Why is there a gas fee?
the unit that measures the amount of computational effort required to execute specific operations on the Ethernet network.
Gas is what Ethereum uses to incentivize miners on the network. Every transaction has a gas cost, which is paid in Ethereum, and it measures how much computation is required for certain transactions. Miners can get paid a certain amount of gas fees for part of their role.
What is a gas limit?
A gas limit is the maximum amount of gas you would be willing to use in a given transaction, the higher the amount the faster the transaction will complete. If the amount is too low, the probability that it may not be processed.
Is there a way to avoid paying for Gas?
Currently no.
Who Receives Gas Fees?
Gas fees are payments made by users to compensate for the computing energy required to process and validate transactions on the Ethereum.
conclusion
since the the Ethereum is a decentralize network they need people to verify the transaction and reward them with the gas fee. the higher the transaction in the network the higher become the gas.
