I think this is possible because if you look at the back 5 years you will realise that how crypto market has changed in the last 5 years and nobody knows what will happen in coming next 5 years so I think there is a high chance to beat ethereum by any other cryptocurrency
Well this is I think, theres a tendency that eth will be replace in the future. A lot of changes happening in crypto and also with this defi projects that makes the fees of eth really expensive. That's true nobody knows what will happen indeed but hoping eth will still be the top in the market.
