BPG coins are just a native token for the platform, an incentive of fee discounts, maybe dividends etc are derived from their usage and secondary, if valued enough, traded on other markets and held as speccy assets like Binances token..
So as for a store of value, not the best, so the gold backed coins are in a different asset class really n dont serve any real value other than ease of storage rights, irrefutibility n easy transfer of title..
I chucked an article up above re exchange native tokens btw if ya missed it
