If you could trade anything, what would you trade? Probably the things you care about most. I care about the price of DDR5 (damn you Apple, for, upping Mac prices!!!), so I made a market for it on Perpify. Now I trade it. Spin up a perpetual future on anything, own it, and collect fees every time someone trades it. Or just trade the ones already out there, like my DDR5 market, hehe!
