it is not so easy to find a project that will eventually cost about as much as ETH, because there are a lot of projects based on smart contracts now, and the value of such projects is not as high as that of the founder in this area of ETH.
No project for now but for sure in the future, many will challenge ETH so there’s a chance for a new project to replace ETH especially if they failed on their updates. This is not a scam though and I don’t think this is centralized, they team works on this to be decentralized and this is why many supports ETH, we should not mislead other people here.
There are many ETH supporters because they know what ETH's power is.
Because the Ethereum blockchain has always collaborated with every project they build.
So even if someone says that if you wait there will be someone who can compete with ETH maybe because of the price but not with the blockchain system.
