Alpha digital cryptocurrency

1. Cryptocurrency is not issued by legal tender institutions and is not controlled by the central bank.

2.

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

recommend an article: brief introction of the top 100 currencies in the market value ranking of digital currency. This article summarizes the brief introction of the top 100 currencies in the market value ranking (according to the market value ranking of coinmarket cap on July 30, 2018), hoping to be helpful to friends who have just entered the currency circle

3. There are many mainstream currencies in the Chinese market, some of which are fake. In terms of mainstream rankings, bitcoin, ethereal coin, Leyte coin and e-dinarcoin are generally used, while the rest are self copied in China, which is unstable and unreliable.

4. There is no perfect digital cryptocurrency, any kind of digital cryptocurrency is defective, including bitcoin. But at present, bitcoin is not the best digital cryptocurrency, but it is the most successful one. Other excellent digital cryptocurrencies include Wright coin, Ruitai coin, doggy coin, Ruibo coin, thousand gold card and so on.

5. This should be distinguished according to the research and development direction of the white paper on each digital currency. There are many types of digital currencies circulating in the market, including those for the Internet of things, data, new sources and transaction protocols. For example, LRC is a decentralized trading agreement, which is the trend in the future.

6. It's not particularly complicated, but it's easy to make mistakes without experience.

7. In theory, the pricing of digital cryptocurrency is determined by the market, but it is not feasible now
the traditional pricing of digital cryptocurrency generally starts from offline transaction. When the offline transaction reaches a certain scale, it will log on to the third-party transaction platform. The price of the online third-party platform is generally the price of offline transaction, and of course it may be influenced by the platform and the development and maintenance team
nowadays, the price of currency is basically decided by the developers themselves. For example, Ruitai currency is decided by the developers themselves, but it has entity credit endorsement.

8. There are not too many restrictions on the investment amount of digital cryptocurrency. It depends on the indivial's will. However, if you buy it on the trading platform, there are generally certain restrictions. Generally, the one-time recharge of the platform is at least 100 yuan. But if we are not talking about traditional digital currencies such as bitcoin, Leyte, Ruitai and Weimeng, but those direct selling currencies, it is not necessarily. The entry-level investment is different. There are thousands, hundreds and tens of thousands of them, so we should invest carefully.
