They are:

bitcoin

the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, the open source software was designed and released, and the P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

bitcoin cash

bitcoin cash is a new version of bitcoin with different configurations launched by a small number of bitcoin developers

virtual currency refers to non real currency. Well known virtual currency, such as network company's network currency, Tencent company's Q currency, Q point, Shanda company's voucher, Sina's Micro currency (used for micro games, Sina reading, etc.), chivalrous Yuanbao (used for chivalrous road game), silver pattern (used for bixue Qingtian game)

the popular digital currencies in 2013 are bitcoin, Leyte coin, infinite coin, quark coin, zeta coin, BBQ coin, pennies (Internet), invisible gold bar, red coin and prime currency. At present, hundreds of digital currencies are issued all over the world. Popular in the circle & quot; The legend of "bitcoin, Wright silver, infinite copper, pennies aluminum"

Litecoin (LTC, currency symbol: 321;) It is based on & quot; Point to point & quot It is also an open source software project under MIT / X11 license. It can help users make instant payments to anyone in the world

lightcoin is inspired by bitcoin (BTC) and has the same implementation principle in technology. The creation and transfer of lightcoin is based on an open source encryption protocol and is not managed by any central organization. Lightcoin aims to improve bitcoin. Compared with bitcoin, lightcoin has three significant differences. First, the lightcoin network can process a block every 2.5 minutes (instead of 10 minutes), so it can provide faster transaction confirmation. Second, the lightcoin network is expected to proce 84 million lightcoins, four times the amount of money issued by bitcoin network. Thirdly, the scrypt encryption algorithm first proposed by Colin Percival is used in lightcoin's workload proof algorithm, which makes it easier to mine lightcoin on ordinary computer than bitcoin. Each Leyte is divided into 100000000 smaller units, defined by eight decimal places

extended materials:

it is based on bitcoin protocol, but different from bitcoin, it can be & quot; efficiently implemented by consumer hardware; Mining & quot;. Liteoin provides you with faster transaction confirmation (2.5 minutes on average). It uses hard memory and mining workload proof algorithm based on scrypt (an encryption algorithm). It is oriented to ordinary computer and graphics processor (GPU) used by most people. The litecain network is expected to proce 84 million currency units

one of the design purposes of litecoin is to provide a mining algorithm, which can be run simultaneously on the bitcoin mining machine. With the rise of application specific integrated circuits (ASIC) designed for bitcoin mining, litecoin is also closely following the technological evolution. But before the widespread use of litecoin currency, it is unlikely that there will be an application specific integrated circuit (ASIC) specially designed for litecoin[ 1]

a peer-to-peer network, similar to bitcoin, processes transaction, balance and issue of lightcoin through script workload proof scheme (when a sufficiently small hash value is found, a block will be created and lightcoin will be issued, and the process of discovering the hash value and creating the block is called & quot; Mining & quot;). The issuing rate of Leyte coins is reced by half every four years (every 840000 pieces) according to the proportional sequence, and finally the total number of LTCs is 84 million. Unlike bitcoin, the memory intensive feature of script makes it more suitable to use graphics processor (GPU) for & quot; Mining & quot;. FPGA (field programmable gate array) and ASIC (application specific integrated circuit) implemented for script are more expensive than sha256 used for bitcoin

currently, lightcoin can exchange legal tender and bitcoin, most of which are through online trading platforms. Revocable transactions (such as credit card transactions) are generally not used to purchase Leyte, because Leyte transactions are irreversible, which brings the risk of refund. As of April 25, 2013, a Leyte is worth about $3.97 or 0.028 bitcoin. This makes Leyte the second largest electronic currency with a market value of about $35 million

bitcoin is an e-money payment system based on the global network
bitcoin is an e-money system based on the global decentralized network system, without the participation of central banks and third-party institutions, with a fixed total amount. Bitcoin has the characteristics of payment system and currency at the same time. Global network nodes are maintaining the bitcoin network all day<

English: bitcoin currency symbol: abbreviation: BTC or XBT

Introction to bitcoin by wiki
different from traditional currency, bitcoin's operation mechanism does not rely on the support or credit guarantee of central bank, government and enterprise, but on the network agreement reached with seed files in the network, which is a decentralized and self-improvement monetary system, Theoretically, it ensures that no one, institution or government can control the total amount of bitcoin or create inflation. Its total amount of money graally increased at the designed rate, and the increase rate graally slowed down, and finally reached the limit of 21 million in 2140<

