🔥 Crypto essentials: Gas fees
Gas fees mainly depend on how congested the network is: each block can only fit a limited number of transactions, so the more people want to use the network, the higher the base fee automatically gets.
If you're not in a hurry, try to avoid busy times when making transfers—Gas fees are often much lower then.
$ETH is the native currency used to pay Gas fees on the Ethereum mainnet.
