You can try Polkadot instead of ETH. Polkadot is developed by Gavin Wood, he's very experienced. Polkadot can maintain a good position currently, where it has a good base to start growing once needed.
Polkadot is already developed very far compared to new projects because Gavin Wood has experience from ETH and now tries to build a solid coin, Polkadot.
switching over to alternative blockchain is easy, but what if the token and dapps that's available in eth didn't make their multi chain alternative and deploy their smart contract in something like polkadot it will be absolutely useless then, I think that's not good idea, if it's selecting alternative blockchain layer 2 will always be better.
