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

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

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
