Instead of Copper I would use Palladium. How are all those different NTFs listed on an exchange? If each NTF is uniqute, wouldn´t the whole list of Spinvest NTFs be 100K entries long? I still don´t get the concept apparently, sorry for my ignorance. In principle you aim to sell small investments like a "card" worth 3,32 Spi of Gold. Will there be enough liqudity for all those mini investments without a "use case" like a real game behind?
