Whenever there is a trending coin, People like to talk that"This coin is Ethereum killer". Now people talking about Solana(sol) that is a pure Ethereum killer. But I Dont believe Solona can do it. There is a lot of smart contracts/blockchain available nowadays but no one can able to bet on Etheruem. Sill most of the coins made by using Ethereum smart contracts and it's a good sign. Ethereum smart contracts are very popular and people also like them. The problem is about the high fees, But I hope this problem will be solved. Maybe Ethereum developers need more time for this to do.
