Simply put: Gas fees is what you pay to process a transaction on the blockchain - buying an NFT, minting, or even adding funds to your wallet. It is similar to the bank fees you pay while withdrawing money/making a payment. These fees are added on top of the mint price/marketplace price and they go to the blockchain provider (Ethereum, in this case).

The main difference is between bank fees and gas fees is that you always pay gas fees if you're making a blockchain transaction.

On a more complex level, gas fees are required to be paid by all to keep the blockchain stable and running. They fluctuate according to the level of activity on the blockchain and it can be as low as $1 or as high as $100.
