im neewbie in this
but
as for me
Miner fee - its fee for your mine process, not?
And the same for service fee, that general fee for any transactions
Refer to this explanation dude:
Miner Fee: Fee that goes to the Miner for adding your transaction in a Block.
Service Fee: Fee that goes to the Service Provider, e.g. BitMex or Binance, for using their service.
That is the simplest explanation for the question.
