Gas Fee
The payment made to a blockchain network for the computation and storage a transaction consumes, priced in the chain's native asset.
What Gas Fee means
Gas is the unit that measures how much computational work a blockchain transaction requires. A simple ether transfer consumes 21,000 gas; a complex smart contract interaction can consume many times more. The fee paid equals the gas used multiplied by the price per unit of gas, denominated in the network's native asset and quoted on Ethereum in gwei, which is one billionth of an ether. Fees exist to compensate validators and to prevent the network being flooded with worthless transactions.
Since EIP-1559 Ethereum splits the price into two parts. A base fee is set algorithmically from how full recent blocks were, rising when demand is high and falling when it is not, and this portion is burned, permanently removing ether from supply. On top the sender adds a priority fee, or tip, which goes to the validator and determines how quickly the transaction is included. Users also set a maximum they are willing to pay, so a transaction can wait rather than overpay during a spike.
For anyone active on chain, fees are a real and volatile cost that has to be budgeted. During heavy demand a single interaction can cost tens of dollars, which makes small transactions uneconomic and can price users out of moving positions exactly when they most want to. A transaction that runs out of gas fails but still consumes the fee, so the money is spent for nothing. Layer-two networks exist largely to batch activity and reduce this cost.
Worked example
At a base fee of 20 gwei plus a 2 gwei tip, a 21,000 gas ether transfer costs 0.000462 ETH; the same transaction during congestion at 200 gwei costs roughly ten times as much for identical work.

Trade with a regulated broker
Understanding the terminology is the cheap part. The expensive part is choosing a counterparty whose execution, financing and withdrawal behaviour match what the marketing implies. Every broker below has been reviewed with a funded live account, and each review states which legal entity and which regulator applies to the account you would actually open.
