This revision has failed testing.

I don't think this approach makes any sense. We want to do as follow:
1/ Define the priority based on utxo creation, size and age.
2/ Consider low priority transaction as free.
3/ When mempool is full, start ejecting low priority transactions.

Adding yet a new place where fee are handled is only making the whole situation more complex and convoluted.

I agree with what you've said. We'll need to do more shuffling to clean this up.

src/primitives/transaction.cpp
113 ↗	(On Diff #2532)	Looks like you need a ssize_t .
src/validation.cpp
791 ↗	(On Diff #2532)	I think we should count age as sum(coinage for all inputs) / sum(amount for all inputs)
810 ↗	(On Diff #2532)	I don't think the -1 makes any sense.

src/primitives/transaction.cpp
113 ↗	(On Diff #3175)	Tried this as a `ssize_t` but it was ambiguous under the current Amount `*` operators. Can add one for ssize_t if necessary, but it may overlap with other things on some platforms since it's a typedef.

I am considering dropping the minRelayFee some, and adding a base UTXO fee. So that for a normal transaction the minimum would be the same, but for ones with lots of outputs it would cost something extra.

I would like feedback on that idea.
