It's getting annoying to see people talking about a project is the next Ethereum killer, for how long are we going to keep this up? So far there are so many ETH killers that haven't taken a single shot at Ethereum, this has proven that Ethereum isn't a project that any new coin or token can just take over like that, it has never been easy.
are you sure it will stay that way in the future?
the only thing unique about ethereum right now is that they still use POW. but if you look at the technology, I'm sure ethereum is lagging behind. so when eth has migrated to POS it will look the same. and that will make the competition even hotter, maybe ethereum will be abandoned, because they haven't been able to solve the problem of network fees even though they have switched to PoS consensus. so about the ethereum killer is not really a bullshit. solana, Avalance, and other smart contract projects could really be the ethereum killer if ethereum couldn't solve their problems.
Its true that Ethereum is a bit behind the recent altcoins. But what makes you think that Ethereum will be superseded and eliminated by Solana, Avalance?. Ethereum is working hard and converting to ETH2.0, they are not stupid enough to stand still and let other altcoins take over.
With slow processing speed and high gas fees, ETH is currently the most secure and decentralized ecosystem. ETH remains the top choice of developers and large institutions.
Solana and new ecosystems have left some decentralization in exchange for transaction speed. This would be very risky for the users, I remember correctly the SOL network went offline for 17 consecutive hours in 2021 and forced them to restart the whole system.
