$ETH
Since one qwei equals one-billionth of an ether (0.000000001 ETH), it offers a practical method for calculating and displaying small transaction fees on the network, much like Bitcoin’s smallest unit, the satoshi. Fees on the Bitcoin network have also declined recently, with transfer activity falling to levels not witnessed in years. Currently, a high priority transfer on Bitcoin is 3 satoshis per virtual byte (sat/vB), which amounts to $0.41 at the time of writing.
