This is because a Litecoin Satoshi is about 1/10th of a BCH Satoshi i USD value.
Both chains have a min. fee of 1 sat/byte.
There has been a proposal for BCH to allow for a certain
| amount of 0 sats/byte txs in a block. Maybe contacting the node devs from BCHN, BU, BCHD etc. and ask if this is something that is still on the table..?
