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
