⛽ "What is Gas Fee?" Think of it as... the gas cost to drive on the blockchain road!
When you ride a motorcycle or drive a car, you need to refill gas, right? No gas = no movement.
On the blockchain, every time you perform a transaction like transferring money, swapping, or minting an NFT, you need to "refill" it to keep it running. And the "gas" here is the Gas Fee.
💡 Simply put:
Sending money on the blockchain? You have to pay gas fees.
Using DeFi? Swapping tokens? You also have to pay gas fees.
Minting NFTs, voting in DAOs, staking? It still costs gas.
🏗️ Gas Fee is used to:
Pay for the computers (nodes) that execute and verify transactions.
Prevent spam, making users "serious" when performing actions.
📈 Gas Fee changes according to:
Network congestion: more users means higher fees.
Complexity of the action: the heavier it is, the more it costs.
⚠️ But keep in mind:
Transactions may fail if you pay too low a gas fee.
Some networks like Ethereum sometimes have extremely high gas fees, so people look for ways to switch to Layer 2 or other networks like BNB Chain, Polygon.
✅ In summary:
Gas Fee is the cost you need to pay to "refill" for transactions running on the blockchain; the more vehicles, the higher the fee!
