This is too high IMO. There may be use cases where the child bounty rewards need to be quite low (example) or at least disproportionally low to the total bounty.

I propose a fixed min of 10 * DOLLARS (which I believe is half the min of the main bounty).

Same as for Kusama

This is too high IMO. There may be use cases where the child bounty rewards need to be quite low (example) or at least disproportionally low to the total bounty.

I propose a fixed min of 5 * DOLLARS (which I believe is half the min of the main bounty).
