1. virtual currency refers to non real currency. Well known virtual currencies, such as online currency of Internet company, q-coin of Tencent company, q-point and voucher of Shanda company, micro currency launched by Sina (used for micro games, Sina reading, etc.), chivalrous Yuanbao (used for chivalrous road game), silver grain (used for bixue Qingtian game), and popular digital currencies in 2013 include bitcoin, Laite coin, infinite coin, quark coin, zeta coin, etc Barbecue coins, pennies (Internet), invisible gold bars, red coins, prime coins.

2.

The use of digital currency license: 1. Packaging platform, good publicity 2. Developing OTC legal currency business of exchange currency trading and contract futures 3. Platform compliance, risk aversion

the commonly used licenses are: MSB of the United States, Estonia (al license digital currency trading license and wallet license), MSB of Canada, Australia, caymann, Singapore, Malaysia, Saint Vincent Philippines, etc

the license of each country should be applied by the local company, or the company can be registered before applying for the license. It can also register with the Singapore foundation, and lawyers can issue legal opinions on the project white paper

3. Bitcoin, of course, is the hottest one. In addition to bitcoin, there are also:
1. Litecoin is similar to bitcoin, which is also an encrypted digital currency, and its price has risen sharply recently. It is a P2P open source digital currency, which can be regarded as a branch of bitcoin. However, although lightcoin is based on bitcoin protocol, it does not require very high computing power. It can also be mined using ordinary computers. Lightcoin's algorithm comes from the algorithm designed by Dr Colin Percival for tarsnap secure online backup service (backup for Linux and other open source operating systems)
2. Namecoin
namecoin is also based on bitcoin, which is another branch of open source. Namecoin is a distributed DNS protocol -- generally speaking, it can transform the website name (such as ifeng. Com) that can be understood by human into the address that can be understood by machine. As its own DNS, this kind of currency can operate outside the normal Internet, so it can break away from the control of ICANN
the monetary value and domain name of namecoin are stored in the user's blockchain records, limiting the total number to 21 million
3. Peercoin
peercoin is a peer-to-peer variant of bitcoin, which can improve mining efficiency and security, and improve safeguard measures to avoid group mining. Now, group mining has been considered as a potential defect of bitcoin. According to the statistics of emerging currencies by coinmarketcap.com, peercoin currently ranks fourth in the market value of digital currencies
4. Primecoin
primecoin is a cryptocurrency similar to bitcoin, but it uses a completely independent mining algorithm. Bitcoin uses the hashcash algorithm, while prime coin uses the long Cunningham chains to create the value of money - a sequence of prime numbers named after mathematician AJC Cunningham
in the process of bitcoin mining, as the amount of money goes on, the difficulty will increase sharply. But prime is different. Every time a primecoin is mined, the mining difficulty will increase slightly, and the process is much more stable< 5. Feathercoin

based on the design of litecoin, released in April 2013, can adjust the mining difficulty more frequently than litecoin. Feathercoin will be updated frequently, adding new features and improvements to eliminate malicious mining behavior

6. Novacoin

another P2P digital cryptocurrency. Novacoin is different from most other currencies in that it integrates a protection mechanism in the currency core, which can identify illegal mining activities

the total number of novacoin is limited to 2 billion, which is considerable. If necessary, the total can be adjusted upward

7, infinitech

published in June 2013. A by-proct of litecain. According to the mining situation and the total amount of money, infinite money can frequently adjust the mining difficulty ratio< Megacoin was only released in the fourth quarter of 2013, imitating bitcoin in the early stage. The total number of megacoin is limited to 42 million, which can be mined like other virtual currencies. Its biggest selling point is brand publicity, which other digital currencies lack< It was released in 2013 and is still in its infancy. In the security part of quarkcoin, nine independent loops are deployed and six different algorithms are used.

5. I can't give you an accurate answer to this question because digital currency covers too many aspects. There is also the possibility that many new cryptocurrencies are born or die every day. Now the world's more well-known digital currencies are bitcoin, dogcoin, Leyte coin, bitstock, reborn coin, Yuanbao coin, Diandian coin and so on. It is said that Ecuador, a small South American country, recently created its own official cryptocurrency
according to incomplete statistics, more than 200 counterfeit coins have been proced since 2014, and more than 100 have survived. The life cycle of Shanzhai coin is generally about 2-3 months. Because the purpose of some Shanzhai coins is to earn money without any innovation. When the price is high enough, the makers will sell a lot to cash out. Without the support of the makers, this kind of counterfeit money will eventually die.

6. There are more than a few kinds of real digital currencies in the world, but there are thousands of them, among which the well-known ones are bitcoin, Leyte coin, Ruitai coin, Qianjin card, doggy coin, Ruibo coin, dark coin, diandianbi, apple coin, Yuanbao coin, prime currency, bitstock, bityuan, etc.

7. According to the roadmap published on the official website, there are two major branches, one is the expansion of underlying functions, the other is the optimization of user experience. The underlying function expansion is mainly to develop new functions on the basis of peer-to-peer payment to support the long-term vision of a real Internet of value (IOV). For example, expand Op_ Return, optimizing the cache architecture for balance, anonymity on the chain, and native protocol component based on op code are designed to support the implementation of functionality
there are two main reasons why user experience optimization is listed separately. First, LBTC wants to build an excellent peer-to-peer e-cash system. Its basic idea is to put payment experience and user first, so it puts it at a high level, such as cross platform light wallet, accelerating payment confirmation speed, optimizing irreversible block mechanism, etc. Second, LBTC has always emphasized superior chain governance system. Before that, there was a standardized SGS (spark governance system) governance system, but it still needs to constantly improve the relevant mechanisms. For example, we should greatly optimize the node parameters and election mechanism, establish the LBTC foundation, multi-channel proposal process, and light wallet's support for the governance function on the chain.

8. If you don't have herobrine mod, we suggest you use fishbone mining. That is to dig one grid down and three grids forward. Then dig one layer down in the third grid, and then dig three grids forward. It's like this. After digging, it's like ladder type. It's more likely to dig a drill, but it's also more likely to dig a place close to the monster

9. What is the classification standard? Now the coins that come out one by one are not good. In fact, they are pits. I think only bitcoin can be called a real digital currency
