In the real world, there are some assets that maintain a relatively constant value with respect to inflation. This provides an easy way for people to liquify or solidify their wealth as needed.
The closest things to glitch that would match this are ingots (ie the molybednum standard). Unortunately Ingots, like everything valuable in the glitch world, can only be redeemed for a fraction of their value. Rather than change the implementation for established resources, how about adding functionality to an existing item?
If the 1M trophies could always be bought or *sold* for 1M at the vendor, it would give wealthy players a physical way to display their wealth without "losing" it to a form that isn't spendable in the future. Plus, let's be honest: aren't decadent displays of wealth the reason this trophy exists in the first place? I wouldn't mind having 3 or four of them sitting on the desk in my tower.
