5.

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

6. Virtual currency includes digital cryptocurrency. Virtual currency includes game currency and digital cryptocurrency. Digital cryptocurrency only includes bitcoin, Leyte coin, Weimeng coin, doggy coin, Ruitai coin and Ruibo coin.

7. 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.

8. There are many advantages of encrypted digital currency. Here are two

1. Secure
transaction of cryptocurrency on the decentralized platform of blockchain, the E-wallet used by it is authorized to send and receive cryptocurrency by the cryptosystem using the unique public key and private key. And the account does not need to be identified by a third party, so outsiders can not know the identity of the trader
2. Tamper proof
after the transaction on the blockchain is confirmed, it is tamper proof, and this kind of data is traceable, so the illegal elements can't cheat by deleting or modifying the records
you can learn about cryptocurrency through some media platforms, so I won't go into details here.

9. The hottest time of encrypted digital has passed, and cryptocurrency was the hottest year in 2015. At that time, shortly after bitcoin entered China, people did not know much about cryptocurrency and worshipped it blindly. Now, people have graally become rational
since 2013, the popular digital currencies are bitcoin, Ethernet, lightcoin, DCT and so on.
