As an investment proct, digital currency cannot develop without trading platform, operating company and investment company

On the one hand, the blockchain technology it relies on has been decentralized 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 stability

bitcoin (BTC)

issue date: 2009

market value: US $163 billion

advantage: as the first cryptocurrency issued, bitcoin is the world's largest and most popular blockchain network and the most experienced cryptocurrency that can resist hacker attacks

disadvantage: the increasing demand brings great pressure to bitcoin network, which makes the transaction cost high. The system can only process about seven transactions per second, but its power consumption is amazing. This is mainly e to its workload proof mechanism and consensus principle, which makes mining become a labor-intensive activity

eth

release date: 2015

market value: US $70 billion

advantage: its built-in programming language allows developers to write their own smart contract computer programs running on the blockchain. So far, most of the first token sales are based on Ethereum's smart contracts

Disadvantages: Ethereum also uses the consistency protocol of workload proof, so it is relatively slow and consumes a lot of power. Many early smart contracts are vulnerable to hacker attacks, and the development of smart contract security is still immature

XRP

issue time: 2012

market value: US $32 billion

advantage: XRP claims that its XRP cryptocurrency can become the "bridge currency" of major financial institutions, and can settle cross-border payments more quickly and at lower cost. Ruibo uses a new consistency protocol, which can achieve faster transactions, faster than t-coin and Ethereum

disadvantages: as a private company, Ruibo has important control over the system, some people think that XRP is not decentralized enough, which is in contrast to bitcoin, which anyone can mine

bitcoin cash (BCH)

issue time: 2017

market value: US $19 billion

advantage: this kind of currency is a "hard fork" of bitcoin, and its founder has adjusted compared with bitcoin, so that it can handle a larger transaction volume

disadvantage: critics say bitcoin cash is too centralized - a few miners create most of the money

lightcoin (LTC)

time of issue: 2011

market value: US $10 billion

advantage: lightcoin is a kind of "alternative currency" - almost a clone of bitcoin, but there are still several differences. Lightcoin processes transactions four times faster than bitcoin, and the mining process remains open to amateurs - very different from bitcoin, because bitcoin's professional miners use expensive hardware

disadvantages: although it is faster than bitcoin, lightcoin is still too slow and consumes a lot of power. These factors make it unable to become an ideal payment method, and there is another disadvantage: it is not very famous

5. In Internet terms, the full name is device generated content, which means device driven content. The concept of DGC originated from the wearable field, which was proposed by flashunit flash point. It represents that different wearable terminals can give users different functions, meet the needs of all aspects of life, and constantly create new life application scenarios
however, the DGC of digital currency is a shared currency, and there is no application in China. The so-called application is just a cover. There are not many digital currencies in China. Ruitai currency is regarded as asset mortgage certificate, micro union currency and micro business. There is a certain relationship between them, but it is a bit of a drag to talk about application.

6. Digital cryptocurrency generally refers to the currency that can obtain certain rewards by solving encryption problems through computers. These currencies are generally open source and the information is open and transparent. Bitcoin is the most typical example. Others like Ruitai coin, Laite coin, dog coin, thousand gold card and so on.

7. I think the financial transaction here refers to the equity transaction in the primary market, that is, IPO. As a shareholder, you own shares, so this part of the money is still yours in theory, but the company can use this part of the money. Borrowing means that you give the money to the company. This part of the money is not yours, because you are not a shareholder. But the loan contract gives you another right, that is, to recover the principal and interest at a specified time.

8. The environment of 2016 and 2017 is destined to be the year of virtual currency, and no one can stop it! On December 28, 2015, the world virtual currency Summit Forum was held in Shenzhen. On January 20, 2016, Zhou Xiaochuan, the Central Bank of China, announced that virtual currency would break out in China. On March 20, 2016, the world's 50 central banks held a meeting in Shanghai to discuss the development and links of digital virtual currency... Digital virtual currency has come with thunder! Don't waste our time waiting and swinging. If we miss these two years, we will miss another era!

9. Tic is not a real cryptocurrency. Real digital encryption must have the following three characteristics:
1. The source code of digital currency is open source and anyone can view it
2. The total supply is constant and cannot be modified
3. The price is determined by the market, and there is no such thing as only rising but not falling
of course, except for the crowdfunding projects of the European crowdfunding platform, these tokens are just a kind of asset voucher.
