Fees Per Tx (BTC)
Daily median transaction fee statistics per transaction and block, excluding coinbase transaction (miner reward). A bitcoin fee is added by the user to a transaction to incentivize miners to include that transaction in their block. Block space is limited, so bitcoin fees will change based on demand.
