Yes β sending 1 ETH or 923 ETH costs the same fee. The amount doesn't change it; the action and network do. But as a share of what you send the fee is brutal on tiny transfers and nothing on big ones β that's what the last column shows. Layer-2s (Arbitrum, Optimism, Base) settle to Ethereum for a fraction of the cost. Live data, refreshed every 30s.
Gas in plain terms
Gas is what you pay to get a transaction included on Ethereum. The price moves with demand: quiet hours are cheap, a hyped mint or a market crash can spike it 10β50Γ. The gwei number is the price per unit of gas; multiply it by how much gas your action needs (a simple send is 21,000, a swap far more) and the current ETH price, and you get the dollar cost above. If you trade on-chain, checking this before you click saves you from overpaying on a busy block.
Trading leverage instead? Your bigger risk isn't gas β it's liquidation. See exactly where you'd be liquidated with the liquidation calculator, and size from risk with the position size calculator.