Introction to bitcoin in network
bitcoin is based on a set of cipher codes and generated by complex algorithms. This rule is not interfered by any indivial or organization and is decentralized; Anyone can download and run the bitcoin client to participate in the proction of bitcoin; Bitcoin uses electronic signature to realize circulation, and checks repeated consumption through P2P distributed network. The generation and consumption of each bitcoin will be recorded through the P2P distributed network and informed to the whole network. There is no possibility of forgery. Bitcoin does not rely on specific currency institutions to issue, 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 difference between bitcoin and bitcoin
it should be noted that

in English, the words bitcoin and bitcoin represent two concepts of payment network and monetary unit

bitcoin starting with capital B represents bitcoin network system or bitcoin network protocol, which is a payment system based on decentralized network

you can simply understand bitcoin as a public accounting system built on the Internet and not manipulated by any third party. Bitcoin, which starts with lowercase B, refers to the digital currency (e-money, e-cash, cryptocurrency) built on bitcoin network. Bitcoin is the payment accounting unit built in bitcoin payment system. We call bitcoin the network system that proces bitcoin<

in Chinese, bitcoin and bitcoin are both called bitcoin without distinction in many places

its main features are as follows:
1. 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< 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 required 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 in the end, a small transaction fee 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. Bitcoin is not completely anonymous

it will take some time to protect privacy when using bitcoin. All bitcoin transactions are publicly and permanently stored in the network, which means that anyone can view the balance and transaction records in any bitcoin address. Unless the bitcoin holder discloses personal information ring the transaction, the bitcoin address will not be associated with the real identity of the bitcoin holder. This is why it is recommended that bitcoin holders use multiple bitcoin addresses; In fact, you should create a new address each time to receive bitcoin. This is especially important when using bitcoin in public places, such as on websites. In addition, you can also consider using tools like tor to hide your IP address from being recorded.

7. Bitcoin is still experimental

bitcoin is an experimental new currency in active development. Although its experimentality is diminishing with its increasing usage, remember that bitcoin is a new invention, exploring ideas that have never been tried before, so no one can predict the future of bitcoin.

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

7.

Similar to futures contract, it is a trading method proposed by bitstar

the leverage of bitcoin virtual contract is shown as the leverage stability of the revenue level of legal currency: if you invest US $100, the revenue you can get = US $100 * the rise and fall of bitcoin * the fixed leverage ratio

assuming that the current price is 500usd / BTC, an investor can buy a BTC at the current price, and the principal is 500usd. At this time, the investor can make 50 more BTC virtual contracts

at this time, if the price of BTC rises to US $750, or 50%, the investor's contract income is 3.3333 BTCs, which can be sold at the current price to get us $2500, and the income is five times of the principal investment

bitcoin futures provided by bitcoin exchanges are usually traded in bitcoin. Futures is opposite to spot. Spot is a commodity that can be paid and delivered at the same time. In fact, futures is not "goods", but an agreement (contract) - futures contract that promises to deliver "goods" (subject matter) at a future time

extended data:

futures contract is an agreement that the buyer agrees to receive certain assets at a specific price after a specified period of time, and the Seller agrees to deliver certain assets at a specific price after a specified period of time. The price that both parties agree to use in future trading is called futures price

the specified date on which both parties must conct transactions in the future is called settlement date or delivery date. The assets agreed to be exchanged by both parties are called "subject matter". If an investor gains a position in the market by buying a futures contract (i.e. agreeing to buy at a future date), it is called long position or long in futures

On the contrary, if the position obtained by investors is to sell the futures contract (i.e. bear the contract responsibility to sell in the future), they are short positions or short on the futures

8. BTC refers to bitcoin, LTC refers to litecoin, and CNY refers to people's currency

BTC CNY LTC means RMB transaction between bitcoin and Leyte, which supports the free exchange among bitcoin, Leyte and RMB.

9. It's true that the output has been reced. It should be rare. There are no new mining machines yet. I'm looking forward to it. Super energy has potential.

10. Like stock ing, there are gains and losses. If compared with stock ing, the technical content is higher than that of stock ing, don't say it's a scam. SINOC is doing a good job now. The number of total mines and the total amount of money in the total mines are transparent!
