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.
So far, that is only the way they promote and make the new projects as competitors of Ethereum higher and higher. Although some older projects that want to compete with Ethereum, cannot. Although we know that sometimes, the projects serve better services, speeds, and also low fees, in fact,they cannot still beat Ethereum.
There is only a few approaches but not killing, like Binance or BNB, they are competing, but not killing for now... Just let it be, let others there with their pross and cons.
Remember before the rise of claim of ethereum killers, there were a lot of old projects claiming to be bitcoin killers? But where are they now? Most of them are dead and forgotten. But when it comes to eth competitors, at least they are trying to survive in this market. Just look at BSC, SOL, MATIC - they are pretty solid platforms that are already up and running offering cheaper fees. But surpassing ETH network is still far. And once ETH resolved their gas fee problem, I believe people will go back again to this network. But at least, with the rise of its competitors comes other alternatives for crypto users.
