I hope ETH 2.0 will be released soon and transaction fee issue will be solved. We can't switch to another coin because most of altcoins now are based on ETH blockchain network.
Even with the ETH 2.0 launch, it will take at least a year for the transaction fees to go down because AFAIK ETH 2.0 will be launched in three phases. Phase 0 which is now phase 1 which is mainnet without smart contracts and phase 2 which will include smart contracts.
