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.
Ethereum 2.0 will indeed solve the problems that have been experienced by ETH users, one of which is regarding the expensive gas fees when making transactions because Etherum 2.0 will have a much larger capacity to accommodate the number of transactions in DeFi applications, but with Ethereum 2.0 it will take time about one to two years to bring about major changes in the Ethereum blockchain network, so with this update it is very likely that in the future gas transaction fees will become more stable.
