Ethereum was launched 6 years ago, after that many new blockchains came along. And after that many new blockchains appeared, but none could replace Ethereum. Stellar is more senior than Ethereum, but it can be beaten by Ethereum. Basically Ethereum and Stellar have the same smart contract function. Is Dot better than any other coin that came out 7 years ago?
It could be better because the DOT can also see the shortage of coins that have been born in the past, but to compete with older coins, DOT takes a long time because the coins that have been popular from the past are old coins which are very powerful and difficult to match in the near future, because they also have their own development in terms of blockchain.
