depends, but don't feed it to a high leveled servant.. cuz it's waste of QP.

it's fine to feed it to servant around level 1-30, It's fine to use Silver till level 40,, but from then on you better burn them to clear up space.

personally speaking I've been feeding them to low rarity servant, I'm not in that much rush to max their level but little by little their level will raise pretty signficantly before you realized it.
