Is there digital cryptocurrency in China
Cryptocurrency is not a tangible currency that can be carried with you, but a digital asset that can be exchanged“ The "encryption" part comes from using encryption technology for security and authentication ring a transaction
when using cryptocurrency for exchange instead of legal tender, crypto owners do not have to rely on banks to facilitate transactions, and can successfully avoid the costs of using financial institutions
generally, cryptocurrency transactions are processed and completed through the blockchain network. The blockchain is designed to be decentralized, so each computer connected to the network must successfully confirm the transaction before it can process it. Ideally, this would create a more secure transaction for all involved. It can also cause you to wait for a while; One of the big complaints about bitcoin is how long it takes to complete the transaction
domestic cryptocurrencies include bitcoin, Ethernet, Leyte and e-dinarcoin
extended data:
bitcoin: the concept of bitcoin was first proposed by Nakamoto in 2009. It is a P2P form of digital currency. Bitcoin is generated through a large number of calculations according to specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, And the use of cryptography design to ensure the security of all aspects of money circulation
ether coin: ether coin (a digital token of Ethereum, regarded as "bitcoin version 2.0"), can be bought and sold on the trading platform

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 immatureXRP
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
