This is the estimated fee you can expect to pay to have your bitcoin transaction confirm in 1 block. The estimation is derived from the daily total revenue miners received divided by the daily total number of transactions.
An option to change to a different currency is provided.
Notes on transaction fees: Most exchanges do not provide an option to change the fee amount, and charge a static fee. A notable exception is Deribit. The newer Bech32 wallet format, also known as native or SegWit, use a lower fee for the same transaction as legacy addresses. The addresses start with "bc1".
Mania was $60 USD to move bitcoin to an exchange you've only just heard of to buy a different coin with funny name :)
