i don t contradict you with that but there is a solid market that searches for this product to buy? i don t see one and i tell you why, there are barely 100 exact searches for the term "nano jacket" and i don t see an increasing pattern in keyword planner tool either.
so i cannot contradict you fully that this product may become a high demand but that only on the distant future, till then, the domain doesn t worth more then the reg fee.
it s up to you if you want to let it go or hope that product will become in high demand in another time
