Average fee paid per transaction size, in Satoshi/byte
Bitcoin Cash (BCH) transaction fees are paid to miners who confirm transactions by including them in a mined block.
Miners typically assign priority to transactions with higher fee rate. Because Bitcoin Cash (BCH) on-chain capacity is higher than Bitcoin Cash (BCH) demand for on-chain transactions, transactions sent with a low fee (1 satoshi per byte) will usually be included in the next block. This was true for Bitcoin before the scaling forks of 2017, but is no longer true for Bitcoin Core (BTC).
Bitcoin Cash (BCH) transaction fees are measured in Satoshis per byte (0.00000001 bitcoin per 0.000001 Megabyte) because memory space on the blockchain is the limiting factor. Several factors may influence the size of a Bitcoin Cash (BCH) transaction in bytes, however the value of the transaction in Bitcoin Cash (BCH) is not usually correlated (a typical transaction sending 1 Bitcoin Cash (BCH) is usually about the same size in bytes as a typical transaction sending 100 Bitcoin Cash (BCH), and will need to have about the same fee to receive the same confirmation priority).
