#GasFeeImpact The “gas fee” in cryptocurrencies, especially on the Ethereum network, is a fee paid to miners or validators to process and confirm transactions or execute smart contracts on the blockchain. It is measured in “gwei” (a fraction of Ether) and varies according to the network’s demand: the higher the traffic, the higher the cost. These fees ensure the network’s security and decentralization, but they require care. To avoid surprises, it is recommended to check the current fees in tools such as the “Ethereum Gas Tracker” before making transactions, adjust the “gas” value manually (if possible) to save without compromising speed, and avoid peak times on the network. In addition, paying attention to reliable wallets and platforms is essential to avoid falling for scams that exploit hidden fees or manipulations.
