Users pay gas fees to compensate for the computer power needed to process and validate transactions on the Ethereum network. A larger gas limit means you'll have to put in more effort to complete an ETH or smart contract transaction. When the network gets busier, transaction costs for Ethereum (ETH) rise. This is due to an increase in the number of people conducting transactions such as sending tokens and trading. This is due to an increase in the number of users sending tokens, trading on DEXes, and depositing their assets on loan platforms.
