Why are pangolins so valuable?

Can you tell me why pangolins, these fascinating yet endangered creatures, are considered so valuable? Is it due to their unique and intricate scales, which have been traditionally sought after for their supposed medicinal properties? Or could it be their rarity and the threat of poaching that has driven up their value in the illegal wildlife trade? Perhaps there are other factors at play that contribute to their perceived worth. I'd be interested to hear your thoughts on this matter.
