Katcoin bitcoin
was released on October 7, 2011. It is currently the highest market value counterfeit coin, about 1% of BTC's market value, or US $1000W. Compared with BTC, LTC is faster, with an average of 2.5 minutes and 6 confirmations per block in 15 minutes. In addition, the number of LTCs is four times that of BTCs, with a total of 8400w. At present, LTC uses scrypt algorithm, which needs a lot of memory support. The professional mining machine on the market can not be used for LTC mining, only the graphics card
what is the difference between lightcoin and bitcoin
1. Transaction: easier to use, larger volume and greater appreciation potential. The block confirmation time is shorter, which is four times faster than bitcoin. For example, pizza owners are more willing to accept LTC payment to save transaction time< Mining:
special algorithm creates the unique charm of LTC, which is also the key to stand out from Shanzhai coins. Scrypt algorithm uses sha256 as its subroutine, and scrypt itself needs a lot of memory, each hash is used as the input seed, and then needs a lot of memory to store another seed pseudo-random sequence, Generate pseudo-random points of sequence and output hash value. The key is that scrypt algorithm needs a lot of memory while sha256 algorithm does not. So in this era when BTC mining of graphics card is coming to an end, LTC mining is about to usher in a golden period of development. Because of the high cost of memory, any ASIC or FPGA has no advantage over graphics card mining. LTC has advantages, at least in the foreseeable future
3. The biggest threat of bitcoin is 51% attack:
some shanzhais are killed by 51% attack. To be honest, LTC is a worry for the development of LTC and BTC, of course. However, the specific problems they face are different: BTC can avoid 51% attack through technology upgrading (such as end block reconstruction, careful node upgrading, and calculation difficulty), However, there is no way to evade LTC technology. However, e to the scattered computing power of graphics card mining and the increasing difficulty, this problem needs to be paid attention to, but don't worry too much. With the use of ASIC in BTC, the risk of 51% attack is increasing. I hope BTC development team can solve this problem as soon as possible.
The earliest is a kind of network virtual currency. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals. In 2013, the U.S. government recognized the legal status of bitcoin, making the price of bitcoin soar
< H2 > extended information:bitcoin is e-cash similar to e-mail. Both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address
starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique
many websites for technology players have begun to accept bitcoin transactions. Websites such as mtgox and btcchina, as well as some Taobao stores, can even accept services such as bitcoin exchange for us dollars and euro. There is no doubt that bitcoin has become a real currency in circulation, rather than a virtual currency like Tencent Q coin
according to the notice and announcement issued by the people's Bank of China and other departments, virtual currency is not issued by the monetary authority, does not have legal compensation and mandatory monetary attributes, is not a real currency, does not have the same legal status as currency, cannot and should not be used as currency in the market, and citizens' investment and transaction of virtual currency are not protected by law

1. Litcoin (LTC) is an improved version of digital currency inspired by bitcoin (BTC). It was designed and implemented by a programmer who worked in Google. It was released on November 9, 2011. Lightcoin and bitcoin have the same implementation principle in technology, but the creation and transfer of lightcoin is based on an open source encryption protocol, which is not managed by any central organization
2. Sunshine coin (SSC for short) is sponsored by Liu Chunyang, vice president of Jinhua express delivery Association of Zhejiang Province, instrial entrepreneur and philanthropist of express delivery instry. As a legal person, Zhejiang Dongyang Yueyin Technology Co., Ltd. is registered with the formal instry and Commerce Bureau, with a registered capital of 10 million yuan. With this as the backing and support, the sunshine elite team affiliated to the company launched the first virtual coin sunshine coin
The English name of Vicat is onecoin, which is a kind of Internet virtual currency term created by the government and is suspected of pyramid selling fraudin 2017, CCTV announced the list of 350 fund pyramid schemes, with Vicat in the list
in May 2018, Zhuzhou County Procuratorate of Hunan Province prosecuted the last four suspects involved in the third batch of the "3.15" Vicat money online pyramid scheme case supervised by the Ministry of public security to the court
4. Amazon coin
Amazon announced in early February 2013 that it is expected to launch Amazon coins in the United States in May 2013. Amazon coins is a new virtual currency that allows U.S. users to buy apps, games and props in the kindle fire. Amazon will provide tens of millions of US dollars of Amazon coins at that time to let users try and consume the apps, games and props in the app on the kindle fire for free
5. Eth is a kind of digital token of Ethereum, which is regarded as "bitcoin version 2.0". It adopts the blockchain technology "Ethereum", which is different from bitcoin. It is an open-source public blockchain platform with intelligent contract results, and a resonance network composed of thousands of computers around the world. Developers need to pay eth to support the application. Like other digital currencies, ether currency can be bought and sold on the trading platform
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
according to the currency conversion ratio on January 3, 2020, one bitcoin = RMB 47000
compared with fiat money, bitcoin has no centralized issuer. It is generated by the calculation of network nodes. Anyone can participate in the proction of bitcoin, and it can circulate all over the world. It can be bought and sold on any computer connected to the Internet. No matter where they are, anyone can dig, buy, sell or receive bitcoin, And in the transaction process, foreigners can not identify the user's identity information
the global financial crisis broke out in 2008. On November 1, 2008, a person who called himself Satoshi Nakamoto published bitcoin white paper "bitcoin: a peer-to-peer e-cash system" on the P2P foundation website, stating a new idea for e-money bitcoin came out. On January 3, 2009, bitcoin Genesis block was born
whenever bitcoin comes into the view of mainstream media, mainstream media always ask some mainstream economists to analyze bitcoin. Earlier, these analyses focused on whether bitcoin was a scam. Now the analysis focuses on whether bitcoin can become the mainstream currency in the future. The focus of the debate is often on the deflationary nature of bitcoin
