The most characteristic digital currency
compared with traditional bank transfer, remittance and other methods, digital currency transaction does not need to pay fees to a third party, and its transaction cost is lower, especially compared with cross-border payment which provides high service charges to payment service providers
2. Fast transaction speed
the blockchain technology used in digital currency has the characteristics of decentralization, High anonymity
in addition to the point-to-point transaction without intermediary participation, one of the advantages of digital currency over other electronic payment methods is that it supports remote point-to-point payment, It doesn't need any trusted third party as an intermediary, and the two sides of the transaction can complete the transaction in a completely strange situation without mutual trust. Therefore, it has higher anonymity and can protect the privacy of traders, but it also creates convenience for cyber crime, which is easy to be used by money laundering and other criminal activities
Digital currency is characterized by low transaction cost, fast transaction speed and high anonymity

compared with traditional bank transfer, remittance and other ways, digital currency transaction does not need to pay fees to the third party, and its transaction cost is lower, especially compared with the cross-border payment that provides high handling charges to payment service providers
2. Fast transaction speed
the blockchain technology used in digital currency has the characteristics of decentralization. It does not need any centralized organization similar to the clearing center to process data, and the transaction processing speed is faster
3. High anonymity
in addition to the point-to-point transaction without intermediary participation, one of the advantages of digital currency compared with other electronic payment methods is that it supports remote point-to-point payment, and it does not need any trusted third party as intermediary, Both sides of the transaction can complete the transaction in a completely unfamiliar situation without mutual trust, so they have higher anonymity, which can protect the privacy of traders. But at the same time, it also creates convenience for cyber crime, which is easy to be used by money laundering and other criminal activities
extended data
the impact of digital currency:
digital currency is a double-edged sword. On the one hand, the blockchain Technology it relies on realizes decentralization and can be used in other fields except digital currency, which is one of the reasons why bitcoin is popular
On the other hand, if digital currency is widely used by the public as a kind of currency, it will have a huge impact on the effectiveness of monetary policy, financial infrastructure, financial market and financial stability1. Enjin (enj)
in the near future, the game instry is the instry most likely to adopt blockchain on a large scale. Enjin coin is the cryptocurrency of virtual goods created by Enjin. Enjin is the "largest online gaming community platform" with more than 250000 gaming communities and 18.7 million registered gamers
Cardano (ADA)compared with Ethereum, EOS and Tron, Cardano is the third generation of decentralized app (DAPP) and smart contract platform. Cardano's design philosophy has the following points:
scalability: with the growth of users, the transaction processing speed is not affected or even faster, such as P2P protocol
interoperability: in the future, there will be countless devices connected to each other, instead of only connecting and forwarding through routers. All kinds of devices can communicate directly through standard general protocol
Sustainability: like bitcoin, Cardano project will not be controlled and influenced by a certain company or organization, which is a safe, decentralized and sustainable development platform
With the popularity of sto (security token offers), Nash also plays an important role. Nash is a kind of registered security token. In the past, Nash participated in and led the development of many projectsNash exchange is a decentralized exchange. If you hold nex token, you can calculate the dividend here
4. Basic attention token (BAT)
bat mainly solves the problem of advertising:
user information is abused: large companies such as Google and Facebook track and use user information and behavior, and sell without the knowledge of users
the effect of advertising is restrained: middlemen earn most of the fees, a large number of advertisements are blocked by users using software, and advertisements are fake
in the past six to 12 months, the number of publishers using the brand browser (Note: the brand browser supports bat token) has grown rapidly, and almost no blockchain ecosystem has grown so fast
5, chainlink (link)
chainlink mainly solves the problem that each blockchain has and the smart contract cannot obtain external data. In order to introce external data into the blockchain, the concept of Oracle is proposed in smart contract
companies including Google are supporting the development of chainlink. Here is a list of chainlink partners
one of the main problems of chainlink is similar to Ethereum. The development team has reserved 650 million link tokens, while only 350 million are in circulation at present
Ethereum (ETH)Ethereum has long occupied the second place in the top 100 cryptocurrencies. Its ecology is so big that we can't call it altcoin now. To tell you the truth, I'm not optimistic about Ethereum in the long run, but it will flourish in the short run
digital currency is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of a specific virtual community. The European Banking authority defines virtual currency as a digital representation of value, which is not issued by the central bank or authorities, nor linked with legal currency. However, because it is accepted by the public, it can be used as a means of payment, or it can be transferred, stored or traded in electronic form

digital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English and the alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy
digital currency is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold. Today's digital currency, such as bitcoin, lightcoin and ppcoin, is an electronic currency created, issued and circulated by check sum cryptography. It is characterized by the use of P2P peer-to-peer network technology to issue, manage and circulate currency. In theory, it avoids bureaucratic examination and approval, so that everyone has the right to issue currency
digital gold currency is a kind of physical currency, and its deposit is measured in gold rather than legal currency. Therefore, the purchasing power fluctuation of digital gold currency is related to the gold price. If the price of gold goes up, it becomes more valuable. If the price of gold goes down, it loses value. Since there is no specific financial regulation to regulate digital gold money suppliers, they operate in a self regulatory manner. Digital gold money suppliers are not banks, so banking regulations are not applicable. However, the global digital currency Association, founded in 2002, is a non-profit association of online currency operators, convertors, merchants and users. This association supervises the users' reports and ratings the reputation of the convertor. The rating operation is confirmed by the users' reports
