I successfully sent some cryptocurrency the other day. Then when I looked over my transaction, it had a gas amount or charge. What is this gas amount? I never heard of it and I don't even know what it is. Now is there anyway to avoid it or at the very least minimize it's amount? Please can someone give me some advice and steer me in the right direction!
Consider the example of etherium : The etherium is a network, a block. Etherium (ETH) is the fuel for the network. When you pass the tokens, interact with the contract, send ETH or perform any actions in the blockroom, you must pay for these calculations. The payment is calculated in gas, and the gas is paid to ETH.
* 21 000 - the gas limit for the standard transaction
