Gas fees are the payment you make to use a blockchain network.

Think of the blockchain like a busy road and each transaction like a car. When many people are using the road, you may need to pay a higher toll so your transaction gets processed faster.

On networks like Ethereum, gas fees help pay the computers that verify and record transactions. The fee can change based on network demand and how complex the transaction is.

Why it matters: if you send $ETH or use a dApp, the gas fee is part of the total cost.

Takeaway: before you confirm a transaction, always check the gas fee so you know the real cost. #Crypto #Blockchain
