distinguish 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
The user promises to abide by the following rules of bitcoin trading in the process of entering into bitcoin trading and concting bitcoin trading with other users through bitcoin
-
Browse transaction information
when browsing bitcoin transaction information, the user should carefully read all the contents contained in the transaction information, including but not limited to bitcoin price, entrusted volume, handling charge, buying or selling direction. The user can only click the button to trade after fully accepting all the contents contained in the transaction information
-
submit delegation
after browsing the transaction information and confirming that it is correct, users can submit transaction delegation. After the user submits the transaction entrustment, that is, the user authorizes niubit to act as the user's agent for the corresponding transaction matching. Niubit will automatically complete the matching transaction when there is a transaction that meets the user's entrustment price without notifying the user in advance
-
View transaction details
users can view the corresponding transaction records in the transaction details of the management center to confirm their detailed transaction records
-
revoke / modify a delegation
before a transaction is concluded, the user has the right to revoke or modify the delegation at any time
Introction 1
interesting step is a community of mining machines and exchanges for blockchain assets. After we download the app and complete the real name certification, as long as you walk 4000 steps a day, you can get 0.3333 candies, and the value has been rising. You can get 15 candies in 45 days. You can withdraw 5 candies in the first month, and you can use a primary scroll to buy goods in the second month, In fact, it is equivalent to that we do nothing and get money on this platform every day
Introction 2
why is candy valuable? First of all, everyone can use the app to dig for candy revenue, which is very attractive. It will attract a large number of users to participate. Then the number of APP users will be very large, and some people will be willing to invest in this platform, because the total amount of candy is constant. The more people come in, the more demand, the less candy, and the higher the value of candy, Investors are willing to buy candy and wait for appreciation. Therefore, it is not the platform that is burning money for charity, but the investors in the market who are investing to buy candy in our hands are giving cash to users, which is the source of candy value
Introction 3
the app is now in the drainage period. After the number of users is established, the app can do a lot of things, such as social networking, e-commerce, short video, and so on, and it can realize more value. Then, the currency in circulation is naturally these candies, so the appreciation of candies is certain, and candies represent the value of the platform, Holding candy is equivalent to holding shares in this platform, so many people will invest in buying candy in other people's hands
Introction 4
advantages of fun step
first, the entrance is large, everyone can get candy for free, which is a huge entrance
secondly, it is sticky and can get candy every day, which leads to users logging in every day
thirdly, with zero investment, neither the recommender nor the recommender is under pressure. They just introce others a software that makes money every day
introction 5
how to earn more candy? The more people you share, the more active you will be. The candy you get will multiply every day, and you will also get a bonus. There are people trading candy all the time on the platform, and the platform will charge transaction fees, which is a huge profit. The platform will distribute the income of transaction fees to users with high activity in proportion. When the number of users you recommend reaches about 70-80, The team keeps splitting. If you reach the level of 1 star, you can get nearly 10000 monthly dividends. If your team keeps splitting, your daily income will increase automatically. Upgrade 2 stars and 3 stars to form an automatic wave of income
Introction 6
this is a very good opportunity. I hope everyone can move to reach the one star level quickly. At present, according to the development speed of the market, it generally takes about 15-30 days to reach the one star level. Refuelling partners.
there are many factors driving up the price of bitcoin. In fact, in addition to bitcoin, the prices of other similar digital currencies are soaring. Bitcoin is generated based on algorithms, and other digital currencies with similar principles include lightcoin, Ethereum, dogcoin, etc
the price of these digital currencies, especially Ethereum, has also increased significantly recently. Ethereum and other coins are still profitable even if they use graphics cards for mining. Recently, amd graphics cards are out of stock, and the culprit is Ethereum and other coins. For this reason, AMD and NV intend to launch mining special supply cards to avoid mining affecting the normal sales of graphics cards
The definition of digital economy is a series of economic activities with digital knowledge and information as key proction factors, modern information network as an important carrier, and the effectiveness of information and communication technology as an important driving force for efficiency improvement and economic structure optimization. Generally speaking, digital economy is a new economic form with the information technology revolutionwe often call the era of instrialization the era of atoms and the era of information the era of bits. Why do we say that? As we all know, atoms make up molecules and molecules make up matter. Therefore, we also call the era of instrialization the era of matter
then why do we call the information age the bit age? Here, it is necessary for us to explain what bit is: bit is the smallest counting unit in a computer; When we input any letter of English into the computer, the letter takes up a byte, which is composed of bits. Chinese characters are more complex. When we input a Chinese character to the computer, it takes up two bytes. Therefore, we don't care to call it the era of bit, sometimes it is also called the era of digital survival
The formula of long-term marginal cost is expressed as:
LMC = △ LTC / △ Q
or: LMC = DLTC / DQ
Mr = AP = P, which is the characteristic of perfect competition market, that is, the demand curve P (q) of perfect competition market coincides with marginal cost curve MR and average cost curve AP. Mr = LMC = SMC = lac = sac, which is the condition of perfect competitive market equilibrium
LMC, SMC, lac and sac were long-term marginal cost, short-term marginal cost, long-term average cost and short-term average cost respectively
Because lac is the envelope of sac, return to scale changes and remains unchanged in the long run. If the return to scale remains unchanged, lac = LMC, which is the lac straight line and the lowest point of sac Increasing or decreasing returns to scale: the lowest point of the intersection of LMC and lac with lac, which is the lowest point of SA corresponding to proction
extended data:
(1) each STC and LTC has only one common point. This is because for each STC, there is only one point tangent to the line from the origin. Or, it can be said that for each sac, there is only one point intersecting with SMC, and at this point sac drops to the lowest point
(2) STC can only be located above LTC, that is, except for common point, all other points on each STC are larger than LTC under the same proction state. Otherwise, if the STC falls below the LTC, it means that the short-term average cost sac is less than the long-term average cost lac, which is contradictory to the fact that lac is the lowest point of sac
(3) STC is tangent to LTC only when lac reaches the lowest point. This is because at every point on the LTC, it is the common point with an STC. At these common points, the corresponding STC is tangent to a straight line from the origin respectively,
however, for LTC, it is tangent to a straight line from the origin only when the lac drops to the lowest point. Therefore, except for the point on the LTC corresponding to the lowest lac, LTC and STC all intersect, and there is only one intersection
