So if anyone is like me, they've shelved out thousands and thousands of glimmer to both Xur (for upgrades) and the Gunsmith (for ammo synths) and are even stockpiling their House Banners / Silken Codex / etc for a rainy day when you are in need of cash and don't have the time to farm it. What if there was a rare consumable item that would program your glimmer into being worth twice as much as normal? It would last 10 minutes and would allow for quicker weapon and armour upgrades and make purchasing high value items in stores more affordable for a short amount of time. It would be obtainable from any location you can get Strange Coins (other than the Weekly Heroic Reward), so blue engrams mostly, and Xur might decide to sell it from time to for 5 Strange Coins each. The item could even have its own backstory about being an illegal underground ghost modification that when in circulation caused the economy to fluctuate sporadically. We have guns that are supposed to be destroyed on sight, so it would fit in quite nicely. It would also explain why some vendors charge so much for certain items, as a direct result of being victim to this "inventory exploit". Just a thought anyway...
