As I know, Ethereum 2.0. is going to solve the problem of Ethereum's scalability and big fees. After launching Ethereum 2.0. this blockchain will be switched from Proof-Of-Work consensus, to Proof-Of-Stake. Coins that are working on this consensus have lower transaction fees, because it is easier to keep this network and validators get less rewards, so I expect that Ethereum will become cheaper and it will be easier to run small transactions.
